Mr. McWiz teaches you how to teach three reasons that objects float on  water. 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
