Do Plants Need Light?
Source Institutions
In this food science activity, learners conduct an experiment that demonstrates the importance of light to plants.
Laser Lissajous: Binder Clip Version
Source Institutions
In this activity, learners use a laser pointer and two small rotating mirrors to create a variety of fascinating patterns, which can be easily and dramatically projected on a wall or screen.
Make a UV Detector
Source Institutions
In this activity, learners use tonic water to detect ultraviolet (UV) light from the Sun and explore the concept of fluorescence.
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.
Stereo Hanger
Source Institutions
In this activity, learners investigate sound wave science, in stereo! Learners construct a "stereo" out of a metal coat hanger and piece of string to explore sound vibrations.
Standing in the Shadow of Earth
Source Institutions
This fun and simple hands-on astronomy activity demonstrates the shadow of the Earth as it rises as a dark blue shadow above the eastern horizon.
Penny Cup Game
Source Institutions
In this optics activity, learners conduct an experiment to find out why two eyes are better than one!
Glass and Mirrors: An Inside Look at Telescopes
Source Institutions
This hands-on astronomy activity allows you to create a “cutaway” telescope to clearly show how reflector and refractor telescopes work.
Night Lights
Source Institutions
In this activity, learners create night lights using a plastic cup, programmable PICO Cricket, tri-color LED, and sensor.
Build a Soundscape
Source Institutions
This is a virtual representation of a sound mixer containing pre-looped sounds of animal, insect, and environmental noises.
Our Sense of Sight: Eye Anatomy and Function
Source Institutions
In this activity, learners investigate the sense of sight and develop and conduct their own experiments.
Peripheral Vision
Source Institutions
In this optics activity, learners conduct an experiment to explore peripheral vision. Learners collect data about their ability to see shapes, colors, or letters using their peripheral vision.
Magnification vs. Resolution: Can you see the flag on the Moon?
Source Institutions
This fun and simple hands-on astronomy activity lets learners explore the difference between telescope magnification and resolution.
Shape Stamping
Source Institutions
In this activity, learners will explore two-dimensional shapes that are found in three-dimensional shapes. Learners will explore geometry, design, color and tool use through this activity.
Persistence of Vision
Source Institutions
If you had a long tube with a 5 millimeter wide slit, would you see the entire Golden Gate Bridge?
See the Light
Source Institutions
Learners mix a solution of luminol with hydrogen peroxide to produce a reaction that gives off blue light.
Lateral Inhibition
Source Institutions
Which one of your eyes are dominant? Do they act independently or are they equally "in control?" This activity explores how your eyes work (or don't work) together.
Colorblind Dogs
Source Institutions
This activity (on page 2 of the PDF under SciGirls Activity: Colorblind Dogs) is a full inquiry investigation into dogs' ability (or inability) to see color.
Disappearing Glass Rods
Source Institutions
In this optics activity, learners discover how they can make glass objects "disappear." Learners submerge glass objects like stirring rods into a beaker of Wesson™ oil to explore how the principles of
