As we wrap up Unit A, "Studying People Scientifically", I thought it would be interesting for us to investigate a new product on the market for consumers. Have you heard about Power Balance Bands? According to the Power Balance website, their product gives you energy, power, and gives you better balance for about $60.00. Is this a new and exciting scientific breakthrough or is this product a scam? So the real question is do these bands really work or is this a hoax? Lets check out the claims and watch the videos and let the evidence help us make some informed decisions about this products claims.
Check out the link below from Power Balance's own website.
Video One
Video two
Respond to both A and B by Tuesday 10/5
A) Based on your observations, what are your thoughts on the effectiveness of the Power Balance Bands? Give 3 pieces of evidence to support your ideas.

- What was the hypothesis (if and Then)
- What was the control?
- What was the IV
- What was the DV
- Do you think this was a controlled experiment? Provide evidence to support your answer.
C) Why is it important to test products scientifically before making them available to the public?

My observations are that they dont work because it would be better if they did it live, they could also be lying and they could be moving when they put there bands on.
The hypothesis is: If you aren't strong normally and you buy a powere band then you will be more stronger.
The control is not wearing the power band.
The IV is naturally being weak.
The DV is wearing the power band.
I think it is controlled because its not live and it doesnt show the full body view.
If the product doesn't work then people will want their money back and the bands will go out of buisness.
A.) I believe that the power balance bands work because they tested the balance, strength and flexibility without the band then with it and everything improved.
B.)If the power balance band is on then your strength, balance and flexibility is better. The control was not having the power balance band on. The IV was the power balance band. The DV was your performance. I think this was a controlled expeirement because they tested the products two ways.
C.) To make sure that it works and it's not a scam for people's money.
A. I think that the Power Balence
Bands work. Shaq said they work and gave an example of his team winning by 57 points while 3 players, including himself, were wearing the band. The test of the bands showed a man flexing farther than he could without the band when he put it on. The other test showed the man balencing really well with the band than without it.
B. The hypothesis was: If the power band is on your wrist, then you will become stronger, more flexibale, and have more balence. The control was not having the power band on. The IV was the power band. The DV was your performance. I think this was a controlled experiment because there was a control group and experiment group. One group got a regular band and the other group got the power band.
C. It is important to test products scientifically so that people don't get a bad product or scammed.
A.) I think it's real and that it works because it sells for 60 dollars and I don't think people would sell it if it didn't work. Also, I saw a number of different tests that proved that it worked. Another reason is that Shaquille O'Neal said it worked and I don't think he'd lie for t.v. because he is rich and doesn't need money.
B.) If people wear this bracelet then they will ba able to balance more, focus better, and be more flexable. The control is a person that didn't have the bracelet on. The I.V. is the people that didn't have the power balance. The D.V. is the no change in energy.
C.) It is important to test something scientifically because if you sold it to the public and it didn't work then they might want their money back or won't buy anymore of your products.
A) My opinion about the effectiveness is that they do not really work because of the australian video and the card test, and when they were blind folded they one with the bracelet didnt have an any thing change.
B)Hypothesis: If you wear the braclets, then you will have more energy and endurance.
Control: the placebo and the real bands
IV:tHE Bands
DV: No change in energy
I think it was a controlled experiment because you had the people (the control)
C) Testing products scientifically is important because if you couldn't test then we would not know how the products work.
A) Based on what I've seen about the Power bracelets, I believe that it pretty much works, but has an extreme placebo affect of people which can be misleading. When they tested this on people when the people know that they have the true product there brains meke them think that it works, then it shows it does. And when the testers didn't know who had the product, they could not tell who had it after the tests. Also I believe this works because Shaq would not just promote something like this, without truly believing it.

A.I don't think it works, but it looks cool. One example is that the one scientist said its just like a placebo and mental. A second reason is that when he didn't know who had the band he picked a different person who didn't have it. Though when he knew he picked the right person as if they seemed stronger. This just proves its all mental with these things.
B. If you have the band an you know it then you will be stronger, but if you don't know then you will be the same. The control would be the people without then band. The IV would be the bracelet. The DV would be the change of strenght and balance in you.It was a controlled expieremnt because they compared people with bands and people without bands.
C. Its important to test things before selling them so you know if they will work and if they might get hurt or have side effects from it.
A.I think the power balance is a scam because i think if you think it will help you it will, if you think it won't it won't help you. I think this because when they did the test and the person didn't know he had the power balance his balance wasn't better than anyone elses test. The strength also didn't change. The persons flexibility didn't change either.
B.The hypothesis is if the person is wearing the power balance, then their balance, strength, flexibility. The control was the regualar braclet or the regular card. The IV was the blind test. The DV the power balance that increases balance, strength, and flexibility.
C.To see if they work, and if there are safe for people.
A) I think it is a scam and that the person is thinking they are stronger and more balance. So basically I mean is the placebo effect. They are taking people’s money and it is not fair.
B) If people think it works then they will buy it. The control was the bracelet. The IV is the people not being strong .The DV is the when the people didn’t know and it didn’t work. Yes this was a controlled experiment because they did different tests
C)so we are not scammed by people and waste money.
I believe it is a scam. I believe it because the power of the mind will believe in it enough to show improvment even if it is a scam. My second reason is for believing this is; the man who created the Power Balance did NOT know his own product. And when they had the blind test the people who did not have the band did not do well as well as the person who had the card. If you wear the Power Band then you should improve in balance, strength, and flexibility. the control is the power band. the iv is the blind test, and the dv is the effects that the power band is suposto improve. yes because they test them one at a time
A.) I think this product was effective because there sample size seemed large enough and there tests seemed effective testing there performance, flexibility, and balance.
B.)
1. If you wear the Power Balance Bands then it will give you better energy, power, and balance.
2. The control of this experiment was the regular Power Balance Bands.
3. The independent variable of this experiment was the Power Balance Band.
4. The dependent variable of this experiment was how much power, energy and balance improved.
5. I think this was a controlled experiment because they test one variable at a time.
C.) It's important to test products scientifically before making them available to the public because people want to know if it actully works before buying the product.
A powerbands are a scam in my mind based of the fact that the owner of the power band company couldnt even tell the difrence between blindfolded people who didnt know if they had it. another thing is people who knew they had it put mind over matter because in there mind they thought somthing spaciel was happing, the last reason is there is no outstanding data to prove against me.
B the hypothises was if you were a power band then you will have more energy, power and balance.
the iv was tthe powerband, the dv was your preformence. the controll was the group with out the power bands
C it is importent to run test so people know exacutly what they want based on all of the information givin so they wont have people wanting money back
A.) I believe that they do work. I feel this way because if they didnt work I dont think a lot of people would buy them for $60 and I know people do. I also saw a nember of tests that roved the bands work. My last reason is that Shaq said that he uses it and it works and I dont think he would lie about that because he doesnt need to get paid anymore money, he's already rich.
B.) If you apply the Power Balance on to your body then you will become stronger and have more balance than you will without the band.
The control is someone not wearing the Power Balance Band.
The IV is the Power Blanace band.
The DV is your preformance while wearing the band.
I think this was a controlled expeirement because they tested the product two different eays and they did it one at a time.
C.) It is important to have the bands tested scientificaly before they are able to be sold because they should have to prove that the product works and its not a scam so people wont waste their money.

