Foam Rocket
Source Institutions
In this activity, learners work in teams build and launch rubberband-powered foam rockets.
Number Sense and Computation: To Half or Half Not
Source Institutions
In this math lesson, learners use slices of bread and geoboards to explore several ways to divide a rectangle in half. Learners also identify equivalent fractions that represent one-half.
Conservation Island
Source Institutions
In this lesson, learners will understand the concepts behind endangered and extinct animals and develop their own conservation plan to save three endangered species.
Energy Audit
Source Institutions
In this lesson, learners will practice graphing and statistically analyzing data.
Pop Can "Hero Engine"
Source Institutions
In this activity, learners build water-propelled engines from soft drink cans.
Mating Game
Source Institutions
In this game (on pages 14-21), learners explore how each human being inherits genetic traits such as eye color.
Low-Tech Water Filter for High-Impact Clean
Source Institutions
In this activity, learners consider the water features they might enjoy at a community park--a pond, brook, water playground (or "sprayground"), or pool--and what happens to the water over time.
Levers at Play
Source Institutions
In this activity, learners consider how a simple machine, a lever, turns a small push or pull (a small force) into a larger--or stronger--push or pull (a larger force).
Ancient Sun Observations
Source Institutions
In this activity, learners make their own Sun tracker to explore how ancient civilizations around the world studied the Sun.
The Orange Game: Routing and Deadlock in Networks
Source Institutions
When a lot of people share one network (such as cars using roads, or messages getting through the Internet), there is the possibility that competing processes will create a “deadlock," or an interrupt
Recycling Paper
Source Institutions
In this crafty chemistry activity (on page 2 of the PDF), learners make their own paper from used paper they may have otherwise thrown away.
Magic Lanterns
Source Institutions
A magic lantern is a light that projects an image onto a screen.
MarsBound!: Mission to the Red Planet
Source Institutions
MarsBound! is an engineering simulation activity in which learners use realistic techniques to plan a mission to Mars.
Beat the Clock: Sorting Networks
Source Institutions
Even fast computers are limited to how quickly they can solve problems. One way to speed things up is to use several computers at once.
Sand Dunes
Source Institutions
This outdoor activity (on page 2 of the PDF under SciGirls Activity: Sand Dunes) is a full inquiry investigation into how the amount of moisture in a sand dune relates to the number of plants growing
Sticky Engineering Challenge
Source Institutions
In this activity, learners explore how engineers work in a team to solve problems.
Global Climate Change and Sea Level Rise
Source Institutions
In this activity, learners practice the steps involved in a scientific investigation while learning why ice formations on land (not those on water) will cause a rise in sea level upon melting.
Clipper Creations
Source Institutions
In this activity, learners create a working model of a nail clipper. This activity helps learners learn the basic principles of simple machines, engineering design and model building.
Interactive Gumball Machine
Source Institutions
In this activity, learners review the history of gumball machines and explore potential and kinetic energy, while working in teams to build a gumball slide.
Aerial Imagery
Source Institutions
This activity (on page 2 of the PDF under SciGirls Activity: Earthquakes) is a full inquiry investigation into aerial imagery.
