In this activity, learners will create a soil profile in a bottle. They will learn about the organic and inorganic matter found in soil and observe as it separates into layers in the bottle.

In this activity, learners explore the relative sizes and distances of objects in the solar system.

In this activity, learners construct a coastal landmass from sand and add features such as tidal creeks and barrier islands.

In this artistic activity, learners blow up a smaller picture into a larger one, by using a grid.

In this activity, learners use maps to locate the Arctic region and use a word game to discover the types of resource people need to survive in the extreme climate.

In this activity, learners build a kite out of paper, change it, and try to make it fly even better. With their new knowledge of kite making, students can then go on to create their own kite designs.

In this activity, learners make a foam packing peanut "flink"--neither float away nor sink--in water. Learners experiment with materials to make a Flinker that "flinks" for 10 seconds.

In this activity, learners will explore probability using dice. They will predict and then roll the dice to observe how many rolls it would take to repeat a matching pair. Learn track predictions vs.

In this math activity, learners play a game that helps reinforce learners' understanding of the coordinate system.

In this activity about magnetism (page 11 of the pdf), learners will experiment with magnets to explore how opposite poles attract and similar poles repel in magnetism.

In this optics activity, learners use everyday materials to make a color wheel. When learners spin the wheel like a top, they will be surprised to see all the colors mixing together to appear white.

In this activity, learners explore the potential of interchangeable standard parts to create a large number of unique creations in different combinations.

In this quick activity, learners practice locating a constellation in a map of very dark skies.

In this activity, learners thread colored beads onto string. Each beach represent a process of the water cycle.

In this design challenge activity, learners invent a way to send a Ping-Pong ball flying high enough to catch it - like football with a twist!
