PhET Interactive Simulations

To help students engage in science and mathematics through inquiry, PhET simulations were developed to allow students to investigate cause-and-effect relationships and answer scientific questions through exploration of the simulation.

Several tools in the simulations provide an interactive experience:

*Click and drag to interact with simulation features

*Use sliders to increase and decrease parameters

*Choose between options with radio buttons

*Make measurements in your experiments with various instruments – rulers, stop-watches, voltmeters, and thermometers.

Beer's Law Lab

This simulation explores the Beer's Lambert Law. It allows you to make colourful concentrated and dilute solutions and explore how much light they absorb and transmit using a virtual spectrophotometer.

Curriculum links include:

• Beer's law
• Solutions
• Concentration
• Molarity...

Build an atom

This simulation allows you to build an atom out of protons, neutrons, and electrons, and see how the element, charge, and mass change. Students can then play a game to test their ideas.

Curriculum links include:

  • Atoms
  • Atomic Structure
  • Isotope Symbols
  • Atomic Nuclei...

Color Vision

In this simulation, students create a rainbow by mixing red, green, and blue light. They change the wavelength of a monochromatic beam or filter white light and can view the light as a solid beam, or see the individual photons.

Learning objectives could include:

*Determine what colour the person sees...

Concentration

With this simulation, students build an understanding of solution concentration by varying amounts of solute, solvent, and solution. Experimenting with several different chemicals in solid and concentrated solution form, students can develop qualitative and quantitative relationships.
