Has your kid noticed how much bigger the moon looks when it's low in the sky? Here's an activity you can do to show them that it's just an optical illusion.

The weather is a key kindergarten science concept. With this activity your child will learn about wind direction and create a self portrait, too!

Young physicists learn about apparent weightlessnessâthat weird sensation you sometimes feel in elevators, turbulent airplanes, and roller coasters.

In this experiment, students will discover how heat and pressure turn clay into slate, phyllite, and finally schist.

What makes your shadow dance around all day? Let's play detective and find out why that sneaky shadow never stays in one place for long.

What better way to nurture your child's imagination than by making a fairy house out of materials found in nature!

Children use their design thinking skills and powers of observation to create and construct a bird nest.

Using a toy race car kids create a visual model of the Doppler Effect.

We all know that the Moon has different phases, but it can be hard to figure out why. Try this activity to see how the Moon's phases really work.

Show your child the solar system and let them explore the stars and space by creating a painting. It's a fun and easy way capture your child's imagination.

Introduce your child to the world of motion and physics with a bit of marble play inspired by Sir Isaac Newton!

Believe it or not, images that are cast upon your eye's light-sensitive screen (called the retina) are upside down. Here's a fun, fast experiment to prove it!

Household items and a bit of imagination will create a CSI kit for your child to have investigative adventures with. Explore the world of forensic science!
