Curated OER
Relative Masses
Students investigate relative mass using 8 different items. In this relative masses lesson plan, students discuss as a class John Dalton's atomic theory. They take the masses of the 8 items and record their data. They discuss relative...

Understanding the Mole
Students develop an understanding of the mole and molar masses of elements. In this mole lesson plan, students use beans to find their relative masses and draw parallels to the atomic masses of elements. Students work in teams and each...

Calculating the Number of Sub-Atomic Particles in an Atom
For this atoms worksheet, high schoolers compare sub-atomic particles' position, relative charge, and relative mass. High schoolers define mass numbers and atomic numbers. This worksheet has two graphic organizers and four short answer...
Physics Classroom
The Physics Classroom: Momentum and Collisions: Fish Catch Interactive
Students explore the relative mass of two colliding objects, and determine if that can be used to quickly predict the post-collision speed of the objects? An activity sheet guides learners through the process of determining the rule for...
Physics Classroom
The Physics Classroom: Momentum and Collisions: Exploding Carts Interactive
Students explore different situations where two side-by-side carts on a low-friction track push away from each other and travel in opposite directions. The goal is to investigate the effects on the relative mass.
