[Free Registration/Login may be required to access all resource tools.] Students investigate and analyze characteristics of waves, including velocity, and calculate the relationship between wave speed, frequency, and wavelength.

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...

Student groups are provided with a generic car base on which to design a device/enclosure to protect an egg as it rolls down a ramp at increasing slopes. During this activity, student teams design, build and test their prototype...

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...

Weigh five little creatures on a metric scale, and subtract to find the mass to the hundredths place for each. A timer calculates your speed of computation.

Weigh five little creatures on a metric scale, and add to find their total mass to the hundredths place as each one joins the group. A timer calculates your speed of computation.

Students measure the angles of refraction of laser light traveling through gelatin, then plot their data to calculate the gelatin's index of refraction.

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 this section of the textbook learn how to define and calculate flow rate. Also learn the differences and similarities between flow rate and fluid velocity. Section also relates flow rate to processes in the body like calculating flow...

Examine how fuel use affects the mass of different planes during flight. This lesson teaches students how to determine the per person fuel cost of a transatlantic flight for seven airplanes, and display the results on a bar graph. Three...

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...

In this instructional activity, students are introduced to both potential energy and kinetic energy as forms of mechanical energy. A hands-on activity demonstrates how potential energy can change into kinetic energy by swinging a...
