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.
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.
Sound Dampeners
Source Institutions
In this activity, learners will experiment with water- and air-filled balloons as a way of dampening sound before it reaches their ears.
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.
Exploring Shadows
Source Institutions
This activity guide features three related explorations to help learners ages 3-6 investigate shadows via the following science concepts: A shadow is made when an object blocks the light; you can chan
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.
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.
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.
Self-Portrait Silhouettes: Activity 2
Source Institutions
In this activity, learners make a photographic image—without a camera!
Double Horn
Source Institutions
In this activity, learners explore sound by constructing their very own instruments using PVC pipes, soda bottles, and a straw.
Do Plants Need Light?
Source Institutions
In this food science activity, learners conduct an experiment that demonstrates the importance of light to plants.
