Is freezing a rubber ball with liquid nitrogen a good 5th grade science project?

Question

well my little bro is in grade 5 and i was wondering this

Answer 1

i don't know if a 5th grader should be handling liquid nitrogen, but otherwise it sounds like a good idea. maybe he should try something more simple like something to do with buoyancy. something inexpensive, and danger-free.

Answer 2

I would only say 'yes' if there is a purpose to this experiment.  What would be you hypothesis?  What is this experiment good for or supposed to prove....

Make sure you look over his hand-out on science project...you will see a list of things required....if not look up the scientific method so he can get a good grade...

Answer 3

Yes.

The hypothesis could be:

Rubber loses it's bounciness when it's extremely cold.

(Yes or No?)

The liquid nitrogen would just be an extreme tool in my eyes. you could just use a freezer though this is way cooler (litterally)
