Measuring Leverage on a Balance

In this measuring mass worksheet, middle schoolers are given six pictures of objects and they determine the proper metric unit to measure the mass of each. They are given 16 objects and they determine if the measurement of mass should be...

Can you disprove the law of conservation of mass? Pupils observe the teacher weigh each part of a reaction. Then, the teacher weighs the result of the reaction and everyone sees that the products do not equal the reactants. Then they...

Extinction events have happen throughout geologic history, but only five mass extinctions occurred over the last 4.5 billion years. Scholars view fossils from a layer of sediment during an extinction event and observe patterns to draw...

Turn a nighttime toe stubbing into an informative discussion about the properties of matter. An intriguing physical science video encourages learners to use their knowledge of matter and mass to identify a mystery object based on...

Have you ever stretched out a Slinkie so much it wouldn't go back to its original shape? Slinkies, like all springs, follow Hooke's Law. A simulation uses springs and masses to demonstrate kinetic, potential, and thermal energy. It...

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...

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...

Let it snow, let it snow, let it ... thundersnow? Explore the thundersnow phenomenon with a video and lesson as part of the Seasonal Science series. The video describes what causes the unique weather event, explains just how rare these...

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...

A football tackle is just a transfer of momentum, Learners discover the principles of Newton's Third Law by analyzing football tackling. The third lesson in a series of 10 videos shows how the mass and velocity of a defensive player lead...
