This PhET Interactive simulation allows students to investigate the index of reflection and refraction of light. This concept it difficult to illustrate due to the immense speed of light and this simulation slows it down nicely. Furthermore, this simulation gives students the ability to measure the light intensity, angle of reflection and refraction and analyze how light waves bend through lenses- all things that are both costly and difficult to measure in a lab setting.

An alphabetical listing of the the PhET project sponsored by The University of Colorado. This contains numerous fun, research-based, interactive website simulations for many common topics in science and mathematics,

This simulation not only illustrates how a lab technician extracts DNA from a sample but it also shows a few different tissue samples that a technician can extract DNA from and walks the students through a click and move simulation. I like how it walks students through the steps of extracting DNA and discusses why the technician does the steps they do.

This PhET Interactive simulations creates a fun game out of electric fields. The objective is to get the positive particle to go into a goal using only charged particles. Each particle either attracts or repels the objective particle and every particle modifies the existing field. This is a great trial and error method to introduce how field forces affect the area around them.

This is a fun mix of treasure hunting and forensics. In this simulation you are trying to track down potentially stolen gold. To solve the mystery students need intuition, logic through forensic science and the internet.

Projectile motion is a standard that all physics classrooms work on and many students struggle with. This simulation is actually a two-for-one. The first set allows students to manipulate some basic variables that affect the range of a motorcyclist based on his velocity and angle of ramp. The second allows students to manipulate a few variables in the hopes of getting an archer to shoot a falling coconut. It is a great illustration on how all objects, no matter their horizontal velocity, will fall at the same rate. Once the students finish shooting the monkey who drops the coconut, they can investigate the relationship and draw some impressive conclusions.

Quality hub containing several java script physics simulations.

This web site gives students a chance to be a detective. Students are often excited by all of the forensic science programs that are on the television. This gives them an opportunity to solve a theft by reading through witness interviews and examining a crime scene through point and click interaction.
