In this activity, learners will build a bee hotel for pollinators. Learners will explore building and ecology through this activity.

In this activity about vision and optical illusions, learners conduct a simple test to demonstrate how our eyes create "afterimages." Learners stare at a black cardboard bat for at least 30 seconds an

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 conduct a waste audit and use their findings to implement a plan for reducing trash.

In this activity (page 12), learners explore how molecules self-assemble and how molecules must fit together, like a lock and key, in order to identify each other and initiate a new function as a comb

Look at pictures through different color filters and you'll see them in a new way. People have used color filters in beautiful photography or sending secret messages.

In this activity, learners will estimate how many seeds are in a fruit or vegetable, then count to find out. The result: mix estimation with healthy eating.

In this outdoor game, learners simulate a herd of deer trying to survive in an area called the "home range." Learners explore the concept of "carrying capacity"—what size population of an organism can

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

This fun and simple hands-on astronomy activity illustrates the value of supernovae in the universe.

In this goopy activity (page 2 of PDF under GPS: Glaciers Activity), learners will model glacial movement with “gak,” a white glue and liquid starch mixture.

This activity (located on page 3 of the PDF) is a full inquiry investigation into bird behaviors.

In this outdoor, night-time activity, learners discover how to spot eye-shine (reflection of light from an animal's eyes) by using a flashlight to play a simulation game.

En esta tira cómica, Mateo y Cientina emplean su conocimiento de la química y las medidas para esta actividad deliciosa - ¡hacer helado!

We don't normally view people upside down and so our brains aren't accustomed to it.

In this 6-7 day investigation, learners begin with an introduction to seamounts that are present in the Gulf of Alaska.

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

In this simulation, learners act out each digestive function of the organs, tissues, and cells in the digestive tract.

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 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.
