In this activity on page 13 of the PDF, use a special plastic card that has been painted with a chemical that changes color when it is in UV light.

Did you know that using a lens one can bend light to make pictures of the world? It's true!

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

Learners will construct a model of a heart valve using a film canister, a piece of masking tape, and a piece of paper.

Learners will explore the chemistry of mucous and its importance to our health by following a process to make their own replica "snot." The activity includes a time and age recommendation, a materials

In this activity, learners explore different ways to stack cups to meet a personal goal.

In this meteorology activity, learners build weather vanes using straws, paperclips, and cardstock.

In this activity, learners use candy pieces and a cookie to make an accurate model of the Sun they can eat. Parts of the delicious model include solar granules, sunspots, and solar prominences.
