In this physical sciences activity, learners explore how passive solar design increases energy efficiency.

In this activity related to climate change and data analysis, learners examine temperature and precipitation data to determine if climate variations are due to El Niño.

This activity helps learners understand how the angle of the Sun affects temperatures around the globe.

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

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 will compare predicted and observed tides using data from The National Oceanic and Atmospheric Administration(NOAA).

In this activity, learners will discover how our universe is continuously expanding.

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

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

In this activity, learners act as the Earth and observe how different angles between the Sun, Earth, and Moon affect the phases of the moon we see each month.

This activity provides instructions for learners to create models of the Earth and then to model a "day" on Earth as well as modeling the seasons.

In this activity, learners create a "mini sky" in a glass of water in a dark room.

In this activity, learners observe the moon each night for a month and draw their observations in a Moon Watch Log.

In this sunny day, outdoor activity, learners observe changes in shadows over time. The activity also helps to develop a sense of the Earth's motion.

"Exploring the Solar System: Hide and Seek Moon" is an engaging way for early childhood learners to experiment with some of the tools scientists use to study objects that are very, very far away, and

Learners investigate why the Sun and Moon appear the same size in the sky even though the Sun is over 400 times larger in diameter.

In this activity, learners explore in what ways the shape of the land and the pull of gravity influence how water moves over Earth.

This is a lesson plan for an activity in which learners, playing the role of archeologists, use math concepts about number bases to decipher the Dresden Codex, an ancient Mayan document.

In this activity, learners recreate the lunar phases using the frosting from Oreo® cookies and place the phases in order. Round cream cheese crackers can also be used if cookies are not an option.
