The Pull of the Planets
Source Institutions
In this activity, learners model the gravitational fields of planets on a flexible surface.

Space Stations: Sponge Spool Spine
Source Institutions
In this activity, learners simulate what happens to a human spine in space by making Sponge Spool Spines (alternating sponge pieces and spools threaded on a pipe cleaner).

Fossils: Observing, Making and Learning
Source Institutions
In this activity, learners explore how casts of fossilized bones are created and used to learn about dinosaurs. Learners make observations, draw diagrams and share their findings.

Why Doesn’t the Ocean Freeze?
Source Institutions
In this activity, learners explore how salt water freezes in comparison to fresh water.

Seismic Slinky!
Source Institutions
Did you know that a Slinky makes a handy model of earthquake waves?

Erosion and Floods
Source Institutions
In this activity, learners create models of erosion and floods and learn to recognize both in their environment.

Make a Dinosaur Model
Source Institutions
In this activity, learners explore dinosaur skeletons, anatomy, and locomotion. Learners compare and contrast dinosaur skeletons and drawings.

Make a Balloon-powered Nanorover
Source Institutions
In this activity, learners build a nanorover model using styrofoam meat trays and a balloon.

Wetlands
Source Institutions
Learners create a model of a wetland to observe how it absorbs and filters water from the environment.

Morning Star and Evening Star
Source Institutions
This demonstration activity models how Venus appears from Earth.

Rooftop Gardens
How does a green roof, or roof covered by plants, affect the temperature of the inside and outside of a building? Learners design and build houses to find out the answer.

Jiggly Jupiter
Source Institutions
In this activity, learners build edible models of Jupiter and Earth to compare their sizes and illustrate the planets' internal layers.

Catch the Wind
Source Institutions
In this weather activity (page 1 of the PDF), learners will construct their very own anemometer to measure wind speed.

3...2...1 Puff!
Source Institutions
In this activity, learners build small indoor paper rockets, determine their flight stability, and launch them by blowing air through a drinking straw.

Stream Table
Source Institutions
In this activity, learners use aluminum trays and wooden blocks to form stream tables to investigate river formations in two different landscape scenarios.

Zero-Energy Housing
In this activity, learners investigate passive solar building design with a focus solely on heating.

Solar System Bead Distance
Source Institutions
In this astronomy activity, learners create a model of the solar system using beads and string.

As the Rotor Turns: Wind Power and You
Source Institutions
In this engineering activity, learners will get acquainted with the basics of wind energy and power production by fabricating and testing various blade designs for table-top windmills constructed from

Mars from Above: Carving Channels
Source Institutions
In this activity, learners create channel features with flowing water, comparing their observations to real images of Mars and Earth taken by satellites/orbiters.

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.
