Modeling Day and NightAdd to list Details
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.
Hot Equator, Cold PolesAdd to list Details
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.
Why Do Eclipses Happen?Add to list Details
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.
Water Illusions: Refraction & Magnification
Learners demonstrate how water can distort, refract and magnify light.
Earth's Energy Cycle: AlbedoAdd to list Details
In this activity, learners experiment and observe how the color of materials that cover the Earth affects the amounts of sunlight our planet absorbs.
Make a PrismAdd to list Details
In this activity, learners will make their own prism and use a glass of water to separate sunlight into different colors.
Solar Powered Cooking
In this activity, learners make a solar oven. Learners witness the awesome power of the sun to make a yummy treat--a chocolate chip cookie!
Desert Water KeepersAdd to list Details
In this outdoor, sunny day activity, learners experiment with paper leaf models to discover how some desert plants conserve water.
Finding the Right CraterAdd to list Details
This quick demonstration (on page 11 of PDF) allows learners to understand why scientists think water ice could remain frozen in always-dark craters at the poles of the Moon.
Light on Other Planets
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
Toasty WindAdd to list Details
In this quick activity, learners use a toaster to investigate the source for the Earth's wind. Learners hold a pinwheel above a toaster to discover that rising heat causes wind.
The Shadow Knows IIAdd to list Details
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.
Model the Sun and EarthAdd to list Details
In this activity, learners make scale models of the Sun and Earth out of paper mache.
Solar Flare Flip BookAdd to list Details
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.
What Causes Wind?
In this sunny day experiment, learners measure and compare how quickly light and dark colored materials absorb heat.
Make a UV DetectorAdd to list Details
In this activity, learners use tonic water to detect ultraviolet (UV) light from the Sun and explore the concept of fluorescence.
Using a SundialAdd to list Details
In this activity (on page 12 of the PDF), learners make a sundial (shadow clock) appropriate for their geographic location in the northern hemisphere and use it to tell time.
Cooking With the Sun
In this activity, learners build a simple solar oven out of household materials to melt chocolate and marshmallow between graham crackers--known as s'mores.
Reason for the SeasonsAdd to list Details
In this activity (on page 6 of the PDF), learners plot the path of the sun's apparent movement across the sky on two days, with the second day occurring two or three months after the first.
A group of learners models the Sun shining on the Earth. By rotating the Earth, they demonstrate how the Sun only shines on a portion of the Earth at a time.
