In this activity, learners create a three-dimensional sculpture while examining the characteristics of fish.

In this activity, learners explore the concepts of density and basic chemical reactions as they create a homemade lava lamp effect using water, oil, food coloring, and Alka-Seltzer tablets.

In this activity, learners investigate the basic crystal structures that metal atoms form.

In this math activity, learners sort patterns into similar "families" or groups that have the same pattern, but different symbols.

In this activity, learners will explore nature by creating food for birds. Learners will develop fine motor skills and engage in nature observation through this activity.

In this activity, learners construct bug models that "jitter" all over the table with just a battery, motor, and counterweight.

In this activity, learners design and build a NASA rover using raw pasta and candy with a limited imaginary budget.

In this activity, learners make a photographic image--without a camera!

In this fun snack and craft activity, young learners make "Ants on a Log" and their own model of an insect. The purpose is to learn the three main insect body parts—head, thorax and abdomen.

In this STEAM activity, learners create a "pixel tube" to explore reflections of light and color mixing.

In this activity related to nanotechnology, learners observe some of the effects that result from creating a thin layer of material several nanometers thick.

This activity was designed for blind learners, but all types of learners can explore the process of extrusion used to produce pipes and wires in industry.

In this activity, learners explore the engineering design process and the basic mechanics behind building bridges as they build one themselves using gumdrops and toothpicks.

In this activity, learners design and build their own parachute using household materials with the goal of landing their passenger safely on a target.

In this design challenge, learners will create wind-powered contraptions to transport a load, such as a cupcake or another small object, and test to see if they work.

In this activity, learners explore sound by constructing their very own bagpipe instrument.

In this activity, learners build a carousel toy that spins when pushed down.

In this activity, learners construct drums out of everyday containers (like bowls or food containers) and shrink wrap. Learners use a hair dryer to affix and tighten the shrink wrap to the container.

In this outdoor activity and game, learners collect and sort leaf samples to determine how many types of plants grow in the activity site.

The Ancient Egyptians used a naturally-occurring salt from the banks of the Nile River, called natron, to mummify their dead.
