2 @mr.hong are we doing the snow ball toss tomorrow? Do we need to bring a shovel?

Mr. Hong

2/11/2019 04:33:05 pm

@ DY - You will be building a snow structure.

2/11/2019 05:10:34 pm

so do we need to bring a shovel and are we going to do to do a snow toss game???

PKM

We tried different ways but didn’t work so we tried somthing random then it worked randomly so were happy about that and also didn’t know it was going to be that hard and thought it was going to be easy. After that we went and get are materials such as batteries, wires , and lightbulbs then after we got are materials we tried different things and was not a success and then minutes later we did it by trying out random things and it just worked and was not expecting that. Couple of days later we went and try new ways on how to light a lightbulbs and we used and try stacks of batteries wondering if you try stacks of batteries will it bright lighter?. Then we got some more wires then eventually some more batteries which we got about 5-6 batteries and worked which was a success and also we aware the lightbulbs might blow up if you add too many batteries but probably won’t do an explanation but the lightbulbs might never work again or just might take a while for it to rest. I have seen this in the internet known as “ YouTube “ which I didn’t know we would do an experiment on this and hoping we might do another one that is actually easy or hard and can be either one of those.

i wonder where is your hypothesis?

Adrian

2/11/2019 04:53:53 pm

In the first Science Challenge, we were required to use a wire, a battery, and a small tiny light bulb to light the bulb. At first, I thought about this challenge will be simple for me. I thought I can do it within a minutes. However, the result proved me wrong. I can’t even hold the wire with the battery because it was too hot. Even when I have already used tapes to hold the wire with the battery, I still can’t light the light bulb. I have tried to connect the wire with the battery with the light bulb, but it still doesn’t work. I keep on trying to connect them in different ways. It is really challenging for me. Once I tried not to connect both sides of the battery from the bottom place of the light bulb. I put the wire on the metal part, and it lights up in a sudden.

I am so excited that time when I succeed. I think the hypothesis statement is. If you connect the wire through the battery and the light bulb, (not connect with the same place of the light, and that won’t work) they will become a trail or a cycle and it will work. A battery has a positive and negative side. We have to put the light bulb (the bottom part) on whichever side. After it, connect the opposite side of the side where you put the light bulb on it, with the metal part of the battery with a wire. It should work on any side.

I learnt a lot today. And I learnt more than I have learnt before. About the principle of how to light a bulb and electricity works. I also learnt about electricity is the movement of elections, elections must move in a continuous path (circuit) in order to light a bulb. I really enjoy learning in this way. #thelearningneverstops!

In the first science challenge I learned about friction. We tested with two note books and treiedn to make the two text book not move. I tried to put more then ten page together we but we did it quickly and it opened very quickly. My hypothesis was that if we( me and my partner)do it with one page it will be unbreakable because 10 page don't have that much fricition but with 1 page it will be enough friction.
I succeeded as what i hypothesised do it with one pages and it worked out really good and was unbreakable. My conclusion is that the fewer page there are the more friction there is and it is hards to break

Oh, a science challenge, what is the topic of today's science challege?

At first, Mr.Fisher introduced to us about the battery, the purpose of this science challenge, and the criteria of the science challenge. Basically, the science challenge is about electricity, it is very interesting, we only can use wire to light the light bulb with battery, we find each other a partner, get the materials and started to work!
At first, I think it is too easy for the grade 7 kids, and i think me and my partner will figure it out pretty fast, but unfortunatally, I was wrong, it is not easy, I think it is impossible to light the light bulb. I got realluy frustrated becasue of the challenge and some people are already done, I started to think I am so stupid, but after Mr.collin helped us and we succeed.

After, I started to try to put the light bulb on the negtive side, but it doesn't work, because there's not battery on the negtive side! I think the hypothesis statement is electricity is the movement of electrons, when I use wire to connect the battery to the light bulb, it makes it a electricity circle. And the another one is electrons must move in a continuos path(circiut) to light the light bulb.

In conclusion, I learned a lot about electricoty today, I learned if you pput the light bulb on the negtive side with only one battery, it won't work. I think the science challenges is really fujn, I'am enjoy it.

