This lesson focuses on how to measure at the nanoscale and provides learners with an understanding how small a nanometer really is.

In this activity related to microbes, learners create scale models of microorganisms and compare relative sizes of common bacteria, viruses, fungi and protozoa using metric measures: meters, centimete

This activity (located on page 3 of the PDF under GPS: Balloon Fiesta Activity) is a full inquiry investigation into Bernoulli’s principle and airplane wings.

In this engineering activity, learners build a device (an anemometer) to measure how fast the wind is blowing.

Learners construct and launch paper helicopters.

In this activity, learners explore conservation of energy by experimenting with a solar cell light device.

In this activity, learners will build the highest tower they can out of recycled materials.

Build a house you can fit inside, using cardboard tubes.

In this activity about saturation (page 1 of PDF under SciGirls Activity: Sand Dunes), learners will build a series of sand castle towers using a 16 oz cup.

In this experiment, learners construct an equilateral triangle using graph paper, a pencil, protractor and ruler. They also make a "laser triangle" using a laser pointer and front-silvered mirrors.

In this activity, learners use a compass, powerful magnet, and copper magnet wire to build a special generator known as a dynamo.
