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.

DNA Extraction
Source Institutions
In this activity related to plant biotechnology, learners extract DNA from fruit to investigate how it looks and feels.

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

Exploring Products: Nano Sand
Source Institutions
In this activity, learners explore how water behaves differently when it comes in contact with "nano sand" and regular sand.

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

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.

Exploring Tools: Special Microscopes
Source Institutions
In this activity, learners use a flexible magnet as a model for a scanning probe microscope (SPM). They learn that SPMs are an example of a special tool that scientists use to work on the nanoscale.

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.

Jell-O Model of Microfluidics
Source Institutions
This activity uses Jell-O(R) to introduce learners to microfluidics, the flow of fluids through microscopic channels.

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

Gummy Shapes
Source Institutions
In this activity, learners use chemistry to “self-assemble” gummy shapes. Learners discover that self-assembly is a process by which molecules and cells form themselves into functional structures.

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.

Inkjet Printer
Source Institutions
In this activity, learners investigate how inkjet printers produce tiny, precise drops of ink.

Exploring Materials: Thin Films
Source Institutions
In this activity, learners create a colorful bookmark using a super thin layer of nail polish on water. Learners discover that a thin film creates iridescent, rainbow colors.

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.

Spectroscope
Source Institutions
In this activity (posted on March 12, 2011), learners follow the steps to construct a spectroscope, a tool used to analyze light and color.

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.

Making Connections: What You Can Do To Help Stop Global Climate Change
Source Institutions
In this cooperative learning activity, learners visit ten stations and are challenged to think critically about various conservation questions and issues.
