Learners investigate the concept of humidity by using a dry and wet sponge as a model. They determine a model for 100% humidity, a sponge saturated with water.

In this detailed activity (on pages 9-18), learners investigate the body parts of a parasitic ascaris worm by making and dissecting clay models.

Ocean acidification is a problem that humans will have to deal with as we release more and more carbon dioxide into the atmosphere.

Using pipe cleaners, straws, and beads, learners explore the building blocks of life by creating their own model of DNA.

Make a big canvas of iridescent color with pvc pipe! In this Exploratorium Science Snack, you'll need to cut and assemble some PVC pipe, but the pay-off, the soap-bubble canvas, is big.

In this activity, learners build a 1:140 "scale model" of NASA's X-33 Reusable Launch Vehicle (RLV) Technology Demonstrator, and investigate how the model dimensions compare to the real vehicle.

In this outdoor, sunny day activity, learners experiment with paper leaf models to discover how some desert plants conserve water.

In this activity, learners imitate the way vocal cords work by building a model from a plastic cup, rubber band, and a straw.

In this activity, learners make scale models of the Sun and Earth out of paper mache.

Learners build a model of a pollution control device--a cyclone. A cyclone works by whirling the polluted air in a circle and accumulating particles on the edges of the container.

“Exploring the Solar System: Big Sun, Small Moon” is a hands-on activity that explores the concept of apparent size and allows visitors to experience this phenomena using familiar objects—a tennis bal

In this activity, learners make a 3-D model of DNA using paper and toothpicks. While constructing this model, learners will explore the composition and structure of DNA.

“Exploring the Solar System: Pocket Solar System” is a hands-on activity in which visitors make a scale model of the distances between objects in our solar system.

In this activity, learners are challenged to design and build a miniature tree house in a potted plant. This activity uses engineering concepts to encourage creativity.

In this activity (located on page 2), learners will construct tiny model geysers out of film canisters, warm water, and antacid seltzer tablets.

Get a roll of pennies, throw them on the ground, then remove those that only show tails, and repeat with the ones left over.

This activity (located on page 3 of the PDF under GPS: Glaciers Activity) is a full inquiry investigation about the different causes of glacial melt.

Learners will build a homemade pump using a balloon, a mason jar, and some straws.

In this activity, learners construct models of plants that are adapted to living under specific environmental conditions.

In this engineering/design/arts and crafts activity, learners design and build "platforms" or "bridges" that can hold weight, and test which glue makes the strongest structure.