@Anita, I don't understand your PAR because I haven't learned it yet but I think it sounds pretty good! There are a few things I will point out though. You spelt really and electricity incorrectly in one two of your paragraphs so you might want to re-read your PAR before submitting. It's always good to double check. Also, you have many run-on sentences like the first body paragraph. It's made out of two sentences so I would try to change that. But overall good job!

I know this! Todays challenge is going to be easy peasy lemon squeezy.

Last week we had our first challenge on Newton's three laws. Our challenge was to stick two books together using ONLY friction. That's it, two books, and friction. Now how am I going to do that? When Mr. Hong first told us about this challenge I immediately got to work in my head. I pictured different possibilities and the outcomes but it didn't work out in my head. The first possibility I came up with was just breathing on the books to create condensation then simply slapping them together. Huh? Will that really work? Naw, probably not. It's also pretty gross. Now what, tuck the covers under each other? Wait, that's not friction... Or is it? Well even if it was then it isn't enough. So I need more tucking. Hmm... Wait MORE tucking! I remember this!

When we were told to get started me and my partner grabbed two text books and began to tuck ~0.5cm thick pages onto the other from the two books. It's a little bit hard to explain but you take the two books and you alternate tucking the pages on top of each other. When you're done combining pages you try to pull the two books apart without wedging it and if it doesn't come apart you have succeeded. I had a feeling that if we put the pages down one by one it would be impossible to pull apart without damaging the book.

I think that the more stacks of pages that you have the better. Why? Well, the more stacks the more friction there is. If you stacked the pages one by one then it would make more friction. Then that's where all the stuff I don't know about comes and blah, blah, blah.

So after this challenge I have come to a conclusion that the more stacks of pages the better. A short refresher behind it is that it causes more friction.

Today in scince we contued to learn how shock ing electricty and magnitizim is. for our first chalange we had to light a bulb using a battery, one wier. and one light bulb. I know what your thinking easy right? Wrong! a few of the groupes got it right away but most took some time to get it. This challenge was to show that electrons must travel ina contuis path

The first science challenge, we tried to put two books together in a way where they wouldn’t come apart even when we pulled on them. ( I’m not sure how to phrase it.) For the first try, we tried lapping over five pages together to see if it would work. It was actually quite strong but it wasn’t strong enough. My hypothesis is that with lapping five pages of the book didn’t have enough frictional force. The second try we succeeded, and for this trial, we lapped a lot more pages than before. This time it worked because it had a lot more frictional force which created a huge force that you cannot overcome. My conclusion is that the more frictional force and the weight there is, the two books will not come apart.

In third grade, we would always have silent reading. Since I hated this I would do basically anything but reading. I would usually just stare blankly at the book waiting for silent reading to be over, but one day I decided to play around with the books. So I got two dictionaries and decided to join them together. Now I’m not sure where I got the idea of doing this, but I ended up doing it.

So our science challenge was to link two textbooks together with friction. Since I already knew how to do this, there wasn't really trial and error. It was like trial and done, but for this par, I’m going to put myself in the view of someone who hasn't done this challenge before.

So when I was doing this challenge I first thought of casually putting the books together by sort of stacking them? (I don't know how to explain it) I soon realized that that was not very firm and could easily be pulled apart. I then came to a hypothesis statement of “if I alternate stacks of smaller pages there will be more friction, therefore, making the books firmer and harder to pull apart”. What I ended up doing was overlap the covers and alternated overlapping pages until both books were intertwined.

Conclusion:
My hypothesis was “if I alternate stacks of smaller pages there will be more friction, therefore, making the books firmer and harder to pull apart”. My results support my hypothesis. The experiment went how I planned and ran pretty smoothly.

How is electricity and magnetism work together? They are two things that seem different, but they have a lot in common. Electricity involves energy transferring from one place to another due to existence of charged poles. On the other hand, magnetism is when particular materials such as iron can produce forces.

Today in the class we did a challenge related to the topic that I have mentioned. With the use of the battery, we tried to connect the two wires with the same positive charges and attached it to the light bulb but was unsuccessful. In addition to that, we did the same thing but with the same negative charges but then again it failed. However, on our last attempt to connect the two wires with the opposite charge which is positive and negative then it was a success as evidence of the lighting bulb.

