Teach the masses about the metric system with this hands-on measurement lesson. Given a fruit or vegetable, learners estimate, measure, and convert its mass using the metric units gram and kilogram.

How do you teach a student with visual impairments about the conservation of mass? You use tactile models that represent the theoretical concept. Baking soda and vinegar are used to add gas to a deflated balloon. Learners will feel the...

Why do you weigh more in space? Each individual in your class explores this question and others as they determine the mass and weight of different objects using two types of scales. They perform conversions and discuss their...

Not only do future engineers learn the difference between accuracy and precision, they also get some hands-on experience using different measuring tools. 

Will the block float? Pupils take measurements to calculate the volume of various blocks of different materials. Using a scale, they determine the mass of each block and then calculate their densities. Scholars finish by ranking the...

Stop and drop what is in your hand! Pupils investigate how form effects drag in the 12th part of a 22-part unit on aviation. Groups create equally weighted objects and determine which one falls the fastest by collecting data.

Adjust the melting time of ice without varying the temperature! Learners experiment with different materials to decide how the materials affect the rate an ice cube melts. They then connect their findings to the conductivity of each...

Students learn about the concept of pushing, as well as the relationship between force and mass. Students practice measurement skills using pan scales and rulers to make predictions about mass and distance. A LEGO MINDSTORMS NXT robot is...

This activity can be used to explore forces acting on an object, to practice graphing experimental data, and/or to introduce the algebra concepts of slope and intercept of a line. A wooden 2x4 beam is set on top of two scales. Students...
