In this activity, learners set up an experiment to investigate the effects of hot air on the path of a laser beam.

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.

In this outdoor activity, learners use only their senses to to find the extremes of several environmental variables or physical factors: wind, temperature, light, slope and moisture.

This activity provides an opportunity for learners to observe and examine how carbon dioxide, water, and light produce glucose/starch through a process called photosynthesis.

In this outdoor, winter activity, learners find living green plants under the snow and determine the light and temperature conditions around the plants.

In this activity about color, learners get to explore the process of chromatography. Right before their eyes, they can watch ordinary green and black ink turn into a literal rainbow of colors.

In this activity on page 13 of the PDF, use a special plastic card that has been painted with a chemical that changes color when it is in UV light.

Learners are challenged to discover the relative densities of colored liquids to create a rainbow pattern in a test tube.

Learners investigate one factor affecting reaction rates: temperature. In a darkened room, two identical lightsticks are placed in water -- one in hot water and one in cold water.

Using zebra mussels (Dreissena polymorpha), elodea and an indicator dye, learners study the role of light in photosynthesis.

Learners experiment with water gel crystals, or sodium polyacrylate crystals, which absorb hundreds of times their weight in water. When in pure water, the water gel crystals cannot be seen.

Learners shine the light of a laser pointer through sheets of fabric that all have a different number of threads per inch.

In this activity related to microbes, learners use water drops and hand lenses to begin the exploration of magnification. This activity also introduces learners to the microscope.

In this "Sid the Science Kid" activity, learners set up a simple experiment to find out how sunscreen counteracts the effects of the sun.

In this activity, learners explore how infrared technology is used by engineers to create equipment and systems for a variety of industries.

In this chemistry lab activity, learners model the colors of fireworks by burning metallic solutions in a flame and observing the different colors produced.

In this sunny day experiment, learners measure and compare how quickly light and dark colored materials absorb heat.

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.

In this activity, learners explore how light and dark colored objects absorb the Sun's radiations at different rates.

In this activity on page 13 of the PDF, learners use a laser pointer (with known wavelength of light) to measure the thickness of a human hair.
