Learners explore mass measurement. They complete a diagram of a triple beam balance. Students explore using the triple beam balance to determine the mass of an object. They discuss procedures for using the triple beam balance.

Middle schoolers explore geometry by completing a physics activity on-line. For this mass measurement lesson, pupils define the terms mass, volume, and density and identify their relationship with each other. They complete an on-line...

Learners practice converting metric measurements by completing the activities listed in this lesson. They first practice measuring common objects. They then convert metric measurements using the included worksheet.

Young scholars solve linear equations using two steps. In this algebra instructional activity, students add, subtract, multiply and divide to solve linear equations. They apply concepts of equations to a robot pulling cargo.
