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

In this activity, Christina Elson, an archaeologist from the American Museum of Natural History, guides learners as they investigate an "artifact" and record their observations in a field journal.

In this card-based personal choice activity, learners review and sort COVID-19 and vaccine science information.

In this chemistry activity, learners will learn how to make their own pH indicator using cabbage leaves, and then test common household items with their homemade indicator.

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

In this craft-based activity, learners make DNA sequence bracelets that carry the code of an organism such as a human, trout, chimpanzee or butterfly.

In this movement and measurement activity, learners jump as far as they can three times, and compare their longest jump to the longest jump of their friends, classmates and/or family members.

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.

In this activity, learners will investigate and compare the root systems of plants. Explore how weed and edible plant roots differ, and take a closer look inside with the careful use of a knife!

In this activity, learners make balloon models of disease-causing bacteria.

In this activity, learners balance chemical equations and discover the law of conservation of mass. Learners use coins to model molecules to balance the equations.

In this activity, learners explore a bucket of sand and beach objects.

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

With a laser pointer and some household items, learners can create their own laser light show. They can explore diffuse reflection, refraction and diffraction.

This fun and simple activity is a rubberband rocket design challenge! Learners will explore how tail fins can help to stabilize a flying object, while also exploring potential and kinetic energy.

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 activity (5th activity on the page), learners explore how what you see influences taste. In experiment 1, learners taste five sodas, one of which is clear soda with orange food coloring.

Learners observe different paper samples under ordinary room light and under a black light to learn some of the chemical differences between different types of paper.
