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

In this activity, learners observe fly behavior and then build a flytrap.

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.
