In this lab exercise, learners explore diffusion, cell membranes and particle size using beets and three alcohols.

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

Learners observe working lava lamps to understand how they work (included in PDF link).

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

In this activity, learners will turn healthy greens into crispy snacks. Explore concepts of nutrition, dehydration and cooking to create healthy food.

In this activity, learners explore color, light and shadow by creating their own puppets to hold in front of a light source.

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.
