In this activity, learners discover how geologists use stratigraphy, the study of layered rock, to understand the sequence of geological events.

Using toothpicks, straws, or tubes of rolled up newspaper, learners create 3-dimensional models to illustrate the basic structure and function of the cell membrane, and place an object inside to repre

In this four-day lesson, learners identify three-dimensional forms in castle design, research different parts of the castle with a focus on their uses, and design and enlarge a banner for the great ha

In this activity, learners discover how NASA engineers develop experimental aircraft.

In this activity, learners work in NASA teams to build balloon-powered rockets using identical parts and compete to launch the greatest number of paper clips to "space" (the ceiling).

In this activity (on pages 12-15), learners make a crater model and test the effects of weather (rain) on its surface.

In this activity, learners create a soil and water model of a single-cell life environment and study living microorganisms.

This activity (on pages 23-27) lets learners simulate the work of scientists who take core samples of Earth's rocky layers to determine geological history.

In this outdoor activity, learners make models of homes that might protect small animals from the elements, then search living plants for real structures made by small animals.

Learners investigate a pre-constructed mystery tube to determine its interior mechanism.

In this activity, learners explore the "nuts and bolts" of gene chips.

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

Learners match puzzle pieces to outlines of a DNA strand. The puzzle pieces represent the four chemicals making up DNA base pairs: adenine, thymine, guanine, and cytosine.

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

In this "gross" activity (on pages 34-46), learners make a life-size model of a human digestive tract, and follow the life of a beef tapeworm as it makes its way through.

In this activity, (on page 6 of the PDF under SciGirls Activity: Dinosaurs) learners participate in a hands-on fossil excavation.

Learners observe two model atmospheres -- one with normal atmospheric composition and another with an elevated concentration of carbon dioxide.

This activity was designed for blind learners, but all types of learners can have a tactile opportunity to construct a karyotype, an organized model of an organism’s chromosomes, conveying the chromos

In this outdoor activity, learners design devices that will catch prey or gather plants.

In this activity, learners build a miniature wind tunnel to measure force. Learners construct the model out of Lexan plastic, a fan, and a precise digital scale.
