In an open-ended design activity, students use everyday materials (milk cartons, water bottles, pencils, straws, candy) to build a small-scale transportation device. They incorporate the use of a wheel and axle, and lever into their...

For thousands of years, navigators have looked to the sky for direction. Today, celestial navigation has simply switched from using natural objects to human-created satellites. A constellation of satellites, called the Global Positioning...

Explore bats' navigation systems by experimenting with echolocation. Approximate an object's distance by analyzing reflected sound waves, measuring the delay in sound and calculating the ratio to the speed of sound.

This lesson helps students to demonstrate the ability to use a light year as a standard of measurement to calculate time and distance from the earth. They will also solve problems based on light years.

In past times, ocean navigators tossed a piece of wood over the side of their ships and noted how long until the ship passed the wood. They used this time measurement and the length of the ship to calculate their speed and estimate how...
