MONDAY: Pros and Cons of Electricity

6/2/2014

The students participated in a very active research activity today. They looked into the pros and cons of 7 different forms of electricity generation. The researched reliable sources for all different types (Hydro, nuclear, fossil fuels, tidal, geothermal, wind, and solar.) It gave the class a good idea of the positive and negative things that are associated with producing electricity and to always look at everything with a critical eye! (To be updated)

1.) WRITE A RESPONSE/MATH:

In an organized manner, be sure to include all the information below. Post questions here if you have any.
Perform an experiment like the red/yellow chip experiment.
Perform 10 trials for your experiment.
Record the outcome for each trial.
Record the ratio and percentage of each outcome to the total number of trials. For example, if you are flipping a coin for heads and tails and it lands on tails 3 times out of the total 10 flips, your ratio would be 3:10 and your experimental percentage for landing on tails would be 30%. You would also do the reverse for the number of times it lands on heads.
The theoretical probability that it would land on heads and tails would be 50%. State your theoretical probability (this depends on the number of outcomes - IE A die would have 6 outcomes)
What was your experimental probability for each of your outcomes?
Was your experimental probability be close to your theoretical probability? Why or why not?
What could you do to make your experimental probability be closer to your theoretical probability?

One out come would be seven out of three or 70 and 30%. Next is 50% each way.

You should re-read the post criteria and then re-write your post since you are lacking alot of the posts criteria.

Maybe you could make it a little clearer. Also put down something that shows how many times it was flipped or whatever you did.

Quarter flip experiment:
I flip a quarter 10 times, in those ten times I got 6 heads, and 4 tails. 6 heads would be 60% or 6:10, 4 tails would be 40% or 4:10. Theoretically flipping the coin would be 50 50 for both heads and tails. (I don't really think you can flip a coin and always get heads or always tails, so really there is nothing you can do to improve the ratio more one sided)

Theoretically flipping the coin would be 50 50 for both heads and tails. I could increase the chances of my flipping the coin and getting 50 50, I would simply just flip the coin more times to increase my chances of getting closer to my prediction.

Coin Flipping Experement:
I flipped my coin 10 times and 5 of them were heads witch is 5:10 or 50%. Also 5 of the times were tails witch is 5:10 or 50%. Witch theoretically Is 50 50 because it both half of 10.

Maybe add in a list of how they flip. For example on my first flip I got heads, ect. Good job over all though!

Coin Flipping Experiment:

I flipped my coin 10 time and got 5 of them heads and 5 tails witch both are 50% or 5:10 but it I got something like Sam and have 6 heads and 4 tails theoretically you could get closer to 50 50 by flipping the coin more times.

Flipping a dime

Theoretically speaking, half of the time it should be on heads and the same for tails. (%50 and %50) When I flipped the dime, it landed on heads %70 or 7:10 of the time and %30 or 3:10 for tails. You cannot make it more closer to the theoretical probability because it is a coin, it is just random.

Icestone

Flipping a dice with numbers 1, 2, 3, 4 and 5 on it, 2 repeated twice.

Theoretically, every number except 2 will have a 16.5% chance of landing on it, or 1 out of 6. The number 2, since it is repeated twice, will have a theoretical chance of 33.33% chance, or 2 out of 6, (2 sides have the number 2, 6 sides) or 1 out of 3. I actually made this dice, and I found that 40% of the time it was 1, 10% of the time it was 2, 10% of the time was 3, 10% of the time it was 4 and 30% of the time it was 5. Or, in fraction/ratio form, it was 4;10 or 4/10, 1:10 or 1/10, 1:10 or 1/10, 1:10 or 1/10 and 3:10 or 3/10. To make these recordings more reliable, I could do this experiment lots more times. My experimental probability was not close to my theoretical probability because sometimes, when you try some type of experiment only a few times it is very random and not quite accurate.

Flipping a Coin

It had a 50% chance to land On heads or tails
H= heads T= tails
1 T
2 H
3 T
4 H
5 T
6 H
7 H
8 H
9 T
10 H
4:10-tails-40%
6:10-heads 60%
It was very close to what I thought it would be
Even though I have no need to re-do it if I did to change to try to get perfect 50-50 half the time I could put heads up and the other half I could put tails up

Flipping a Penny

Flipping a penny has a 50% chance of landing on heads or tails. It has two different outcomes because there are only two sides on the penny.

