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.
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.
Water Illusions: Refraction & Magnification
Source Institutions
Learners demonstrate how water can distort, refract and magnify light.
Earth's Energy Cycle: Albedo
Source Institutions
In this activity, learners experiment and observe how the color of materials that cover the Earth affects the amounts of sunlight our planet absorbs.
Introduction to the New Chain Gang
Source Institutions
In this activity, learners use pop-beads to understand the characteristics and properties of polymer chains.
Two Lenses in One
Source Institutions
In this activity about light, learners explore how water can refract light and change the way they see things.
Exploring Earth: Investigating Clouds
Source Institutions
“Exploring Earth: Investigating Clouds” is a hands-on activity in which visitors create a cloud in a bottle and explore it with laser light.
Exploring the Nanoworld with LEGO Bricks: Probing the Structure of Materials at the Nanoscale
Source Institutions
In this activity (pages 17-31), learners are introduced to techniques that are used to determine the structures of solid materials.
Critical Angle
Source Institutions
In this optics activity, learners examine how a transparent material such as glass or water can actually reflect light better than any mirror.
Black Magic (Color Chromatography)
Source Institutions
With a coffee filter, a black marker, and a cup of water, discover the secret colors hidden in black ink.
Understanding Albedo
Source Institutions
In this activity related to climate change, learners examine albedo and the ice albedo feedback effect as it relates to snow, ice, and the likely results of reduced snow and ice cover on global temper
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.
Playtime Paint
Source Institutions
In this activity on page 9 of the PDF, learners make their own paint using chalk as a pigment and glue and water as binders. This activity introduces learners to special mixtures called suspensions.
Convection Current
Source Institutions
In this activity, learners make their own heat waves in an aquarium.
Try Your Hand at Nano
Source Institutions
This lesson focuses on two simple activities that younger learners can do to gain an appreciation of nanotechnology. First, learners measure their hands in nanometers.
Why is the Sky Blue?
Source Institutions
In this activity, learners use a flashlight, a glass of water, and some milk to examine why the sky is blue and sunsets are red.
Wonderful Weather
Source Institutions
In this activity, learners conduct three experiments to examine temperature, the different stages of the water cycle, and how convection creates wind.
Investigating Ice Worlds
Source Institutions
In this activity about the solar system, learners use various light sources to examine ice with different components to understand how NASA studies planets and moons from space.
Disappearing Crystals
Source Institutions
Learners experiment with water gel crystals, or sodium polyacrylate crystals, which absorb hundreds of times their weight in water. When in pure water, the water gel crystals cannot be seen.
Paper Chromatography with Leaves
Source Institutions
In this activity on page 5 of the PDF (Plants—The Green Machines), learners use chromatography to separate and identify pigments within various leaves.
