Learners calculate gas density from the standard molar volume and observe how the density increases with the increasing molecular weight of the gas.

In this animated object, learners view hydrogen and hydroxide ions in a solution. A brief quiz on the basic principles of the term pH completes the activity.

Learners examine how chemists use moles to "count" atoms by weight. Examples are given.

In this well-illustrated object, learners examine the structures and properties of the four types of solids: molecular, metallic, ionic, and covalent network. Five interactive questions are provided.

In this animated and interactive object, learners examine how a variable voltage is obtained from a variable resistor that is wired as a potentiometer across a fixed DC power supply.

Learners identify combination, decomposition, displacement, and combustion types of redox reactions. They also watch a video clip that demonstrates the reaction of sodium and water.

Learners view colorful animations showing the operation of a VR stepper motor.

The learner reads an explanation of all of the elements that comprise a future-state map. A map is shown.

In this learning activity you'll review independent and dependent variables and view a demonstration of the positive and negative correlation.

You will play against your classmate. One of you should share your screen.
