Light Waves: Grades 6-8
Explore the behavior of light with different materials. Collaborative groups determine whether certain materials absorb, reflect, diffract, or transmit light waves. They then measure the angle of incidence and angle of reflection.

Shadows & Light, Science & Puppetry
Lights, shadows, action, and inquiry await your artistic scientists. They explore the way light travels, absorbs, reflects, and transmits through shadow play. They create folktale-inspired shadow puppets, explore the science of light,...
Science 4 Inquiry
Trick or Science: Catching the Light
Your class might be surprised to learn that mirrors have been around since the first century AD! Young scientists explore reflection and refraction of light through a series of challenges. They use this knowledge to design their own...

Build a Light Detector Inspired by Space Communications
Data can travel on light waves ... who knew!?! Pupils explore the idea of using light waves to transmit data through space. They then build their own boards that detect a specific wavelength of light.
Exploratorium
Blue Sky
Use a container full of water as a prism and show that as light is bent, the individual colors from different wavelengths become visible. This explains why the sky appears to be blue midday, and why as the sun nears the horizon, it looks...
Baylor College
Rainbow in the Room
Uncover the science behind the beautiful phenomena of rainbows with a simple demonstration. Shine light through different-sized containers of water as young scientists learn that rainbows occur when visible light is split up into its...

Measuring and Protecting Skin
Several subjects are addressed within the context of a science lesson about the sun's ultraviolet rays. Elementary earth scientists consider protection of the skin with sunscreens (health), estimating and measuring surface area or an...

Shedding a "Little" Light on Cancer Surgery
Many types of cancer treatments now depend on nanotechnology—a big "little" discovery. Scholars begin by removing "malignant" tissue from simulated brains, one using fluorescent markers thanks to nanotechnology and one without. This...
Curated OER
Wavelengths of Light
Explore physical science by participating in a visual spectrum experiments. Budding scientists identify the colors in the color spectrum and view the colors in class by utilizing cellophane, flash lights, and other arts and crafts...
Curated OER
Color
An interesting set of details about the light spectrum, these slides explain how objects reflect and absorb light to affect how they appear to the human eye. The differences in mixing lights or pigments is explained and some everyday...

Waves: Sound and Light
A few definitions related to waves open this slide show. Note that the information only covers light waves even though the title mentions sound. Correct the title before using this resource. Another mention is a set of photos of a class...

Do Plants Need Light?
Turn your classroom into a greenhouse with a lesson on plant growth. First, investigate the different parts of seeds, identifying the seed coat, cotyledon, and embryo. Then plant the seeds and watch them grow! Measure the new plants...
Cornell University
Diffraction Demystified
Study diffraction patterns using CDs and DVDs! Scholars measure the diffraction patterns of a light wave as it hits a CD or DVD. Using the information, they can measure the distance between the tracks.

Designing a Spectroscopy Mission
In this mind-bending activity, young engineers explore this question of whether or not light actually bends. Using holographic diffraction gratings, groups design and build a spectrograph. The groups then move on research a problem...

What things let Light Pass Through?
Second graders classify objects according to how well light can pass through them and predict how well objects will transmit light. They experiment with objects to verify predictions while collecting, recording, and interpreting data...

science: Light Up the Ocean
students investigate light levels under the ocean by conducting several simulations. After creating solutions representing seawater, they shine a light sensor on it to discover how light diffuses and is absorbed by the impurities in the...
National Nanotechnology Infrastructure Network
Jell-O® Waveguide and Power Loss
Jell-O® can help model the transmission of light through fiber optic cables. Young scientists use the jiggly dessert to make a waveguide to transmit a laser beam from one point to another. Their models help them learn the function of...

First You See It, Then You Hear It
Light and sound go hand in hand. Pupils set up a system that will emit sound when a laser is directed at a photodiode. Various objects, such as a comb and talcum powder, allow for modulation of the laser beam. Individuals also...
Discovery Education
Through the Looking Glass
Turning white light into colors only takes a little scientific know how! Young scholars create their own spectroscope in a hands-on activity exploring the properties of light. Using a diffraction grating, they discover how white light...

Laser Challenge
Help your class become laser focused on the connection between sound and light. Scholars set up mirrors to bend and direct lasers that are connected to a music source. Music should start playing when the laser hits the photoresistor.
