Home Learning | Cooking Up Science with Miss America

Episode 7: If you put eggs and sand through a colander, would they both fall through? Probably not. Only the sand would actually pass through the holes of the colander because the eggs are too large. The colander acts as a semipermeable membrane, allowing some materials through but not others. Lets explore some other semipermeable membranes -like what surrounds our cells to help keep our bodies working and healthy. And eggs are like giant cells. They are a perfect thing to use to explore the science of semipermeable membranes, osmosis, and diffusion. We'll even experience a cool chemical reaction when we place an egg in vinegar. What do you think will happen when this chemical reaction is complete? Developed for grades 6-8 and correlated with Virginia Standards of Learning.

Produced by Camille Schrier, Miss America 2020, in partnership with VPM.

LS2  The student will investigate and understand that all living things are composed of one or more cells that support life processes. Key ideas include:
e) cellular transport (osmosis and diffusion) is important for life processes.
