In this classic memory game (on pages 37-45 of PDF), learners turn over tiles to reveal images on the back.

In this simulation of natural selection, learners use binder clips in three different sizes to represent the diversity of beak sizes in a bird population.

In this two-part activity, learners map a navigation plan to get from Earth to Mars and back. In activity one, learners represent the orbital paths of Earth through dance and dramatic movement.

By playing a card game similar to "Go Fish," but based on the stages of metamorphosis, learners will be able to see how insects change in form as they grow and will consider the advantages of undergoi

This is a series of demonstrations about different electrical and magnetic phenomena.

In this activity about the relationship between food and energy (page 5 of PDF), learners conduct an experiment to compare how much energy is released as heat from two different foods.

In this activity (on pages 49-54 of PDF), learners play with tangrams, a set of triangles, squares and a parallelogram that can combine into a larger square as well as all sorts of other shapes.

In this activity (on page 7), learners explore the meaning of a "carbon sink." Using simple props, learners and/or an educator demonstrate how plants act as carbon sinks and how greenhouse gases cause

In this experiment, learners will conduct chemical and physical tests to identify mystery substances.

In this activity, learners examine antibodies and antibody recognition using a model.

In this activity, learners will create a diagram of the ocean zones and determine what organisms live in each zone.

In this activity, learners play a series of simple games to investigate navigation without visual and sound cues.

In this activity about the relationship between food and energy (page 1 of PDF), learners observe and quantify the growth of yeast when it is given table sugar as a food source.

In this culinary activity, learners use multiple senses (sight, smell, touch, and taste!) to explore real seaweed samples.

In this activity, learners explore what makes a boat float and sink. They examine and test various objects to determine why objects float or sink.

In this design challenge activity, learners use two helium-filled balloons to build a blimp that can travel in a straight path across the room.

In this two-part activity, learners work in pairs to examine the four basic stages of a turbine engine.

In this math lesson, learners participate in several activities where they apply measurement skills.

In this activity learners explore surface tension. Why are certain objects able to float on the surface of water and how do detergents break the surface tension of water?

In this activity about the heart (on page 22 of the PDF), learners examine sheep or chicken hearts to learn about the heart's structure and the flow of blood through the heart.
