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.

Graphing Lines

Graphing Lines gives the opportunity for students to explore the parameters of a linear equation; how modifying the graph affects the equation and how modifying the equation affects the graph. Students can draw reference lines y=x and y=-x to help with their deliberations. Students may change the point of...

Gravity Force Lab

This simulation allows students to visualise the gravitational force that two objects exert on each other. It is possible to change properties of the objects in order to see how that changes the gravitational force between them.

The simulation can be used to:

*Relate gravitational force to the masses...

Least Squares Regression

This interactive simulation gives the opportunity for students to explore Least-Squares Regression. There are a number of different options available from the drop-down menu or students can plot their own points. Students then use the sliders to add their own line of best fit, residual lines and squared residuals...

Molarity

This simulation explores the factors which determine the concentration of a solution. It illustrates the relationships between moles, litres and molarity by adjusting the amount of solute and solution volume.

The moles of solute and the volume of solution (water) can be changed using sliders to make...