1. Tails
2. Heads
3. Tails
4. Tails
5. Heads
6. Tails
7. Heads
8. Tails
9. Tails
10. Heads

6 out of the ten coin flips landed on tails. Percentage: 60% Ratio: 6:10
4 out of the ten coin flips landed on heads. Percentage: 40% Ratio: 4:10

My theoretical probability was close to what I thought it was going to be because it landed on tails six times and heads four times and my theoretical probability was 50%.

Judy Moody

Flipping a coin has a 50% chance of landing on either heads or tails.

1. Heads
2.Tails
3.Tails
4 . Heads
5. Heads
6. Heads
7. Tails
8. Heads
9. Heads
10.Tails

Heads: It landed on heads 6/10 times, so that's 60% and 6:10 as ratios and percents.

Tails: It landed on tails 4/10 times, which equals 40% and 4:10 as a percent and ratio.

My theoretical probability was pretty close, because it was 60% for heads! and 40% for tails. There are only two outcomes for a coin, so the probability of landing on heads or tails, is 1/2 or 50%. 60% and 40% are both 10% away from 50% so I think it was close.

Pancake

How can you get a better chance of getting 50% 50%?

https://docs.google.com/spreadsheets/d/1mOwcXmSn5X_-CpDqZIbrogtenEJIdHUqKCAhGGzFVnE/edit#gid=0
As you can see the outcome was 50/50 so, both ratios are 5:10, and both are 50%

Picking Cards:
I got a queen, ace, and king out of a deck of cards. I mixed them and picked a card, I repeated 10 times. There is a 3.33 chance of getting each card, the list went
Queen
Queen
Ace
Queen
Ace
King
Ace
Ace
King
Queen
I ended up with 4 aces, 4 queens, and 3 kings. So in the end I was one more king and one less queen away from exactly 3.33%.

Queens: 4:10/40%, Aces: 4:10/40%, Kings: 2:10/20%. So my theoretical probability was only a few cards of, so an a bigger scale, it would most likely end up being 33.33%.

Can you think of any other way of getting them all to 33.3%? It involves other people experimenting.

9)heads
10)heads

I had 6 heads and 4 tails the ratio for heads is 6:10 and the ratio for tails is 4:10. The percentage for heads is 60% and the percentage for tails is 40%.
I think it was pretty close because the I got 60 and 40 which are very close to 50.

1. Tails
2. Tails
3. Heads
4. Tails
5. Tails
6. Heads
7. Heads
8. Heads
9. Tails
10. Tails
So 60% of the time it was tails and 40% of the time it was heads.
The ratio would be 4:6

I rolled a dice ten times. 2 out of the ten times the dice landed on three.

2:10 = 20:100= 20%. Three was rolled 20% of the time.

@Cloud Barston
You have to go over the criteria again because you were supposed to make the ratio 6:10 for tails and 4:10 for heads. So it was a part to whole ratio and not part to part.

On a bigger scale because you can get more of an average that way.

@ATV BOY,
I know it was quite a dumb question for me to ask even though I knew you knew that. (Because JJ is just sooo intelligent) But you did not have that on your post so I had to ask.

Oracle

6/4/2014 02:46:22 am

@ATV, I liked how... you flipped your phone. I don't really understand why you'd do that because you might break your phone but, yeah.

Data collected on flips:
1. Tails
2. Heads
3. Tails
4. Heads
5. Tails
6. Tails
7. Heads
8. Tails
9. Heads
10. Tails
My ratio for heads was 4:10 (40%) and my ratio for tails was 6:10 (60%). The probably of getting heads or tails is 50%. So that would mean my ratios were close to its theoreticle probability because there were only 2 choices.

1. Back
2. Back
3. Front
4. Front
5. Back
6. Back
7. Front
8. Back
9. Back
10. Front
My ratio for the front was 4:10, so that would be a 40% chance.
My ratio for the back was 6:10, which would be a 60% chance.
The probability was 50%, or 1/2.
Same as last time, my flips were very close to my Probability.

Bobby Orr

6/4/2014 12:51:47 am

Maybe having to cards and then shuffling them and get someone or your self to pick a card. And repeat this process for 10 time and the write down the ratio. Example. 5 ace:5 king . That would be 50%.

Bobby Orr

6/4/2014 02:17:03 am

Juliette

6/4/2014 02:30:18 am

I flipped a coin ten times and then made a ratio of how many times the coin was heads and how many times the coin was tails.
The ratio and percentages I got from doing my experiment was 7:3, 3:7 and 30%, 70%.
Theoretically it should be a 50/50 chance but experimentally it is a 70/30 chance unless you have more trials.

ATV BOY

6/4/2014 02:42:30 am

Maybe you can record what happen each time when you flipped the coin.

SAM

6/4/2014 02:45:52 am
