The weather is lovely here in Virginia. Our neighborhood of about 100 houses has over 50 kiddos. Let me tell you, our neighborhood is lively! (Yes, we have our share of ‘Ding-dong Ditch’.) Let’s explore science outside. Gather a variety of balls: playground ball, bowling ball, tennis ball, golf ball, basketball, ping-pong ball, pinky ball, and bouncy ball. Go outside!
1. My favorite ball experiment is Small Ball, Big Bounce with a basketball and a tennis ball. Bouncing balls has kids stack and drop balls. Try a tennis ball and a ping pong ball. Use a playground ball or pinky ball with different ball combinations. The trick is to drop the two balls simultaneously. Next try three balls or four! Bonus points if you can recover all of the balls! The results are hard to measure because the top ball flies off.
2. Bouncy Ball Science Experiment is one ball experiment you should do inside. It is hard to recover those bitty, bouncy balls. The experiment evaluates a ball’s bounce depending on its temperature.
3. Try Ball Drop Rebound Test.
4. Make DIY Bouncy Balls and compare them with your ball collection.
5. Floating Ping Pong Ball requires a hair dryer. Consequently, this lab may need to be performed inside or on the porch. The porch might attract an audience, which always adds value to an experiment.
6. Floating Bowling Balls requires a large vessel and ice. 12 lb. bowling balls bobble in ice water; an 8-10 lb bowling ball floats. Why? They are less dense than cold water. A bowling ball which weighs more than 12 lbs. will sink.
7. Look at this unit about STEM Basketball and Explore the Science of Basketball. Ask your kiddo to study ways to improve his shot.
