Chances Are: OH NO! Look Out Below for a UFO
Source Institutions
In this math lesson (on Page 13), learners predict and simulate the likelihood of an event occurring.
Hot Stuff!: Testing for Carbon Dioxide from Our Own Breath
Learners blow into balloons and collect their breath--carbon dioxide gas (CO2). They then blow the CO2 from the balloon into a solution of acid-base indicator.
Spill Spread
Source Institutions
In this simulation, learners explore how ocean currents spread all kinds of pollution—including oil spills, sewage, pesticides and factory waste—far beyond where the pollution originates.
For the Birds: Environmental Effects on Population
Source Institutions
In this activity, learners will investigate how shorebirds and seabirds are extremely vulnerable to changes in their environment, whether human-induced or otherwise.
Power Play
Source Institutions
In this online game, learners build complicated machines to complete simple tasks. The game starts with a power source on one side of the screen and the task on the other side.
Rocket Pinwheel
Source Institutions
This is an activity about motion, power, air and Newton’s Third Law of Motion, which states that for every action there is an equal and opposite reaction.
Paper Folding: Unfurling Geometric Paper Shapes
Source Institutions
Use geometry, a ruler, and a steady hand to create these amazing unfurling paper folds!
Trip Wire
Source Institutions
In this activity, learners build simple alarms that they can attach to anything, such as a drawer or doorway. This activity introduces learners to electricity, circuits, and currents.
Exploring at the Nanoscale
Source Institutions
This lesson focuses on how nanotechnology has impacted our society and how engineers have learned to explore the world at the nanoscale.
Motor Bird
Source Institutions
In this activity, learners build a bird that flies in place with help from a motor, wire, and some straws.
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.
Paddle Boat
Source Institutions
In this activity, learners build an old-fashioned paddle boat out of simple materials.
Kites
Source Institutions
In this engineering/design activity, learners make a kite, fly it, and then work to improve the design. Learners explore how their kite design variations affect flight.
Take a Plant to Lunch
Source Institutions
Learners make a "menu" of any plants in their lunch for Monday through Friday and draw the plants from their lunch.
A Merry-Go-Round for Dirty Air
Learners build a model of a pollution control device--a cyclone. A cyclone works by whirling the polluted air in a circle and accumulating particles on the edges of the container.
Floating Candles
Source Institutions
In this chemistry activity, learners observe a combustion reaction and deduce the components necessary for the reaction to occur.
Number Systems and Number Theory: Factor Game
Source Institutions
In this math lesson, learners play a game to identify the properties of prime, composite, abundant, deficient and perfect numbers.
Mountain Mash
Source Institutions
Learners model the processes that formed some of Earth's largest mountain ranges: the Himalayas, the Andes, and the Alps.
Valves and Pumps: A Demonstration
Source Institutions
This is a demonstration you can use to show learners how valves and pumps work in concert to move blood through the circulatory system.
File Card Bridges
Source Institutions
With two stacks of books and a few rolls of pennies, build two kinds of bridges--a beam span and an arch span--and see how much weight each of them can hold.
