Where is the Sun?
Source Institutions
In this activity, learners verify that the Sun appears in a different location at a specific time every day of the year with one exception: on the Equinoxes.
Rainbow Paper
Source Institutions
In this activity, learners will use clear nail polish and the power of chemistry to create paper with a rainbow sheen.
Flashlight Play
Source Institutions
In this activity, young learners will explore light and darkness through flashlight play.
Paper Cover Up
Source Institutions
In this activity on page 11 of the PDF, learners use candle wax to make "invisible" designs that are revealed with watercolor paints.
CD Spinner
Source Institutions
In this activity, learners create a simple “top” from a CD, marble and bottle cap, and use it as a spinning platform for a variety of illusion-generating patterns.
Mix and Match
Source Institutions
In this activity (7th activity on the page), learners use their sense of hearing to find a "sound match." Learners shake containers filled with items like dry seeds, sand, beans, etc.
Amazing Albedo
Source Institutions
In this experiment, learners work in teams to investigate how the color of a surface influences its ability to reflect light and therefore heat.
Newspaper Collage
Source Institutions
In this activity on page 3 of the PDF, learners create a collage by using vinegar to transfer color pictures from a newspaper onto a piece of white paper.
Rotating Light
Source Institutions
In this activity, learners explore what happens when polarized white light passes through a sugar solution.
Bat Echolocation Experiment
Source Institutions
In this activity, learners discover how bats use echolocation to get information about objects in their environment. During the activity, one learner whispers into a tube.
Making a One-Second Timer
Source Institutions
This lab activity has learners create a pendulum with a one-second period.
Matraca
Source Institutions
In this activity, learners create a traditional Mexican noisemaker (a matraca) using cardboard, craft sticks, and a wooden dowel.
Luminol Test
Source Institutions
Learners mix a solution containing luminol and copper with a fake blood solution. A chemical reaction between the luminol solution and fake blood (hydrogen peroxide) show learners a blue glow.
Delta, Delta, Delta
Source Institutions
In this experiment, learners construct an equilateral triangle using graph paper, a pencil, protractor and ruler. They also make a "laser triangle" using a laser pointer and front-silvered mirrors.
Make Maracas
Source Institutions
Make a rattle-like musical instrument! Shake it, hit it, spin it any way you want to!
Reflecting Rainbows: Decorate Your White Walls With Rainbow Colors!
Source Institutions
Like water drops in falling rain, a CD separates white light into all the colors that make it up.
Be a Scanning Probe Microscope
Source Institutions
In this activity, learners investigate Scanning Probe Microscopes (SPM) and then work in teams using a pencil to explore and identify the shape of objects they cannot see, just as SPMs do at the nano
Water Illusions: Refraction & Magnification
Source Institutions
Learners demonstrate how water can distort, refract and magnify light.
Bubble Tray
Source Institutions
In this activity, learners use simple materials to create giant bubbles.
Cylindrical Mirror
Source Institutions
In this activity, learners create a cylindrical mirror to see themselves as others see them.
