Pump gas molecules to a box and see what happens as you change the volume, add or remove heat, change gravity, and more. Measure the temperature and pressure, and discover how the properties of the gas vary in relation to each other.

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 polymers.  They are all around us. From the proteins we consume to the plastic cups we drink from, polymers dominate our lives and our earth. They package our snacks but can also pollute our oceans. But do you REALLY know what a polymer is? Join Camille Schrier, science lover and Miss America 2020, to explore the science of polymers by making some slimy sodium alginate worms, and biodegradable corn plastic that is good for the earth!!

As part of the introduction to the Periodic Table of the Elements, students will be introduced to the idea of atoms, molecules, and compounds. The physical manipulation of marshmallows (atoms) and toothpicks (bonds) will create a visual representation of the molecular structure of water. A second step requires students to create a second molecule using similar materials and using the Periodic Table as a reference point.

How do microwaves heat up your coffee? Adjust the frequency and amplitude of microwaves. Watch water molecules rotating and bouncing around. View the microwave field as a wave, a single line of vectors, or the entire field.

Explore what makes a reaction happen by colliding atoms and molecules. Design experiments with different reactions, concentrations, and temperatures. When are reactions reversible? What affects the rate of a reaction?

Add different salts to water, then watch them dissolve and achieve a dynamic equilibrium with solid precipitate. Compare the number of ions in solution for highly soluble NaCl to other slightly soluble salts. Relate the charges on ions to the number of ions in the formula of a salt. Calculate Ksp values. Arabic Language.

Investigate what makes something soluble by exploring the effects of intermolecular attractions and what properties are necessary in a solution to overcome them. Interactive models simulate the process of dissolution, allowing you to experiment with how external factors, such as heat, can affect a substance's solubility.

Watch different types of molecules form a solid, liquid, or gas. Add or remove heat and watch the phase change. Change the temperature or volume of a container and see a pressure-temperature diagram respond in real time. Relate the interaction potential to the forces between molecules.
