In this outdoor/indoor activity, learners collect ants and dirt to create an ant farm in a cup that they can observe over time.

In this activity, learners will engineer their own weather vane. This activity includes step-by-step instructions with pictures and a "What's Happening?" section explaining how the activity worked.

In this game, learners cross off or color bingo squares in response to questions about their traits.

In this activity (3rd activity on the page), learners taste test different foods and categorize them as sweet, bitter, sour, or salty. Learners compare their results with the group.

In this activity, learners investigate the relative growth of lengths, areas, and volumes as cylinders are scaled up.

Use this activity (13th activity on the page) to introduce learners to the sense of touch. Learners collect objects of varying textures like feathers, rocks, sand, etc.

In this activity (on pages 15-18 of PDF), learners make a life-size two-dimensional paper model of their own skeletons.

In this activity, learners construct and launch rockets using simple materials and their understanding of chemical reactions.

In this chemistry activity, learners explore chemical reactions and their effects, including the kind of reaction in the human body that makes people burp!

In this design challenge activity, learners build a shock-absorbing system that will protect two “astronauts” when they land.

When you teeth clatter, they make quite the racket disproportionately to how much they actually sound to someone else.

In this activity, learners will build ramps and test how the laws of physics apply do different objects. Learners will explore physics and cause and effect through this activity.

In this activity, learners explore conservation of energy by experimenting with a solar cell light device.

In this activity, learners will explore the water cycle by creating a small atmosphere.

Have you ever heard of a camera without a lens? In this activity, learners create a pinhole camera out of simple materials. They'll see the world in a whole new way: upside down and backwards!

In this sunny day activity, learners compare how a cup of water and a cup of tonic water reflect or refract light in the sun.

In this activity, learners use an origami template to design eight amino acids. Learners configure the amino acids to form a protein. Use this activity to introduce proteins and amino acids.

In this activity, learners will create a magnifying glass called a waterscope, using water and household items, to examine various objects.

In this edible experiment, learners pour "Magic Shell" chocolate into a glass of cold water. They'll observe as pillow shaped structures form, which resemble lavas on the sea floor.

In this activity, learners explore nonrenewable resources and learn why these resources are finite.
