Penny Cup Game
Source Institutions
In this optics activity, learners conduct an experiment to find out why two eyes are better than one!
What's in the Bag?
Source Institutions
In this activity, young learners use their sense of touch rather than sight to identify a mystery object in a bag. Learners take turns acting as "peekers" and "sensers" throughout the game.

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.

How to Extract DNA From Anything Living
Source Institutions
In this genetics activity, learners discover how to extract DNA from green split peas.

Build a Soundscape
Source Institutions
This is a virtual representation of a sound mixer containing pre-looped sounds of animal, insect, and environmental noises.

Chemical Breath
Source Institutions
This is a chemistry lab activity about solutions (page 7 of the PDF). Learners see firsthand how chemicals in a solution can combine to form an entirely different substance.

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.

Moving Molecules!
Source Institutions
In this activity about molecular diffusion (located on page 2 of the PDF under Nanosilver Activity), learners will make predictions and move molecules of iodine through a seemingly solid plastic sandw

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?

A Stand-up Egg
Source Institutions
In this science trick, learners get an egg to stand-up on its long-axis vertical to a table's top.

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

Giant Lens
Source Institutions
In this activity about light and refraction, learners discover how a lens creates an image that hangs in midair.

Musical Coat Hangers
Source Institutions
Discover how sound travels and what materials make better sound conductors. Can you hear better with your fingers in your ears? Find out with a coat hanger and some string!

Test Density with a Supersaturated Solution
Source Institutions
Learners create three solutions with different levels of salinity. They compare the density of these solutions by coloring them and layering them in a clear plastic cup and in a soda bottle.
