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

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

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

How does a green roof, or roof covered by plants, affect the temperature of the inside and outside of a building? Learners design and build houses to find out the answer.

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.

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.

Teams of learners use a series of stick figures made from pipe cleaners to model a dance routine. Then, they use this model to communicate to another learner who performs the dance routine.

In this online game, learners run an outer space drink stand and thirsty alien customers are on the way.

Learners model the Sun-Earth-Moon system to show what causes the Moon's appearance to change when viewed from the Earth.

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

In this activity, learners solidify their conceptualization of cells by building a model of a cell in a ziplock bag.

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.

In this activity, learners explore the size and scale of dinosaurs. Learners listen to "Dinosaurs, Dinosaurs" by Byron Barton to understand some background information about dinosaurs.

In this activity, learners plan and create a 24-foot long, two-dimensional model of our solar system, and compare and contrast the differences between planets and the sun.

No glue is needed for learners of any age to become marshmallow architects or engineers.

This paper describes a working-model demonstration of Ernest Rutherford's 1911 experiment about the nature of atoms.
