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 work in teams to construct and test fly drinking straw rockets. Learners explore how changing the rockets' fins affect flight distance.

Build your own version of a favorite carnival game, in which a marble races down a maze consisting of rows of nails.

In this optics activity, learners make a lens and explore how the eye manipulates the light that enters it.

In this chemistry activity, learners use spaghetti to explore density and chemical reactions.

In this chemistry activity, learners use yeast and hydrogen peroxide to generate a gas (oxygen) and test some of its properties.

This activity (on page 3 of the PDF under GPS: Body Electricity Activity) is a full inquiry investigation into conductivity.

In this activity on page 6 of the PDF (Chemistry—It’s Elemental), learners explore some of the properties of copper using a few common household ingredients.

Using paper, paper clips, an index card, and tape, teams of learners design flying devices to (1) stay in the air as long as possible and (2) land as close as possible to a given target.

In this activity on page 7 of the PDF (Water in Our World), learners make their own water treatment systems for cleaning water.

In this activity on page 8 of the PDF, learners investigate vitamin C. Learners conduct a chemistry experiment to determine if Tang drink mix or orange juice contains more vitamin C.

In this activity, learners build their own sound machines and explore the interplay of motion and sound.

In this matchmaking activity (on page 2 of the PDF under GPS: Animal Scent Activity), learners will each have a scented cotton ball taped to their shoulder. The scent (e.g.

Whether it's the genetic code, an ancient language, or patterns of light in a distant galaxy, scientists often have to play the role of decoder.

In this chemistry activity, learners use mossy zinc (or a galvanized nail) and hydrochloric acid to generate hydrogen gas and test some of its properties.

In this chemistry activity, learners discover that the weight of the product of combustion is greater than that of the starting material.

In this simple game, learners start to understand how to sort and categorize objects by trying to guess the connection between three items that someone else has chosen.

In this activity, learners build magnetic towers to explore the forces and properties of magnets.

In this activity about heart health (on page 27 of the PDF), learners measure their heart rates after a variety of physical activities and compare the results with their resting heart rates, and with

In this experiment, learners use a blow dryer and water bottle to observe and record changes in air pressure caused by changes in temperature.
