Observing Cells
Source Institutions
In this playful activity, learners explore the structure of the cell—the basic unit of every living organism—by creating a model of cell structures using soap bubbles, and by examining a slice of onio
Using Bubbles to Explore Membranes
Source Institutions
In this activity, learners use bubbles to investigate the structure and unique properties of cell membranes. Bubbles serve as macroscopic models that mimic the cells' phospholipid bilayers.
Lift Experiment
Source Institutions
In this experiment, learners investigate how the size of a wing affects lift. Learners count the number of pennies an egg crate plane wing can hold until the plane will no longer fly.
