White, fluffy snow! And what do you do with snow when you are a kid? Have a snowball fight!įor this winter STEM challenge, the kids will go through the scientific method and find out which object will go farther when you launch different items using a popsicle stick catapult! Snowball Fight Winter STEM Challenge Materials: Once everyone has built their catapults, pair. Slide the stack of small sticks towards the rubber band until the catapult feels solid and strong when the non-notched ends of the large popsicle sticks are compressed together and then released.
