Light Maze
Source Institutions
In this activity, learners will explore light with reflective surfaces. Learners will make predictions and share their observations as they experiment with directing a beam of light.
Bent Toward Science: Refraction
Source Institutions
This is an activity about the behavior of light. Using simple, everyday objects, learners will discover that light moves in straight lines until acted upon by another object.
Pictures From Light
Source Institutions
Did you know that using a lens one can bend light to make pictures of the world? It's true!
Paper Whites
Source Institutions
Learners observe different paper samples under ordinary room light and under a black light to learn some of the chemical differences between different types of paper.
On the Fringe (formerly Bridge Light)
Source Institutions
In this activity, learners trap a thin layer of air between two pieces of Plexiglas to produce rainbow-colored interference patterns.
Up Periscope!
Source Institutions
This activity provides instructions for building a mirrored tube--a smaller and simpler version of a submarine's periscope--that lets you see around corners and over walls.
Shadow Puppets
Source Institutions
In this activity, learners will create their own simple shadow puppets, and experiment with light and shadow while playing with them.
Dirty Oil, Oily Dirt
Source Institutions
In this activity, learners discover how sediment is affected in an oil spill. Learners investigate the differences between heavy and light oil as well as the differences between different sediments.
Measure the Sun's Size
Source Institutions
In this activity, learners make their own pinhole viewer in order to measure the size of the sun.
Light Combinations
Source Institutions
In this activity about magnetism (page 17 of the pdf), learners experiment with magnets, exploring the concept of diamagnetic materials by seeing how a grape reacts to a magnetic field.
Aluminum-Air Battery: Foiled again!
Source Institutions
Construct a simple battery that's able to power a small light or motor out of foil, salt water, and charcoal. A helpful video, produced by the Exploratorium, guides you along on this activity.
Opti-Top
Source Institutions
In this activity, learners will create an optical illusion top. Learners will explore color mixing, physics and design through this activity.
Seeing 3D
Source Institutions
Create 3D glasses and use them to explore color, light and optics. Fool your brain into 'seeing' three dimensions on a flat surface!
Pringles Pinhole Camera
Source Institutions
An ordinary camera has a lens that makes an image on film. In a pinhole camera, a small hole replaces the lens.
Safer with Science-Masks
Source Institutions
Why should we wear masks? Do masks work? Do some masks work better than others? Learners find out in this activity.
Circuit Sense
Source Institutions
In this activity about electricity, learners identify closed and open circuits. First, learners examine and label diagrams of open and closed circuits.
Tasty Buds
Source Institutions
In this activity (1st activity on the page), learners explore their sense of taste and the structure of the tongue by taste-testing various foods.
Our Place in Our Galaxy
Source Institutions
In this fun and simple hands-on astronomy activity, learners construct a model of our place in the Milky Way Galaxy and the distribution of stars, with a quarter and some birdseed.
Does the Moon Rotate?
Source Institutions
This fun and simple hands-on astronomy activity lets learners make 3-dimensional models of the Earth and Moon.
Eye Spy
Source Institutions
This fun activity uses simple materials such as milk cartons and mirrors to introduce the ideas of optics and visual perception.
