In this activity, learners examine how brine shrimp populations can survive in some of the harshest environments.

In this activity, learners investigate the different salinity levels of oceans, rivers and estuaries.

The purpose of this lab activity is to demonstrate (through simulation) how DNA fingerprinting (or DNA profiling) might be used to solve a crime.

In this activity, learners explore how nanotechnology is being used to create new types of protective fabrics.

The major goal of this math lesson is to have learners collect data from a variety of experiments, determine what models best fits their data, and explain why their models are best.

In this activity/demo about piezoelectricity, learners discover how some crystals produce electricity when squeezed.

In this activity, learners construct a device that allows them to view 2-D images in 3-D.

This activity uses LEGO® bricks to represent atoms bonding into molecules and crystals. The lesson plan is for a 2.5 hour workshop (or four 45-minute classes).

In this activity, learners conduct tests for proteins, glucose, and starch.

In this activity, learners investigate the Moon's infancy and model how an ocean of molten rock (magma) helped shape the Moon that we see today.

In this activity, learners model ancient lunar impacts using water balloons.

This activity has learners interacting with live crayfish, but could be adapted for a variety of similar hardy and interesting organisms.

This is a series of demonstrations about different electrical and magnetic phenomena.

This laboratory activity helps learners understand the concept of biological succession by simulating the process in a microenvironment with various protozoans.

In this health, cooking, and math activity, learners explore nutrition and examine nutrition labels.

In this activity, learners examine antibodies and antibody recognition using a model.

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

In this activity, learners explore accuracy and precision.

In this activity, learners design a therapeutic agent to image and/or cure various diseases in the respiratory system.

In this two-part activity, learners work in pairs to examine the four basic stages of a turbine engine.
