Free Science Demonstrations

PhET provides free interactive simulations of different physics, chemistry and biological phenomena.  PhET enables students to make connections between real-life phenomena and the underlying science, deepening their understanding and appreciation of the world around them.
To help students visually comprehend concepts, PhET simulations animate what is invisible to the eye through the use of graphics and intuitive controls, such as click-and-drag manipulation, sliders, and radio buttons. The simulations offer measurement instruments including rulers, stop-watches, voltmeters, and thermometers. This is fully interactive at every point, and, as the user manipulates these tools, responses are immediately animated, illustrating cause-and-effect relationships.

All grade levels can use these animations and online activities/simulations. 

Here are some examples from the Sask. Curricula that could access these simulations.

Grade 4 Physical Science:  Light and Sound units
