Lean, Mean Information Machine: Using a Simple Model to Learn about Chromosomal DNA
Source Institutions
Learners observe a model of a cell and its chromosomal DNA made from a plastic egg and dental floss. Use this model to illustrate how much DNA is held in one cell.

Tiny Tubes
Source Institutions
In this activity, learners make "totally tubular" forms of carbon. Learners use chicken wire to build macro models of carbon nanotubes.

Avalanche
Source Institutions
In this geology activity, learners create a model using a mixture of salt and sand inside a CD case. When the case is tilted or inverted, the mixture dramatically sorts into a layered pattern.

How Do Viruses Recognize a Target Cell?
Source Institutions
This activity demonstrates the specificity of viral vectors for target cells in gene therapy delivery methods using two approaches: 1) STYROFOAM® models demonstrate viral ligand binding to receptor pr
Build Your Own Wind Turbine
Source Institutions
Learners construct an electricity-generating wind turbine out of a plastic bottle.

Hull Engineering
Source Institutions
In this activity, learners explore how the hull shape impacts a ship's performance and stability.

Fan Cart
Source Institutions
If a sailboat is stranded because there is no wind, is it possible to set up a fan on deck and blow wind into the sail to make the boat move?

Jam Jar Jet
Source Institutions
In this activity, learners create a "Jam Jar Jet" based on Francois Reynst's discovery of a pulsejet engine, which uses one opening for both air intake and exhaust.

Modeling Limits to Cell Size
Source Institutions
This investigation provides learners with a hands-on activity that simulates the changing relationship of surface areas-to-volume for a growing cell.

Build Your Own Robot Arm
Source Institutions
In this lesson, learners develop a robot arm using common materials. Learners explore design, construction, and teamwork, as well as materials selection and use.

Gumdrop Dome
Source Institutions
In this activity (located on pages 23-24 of the PDF), learners are introduced to structural engineering and encouraged to practice goal-oriented building.

Catapult
Source Institutions
In this activity, learners construct their own small catapults using simple materials. Learners follow visual instructions to build their launching device.

Bottle Cars
Source Institutions
In this activity, learners explore motion, energy, and electricity by constructing bottle cars that run on motors.

Toilet Model
Source Institutions
In this activity, PVC pipe, plastic water bottles and vinyl tubing are used to make a simple working toilet model. The model shows the role of a siphon in the flushing of a toilet.

Zero-Energy Housing
In this activity, learners investigate passive solar building design with a focus solely on heating.

Wind Turbine Blade Design
Source Institutions
In this activity, learners design, build and test wind turbines. Learners go through the design process and use the scientific method to test important blade variables.
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.

LEGO® Chemical Reactions
Source Institutions
This activity uses LEGO® bricks to represent atoms bonding into molecules and crystals. The lesson plan is for a 2.5 hour workshop (or four 45-minute classes).

Thirsty Candle
Source Institutions
In this activity, learners will explore the dynamics of air pressure by using a candle, a cup, and a dish of water.

Echo Base Bobsleds
Source Institutions
The goal of this activity is to build a miniature bobsled that is either the fastest or the slowest. Learners use recycled materials to design, build, and test their bobsled on a bobsled track.
