Weight A Minute

Enhance your states of matter lessons with a hands-on science investigation that compares six different balls' color, texture, size, weight, ability to bounce, and buoyancy. 

The density of the huge planet of Saturn is 0.7 g/cm3, which means it could float in water! In the second part of 22, science pupils explore the size and order of the planets. They then calculate weight and/or gravity and density of...

Students use graph paper to construct a graph and determine the slope of a straight line. They determine the weight (mass) of paper clips with a pan balance. Pupils weigh an unknown number of paper clips, and to interpret the graph to...

Aspiring aeronautical engineers demonstrate different forces as they construct and test paper airplanes. This lesson plan links you to a website that models the most effective paper airplane design, an animation describing the forces...

Students determine that some liquids are able to evaporate more readily than others. They create a balance using cups and a ruler to determine which end of a strip dipped in alcohol or water evaporates the fastest, hence loses the most...

Too much material will weigh you down. The sixth segment in a series of 22 highlights how weight affects a plane. Pupils learn that engineers take the properties of materials, including weight, when designing something. 

Students explore their weight on other planets. In this science lesson, students view a presentation about the other planets and complete a worksheet in which they make predictions about their weight on the moon and other planets.

Students are taught that the metric system is a decimal system of weights and measures based on the meter for length, the kilogram for weight, and the liter for volume. They research how to convert from imperial units of measure to the...

Can your class solve the problem presented in the Chinese folktale, "Weighing the Elephant?" Read your class the description before having them attempt to solve the problem. After they've come up with an answer (or attempted to!), finish...

Students create their own balance to determine a difference in the weight (and composition) of cents made in different years.
