**Teacher Comment: Dylan you have conducted a very fair test that anyone could take away and do themselves based on your method. It is awesome to see that you have found the averages of your results - great for presenting it :) You have a eye capturing title which is great to see and it is fantastic that you have incorporated the science behind your results as this gives you a better understanding of what is happening.**

**Student Comment:**

Introduction:I am doing this science project because I have always wondered, why your hair stands up when you rub it with a ballon.

Aim:Is to see how long your hair stays up, by rubbing it with a ballon for different amounts of time.

Materials:
 * 1 balloon
 * 1 stopwatch
 * pencil
 * paper
 * head of hair

Hypothesis:My hypothesis is that the more you rub the ballon on your head, the longer your hair will stay up. Because the more you rub the ballon on your hair the more static electricity you produce.

Method:
 * 1) Blow up 1 balloon and tie off the end.
 * 2) Rub the balloon once on your hair back and forth. Hold the balloon up above your hair, at the same time start the stop watch.
 * 3) Then wait for all your hair to fall down, stop the stopwatch.
 * 4) Record the time in a table/science book.
 * 5) Repeat step 2, 3 and 4, four more times, increasing the number of rubs each time

Conclusion: I found out the more you rub the ballon on your hair, the longer you hair will stand up. My Hypothesis was correct. My results confirm this, by showing that if you rub the ballon on your head once, it only stood up on average for 48 seconds, where if you rubbed it five times it stood up on average for 3:15 minutes.

Why does your hair stand up when you rub a ballon on it?

You can find static electricity by rubbing your head on anything that can produce static electricity like a ballon,hair,wool jumper

Some insulating materials become charged when rubbed together. This happens because electrons ( which is a negative charge ) from one material, are transferred to the other material. The charge cannot flow away because there is no conductor( passing of heat or eletricity) so it builds up on the surface of material. So rubbing causes the already present electrons to move from one object to the other. They cling together because their opposite charges attract each other.

Electrical charge that is held by a material is called STATIC ELECTRICITY.

Application: You can find static electricity around your home. A trampoline is a good place to find it. If you jump long enough your hair will start to stand up. Sometimes when you hop out of your car you may find you have a bit of static electricity build up, or when you pull your polar- fleece over your head, you may here a crackling sound that is static electricity.

The water just fell out, then when we done it agin and this time we hold the cardboard on longer so it would not fall of so easy then i flip the glass over and took my hand of and it stayed. <span style="font: normal normal normal 12px/normal Helvetica; letter-spacing: 0px; margin: 0px;">Reflection: i had fun doing this experiment i think it was the best experiment of them all

<span style="font: normal normal normal 12px/normal Helvetica; letter-spacing: 0px; margin: 0px;">i cut out a circle and then coloured it in with bright colours. Then we spin it, the multiple colors on the spinner was hard to see because when you spin it is hard focuses on the colors cause it is going to fast to see them when i look at i reflection i had fun doing
