Rocking the Boat

Lead your class on an exploration as they locate the center of mass in several oddly shaped two-dimensional objects they create from their imaginations. Pupils also determine the location of the center of mass in three-dimensional...

Scholars review prior knowledge before completing a hands-on simulation of the rock cycle. They write stories or songs summarizing their simulations to demonstrate mastery.

It's better to burn out than fade away! Viewers experience the birth of neutron stars and supernovae in a video that explains the life cycle of high mass stars. Learners see the conditions needed to produce these events, as well as...

Sal builds on the previous video which shows students how to calculate the mass composition of a compound from its empirical formula. This problem uses the elements Hydrogen, Oxygen, and Sulfur. The process requires quite a bit of...

Have some physical science fun when studying the center of gravity or center of mass. Simply have balancing artists stand a dowel on one finger and keep it from falling over! A lump of clay is added and moved up along the dowel over a...

How can a teeter-totter balance when the two people are different sizes? Show classes how this works through a simulation. Scholars play with a teeter-totter to show how different masses and their placement affect balance. Once they have...

Time is growing short. Teams work together to identify physical properties of rocks in order to determine the properties that would best suit their cavern shelter design.

A simple activity goes a long way in demonstrating the property of porosity to your rock hounds. They will mass a specimen of dry sandstone and then soak it in a pre-measured amount of water. After seven minutes, they once again measure...

This short video simply explains the Conservation of Mass with graphics that show the atoms being conserved in pictures of balanced equations. The connection between mass and energy is explained and Einstein's energy equation is mentioned.

What better way is there to introduce conservation of mass than a few simple experiments? Young chemists conduct two chemical reactions, take the masses of reactants and products, then compare their results to determine...
