In this activity, learners examine fingerprints. Learners leave a hidden print on a surface and then make their own print detecting powder from graphite (found in pencils).

In this arts and crafts activity about animals and animal characteristics, learners will design animal hats and role-play as animals.

In this activity, learners use their imaginations and experiment with different materials to create bug hats.

Learners smell balloons filled with different scents to guess what's inside. From this, they infer the presence and motion of scented molecules.

In this activity (on pages 25-32 of PDF), learners make models of the inner ear out of pipe cleaners.

Learners use a simple process to extract DNA from strawberries.

In this activity, learners investigate the process of osmosis by adding salt to a sealed bag of raw carrots and comparing it to a control.

This activity explores the basic workings of a siphon, which is the core technology that makes toilets work.

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 activity about dinosaurs, learners first participate in a group discussion about where and when dinosaurs lived, how big they were, and who studies them and how.

This is an activity about dinosaurs, fossils, and the work of paleontologists. Learners use hand tools (paint brushes, scoops, and sifters) to unearth fossil specimens in tubs of birdseed.

In this activity, learners experiment with their voices and noisemakers to understand the connections between vibrations and the sounds created by those vibrations.

During this activity, learners will make different versions of "ooze" using varied proportions of detergent and glue.

In this activity, learners will model the mechanical weathering and erosion of rocks in a stream or river.

In this activity, learners discover that there is space between molecules even in a cup "full" of water. They first fill a cup with marbles, and then add sand to fill the gaps between the marbles.

As a group, learners investigate three packages which are all the same size and shape, but have different contents. One is filled with foam, one is filled with wood, and one is filled with metal.

This is an activity exploring color and color mixing.

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

This activity (on pages 21-32 of PDF) has learners act out several classic brain teasers.

In this activity, learners become detectives and use chemistry to investigate fingerprints.
