Circuit Game
Source Institutions
In this activity, learners build a game that tests their steadiness. Learners construct the game board by setting up an electrical circuit and a wand.
Attract a Fish
Source Institutions
This outdoor activity/field trip requires a place where minnows swim, such as a local pond or brook.
Carousel Pump
Source Institutions
In this activity, learners build a carousel toy that spins when pushed down.
Excavating and Mapping Under Water
Source Institutions
In this archaeology activity, learners consider ways in which excavating an underwater site is different from excavating a terrestrial site.
Our Sense of Sight: Color Vision
Source Institutions
In this activity, learners investigate color vision as well as plan and conduct their own experiments.
Currently Working: Testing Conductivity
Source Institutions
Visitors test solutions of water, sugar, salt, and hydrochloric acid and the solids salt and sugar. They clip leads from the hand generator to wires immersed in each substance.
Fragile Waters
Source Institutions
In this activity (on pages 18-29) learners explore the impact of the March 24, 1989 oil spill in Alaska caused by the Exxon Valdez tanker.
Toxic Popcorn Design Challenge
Source Institutions
In this activity, learners explore the engineering design process (EDP)—the process engineers use to solve design challenges.
Shipping for Survival
Source Institutions
In this activity, learners explore how packaging engineers develop customized shipping and packaging containers to meet the needs of many different industries.
Mold Growth
Source Institutions
In this activity learners observe mold growth on different types of bread by measuring and recording the growth rate.
Clean Water: Is It Drinkable?
Source Institutions
In this activity, learners simulate nature's water filtration system by devising a system that will filter out both visible and invisible pollutants from water.
Crank It Up
Source Institutions
In this engineering activity, learners explore simple machines and then build cardboard automata using cams.
Playing with Parachutes
Source Institutions
In this activity, learners explore how parachutes are used to slow down moving objects. Learners work in teams of "engineers" to design and build their own parachutes out of everyday items.
Electric Highway
Source Institutions
In this design challenge activity, learners design and build a circuit: an "electric highway" that connects a battery and buzzer at least three feet apart using four types of materials.
Clay Exploration
Source Institutions
In this activity, learners explore the possibilities of clay as a natural material.
Shake it up with Seismographs!
Source Institutions
In this activity, learners explore the engineering behind seismographs and how technology has improved accurate recording of earthquakes.
Magnetic Marble Run
Source Institutions
Learners explore magnetism and motion as they build a simple marble run. Learners test different arrangements of plastic and cardboard tubes, bottles, and cups on a magnetic board.
Build a Big Wheel
Source Institutions
In this activity, learners explore how engineers have developed big wheels or Ferris wheels.
Electric Messages: Then and Now
Source Institutions
In this activity, learners explore electronic communication, the Morse Code system, and advances all the way through text messaging. Learners build a simple circuit, send messages to one another.
Ship the Chip
Source Institutions
In this activity, learners explore engineering package designs that meet the needs of safely shipping a product.
