Dripping Wet or Dry as a Bone?
Learners investigate the concept of humidity by using a dry and wet sponge as a model. They determine a model for 100% humidity, a sponge saturated with water.
Wind Mapping with Bubbles
Source Institutions
Discover the wind's direction using bubbles, a map and a keen eye. Learners blow bubbles and note their general direction on a map, taking readings from different points around a building.
The Scoop on Habitat
Source Institutions
Some aquatic organisms live in open water, while some live in soil at the bottom of a body of water.
Drying It Out
Source Institutions
In this activity, learners investigate and compare the rate of drying in different conditions.
Dry Ice Comet
Source Institutions
In this activity, dry ice and other items are used to construct a demonstration model of a comet that illustrates the comet nucleus, coma, and tails.
Make a Model Caldera
Source Institutions
In this quick activity (page 2 of PDF under GPS: Lava Flow Activity), learners will model how large depressions near the top of a volcano are formed by using an inflating and deflating balloon submerg
Physics in the Sky: Physics on a Plane
Source Institutions
On an airplane trip, learners have an opportunity to investigate the properties of air pressure at different altitudes.
DIY Pasta Rover
Source Institutions
In this activity, learners design and build a NASA rover using raw pasta and candy with a limited imaginary budget.
It's Natural
Source Institutions
This activity introduces learners to Native Americans as people who depended upon nature in the past and continue to emphasize the importance of nature in the present.
Exploring the Universe: Space Guess Quest
Source Institutions
Space Guess Quest is a fun game that encourages participants to identify the many types of objects in space, from human-made spacecraft to nebulas, galaxies, stars, and worlds.
Up, Up and Away with Bottles
Source Institutions
In this activity, learners make water rockets to explore Newton's Third Law of Motion. Learners make the rockets out of plastic bottles and use a bicycle pump to pump them with air.
Foam Tower
Source Institutions
In this activity (page 1 of the PDF under SciGirls Activity: Water Slides), learners will whip up some suds with a cup of water and a tablespoon of dish soap until the bubbles are stiff enough to star
Learning the Land
Source Institutions
In this activity, learners will take a step back and learn the history of the land they live on, and the people who used to live on it.
Map Your World
Source Institutions
In this activity, learners map their world by drawing a plan of their bedroom.
Space Rocks!: A Meteorite Game
Source Institutions
In this board game, learners explore the origins of meteors, meteoroids, and meteorites as well as the their characteristics and importance. They also discover some misconceptions about meteors.
Earth Attractions
Source Institutions
In this activity, learners build and test a compass. Learners work in pairs and pretend they are stuck in the wilderness at night.
Edible Earth
Source Institutions
In this activity, learners make a model of the solid Earth's layers that's good enough to eat! Learners use tasty foodstuffs to simulate Earth's inner core, outer core, mantle, and crust.
Plankton Feeding
Source Institutions
This activity provides a hands-on experience with a scale model, a relatively high viscosity fluid, and feeding behaviors.
Hail Storm House
Source Institutions
In this activity, learners construct hail-proof houses using recycled materials to discuss storm readiness and safety.
CD Air Puck
Source Institutions
In this activity, learners will use a compact disc to build an air puck that can glide across a smooth tabletop. The puck glides with almost no friction on a cushion of air escaping from a balloon.
