Does matter really matter? Properties of matter are discussed by Sam and RJ: mass, volume, and density. They differentiate between mass and weight. They explain how to measure these properties. Make sure to teach your class about other...

In this density laboratory worksheet, students complete 2 prior knowledge questions, then use the "Density Laboratory Gizmo" to complete several activities, answering short answer questions when finished.

Why do some things float and others sink? A creative simulation allows learners to adjust mass and volume of an object to affect its buoyancy in water. A graph records the effect of each manipulation.

Use water displacement and a mass balance to determine the density of various objects in this interactive simulation.

[Free Registration/Login Required] Find out what mathematical function should be performed in order to move from mass to moles and back again. After the activity, answer one multiple choice, challenge question about the topic.

[Free Registration/Login Required] Find out what mathematical function to perform when converting between particles and moles. Then answer one challenge question about the topic.

Choose a calculation for density p, mass m or Volume V. Enter the other two values and the calculator will solve for the third in the selected units.

Practice your density, mass, and volume calculations with these interactive review problems.

Use these word problems as a review in the areas of mass, density, and volume.

Why do hot air balloons float? This resource from the NOVA Web site offers a series of interactive activities that illustrates the physics of hot air balloons.

[Free Registration/Login Required] Students will be able to change the mass and volume of an item and observe if it floats, sinks, or remains at a certain depth in the water. Students will also be able to change the liquid in level 2.

This lab was designed to allow students to collect data for the Force Gravity vs. Volume lab for materials and locations that we cannot do in the classroom. Students will fill the bucket to different levels and record the force on the...

In this interactive lesson, learn what the "physical properties" of matter are and how can they be measured and observed.

What kind of unit conversion would you like to do? This site will allow you to do a multitude of conversions. Just click on the specific measurement you are needing to convert. It also provides a history of measurements and a chart of...
