In this activity, learners discover that the way a material behaves on the macroscale is affected by its structure on the nanoscale.

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 environmental science activity, learners research what is essential for plant life and the necessary components of soil to support plants.

This activity was designed for blind learners, but all types of learners can use it to investigate how different materials vary in their conduction of heat.

In this activity, learners explore the invisible infrared radiation from an electric heater.

In this activity (page 6 of the PDF), learners will observe both a chemical and a physical change.

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).

This activity/demo introduces learners to aerogel, a glass nanofoam. Learners discover how aerogel is made and how well it insulates as well as learn about aerogel's other unique properties.

This lesson focuses on two simple activities that younger learners can do to gain an appreciation of nanotechnology. First, learners measure their hands in nanometers.

In this activity, learners are challenged to design, build and test a birdhouse that will stay cool in the sun.

In this activity, learners conduct a controlled experiment to examine how temperature will affect the height of a soda geyser.

In this chemistry meets cooking activity, learners make carbonated, vanilla ice cream using dry ice and denatured ethanol, which are both inexpensive and accessible.

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

In this activity, learners will be introduced to biomass gasification and will generate their own biomass gases.

In this activity, learners build models of comets, using edible materials, to learn about comets' structure.

This interactive demonstration reintroduces learners to three states of matter (solid, liquid, gas), and introduces them to a fourth state of matter, plasma.

In this activity, learners work in teams to investigate the composition of unseen materials using a variety of tools.

This activity (on page 2 of the PDF under SciGirls Activity: Lift Off) is a full inquiry investigation into the engineering challenges of sending scientific sensors into space.

In this outdoor, winter activity, learners find living green plants under the snow and determine the light and temperature conditions around the plants.

This activity models the way Landsat satellites use a thermal infrared sensor to measure land surface temperatures.
