try testing serving ways....try at least 10 people and that should help!
Here is a good question: "How does the angle of your arm in a spike affect how fast and powerful your spike is?"
You can write how the speed and velocity of hitting a volleyball affects where it bounces.
some science questions about volleyball could be how much energy do we need to hit the ball
A good science project for a 6th grader would be about magntism, like does the bigger the magnet mean the gravitational pull will increase if you try to pick up bigger things than that.
i think best science project would be YOUR idea.
For good ideas, i would suggest to browse the net for sites with such content. I have provided a link in the related links. It is from a e-newsletter subscribed to www.about.com.
water cycle
i think i know
You would bring your project.
i have him for my science project in 6th grade.
Sure would.
I would do a project about disposable diapers in landfills and how long it takes for them to biodegrade.
my answer would be a gauss rifle
Something about bacteria.
A good last minute science fair project for a 7th grader would be to make a volcano. Use vinegar and baking soda to put in the crater. This will bubble up and make it look like lava and smoke is coming out of the volcano.
