Insane Membrane | Cooking Up Science with Miss America

Learn about semipermeable membranes. 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. Let's 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.

Learn about concentrations of solutions. If you brew tea or coffee for too long, it gets really strong, bitter, and dark. But if you add water, you can lessen its strength. So, when we talk about how strong our coffee is, we are really talking about CONCENTRATION. Like stirring a teaspoon of sugar into a cup of tea, solids can have a concentration in a liquid, but first, they need to be able to dissolve into a solution (solubility). But, is there a limit to how much of a solid the solution can take in? Through some sweet treats, you can eat, let's explore the scientific concepts of concentration, solubility, and supersaturated solutions. I promise you it's going to ROCK! Developed for students in grades 6-10.
