The student conducted an experiment to test whether rubbing a balloon more times would make it stick to a wall for longer. They rubbed a balloon 1 additional time over 4 trials, recording whether it stuck and how long it stayed. Most trials showed the balloon staying longer with more rubs, but sometimes it did not. The student learned static electricity is generated through rubbing, causing balloons to stick, and more rubs should mean more electrons and a longer duration on the wall.

2. My Hypothesis is: I don’t think
it will matter how many times
you rub the balloon.

3. First I got a balloon. I
started by rubbing it on the carpet
1 time. Then put it on the wall to
see if it would stick. If it stuck I
timed it to see how long.
I did the same thing 4 times.
Each time I rubbed the balloon 1
more time than the last.
I did this whole experiment 3
times, so I could compare the
results.

4. TRIAL # OF RUBS DID IT STAY TIME ON WALL
1 1 YES 2 MIN 21 SEC
2 2 YES 5 MIN
3 3 YES 1 MIN 45 SEC
4 4 YES 3 MIN 25 SEC
TRIAL # OF RUBS DID IT STAY TIME ON WALL
1 1 NO 0
2 2 NO 0
3 3 YES 1 MIN 23 SEC
4 4 YES 1 MIN 27 SEC
TRIAL # OF RUBS DID IT STAY TIME ON WALL
1 1 YES 2 MIN 12 SEC
2 2 YES 3 MIN 5 SEC
3 3 YES 15 MIN 50 SEC
4 4 YES 4 MIN 19 SEC

6. My guess was not really right
or wrong. Most of the time the
more you rubbed it the longer
it would stay. But there were a
couple of times that were
different.

7. I read this book on static
electricity. I learned that
everything that turns on has
electricity. Some electricity can
be dangerous, like lightning. I
learned that rubbing a balloon
picks up electrons and when
they run out the balloon falls
off the wall. The more times
you rub it the more electrons it
picks up, so it should stay on
the wall longer.
