This activity models the way Landsat satellites use a thermal infrared sensor to measure land surface temperatures.

This is an activity about center of gravity. Learners will balance a fork on a glass by finding its center of gravity.

In "Chemistry Makes Scents," participants use their noses to distinguish between chemicals with very similar structures.

In this activity, learners will create a model rocket out of an inflated balloon attached to a straw on a taught string.

In this activity, learners actually feel the difference in energy required to light two different types of light bulbs: incandescent light and LEDs.

Learners observe a bottle containing water and oil. They are invited to pick up the bottle and mix the contents together.

In this activity, learners will experiment with the physics of forces - kinetic energy and friction while making a moving toy woodpecker.

Learners combine hydrogen peroxide with three different forms of potato: raw chunks, ground chunks, and boiled chunks.

In this activity, learners will create glitter bottles with adult supervision. These are a fun way for little ones to practice observing and making comparisons.

In this activity, learners mix up a bubbly brew and examine density. Learners explore how they can make different materials fall and rise in water using oil, water, and salt.

This simple and engaging astronomy activity explains nuclear fusion and how radiation is generated by stars, using marshmallows as a model.

Discover how sound travels and what materials make better sound conductors. Can you hear better with your fingers in your ears? Find out with a coat hanger and some string!

In this activity, learners will explore the chemistry of cooking. They will learn about--and observe--the Maillard Reaction as they make their own browned butter.

In this activity, learners use mirrors to write secret messages to a friend. Use this activity to explore letters, optics, and/or symmetry.

This activity encourages visitors to build an electroscope—a simplified version of one of the tools scientists use to study the invisible forces on Earth and in space.

Molecular gastronomy is the scientific study of food preparation. Learners use self-assembly techniques to create edible capsules of chocolate syrup (food grade ingredients are required).

"Molecules in Motion" explores how materials behave and change in a vacuum.

This is an online activity about what would happen if we could travel at or near the speed of light.

In this activity, learners explore the flexibility of polymer chains by pushing sharpened pencils through a Ziploc bag.

In this optics activity, learners examine how polarized light can reveal stress patterns in clear plastic.
