In this activity, learners will measure the length of their shadow from the Sun and compare it three to four months later.

In this exercise (Activity #2 on page), learners test their distance vision to evaluate their overall eyesight.

In this activity, learners investigate parallax, a method used to measure distances to stars and planets in the solar system.

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 international citizen science activity, learners measure their night sky brightness and submit their observations into an online database.

In this activity, learners make an equatorial sundial, which is simple to construct and teaches fundamental astronomical concepts. Learners use the provided template and a straw to build the sundial.

In this activity, learners explore how and why rainbows form by creating rainbows in a variety of ways using simple materials. Learners create rainbows indoors and outdoors.

In this activity, learners use a compact disc to make a spectrometer, an instrument used to measure properties of light.

In this activity, learners build a simple pinhole viewer. They use this apparatus to project images from a variety of light sources, including a candle, the Sun, and the Moon.

Use this hands-on activity to demonstrate infrared and thermal radiation.

In this sunny day experiment, learners measure and compare how quickly light and dark colored materials absorb heat.

In this three part activity, learners explore and experiment with shadows to learn about the Sun's relative motion in the sky.

In this activity on page 13 of the PDF, learners use a laser pointer (with known wavelength of light) to measure the thickness of a human hair.

In this activity, learners will measure the length of a shadow and use the distance from the equator to calculate the circumference of the earth.

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.

This activity (on page 2 of the PDF under SciGirls Activity: Doghouse Design) is a full inquiry investigation into absorption and reflection of radiant energy.
