In this activity, learners will discover how fossils are dug out of the earth by carefully exposing treasures hidden in an artificial rock that is easily made at home.

Pairs of learners play the roles of programmer and robot. The programmer gives specific directions to the robot to accomplish a simple task (e.g. walk across the room and pick up a pencil).

In this chemistry activity, learners transform two ingredients (4% polyvinyl alcohol solution and 4% borax solution) into gooey slime.

In this engineering activity, learners construct sturdy geodesic structures out of gumdrops and toothpicks. Use this activity to explore engineering principles as well as sturdy shapes and triangles.

The goal of this activity is to design the fastest sailboat or one that carries the most treasure.

In this physics activity, challenge learners to make a race-car out of a coffee can and rubber band. Demonstrate motion, forces, kinetic and potential energy and friction.

In this activity, learners will create their own bubble solution. Learners will explore chemistry, geometry and trial and error through this activity.

In this activity, learners make prisms from gelatin. Learners then shine light through the prisms and discover what happens. This activity introduces learners to the idea of refraction.

Learners design and build a roller coaster using simple materials. Learners experiment with potential and kinetic energy to get a marble to follow a track into a cup.

Learners make self-assembled polymer spheres as a model for the lipid nanoparticles found in COVID-19 mRNA vaccines.

In this activity, learners will make their own "ball bearing" with two jar lids, marbles, and some household supplies.

This is a quick game about self-assembly (page 2 of PDF under Self-Assembly Activity). Like the molecules of DNA, learners will self-assemble into a pattern by following a simple set of rules.

This fun and simple hands-on astronomy activity lets learners imagine what would happen if our Sun were replaced with a black hole.

In this quick activity about pollutants and groundwater (page 2 of PDF under Water Clean-up Activity), learners build a model well with a toilet paper tube.

In this physics activity (page 2 of the PDF), learners will explore the concept of thermal conductivity and learn the differences between high and low thermal conductivity.

Learners color and cut out a spiral-shaped snake. When they hang their snake over a radiator, the snake spins.
