Hi Kaitlin,

For us to give you a more certain answer we would need more details of your procedure i.e. if you're just freezing the soccer ball or testing it outdoors while the temperature is below freezing.

If you freeze the soccer ball, it would become much harder, and if you kick it the wrong way it might hurt you, but as long as you are careful how and where you kick it (i.e. don't kick it really hard at first) then it should be quite safe.

Thanks and please let us know what your project goals are so that we know what you want to do.

Hi Kaitlin,

You will need some way to measure your results. Kicking a soccer ball would be difficult, because that would give you two variables. It would be difficult to control the force of the kick so that the only variable is the temperature of the ball. You could very gently roll the ball off the edge of a table or platform and measure the height that the ball bounces (measurements should be in a metric unit like centimeters because this is a science fair project). Or perhaps you could think of a better way to do this. Make sure you repeat your results at least two or three times for each temperature you studay.