My hypotheses are: 1.) Similar charges are both negative or both positive. 2.) Opposite charges are connected, one is negative and the other is positive. The first hypothesis was unsuccessful on the other hand, the second one was a success.

Therefore I conclude, that changing the direction likewise changes the direction of the field. Like poles repel and opposite poles attract.

Let's puul again! And again! And again! and again. and again... That book is never going to separate. It is almost impossible to pull the books apart, b ut in the end, the book ripped, but didn't separate in one piece.

In the Gr.6 science experience, I tried different 2 different types of ways to help me keep the books together, and one failed. The first thing I tried was to rub the books together. I thought the static electricity will hold the books together, but it cane away as easy as air. So then I thought again. What if I put the pages together? I thought about that because when I slide my fingers along the table, it's harder to move than moving in mid-air. I also tried moving my hand on the table and with a book on it. It was harder to move because it had friction with the book and the table. So then I tried it with the textbooks. It worked. And I also found out that if more pages are together, the harder to move, and also that it is still possible to seplerate the books even if there is a lot of pages, but it will just me relly hard.

Overall, the challenge was fun and creative. It made me think of how friction could help you keep books together. My conclusion was that if you put the papers to gether, it will be really hard to pull out. And more pages that are put together, the harder to pull.

The very first challenges we received in this science unit is to light the bulb using the given material. (battery, electric wire, and light bulb) As soon as we got our materials, the first thing we tried out is to connect the top and bottom part of the wire with the light bulb touched. As we thought it didn’t work obviously since we’re only connecting it to the positive side. At the end of the first challenge, I’ve concluded that if we checked and make sure all our materials work and use it properly, then we be able to successfully light the bulb. We used our background knowledge to support us with while testing it. For instance, a battery must include a positive and negative side. We came to success after we figure out our battery is out of power.

In conclusion, I am coming to understand that we should always pay attention to our material since we wasted time on changing the light bulb instead of noticing that the problem is coming from our battery. I think this challenge is pretty fun, we could actually learn a lot in it and use it as background knowledge for the next challenge.

We started a new science inquiry project, and the first thing we did was watch a couple of videos that helped our mini class ( grade 6s ONLY ) and right after that we began a small inquiry, we were told to use ONLY Friction to make two school textbooks inseparable.

Trail #1
With my partner, we discussed ideas in relation to how the books can be made inseparable, and the first thing that can to both our minds was to use the pages of the book and somehow stick them together, therefore creating friction, so first we tried half of book #1s pages and stuck it with half of book #2s pages! Realty I did not succeed in any level!

Trail #2
The second very obvious thing to do if trial #1 failed! Use more pages, and that's exactly what we did so we did a quarter on a quarter of each book! Realty that was not some much successful in my eyes, but on the right track!

Trail #3
Well, this is the part that took, well let's say a more extension of time than before and I mean a lot, the idea was to create a huge amount of friction that would hopefully make the books inseparable and well that worked! I and my partner used every single page of both books and later the books were inseparable!

In conclusion to this mini-inquiry, I believe that the more friction that is applied, the more the objects will be compressed!

2/11/2019 08:31:27 pm

I did not learn anything because I learned about friction a lot of times. I succeeded because of friction. My conclusion was I think if I spray the pages with water a bit the it will stay together more. Or even better. But its good enough you can't take it apart because of friction.

PKM

2/11/2019 08:37:24 pm

One, two, three pull the books. The books would not separate. It was impossible to take a book apart with an another book.

In the the Gr.6 first science experience, we have to make friction with two textbooks. I was confused how to this. I tried one idea but sadly it didn’t work. My partner came to an idea and I understand what her idea was. The idea was put the two books together and put the pages on the books. It make friction. How many times you pull it, it would not broke or let’s go of each other. I found out less pages make more friction

In conclusion using more books would be strong because it has more friction.

2/11/2019 08:47:51 pm

Wow, a challenge! Maybe this science inquiry will actually be a lot simpler than I thought.

