In this activity, learners will investigate how craters are made and the different factors that contribute to size left from the impact.

Learners investigate weight by building a spring scale. They observe and record how it responds to objects with different masses.

In this activity learners compare the bounciness of warm and cold racquetballs to see if temperature makes a difference in how well they bounce.

In this activity, which requires adult supervision, learners get to explore the awesome power of chemistry.

In this activity about electricity, learners explore what happens when you blow a fuse.

Learners investigate signs of a chemical reaction when they mix vinegar and baking soda. In addition to a gas being produced, learners also notice the temperature decreases.

Many germs spread by our hands, and often times, people don't wash their hands well enough to get rid of germs.

In this activity, learners will imagine the challenges and opportunities of asteroid mining.

In this activity, learners explore nonrenewable resources and learn why these resources are finite.

In this Engineering Design Challenge activity, learners will use balloons to investigate how a multi-stage rocket, like that used in the Interstellar Boundary Explorer (IBEX) mission, can propel a sat

This activity provides instructions for building a mirrored tube--a smaller and simpler version of a submarine's periscope--that lets you see around corners and over walls.

In this activity about electricity and magnetism, learners examine what happens when a magnet exerts a force on a current-carrying wire.

This activity was designed for blind learners, but all types of learners can use it to investigate how, in a one-celled organism such as a bacterium, the division of cells increases the number of cell

In this activity, learners build a LEGO® structure while wearing mittens. This activity shows learners how difficult it is to build small things when your tools are too big.

In this activity, learners build a musical drum using a cardboard tube, plastic wrap, and beads.

In this activity, learners build cars using syringes and water-powered hydraulics. Learners construct the car frame out of cardboard and set up a hydraulic system to raise and lower the car.

Learners make kimchee or sauerkraut, which is really just fermented cabbage, in a 2-liter plastic bottle.

In this activity, learners examine the parts of a thermometer. After placing a thermometer in hot and cold water, learners look at molecular model animations of the liquid in a thermometer.

In this group activity, learners will explore the characteristics, functions and uniqueness of the mangrove tree.

Learners explore the field of civil engineering by making a bridge using spaghetti as their primary building material.
