The Geophysical Light/Dark Cycle
Source Institutions
This is an activity (located on page 131 of the PDF) related to sleep and circadian rhythms as well as space travel.

Space Weather Action Center
Source Institutions
In this interdisciplinary activity, learners create a Space Weather Action Center (SWAC) to monitor solar storms and develop real SWAC news reports.

Morning Star and Evening Star
Source Institutions
This demonstration activity models how Venus appears from Earth.

Make a Terrarium
Source Institutions
In this activity, learners make a miniature greenhouse or "terrarium" to explore the greenhouse effect.

Using Solar Energy
Source Institutions
In this activity, learners discover how solar energy can be used to heat water.

Modeling the Night Sky
Source Institutions
In this two-part activity, learners explore the Earth and Sun's positions in relation to the constellations of the ecliptic with a small model.

Detect Solar Storms
Source Institutions
In this activity, learners build their own magnetometer using an empty soda bottle, magnets, laser pointer, and household objects.

Scale Model of Sun and Earth
Source Institutions
In this activity, learners explore the relative size of the Sun and Earth as well as the distance between them.

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

Cook with a Solar Oven
Source Institutions
In this activity, learners make their own solar oven to bake s'mores and learn about how solar energy is absorbed on Earth.

The Shadow Knows I
Source Institutions
In this activity, learners will measure the length of their shadow from the Sun and compare it three to four months later.

Sunny Day Painting
Source Institutions
In this activity, learners explore properties of water and watch evaporation happen by "painting" with water in the sun.

Changing Shadows
Source Institutions
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.

Size it Up
Source Institutions
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.

Oil Spot Photometer
Source Institutions
In this math activity related to light, learners assemble a photometer and use it to estimate the power output of the Sun.

Eclipse: How can the little Moon hide the giant Sun?
Source Institutions
In this activity, learners explore how distance can affect the way we perceive the size of an object.