Well. That was a bad hypothesis. The first challenge that we actually did for science was a lot harder than I expected. We were expected to use only a light bulb, a wire, and a battery to make the light bulb light up. Oh, and a wire stripper in case we needed it.

First, our group tried doing a few wrong circuits including using only the bottom of the light bulb (which doesn't complete the circuit) and putting the light bulb in the middle of the wire (which needed two wires but we didn't know that.) However, when we did the actual the correct circuit, the light bulb only flickered a bit before going out.

Since we faced this problem, we kept changing the light bulbs, to no luck. We figured that maybe we accidentally did a circuit a while back and that we had to do it again. But then Ms. B told us that we were right and there was actually one thing we didn't think of... changing the battery! So once we changed the battery it worked perfectly.

In conclusion, we have to think about all parts of something, including the (almost) not-important things.

@Miranda this was a very good PAR but there were some things that you may have missed, feel free to disagree.

The Criteria of the PAR had stated that you needed to show a Hypothesis after you had failed the first idea.

Also the very first word of the first paragraph has a period, you can alter this to have a comma.

Over all amazing PAR, keep up the good work.

Around two weeks ago we had begun the next inquiry. For the grade sevens, this inquiry involved proving the relation between electricity, and magnetism. This will be done by going through different related challenges, such as creating a circuit. We had begun by watching some videos to kick-start our brain cells, and to start taking down some notes. There was a small period where we had no science, but right after we came back, the first challenge begun. This first challenge consisted of lighting a small bulb using only a battery, limited wire, a wire stripper, and a small light bulb.

I was working alone for an extra challenge, so there will be no we. The first thing I tried was holding the wires between the top and bottom using my hands, I realized that my hand was heating up because it was a small conductor. When I learned this I waited for my hand to get hot and then I stuck the light bulb on my skin, nothing happened. After that silly endeavor, I simply tried connecting the wire to both ends, after I placed the bulb on the top, nothing happened. I was talking to someone as I was doing it, and they managed to light the bulb, and they gave me a small hint, after I began to hypothesize. "If I connected the wire to the metal side of the light bulb, then it would finish a proper circuit.

I had tested this hypothesis and low behold it worked. I had tested doing different connections, such as connecting the wire to the bottom of the bulb, then placing the side of the bulb (The conductor) on the battery, which also worked. Later me and a friend made another hypothesis "If we place three batteries onto each other, then connect he bulb and wire, the light would get brighter. We had tested this and the limit was six batteries, any more and the battery would instantaneously burn out. The light was also blinding so writing was quite difficult for some time.

In conclusion, a complete circuit requires the moving electrons to be moving on a perpetual path, and that the more electron included into the circuit, the more power something will receive.

@ Unaid - Great job! I liked how detailed you were and how you gave examples to support your idea. Though, your writing can still be improved. First, you cannot link two sentences with just a comma. You need a conjunction, but for sentence two in paragraph two, that would become a run-on. This leaves you the only choice to replace the comma with a period. Also, see if you can find other run-on sentences. Other than that, great job!

A few days before, we were doing science. The units we were doing are electricity and magnetism, and we do our first Science Challenge for that. We were required to light a light bulb using a wire, a battery, and a small tiny light bulb to light. But before that, Mr.Fisher introduced to us about electricity and magnetism. Also the purpose of this science challenge, and the criteria for the science challenge. When heard about it I thought that this challenge will be very easy for me, I thought I can do it within a few minutes since I have the main idea of how it works. However, I realize I was wrong about the idea of it was too easy. I know it should work because the wire was hot but then the light bulb just won’t light up. I keep on trying to connect them in different ways, and there is one time when I think back what I try to light it up I think I was really out of my mind. I to connect the light bulb in the middle of the wire. But thank god nothing happens. Anyway, I am so excited when I finally succeed. One of the hypothesis statement I think can work but did not is. You can connect as many batteries as you want, it just that you have to connect both sides correctly. But that hypothesis statement didn’t last long after Mr.Fisher said that the other group does an experience using five batteries and the light bulb just burn up.

Our challenge: Get 2 books/textbooks INSEPERABLE using Newton's 3 laws of force and motion.

