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.

A) We think that the Power Balance Bands are effective because they improved our athletic performance, flexibility, and balance.
B) 1. If you wear the Power Balance Band then your flexibility, strength, balance, and endurance.
B) 2. The control was the regular cards and bands.
B) 3. The IV was the power balance band.
B) 4. The DV was how much your flexibility, balance, strength, and endurance improved.
B) 5. No because they only tested it on a small sample size.
C) It is important to test products scientifically because people will want to know if it actually works and is effective before they spend that much money on it.

A) We think it is a fake. It is the placebo affect. When people know that they have the bracelet then their mind is telling them that its going to work so it does. When the tester knew when the people had the bracelet it worked but when he didn't know it didn't work.
B) The hypothesis was if you wear the power bracelet then you will have more power, strength and flexible. The control is people without the bracelet. The independent variable was the bracelet. The dependant variable is the power change. I think this was a controlled experiment because they had a control and experiments. They also had a large sample size.
C) It is important becuase if it is not safe to the public then you can't make it available. That's why ypu need to make sure you test it before you make it available.
A)We think it does not work. we think that it is just your mind thinking you get more power instead of having more power. just like the placebo when they gave the people who had the placebo had not gotten the real medicen they got the placebo they still thought they felt better.
B)1.If you were wearing the bands then you are not suposed to fall over when someone pulls on you.
2.The people who did not wear the bands.
3.The IV would be if you buy them it gives you power.
4.The DV would be if you wear them you have more power and increased balance.
5.It was a controled experiment because they had people wearing them and not wearing them and the people with no power band fell when someone pulled on them.
C)It is importent because if someone bought it and it did not work then they would tell other people then it would not sell.

a[ It doesnt work because when the tester didnt know where the braclet was it didnt work, but when the people saw the braclet it worked so it was just in there minds that it works.
b[ 1.The hypothesis is if you wear the braclet it will give you beter balance.
2.The other people that got fake cards.
3. The power balance band.
4.if it worked on your or gave you beter balance.
5.yes it was an controlled experiment because they had a control and a placebo to compare results to.
6.they need to test if it is harmfull or not.
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[ It doesnt work because when the tester didnt know where the braclet was it didnt work, but when the people saw the braclet it worked so it was just in there minds that it works.
b[ 1.The hypothesis is if you wear the braclet it will give you beter balance.
2.The other people that got fake cards.
3. The power balance band.
4.if it worked on your or gave you beter balance.
5.yes it was an controlled experiment because they had a control and a placebo to compare results to.
6.they need to test if it is harmfull or not.
A)We think that the power balance bracelet is fake. To prove our hypothesis we have evidence to prove that its fake.One reason is in the video we watched they guy couldnt guess which person had the bracelet except when we saw the person holding it.He didnt know which one had the credit card.The weak people always had the bracelet.B)If someone wore the braclet then they got powers. The control was the braclet. The ID was the braclet. The DV was the people.Yes,they did it with and without people wearng the bracelet.
C) It important to test it because if they didnt people wouldnt buy it.

A1.) I think the Power Balance Bands are effective because when the poeple got tested they passed it.
A2.) I also think that the Power Balance Bands are ineffective because when the people tested to see if the hologram caused it & they found that it didn't.
A3.) I also think that it makes people stronger when they know that they have the hologram, but when they know that they might not have they are nor stronger or have more energy.
B.) The hypothesis is that if the Power Balance Band works then the person wearing it will get stronger and have more balance. The control is the Power Balance Band. The indepedent variable is would be the Power Balance Band. The dependant variable is the people who wear the Power Balance Band.
A}We think that power bands are effective because they gave the people more strength,flexibility, and energy.
B}1.If the power bands do not work then they are a rip off.
2.The control was the people without the bands.
3.The IV was the power band.
4.The DV was how much the power band worked.
5.No because the sample size was not that big.
C}It is important so you know the product is safe and so that you don't waste alot of money making the product.

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.
We think it was the placebo affect. We think this because when they didn't know if they had the real power band or not, they didnt feel stronger, more flexable or balanced. So we think it was more of a mental strength and it wasn't the band that made them feel this way.
B) 1. If the bands work then you would feel more balanced and stronger.
2.The control is the credit cards, and fake bands.
3.What was the IV
The Power Band is the IV.
4.What was the DV
The DV is that people felt stronger and more balenced.
5. Yes, because at the end they tested the power bands more pricisily by not telling the people if the had the real band or the fake band.
C) It is important because if you sell something on the market and you say it will work. The prduct would have to work.

A. I dont think the power bands work. I think this because in the video when they were going up to the six people and gave them the card and the person who had the card didnt have balence but the person who didnt had balence. I think when they get the power band it is all in their head that it is. I also think it matters how tall and what you weigh.
2B. If the power band worked then you would be faster and stroger.
2C.The iv is that the power band help your balence.
2D. The dv is that they dont make you stronger.
2E. Yes because they did it with other card and tested their balence.
C1.To see if it really does work.
A)
My thoughts on the power balance band is that it works. 1st is that man people with lots of money are enforcing it when they don't need any more money. 2nd they have great evidence of the power balance band working. 3rd is that me myself tested the power balance band and it worked for.
B)
If the person wore the pb band then they would be more flexible.
