This activity models some of the ways natural processes, such as erosion and sediment pollution, affect Earth’s landscape.

In this activity, learners explore sensors and focus specifically on how to measure humidity using a sensor.

In this physics activity, learners assemble and/or investigate a pendulum "snake." Several large steel hex-nuts are suspended on strings of successively increasing length to form a series of pendulums

In this activity, learners cut out and assemble wheels to explore how variations in fish body structures (mouth shape/position/teeth, body shape, tail shape, and coloration patterns) allow fish to sur

In this hands-on activity, learners use an assortment of (mainly household) items to complete Rube Goldberg-type challenges.

Learners use Duplo bricks to build antibodies with shapes that match model viruses.

Learners create three solutions with different levels of salinity. They compare the density of these solutions by coloring them and layering them in a clear plastic cup and in a soda bottle.

This activity is a whole-group kinesthetic demonstration that shows learners what it means to be in a "risk group" for developing heart disease based on family history and genetics.

Based of the The Tech Challenge 2015, learners will engage in two mini-design challenges related to seismic engineering.

In this activity, learners make an equatorial sundial, which is simple to construct and teaches fundamental astronomical concepts. Learners use the provided template and a straw to build the sundial.

This fun, nighttime hands-on astronomy activity lets learners explore how long it takes for light from different objects in the universe to reach Earth.

In this activity, learners explore how civil engineers solved the challenge of moving water via irrigation.

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.

A design challenge that takes paper airplanes into an entirely different direction: a magnus glider uses cups and and rubber bands to create a glider that uses the same forces that a curveball (from b

In this activity, learners observe mixtures of sand samples glued to note cards, and consider how sand can differ in size, shape, and color, and where it comes from.

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.

In this lab (Activity #1 on page), learners explore how we see color.

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.
