Children think that heavy objects sink and light objects float. Is that always true? You might be surprised what objects actually do and do not float on water! Where are these principles seen in nature? What is a buoyant force or buoyancy? How does it work? Good explanations teach you how to teach these scientific principles with a variety of modeled examples that can engage your students in “Why things float”? What is surface tension? Watch Mr. McWiz demonstrate many engaging experiments that you can show your children. Mr. McWiz gives suggestions on possible math applications and fun lab sheets to use. Additional challenges are offered like: How can you get water to stick to a string traveling downward at a 45 degree angle in to a cup? How many paper clips can you get to float on water? Can you get six or more clips to float at the same time? How? Observe the amazement of pepper expanding quickly in a circle on the water’s surface. Let the kids have fun with match stick motorboats propelling themselves across water with just a pinch of soap. What do you think – will a container filled with large holes float on water? You could follow up these experiments with trying to find out which fruit items will float or what type of a soda pop can will float on water – like Diet Coke vs. regular Coke. Your children will have a new perception of why a water bug walks across the water – or why a steel aircraft carrier can float with all that weight. You will love these experiments as much as your children will – and feel a little better when the children ask you “Why?”$29.95
