How Plants Grow
Source Institutions
In this biology activity (page 3 of the PDF), learners will explore how plants turn sunlight into food through a process called photosynthesis.
Solar Structures
Source Institutions
In this activity, learners explore how the power of the sun can be harnessed to heat and cool a building.
Earth's Energy Cycle: Albedo
Source Institutions
In this activity, learners experiment and observe how the color of materials that cover the Earth affects the amounts of sunlight our planet absorbs.
Leaves: Extracting Pigments
Source Institutions
In this fun, hands-on autumn activity, learners experiment to discover whether the colored substances in leaves can be separated from the leaves.
What is Light?
Source Institutions
In this four-part activity, learners will discover the exciting world of light--the most important form of energy in our world--and be able to identify and describe different types of light.
Understanding Albedo
Source Institutions
In this activity related to climate change, learners examine albedo and the ice albedo feedback effect as it relates to snow, ice, and the likely results of reduced snow and ice cover on global temper
A Degrading Experience
Source Institutions
In this activity on page 27, learners perform an experiment to learn about how different types of marine debris degrade and how weather and sunlight affect the rate of degradation.
What Causes Wind?
Source Institutions
In this sunny day experiment, learners measure and compare how quickly light and dark colored materials absorb heat.
Do Plants Need Light?
Source Institutions
In this food science activity, learners conduct an experiment that demonstrates the importance of light to plants.
What does Color have to do with Cooling?
Source Institutions
In this demonstration/experiment, learners discover that different colors and materials (metals, fabrics, paints) radiate different amounts of energy and therefore, cool at different rates.
Why is the Sky Blue?
Source Institutions
In this activity, learners use a flashlight, a glass of water, and some milk to examine why the sky is blue and sunsets are red.
Equatorial Sundial
Source Institutions
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.
Wonderful Weather
Source Institutions
In this activity, learners conduct three experiments to examine temperature, the different stages of the water cycle, and how convection creates wind.
How does the Atmosphere keep the Earth Warmer?
Source Institutions
In this activity, learners simulate the energy transfer between the earth and space by using the light from a desk lamp desk lamp with an incandescent bulb and a stack of glass plates.
Paper Chromatography with Leaves
Source Institutions
In this activity on page 5 of the PDF (Plants—The Green Machines), learners use chromatography to separate and identify pigments within various leaves.
What Does Life Need to Live?
Source Institutions
In this astrobiology activity (on page 11 of the PDF), learners consider what organisms need in order to live (water, nutrients, and energy).
Illuminating Luminescence
Source Institutions
In this activity, learners compare and contrast different forms of luminescence by observing how chemiluminescence, phosphorescence, and fluorescence produce or emit light.
House Warming
Source Institutions
In this physical sciences activity, learners explore how passive solar design increases energy efficiency.
What's the Angle?
Source Institutions
This activity helps learners understand how the angle of the Sun affects temperatures around the globe.
Light is Made of Colors
Source Institutions
Learners observe different light sources, outdoors and indoors, using prism glasses (diffraction glasses) and color filters.
