In this activity, learners make "totally tubular" forms of carbon. Learners use chicken wire to build macro models of carbon nanotubes.

In this activity, learners use chemistry to “self-assemble” gummy shapes. Learners discover that self-assembly is a process by which molecules and cells form themselves into functional structures.

In this activity on page 2 of the PDF, learners discover how color changes can help scientists distinguish between acids and bases.

In this activity (p.7-8 of PDF), learners examine fossil formation.

In this chemistry investigation, learners combine common cooking substances (flour, baking powder, sugar, salt, pepper, oil, water, food coloring) to explore mixtures.

In this activity, learners look at and touch marine animal skulls to compare them and think about what they eat.

In this "Sid the Science Kid" activity from Episode 106: My Mushy Banana, learners explore the effects of decay by comparing and contrasting something (an old pumpkin) that's decayed with the same thi

In this activity, learners use a chemical reaction to visualize where moisture forms on the body.

In this activity, learners play with surprising sand that doesn’t get wet! Learners explore how water behaves differently when it comes in contact with "magic sand" and regular sand.

In this activity, learners observe hard parts of sea creatures (shells, molts, etc.) to better understand marine environments.

In this activity on page 6 of the PDF (Get Cooking With Chemistry), learners investigate yeast. Learners prepare an experiment to observe what yeast cells like to eat.

Learners experiment to see which colors of light will cause a phosphorescent (glow-in-the-dark) material to glow.

Learners examine the properties of light by experimenting with an LED-flashlight and polarizing filters. When two polarizers are used, they block all light when they are placed at right angles.

In this activity on page 7 of the PDF, learners experiment with the interesting designs that can be made by painting on plaster.

In this activity, learners explore the magnetic field of a bar magnet as an introduction to understanding Earth's magnetic field. First, learners explore and play with magnets and compasses.

In this activity, learners simulate Otto von Guericke's famous Magdeburg Hemispheres experiment.

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