Beer's Law Lab
Conditions of Use:
No Strings Attached
Rating

The PhET project at the University of Colorado creates "fun, interactive, research-based simulations of physical phenomena." This particular one deals with Beer's Law. "The thicker the glass, the darker the brew, the less the light that passes through." Make colorful concentrated and dilute solutions and explore how much light they absorb and transmit using a virtual spectrophotometer! The simulation is also paired with a teachers' guide and related resources from PhET. The simulation is also available in multiple languages.

Energy Forms and Changes
Conditions of Use:
No Strings Attached
Rating

This simulation lets learners explore how heating and cooling adds or removes energy. Use a slider to heat blocks of iron or brick to see the energy flow. Next, build your own system to convert mechanical, light, or chemical energy into electrical or thermal energy. (Learners can choose sunlight, steam, flowing water, or mechanical energy to power their systems.) The simulation allows students to visualize energy transformation and describe how energy flows in various systems. Through examples from everyday life, it also bolsters understanding of conservation of energy. This item is part of a larger collection of simulations developed by the Physics Education Technology project (PhET).

Gravity and Orbits Phet Simulation and Lab
Conditions of Use:
No Strings Attached
Rating

This activity was developed for6th grade classrooms studying the Solar System, though can probably be used in a variety of settings. Students will be able to: • Draw motion of planets, Moons and satellites. • Draw diagrams to show how gravity is the force that controls the motion of our solar system. • Identify the variables that affect the strength of the gravity. • Predict how motion would change if gravity was stronger or weaker. The Student Activity includes pre- and post-labs, but these can be excluded.

Standard 6.1.2 Develop and use a model to describe the role of gravity and inertia in orbital motions of objects in our solar system.
