A Mass of Pennies
Learners estimate and determine the number of cents (pennies) that are needed to equal the mass of a variety of common objects. They develop a process for measuring and explore concepts related to units of measurement.

Conservation of Mass
How do you teach a student with visual impairments about the conservation of mass? You use tactile models that represent the theoretical concept. Baking soda and vinegar are used to add gas to a deflated balloon. Learners will feel the...

Mass vs. Weight
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,...

Making It Balance
Students listen to story, "The 100-Pound Problem," compare their weight with character in story, and weigh different classroom items using nonstandard units and standard units. They experiment with different items that can make scale...

Mass and Weight in the Metric System
Students weigh and record the mass of various objects, and then compare the weights of objects by holding gram weights in one hand and the object in the other hand.

Chemical Reactions
Investigate the Law of Conservation of Mass through a lab exploration. Individuals combine materials to initiate chemical reactions. They monitor for signs of reactions and measure the masses before and after the reactions for comparison.

Mass
Students determine how mass is a property of an object that can be measured, and examine how size affects mass. They work with balances and determine what units of measurement are associated with mass. Finally, they determine the...
