Build a stereoscopic microscope
Why build a microscope? The following is a guide on how to build a stereoscopic microscope. This guide allows you to assemble, at a relatively low cost, an instrument that is useful for observing natural objects such as insects, plants, minerals, fossils and flowers.

Difficulty: High school

Build your very own hovercraft!
This interesting experiment shows you how to build a simple hovercraft that can lift several adults!

Difficulty: High school

Compare the strengths of different types of bridges
The purpose of this experiment was to determine whether suspension bridges or cable -stayed bridges would support the most mass.

Difficulty: Elementary school

Construct a model of a magnetically levitated train
I'm a science hobbyist and occasional exhibit designer for science museums. The devices shown here were part of a prototype "room-temperature superconductive table" which never made it to a museum. I thought I'd place it here so students and hobbyists could experiment with this strange maglev effect.

Demonstrate how the light from a Light Emitting Diode can be modulated by using sound
This project can amplitude modulate the light being emitted from an LED using the 8 ohm earphone output from a small radio or amplifier. For demonstrating, it is very convenient to use a small radio to supply the audio signal.

Difficulty: High school

Demonstrate the strength of a suspension bridge using egg shells
Ever wonder why igloos are dome shaped and not square? Ever been amazed at how a suspension bridge can hold the weight of hundreds of passing cars with little or no apparent support underneath it? This experiment demonstrates how arches are used in architecture not only for aesthetic appeal but for a very useful and needed purpose...

Difficulty: Elementary school

Do sound barriers reduce noise? If so, what types of barrier is most effective?
The purpose of this experiment was to determine if a sound barrier does reduce noise, and which type of barrier is the most effective in reducing highway traffic noise.

Difficulty: Middle school

Does the particle size of sand used to make bricks matter?
The purpose of this experiment was to determine which size of the sand particles used to make bricks would be the strongest.

Difficulty: Elementary school

How can you build a toy car using mousetraps?
Here's some general ideas and also some web sites to help you with ideas. These projects are really fun and easy! And you'll be amazed at the different types of cars you can build or buy out there!

Difficulty: Elementary school

How to build a flashlight using Light Emitting Diodes (LEDs)
This cool astronomer's LED flashlight is really two flashlights in one. There are two power switches, each controlling an LED. An LED is a light emitting diode, which is an electronic device that requires very little current to run, so the batteries last a very long time. Also, LED's do not burn out.
