In this activity (p.26 of PDF), learners discover why mushrooms have spots. Learners use a balloon, toilet paper, and water to simulate what happens as mushrooms grow.

In this activity, learners create channel features with flowing water, comparing their observations to real images of Mars and Earth taken by satellites/orbiters.

In this activity about dinosaurs and survival, learners use scrap materials to create a miniature dinosaur habitat that includes a food source, water source, and shelter.

In this geology activity (page 6 of the PDF), learners explore how carbonic acid can slowly dissolve limestone and form caves.

This activity demonstrates liquefaction, the process by which some soils lose their solidity during an earthquake.

In this activity, learners separate materials based on their special properties to mimic the way recyclables are sorted at recycling centers.

Learners build models of sinkholes to gain an intuitive knowledge of their physical aspects.

In this activity, learners examine the properties of different seaweeds, investigate what happens when powdered seaweed (alginate) is added to water, and learn about food products made with seaweed.

In this experiment, learners examine the way oil affects bird feathers and test different cleanup methods to find out which works best.

In this activity, learners test how cornstarch and glitter in water move when disturbed. Learners compare their observations with videos of Jupiter's and Earth's storm movements.

This display shows the dangers of acid rain on buildings and other structures as two concrete bunny rabbits are disintegrated by sulfuric acid. Learners scrape chalk onto the concrete bunnies.

In this activity on page 7 of the PDF (Chemistry—It’s Elemental), learners use iodine to identify foods that contain starch.

In this activity, learners model how the Moon's volcanic period reshaped its earlier features.
