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.


Acid Based Solutions

This simulation allows students to:

*Demonstrate an understanding of acid and base strength, given acids or bases at the same concentration, by:

1. Relating the strength of an acid or base to the extent to which it dissociates in water
2. Identifying all of the molecules and ions that are...

Area Builder

Area Builder gives students the opportunity to build any shape and explore the relationship between the area of a shape and the length of its perimeter. The “Game Screen” contains two kinds of challenges: Build a shape and Find the area. There are different levels of increasing difficulty. The teacher notes give...

Balancing Act

With this simulation students can move objects on a seesaw to learn about balance and test what they have learned by trying the Balance Challenge game.

Sample learning objectives include:

*Predict how objects of various masses can be used to make a plank balance.

*Predict how changing the...

Balancing Chemical Equations

With this simulation students can explore the conservation of mass and balance chemical equations. Sample learning objectives include: *Balance a chemical equation. *Recognize that the number of atoms of each element is conserved in a chemical reaction. Describe the difference between coefficients and subscripts in...
