Soap Bubble Shapes
Source Institutions
Learners explore three-dimensional geometric frames including cubes and tetrahedrons, as they create bubble wands with pipe cleaners and drinking straws.
Our Sense of Sight: Color Vision
Source Institutions
In this activity, learners investigate color vision as well as plan and conduct their own experiments.
Spherical Reflections
Source Institutions
In this art meets science activity, learners pack silver, ball-shaped ornaments in a single layer in a box to create an array of spherical reflectors.
The Liquid Rainbow
Source Institutions
Learners are challenged to discover the relative densities of colored liquids to create a rainbow pattern in a test tube.
Super Sounding Drum
Source Institutions
In this activity, learners construct drums out of everyday containers (like bowls or food containers) and shrink wrap. Learners use a hair dryer to affix and tighten the shrink wrap to the container.
Beam Me Up!
Source Institutions
This is a quick activity (on page 2 of the PDF under Stained Glass Activity) about the "Tyndall effect," the scattering of visible light when it hits very small dispersed particles.
Shake it up with Seismographs!
Source Institutions
In this activity, learners explore the engineering behind seismographs and how technology has improved accurate recording of earthquakes.
Audio Boggle: Make a Sound Track
Source Institutions
Audio Boggle is an activity that lets you listen to a track (that you make yourself) and see what you can hear!
First Impressions
Source Institutions
Learners experiment with a commercial photo-sensitive paper (Sunprint® or NaturePrint® paper). They place opaque and clear objects on the paper and expose it to bright light, observing the results.
Speak to Me
Source Institutions
In this activity, learners will create a speaker using a paper cup, magnet, and enameled wire. Also included in this activity is a Mr.
See the Light
Source Institutions
In this three-part activity, learners conduct simple experiments to see how light refracts and reflects, and how colors of light affect what we see.
Diffraction
Source Institutions
In this optics activity, demonstrate diffraction using a candle or a small bright flashlight bulb and a slide made with two pencils.
Double Dutch Distractions
Source Institutions
This activity (page 2 of the PDF under SciGirls Activity: Double Dutch) is a full inquiry investigation into whether hearing or seeing has a bigger effect on jump rope performance.
See the World Through Color-Filtering Lenses
Source Institutions
In this activity, learners examine how colored lenses act like filters and absorb all colors of light except for the color of the lenses.
Invisible Sunblock
Source Institutions
In this activity, learners find out why some mineral sunblock rubs in clear. Learners compare nano and non-nano sunblocks and discover how particle size affects visibility.
Glowing Pickle
Source Institutions
In this activity, high voltage is applied across a pickle to emit a yellow glow. This activity should only be conducted by skilled adults and is best suited as a demonstration.
Changing Colors
Source Institutions
Learners experiment with a commercially available liquid-crystal coaster. They warm the material with their hands for varying lengths of time and observe the changing colors that result.
Corner Reflector
Source Institutions
In this optics/mathematics activity, learners use two hinged mirrors to create a kaleidoscope that shows multiple images of an object.
Camera Projector
Source Institutions
In this activity (posted on March 14, 2011), learners follow the steps to construct a camera projector to explore lenses and refraction.
Convection Current
Source Institutions
In this activity, learners make their own heat waves in an aquarium.
