Middle-schoolers still enjoy playing with bubbles! In this series of eight laboratory activities, science learners explore convex and concave surfaces, angles, gas laws, buoyancy, density and more! 

Even middle schoolers still enjoy experimenting with bubbles! They execute a series of experiments enabling them to distinguish between convex and concave surfaces, explore the properties of buoyancy, surface tension, and density,...

Students are challenged to eat some candy as a cell would need to do it. By solving this problem students simulate the cell process called endocytosis. They think about some of the problems that arise when a cell ingests food.
