                        Featured Sims:
                        Explore Snell's Law and More with Bending Light

                                        Investigate the bending of light (refraction) between two mediums with different refractive indices with the new Bending Light sim. See how changing from air to water to glass changes the bending angle.
                                        Play with prisms of different shapes and make rainbows. Use more tools to measure light intensity and probe E-field versus time. Students can learn what
                                        determines the angle of refraction, how to apply Snell's law, how the speed and wavelength of light changes in different materials, and how wavelength effects
                                        the angle of refraction. In the end, students will be able to explain how a prism creates a rainbow.

                                     Make learning how to balance a chemical equation more fun with the new Balancing Chemical Equations sim. What can you change to balance an equation?

                                        - Balance a chemical equation.
 
                                        - Explain that the number of atoms of each element is conserved in a chemical reaction.
 
                                        - Describe the difference between coefficients and subscripts in a chemical equation.
 
                                        - Translate from symbolic to molecular representations of matter.

                                    What got you involved in PhET? 
                                    I had some teaching experience, but I was eager to learn more about
                                    how students learn chemistry. PhET gave me an opportunity to grow as
                                    an educator. What I did not expect was how much chemistry I would
                                    learn in the process!

                                    What do you do for PhET? 
                                    I work with the team to design and develop new chemistry sims, and I
                                    help run workshops for teachers. I also study the effect of PhET on
                                    student learning in interview and classroom settings, and present the
                                    research at conferences and in papers.

                            How do you see PhET helping teachers? 
                            I like how the open-source nature of PhET gives science teachers who
                            have little access to lab equipment -- or even the internet -- a way to
                            use inquiry in their classrooms. I am excited to use the sims in my
                            own teaching!
                         
                        
                            How do you see PhET helping kids? 
                            I am continually amazed at how much students learn from using the
                            sims, and how PhET engages students in learning science. PhET gets
                            students to ask their own questions, which is what science is all
                            about!
                         
                        
                            Where do you see PhET going? 
                            I think PhET will grow in two areas: the earth and life sciences, and
                            the middle school level. Our new sim-sharing project will give
                            teachers more ways to use PhET in their classrooms. And of course,
                            stay tuned for more chemistry sims!
