Kids will conduct a cool limewater carbon dioxide test that can be performed with common household materials to learn about the chemistry of this common gas.

In this activity, your child will make her own "quicksand" to better understand how a substance can be both fluid and solid at the same time.

In this cool experiment, learn about the forces of resistance in a liquid and race marbles in a cylinder to find out which fluids have a high viscosity.

This science project examines the thermal properties of several major greenhouse gases.

In this science fair project, we'll use a liquid crystal thermometer to find out whether exercising makes a difference in people's temperature.

Invite your fifth grader to test the different rates of liquid absorption in synthetic and cotton materials, such as nylon and cotton.

This goofy scramble book activity will bring laughs...but also some good, solid comprehension skills too!

In this science experiment, observe convection currents forming and learn about how heat energy moves in liquids from hot to cooler areas through convection.

In this science fair project, kids observe the expansion of liquids when frozen and determine if some liquids expand more than others in the freezing process.

How can you get your child started if they're totally stumped? All it takes is a solid plan, man. Here's how to get started.

Science fair project that develops latent fingerprints on a non-porous objects by converting superglue from a solid state to a gaseous state.

Saturn is the ringed planet in our solar system, a gas giant with rings made of ice and dust. Let's make a cool scale model with an old CD and some glitter!

.Have you ever had problems with your wifi signal strength? In this experiment you will learn about how wireless signals pass through the air and solid objects.

see whether all liquids evaporate at the same rate. In other words, does water evaporate at the same rate as juice?
