It's all Done with Mirrors
Source Institutions
This fun and simple hands-on astronomy activity illustrates the path of light as it reflects off of mirrors and how this is used in telescopes.

How Animals Stay Warm
Source Institutions
In this quick activity, learners explore how blubber protects animals from the cold by making a "blubber mitt." Using cooking shortening, two zip-top sandwich bags, and duct tape, learners simulate bl

Paper Cup Anemometer
Source Institutions
In this meteorological activity, learners get to build their very own anemometer (instrument for measuring wind speed) using a paper cup.

Conductivity: Salty Water
Source Institutions
Water, whether fresh or salty, serves as one of the best electrical conductors on the planet. Does salt effect its conductivity?

Why do Raindrops Sometimes Land Gently and Sometimes Land with a Splat?
Source Institutions
In this activity, learners examine raindrop bottles (prepared ahead of time) to observe in slow motion the behavior of falling droplets and explore concepts such as drag and terminal velocity.

A Crayon Rock Cycle- Metamorphic
Source Institutions
This is part 2 of the three-part "Crayon Rock Cycle" activity and must be done after part 1: Sedimentary Rocks. In this activity, learners explore how metamorphic rocks form.

Earth Atmosphere Composition
Source Institutions
In this activity, learners use rice grains to model the composition of the atmosphere of the Earth today and in 1880. Learners assemble the model while measuring percentages.

Exploring Moisture on the Outside of a Cold Cup
Source Institutions
In this activity, learners explore the relationship between cooling water vapor and condensation. Learners investigate condensation forming on the outside of a cold cup.

Light is Made of Colors
Source Institutions
Learners observe different light sources, outdoors and indoors, using prism glasses (diffraction glasses) and color filters.

Particle Detection
Source Institutions
By tossing, collecting, and sorting beanbags, learners understand how the IBEX spacecraft uses its sensors to detect and map the locations of particle types in the interstellar boundary.

Leaf it to Me
Source Institutions
In this activity, learners observe the effect of transpiration as water is moved from the ground to the atmosphere.

Estuaries
Source Institutions
An estuary is a body of water that is created when freshwater from rivers and streams flows into the saltwater of an ocean.

Cool Tool
Source Institutions
In this activity (on pages 10-17), learners discover how scientists study biodiversity and the health of the environment based on inspection of small areas—a process known as sampling.

Gaming in the Outdoors
Source Institutions
In this set of outdoor games, learners increase their awareness of the outdoor environment by going on a scavenger hunt and an out-of-place hunt.

West Coast Shipwrecks
Source Institutions
In this data activity, learners will explore shipwrecks from four National Marine Sanctuaries on the West Coast of the United States.

Shoebox Dinosaur Dig Site
Source Institutions
In this activity, (on page 6 of the PDF under SciGirls Activity: Dinosaurs) learners participate in a hands-on fossil excavation.

Fast Rusting
Source Institutions
In this activity, learners conduct an experiment to find out if steel wool will weigh more or less when it is burned. Learners will explore the effects of oxidation and rusting on the steel wool.

Indicating Electrolysis
Source Institutions
In this activity, learners build a simple electrolysis device. Then learners use an indicating solution to visualize hydrogen and oxygen molecules in water.

Portable Sundial
Source Institutions
Learners construct one or more of the following kinds of sundials: a shadow plot, a horizontal sundial, and a diptych sundial.

Balloon Rockets
Source Institutions
This is an activity about rockets. Learners will explore how rockets leave Earth's orbit and what it takes to make a launch successful.
