This investigation provides learners with a hands-on activity that simulates the changing relationship of surface areas-to-volume for a growing cell.

In this lab exercise, learners explore diffusion, cell membranes and particle size using beets and three alcohols.

This activity is about collecting and analyzing DNA as part of a criminal investigation.

In this activity, learners extract DNA from a strawberry and discover that DNA is in the food they eat.

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.
