The Center of Mass

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 results,...

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...

I would weigh less on the moon? Send me there, then! On the top of the first page, a cartoon image demonstrates the difference between Earth and the moon. It then goes on to describe weight and mass and provides five practice problems...

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...

Students comrehend that water displacement is a simple way to measure the volume of a solid object. They pour water into a graduated cylinder or measuring cup and its volume is read and recorded. Pupils the volume of an object by...

In this measuring mass worksheet, students 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...

Students find the density of diet soda and regular soda. In this density lesson plan, students measure the mass of a graduated cylinder with 10 different volumes of each soda. They find the mass of the liquid alone and use the volume to...

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...

Explore the center of gravity with your science class as they create a deadfall trap with common materials. They research the concepts of energy conservation and gravitational force before dividing into small groups to create a model of...

Experiment with mass and density as scholars figure out what makes things float or sink. First, they watch a podcast introducing these concepts. Be sure to use the comprehension question to test their understanding. Young scientists...
