In this hands-on experiment, kids use chemistry to explore whether acids or bases are better at restoring a penny’s shine.

In this environmental health activity, learners investigate their breathing and pulse rates, and learn how these measurements are affected by physical activity.

In this activity, learners compare and contrast their own skin (including the area covered) with that of an orange.

In this experiment, learners try different liquids to see which ones clean pennies best. Liquids to try include water, lemon juice, cola, vinegar, and dishwashing detergent.

In this activity, learners construct possible food webs for six different ecosystems as they learn about the roles of different kinds of living organisms.

In this activity, learners write invisible messages on goldenrod paper, and make the message appear and disappear using acids and bases.

In this water activity, learners test which objects float and which sink. Learners discover that objects behave differently in water.

In this water activity, learners explore how water drops behave on different surfaces.

In this activity, learners build penetrometers to test leaf toughness. Biologists measure leaf toughness to study the feeding preferences of insects and bugs.

In this activity on page 7 of the PDF, learners explore how engineers characterize building materials.

In this activity, learners explore the relative size of the Sun and Earth as well as the distance between them.

In this environmental health activity, learners grow and observe bread mold and other kinds of common fungi over the course of 3-7 days.

In this hands-on science experiment, students combine their understanding of the different states of matter and the characteristics of various chemical reactions.

In this activity on page 4 of the PDF, explore the unique molecular structure and conductive nature of graphene. Learners construct a circuit with a battery and LED bulb.

In this activity, learners repeat patterns in two and three dimensions to create tessellations.

In this water activity, learners build boats that float and sink. First, learners listen to the book, "Who Sank the Boat" and practice making predictions throughout the story.

In this hands-on activity, learners build their own kaleidoscopes and explore how light can reflect of off surfaces such as mirrors, to produce beautiful patterns.

In this hands-on activity, learners determine the types of chemical reactions achieved when combining different household products.

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

In this simple activity, learners discover how a mere piece of paper can be used to hold up the weight of a heavy book.