A. I Don’t think it works because peoples’ minds are just playing tricks on them. If u tell someone it works and then they will think it works. Also from the video we watched the man who invented it couldn’t even tell who had it in the exsperiment.
B. 1. If u wear a power balance bracelets then u will have more energy better flexibility and strength.
2. the people that didn’t have the power band
3.the power band
4. better preference
5. Yes because some people didn’t have he power band
C. Its important to test products first because they might not work. They might break easily without the product people knowing. There could be something in the Product the could form reactions.
A: I believe that it is a scam because when they tested it and people didn’t know they had it on they didn’t see a difference. When they knew that they had it on though they thought it really worked. Two other people tested it to and they said it worked because they tested it with it on and off and it made a difference but really they were just receiving a placebo effect.
B: In the 2nd video the hypothesis is if the people are more flexible, strong, and balanced then the power band works. The independent variable is the power band and the dependent variable is the strength, flexibility and the balance. Yes, it was a controlled experiment because it has a hypothesis and a good procedure and a placebo and real medicine group and it has a good sample size.
C: It is important because you need to know that it works and if it has any signafects.

A.
I believe that the Power Bands do not work. I think that it is just the placebo effect. People wear them and believe it makes them stronger because it says so. In the Video number two the creator kept picking the people who didn’t have the Power Bands bracelet/card. Also anybody could make up the results, so watching a video isn’t really a resource but testing it yourself would work better.
B.
1. If you wear the Power band then you will perform better.
2. The controls were the people who don’t have the Power Bands on.
3. The Power Band was the IV.
4. Better performance was the DV.
5. Yes I think this was a controlled experiment because it had a good hypothesis and a reproducible experiment.
C.
If they don’t work then people will quit buying them and they will slow down on production and the product will not make any money.
A.) I believe the Power Balance Bands do not work. One piece of evidence is that when they did the blind fold test it did not work. Another piece of evidence is that it only worked when people knew they had it on. The last piece of evidence is that no one can prove it works.
B.) The hypothesis is if you are wearing the power band, then you will get more flexibilty and strength. The control is the people not wearing the power bands. The IV is the power band. The DV is the effectiveness of the band. This is a controlled experiment because they only have one variable.
C.) It is important because the tests can show if the thing you are testing works and is not a scam.
A) My thoughts and effectiveness of the power band are that it is false advertisement and a lie because it tells you you get 5 times the strength balance but when they did the tests their balance barely changed and they looked as if they are trying to sell you something that should truly be about 5 dollars and instead is 60 dollars.
1. if you wear the power band then you will get 5 times stronger.
2. the control was the poeple being tested.
3. the IV is the power band.
4. the DV is 5 times srength
5. I think the product was controlled because they showed many ways of how the product could help you and how it "works".
C) It is important to test products scientifically to see if it is helping or if it's just a lie.
A) Based on your observations, what are your thoughts on the effectiveness of the Power Balance Bands? Give 3 pieces of evidence to support your ideas.
I think that they work because:
1. In the Third video it showed the person pushing down on the person that had the band and it did looked like it was working.
2. Even if It didn’t work they could tell people it works through the placebo effect.
3. If it dose not work itself but they tell you it dose then it will work if you think it will.
B) After watching video two, answer the following questions about how the power balance bands were tested.
What was the hypothesis (if and Then)?
If you put this band on then you will be stronger, more flexible and balanced
What was the control?
The people that didn’t get the real card
What was the IV?
The band
What was the DV?
The people
Do you think this was a controlled experiment? Provide evidence to support your answer.
Yes because they had a control in it which was the people that didn’t get the card with the thing in it.
C) Why is it important to test products scientifically before making them available to the public?
To make sure that your paying hard earned money on something that works
A) My opinion about the effectiveness is that they do not really work because of the video and the card test when they were blind folded the one with the bracelet didnt have any thing change.
B)The hypothesis is If you wear the braclets, then you will have more energy and flexibility.
The control is the placebo and the real bands
IV:the Bands
DV: wearing the power band
I think it is controlled because its not live and it doesnt show the full body view.
C) Testing products scientifically is important because if you couldn't test then we would not know how the products work.
