In this activity (on page 1 of the PDF), learners make a "mini-globe" to investigate the causes of day and night on our planet.

In this activity, learners use multiple thermometers, placed at different angles, and a lamp to investigate why some places on Earth's surface are much hotter than others.

This fun and simple hands-on astronomy activity lets learners create 3D models of the Earth, Moon and Sun to demonstrate solar and lunar eclipses.

Learners demonstrate how water can distort, refract and magnify light.

In this activity, learners experiment and observe how the color of materials that cover the Earth affects the amounts of sunlight our planet absorbs.

In this activity, learners will make their own prism and use a glass of water to separate sunlight into different colors.

In this activity, learners investigate passive solar building design with a focus solely on heating.

In this math-based activity, learners model the intensity of light at various distances from a light source, and understand how astronomers measure the amount of sunlight that hits our planet and othe

In this activity, learners make their own flip book that shows real solar flares erupting from the Sun in November 2000. Step-by-step instructions are included with photos.

Many people think the different stages in the life of a star are actually different types of stars, rather than just stages in the life of a single star.

This fun and simple hands-on astronomy activity lets learners make 3-dimensional models of the Earth and Moon.

Learners construct one or more of the following kinds of sundials: a shadow plot, a horizontal sundial, and a diptych sundial.

In this activity, learners make scale models of the Sun and Earth out of paper mache.

Learners work in teams to design and build solar water heating devices that mimic those used in residences to capture energy in the form of solar radiation and convert it to thermal energy.

This activity shows you how to make amazing crystal spikes using Epsom salt and the sun.

This activity generates learner excitement about light through the creation of a room-sized rainbow.

This PDF contains 12 calendars (12 months). Each month contains activities about math. Things to do on familiar holidays (like July 4), less common holidays (like Backward Day), and any day.

In this activity, learners plan and create a 24-foot long, two-dimensional model of our solar system, and compare and contrast the differences between planets and the sun.

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.
