Fizzy Nano Challenge
Source Institutions
This lesson focuses on how materials behave differently as their surface area increases.

The Boxes Go Mobile
Source Institutions
Learners display their findings after a study of surface area and volume. They build a mobile to show a commercially available box and a constructed cubical box of the same volume.

Magnetic Spinner & Compass
Source Institutions
Learners use shop tools and various materials to construct a magnetic spinner and a compass.

Tops
Source Institutions
In this activity, learners discover that some things only stand up while they are spinning.

Let's Clone a Mouse, Mouse, Mouse...
Source Institutions
Somatic Cell Nuclear Transfer (SCNT) is a cloning method that involves transferring a nucleus from a somatic cell of the individual to be cloned to an enucleated egg.

Engineering For Earthquakes
Source Institutions
In this design challenge, learners will engineer a structure and see if it can survive an earthquake they create.

Our Sense of Sight: Color Vision
Source Institutions
In this activity, learners investigate color vision as well as plan and conduct their own experiments.

Two Washers
Source Institutions
In this activity, learners create a mind and math puzzle that requires a three-dimensional solution.

Pulleys
Source Institutions
In this activity, learners build inexpensive pulley assemblies from pulley wheels used for sliding screen door replacement or from clothesline spreaders.

Don't Crack Humpty
Source Institutions
Groups of learners are provided with a generic car base and an egg. Their mission: design a device/enclosure to protect the egg on or in the car as it rolls down a ramp with increasing slopes.

Matraca
Source Institutions
In this activity, learners create a traditional Mexican noisemaker (a matraca) using cardboard, craft sticks, and a wooden dowel.

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.

Zig Zag Bopper
Source Institutions
In this activity, learners build a machine made of craft sticks to multiply the levering motion of their hands and create a device that bends and extends.

Solar Structures
Source Institutions
In this activity, learners explore how the power of the sun can be harnessed to heat and cool a building.

Working with Wind Energy
Source Institutions
In this activity, learners explore how wind energy can be generated on both a large and small scale.

Plugged in to CO2
Source Institutions
In this activity, learners investigate various appliances and electronics, discovering how much energy each uses and how much carbon dioxide (CO2) is released to produce that energy.

Landing the Rover
Source Institutions
In this team design challenge (page 19-24 of PDF), learners "land" a model Lunar Rover in a model Landing Pod (both previously built in activities #3 and #4 in PDF).

Toxic Popcorn Design Challenge
Source Institutions
In this activity, learners explore the engineering design process (EDP)—the process engineers use to solve design challenges.

Engineered Music
Source Institutions
In this activity, learners explore how musical instruments are engineered.

Be a Scanning Probe Microscope
Source Institutions
In this activity, learners investigate Scanning Probe Microscopes (SPM) and then work in teams using a pencil to explore and identify the shape of objects they cannot see, just as SPMs do at the nano
