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

Learners observe a model of a cell and its chromosomal DNA made from a plastic egg and dental floss. Use this model to illustrate how much DNA is held in one cell.

In this geology activity, learners create a model using a mixture of salt and sand inside a CD case. When the case is tilted or inverted, the mixture dramatically sorts into a layered pattern.

If a sailboat is stranded because there is no wind, is it possible to set up a fan on deck and blow wind into the sail to make the boat move?

Groups of learners are provided with a generic car base and an egg. Their mission: design a device/enclosure to protect the egg on or in the car as it rolls down a ramp with increasing slopes.

In this lesson, learners develop a robot arm using common materials. Learners explore design, construction, and teamwork, as well as materials selection and use.

In this activity, learners construct their own small catapults using simple materials. Learners follow visual instructions to build their launching device.

In this activity, learners work in teams build and launch rubberband-powered foam rockets.

This activity helps learners visualize the Human Immunodeficiency Virus (HIV) by constructing three-dimensional HIV particle models from paper.

In this activity, learners use rice grains to model the composition of the atmosphere of the Earth today and in 1880. Learners assemble the model while measuring percentages.

In this activity, learners explore how genetic switches function and the role of genetic switches in the process of evolution.

In this activity, learners create 3D geometric shapes using straws and pipe cleaners.

In this activity, learners create models of ionic compounds and observe the chemical formula of binary molecules they have created.

Learners follow directions to construct a water-powered electrical generator using a turbine made from plastic spoons.

Using recycled materials, learners will design a transportation vehicle to carry an egg in an egg toss (a rudimentary model of a shock absorbent transport vessel).

In this engineering design challenge, learners make a bird and then control its flight with attached strings.

In this activity, learners construct a model of DNA to better understand the structure of DNA and protein synthesis.

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

In this activity, groups of learners work together to create edible models of chemicals involved in autotrophic nutrition.

In this activity, learners explore the design of tall structures such as skyscrapers and telecommunication towers.
