Activity #6 'Nothing' Matters: A Demonstration
Students observe the 'pouring' of a gas. They compare the masses (weights) and densities of two gases. Pupils define the following terms: matter, mass, and density. Students answer questions after watching the demonstration.
Curated OER
Determining Liquid Densities
Students practice determining liquid densities in a short, hands-on lab activity. Students use a graduated cylinder to measure out 100 milliliters of a liquid, find its mass using a balance, and record measurements in a data table....

Graphical Determination of Density
Students determine the density of metal shot by a graphical method using significant digits in making measurements and calculations. Students graph a seris of laboratory measurements and determine density from a mass verses volume graph.
Curated OER
In-Line Inertia
Students practice calculating the moment of inertia when discussing a skater and the position in which it is best to spin. After class discussion, students practice calculating inertia on their own.

Students determine if carbon dioxide has mass. In groups, they use a standard set of materials to test the carbon dioxide. They answer questions on their lab sheet and discuss them as a class.
Curated OER
Rocks, Their Mass and Volume
Learners measure volume using water displacement and mass using a balance. Once they have calculated these two values they will then calculate density while at the same time working on long division. After the activity and explanation of...
Curated OER
What Goes Up Must Come Down!
Learners hypothesize about the nature of falling objects, design an experimental test to answer the question using everyday objects, analyze data to form conclusions, and infer that mass does not affect the speed of falling objects. This...