Attempt #1: My partner and I used the first obvious thing that came to our mind: to put the pages of the textbooks on top of each other. Basically, we just put a few pages inside of the other pages of the other textbook. That kind of worked, but then when we tried to pull even harder, the textbooks separated.

Attempt #2: So, seeing that the first attempt kind of worked, we decided to do the same thing, except we put less pages on each other. That ALMOST worked, but it didn't. We pulled really really hard, and the textbooks were once again separated.

Attempt #3: We knew we were on the right track, so we did the same thing, except we put even LESS pages on top of each other. Actually, it was one page on top of another page, on top of another page, on top of another page....you get the idea. We did that until we put all the pages on top of each other. It worked!

I really didn't think it was possible to get 2 textbooks inseparable just using friction. To be honest though, I have no idea how that even works. Like....mind-blowing

Zap! That's how the heat hit my fingers when we did actually make the lightbulb light up.

At first, we tried taking both need of the wire and pressing them both against the + side of the battery with the light bulb touching it. We had no idea that that we needed to create a circuit between the bulb and the battery with the wire. My hypothesis afterwards was that I probably needed to use the wire on both ends of the battery, maybe try out different bulbs or something like that. Little did we know, while my partner was trying something out, she tried out the method that we thought of. The one with creating a circuit by taking both ends of the wire and using both sides of the battery. I wasn't watching when my partner had succeeded but I saw it when she did it again.

My conclusion is that in order for you to make the light bulb like up with just a battery and one piece of wire, you have to create a circuit between the light bulb and the battery using the wire.

At first, we thought it was easy, but it turns out to be quite challenging! Last week, we (as in the grade 7’s) started our new science unit about electricity and magnetism. We are going to doing an inquiry. Unlike our previous inquiry, we will be doing experimental inquiry, not research-based. We started our first challenge, and we were required to light a lightbulb with wire and a battery.

I tried many different ideas before I finally lit the lightbulb. I put the wire on the negative and positive terminal with the lightbulb on the middle of the wire. I also tried putting the lightbulb at the end of the wire. Then after that try, I remembered our lesson mentioning about circuits and a loop. Consequently, I thought that if I made sure the power went through a circle back to battery, it would finally power the lightbulb. I tried that by putting the battery on the positive terminal itself and having the wire connect to just the side of the lightbulb’s base. That worked, so I concluded that in order to power something, you need to have a circuit. You need a current (flow of electrons) that goes out of the power source and back in.

In conclusion, this is what I did for my first challenge of the electricity and magnetism unit. I learnt a lot of things, but I still do have questions. I hope that I will be able to answer all my questions in the following challenges!

On Monday, we did a continuation from last weeks lesson. This time we had to see if we could make hypothesis, using the same materials we had last time.

First, my partner and I tried and made two light bulbs light up. We both tried continuously, and it almost worked. Since we didn’t have enough time, we were not successful. That was one thing that didn’t work for us at all. After that we tried what many others tried after. Putting 4 batteries together and lighting one light bulb. It worked of course since many others already tried it. We tried 5, but it did burn the light bulb out. We could only burn out one, so we couldn’t try anymore batteries. That was very successful on our part.

My conclusion on my part, I would think I know how to successfully light a bulb with no help needed. I know how energy works, and I’m getting better and better at it. :)

At first when Mr. Hong had told us about our challenge which was to attach two text books together so they are impossible to pull apart. using nothing but our creativity and the two text books. at first i thought Mr. Hong told us that it would be "impossible" in my head i thought he meant that very hard or impossible for kids. but Mr. Hong was right. we even saw a video of a machine trying to take the the two overlapping books apart. but the machine was not successful, the books just ended up ripping. that is because of FORCE!!!
their was so much friction between the two books that they would not come apart first my partner Ariel and I overlapped five pages but were not successful. the reason is because their was not enough friction between the page. Next, we tried overlapping 63 times! and we were successful! this was because their was lots of friction between the pages.
A question i still have is would this work on a different planet?
Does gravity have to do with this experiment?
If sientiests find out how to take apart these two books without harming them. Would that solve any of the big problems around the world?

in conclusion it was really fun doing the experiment and gave me a much better understanding of how friction works!
