In this interactive learning object, students view the ammeter connections for measuring currents in a parallel circuit with three branches on an energy concepts lab board. A brief quiz completes the activity.

Learners examine graphs and read that the heat of fusion is the heat energy absorbed by one mole of solid as it is converted to liquid, while the heat of vaporization is the heat energy absorbed by one mole of liquid as it is converted to gas.

Students use algebra to rearrange formulas and solve for the missing volume, density, or mass quantity.

Learners view movie clips to determine the solubility of two ionic compounds. They also examine a solubility chart and predict the solubility of compounds.

Boyle's Law states that gas volume varies inversely with the pressure at constant temperature and is described by the equation PV = constant. An example of a sample of gas at two conditions of P and V is used to illustrate the law.

In this colorful, interactive object, learners examine how materials on the nanoscale compare with those on the macroscale. The focus is on the difference between macroscale and nanoscale gold in both color and melting point.

In this animated object, learners examine the operation of a zener diode in the forward and reverse bias conditions. A quiz completes the activity.

In this screencast, you'll observe two vehicles moving across the screen at different rates then describe the motion. Additionally, you'll select the corresponding graphs of distance vs. time, velocity vs. time, and acceleration vs. time for each vehicle.

In this screencast, learners examine the lifecycle of fungi including asexual and sexual reproduction. Learners test their knowledge by identifying a diagram. There is a companion crossword puzzle game here: https://www.wisc-online.com/arcade/games/natural-science/science-biology/3016/the-zygomycetes-crossword

In this animated object, learners examine processes that do not use ATP directly including hydrostatic pressure and facilitated diffusion with carrier proteins.

Learners quiz themselves on the conversion factors within and between the metric, apothecary, and household systems.

The purpose of this learning object is to introduce the dental hygienist to the process of documenting a patient's dentition.

In this animated object, learners examine the different phases of a cell's life.

Students solve a molarity problem in a drag and drop exercise.

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

In this animated object, students examine what happens when electrons share molecules.
