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.

DNA Nanotechnology
Source Institutions
In this activity, learners explore deoxyribonucleic acid (DNA), a nanoscale structure that occurs in nature.

Infant Moon: Moon Mix!
Source Institutions
In this activity, learners investigate the Moon's infancy and model how an ocean of molten rock (magma) helped shape the Moon that we see today.

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

Altered Reality
Source Institutions
In this activity, learners discover that the human brain is highly adaptable. Learners try to toss beanbags at a target while wearing prism goggles.

Mapping Sea Level Rise
Source Institutions
In this activity related to climate change, learners create and explore topographical maps as a means of studying sea level rise.

Recipe for a Moon
Source Institutions
In this activity, learners discover that the Moon, like Earth, is made up of layers of different materials. Learners work in teams to make models of the interiors of the Moon and Earth.

Let's Make a Supernova!
Source Institutions
This fun and simple hands-on astronomy activity lets learners explore what happens when a star explodes.

Exploring the Ocean with Robots
Source Institutions
In this activity, learners are introduced to robotic submarines called gliders. Learners make “gliders” from plastic syringes and compare these to Cartesian bottles and plastic bubbles.

Gravestone Weathering
Source Institutions
In this activity (located on pages 9-14 of PDF), learners visit a cemetery to examine the distinguishing characteristics of rock weathering.

Exploring Materials: Ferrofluid
Source Institutions
In this activity, learners discover that a material can act differently when it's nanometer-sized.

Achieving Orbit
Source Institutions
In this Engineering Design Challenge activity, learners will use balloons to investigate how a multi-stage rocket, like that used in the Interstellar Boundary Explorer (IBEX) mission, can propel a sat

Reflections
Source Institutions
In this activity, learners play a game and use pattern blocks to explore mirror images and reflection.

Density Rainbow and the Great Viscosity Race
Learners conduct two activities to investigate two properties of liquids: density and viscosity. In a clear container, learners stack 7 different liquids which will layer according to their density.

Caller ID: The Frog - and Toad! - Mating Game
Source Institutions
This activity is a sensory experience that recreates the sounds of a pond at night.

Corals and Chemistry
Source Institutions
In this activity, learners investigate how increased carbon dioxide (CO2) emissions from the burning of fossil fuels is changing the acidity (pH) of the ocean and affecting coral reefs and other marin

Weather Stations: Phase Change
Source Institutions
In this activity, learners observe the water cycle in action! Water vapor in a tumbler condenses on chilled aluminum foil — producing the liquid form of water familiar to us as rain and dew.

Trash Traits
Source Institutions
In this activity on page 24, learners perform experiments to examine whether or not trash can float, blow around, or wash away.

Toasty Wind
Source Institutions
In this quick activity, learners use a toaster to investigate the source for the Earth's wind. Learners hold a pinwheel above a toaster to discover that rising heat causes wind.

Construction Technologies: Construct the Strongest Bridge
Source Institutions
Learners work in pairs to create three simple types of bridges, a beam bridge, an arch bridge, and a suspension bridge.
