Hi Students! I have a fun challenge for you today. When I was in High School, my physics teacher challenged us to build a boat out of CARDBOARD that at least two students could sit in and paddle across the school pool. My friend and I were successfully able to meet the challenge and sat in our boat while we watched others attempt the challenge. We were not sunk until the post-race water fight. So, I challenge you to build a cardboard boat. If you have a pool and enough cardboard for a full on test with a person - great! If you are like most of us, I would like your boat to hold 9 ounces of weight and be able to stay afloat for 1 minute in the bath tub. Materials:
Parent Tip: A bag of rice or beans or cans of tuna make a good weights. Be sure kids design a boat large enough to hold the test weight. How To Links & Explanation: This video includes a good discussion of buoyancy and shows several boat designs to get your kids thinking. The actual challenge is presented at the end (beginning at 4:25). Thanks to the James Dyson Foundation for this activity. Share Your Experience: If you do this experiment feel free to post pictures in the comments section below. Happy Engineering!

welcome!
Every school day I will post a new experiment for you to try at home. Some may be familiar to you - as they are my favorites from class - but most will be experiments I found on the web that have readily available materials. Happy Sciencing! Earn a Patch
