Use this converter to find equivalent units for a measure. You can convert measures for area, length, weight, temperature, and volume.

On this site, find a variety of materials to help students understand the conservation of matter. Create lessons that allow students to measure and graph quantities that could show even if matter is heated, cooled or combined with other...

Manipulate the mass of a weight and the length of string in this interactive pendulum simulation. Change the speed, friction, and gravity to make the pendulum swing change as measurements are displayed on the screen. Younger students can...

This site provides a great overview of stoichiometry, the part of chemistry that studies amounts of substances that are involved in reactions. Content focuses on what you measure, and includes two examples.

Students work as physicists to understand centripetal acceleration concepts. They also learn about a good robot design and the accelerometer sensor. They also learn about the relationship between centripetal acceleration and centripetal...

In this activity, students use a Dual Range Force Sensor to measure the weight of pennies. They understand the difference between mass and weight. Students also determine the difference in weight of an object on the moon, Mars, Saturn,...

It's difficult at times for younger young scholars to realize that air has mass. Matter is something that has volume (takes up space) and has mass (*can be weighed). Air does take up space, even if we can't see it, and air has weight,...
