New Molecule Polarity Sim

Molecule Polarity

Try our new Molecule Polarity sim. When is a molecule polar? Change the electronegativity of atoms in a molecule to see how it affects polarity. See how the molecule behaves in an electric field. Change the bond angle to see how shape affects polarity. See how it works for real molecules in 3D.

Register for iNACOL Webinar with PhET Director, Kathy Perkins, and K12 Specialist, Trish Loeblein

Register now for a an iNACOL Teacher Talk webinar on September 15 at 6 PM ET. Here’s some information on what we’re going to cover:

Using PhET Simulations for Science Inquiry: Free, researched, web-based resources
Trish Loeblein, PhET K12 Specialist and Evergreen HS Teacher
Kathy Perkins, Director, PhET Interactive Simulations, University of Colorado

Engage your students in STEM learning with free simulations. The 102 sims are animated, interactive, game-like environments which engage students in active thinking, encourage experimentation, and help develop visual and conceptual models of physical phenomena. This session will introduce the sims and the research that informs their design and use. Session participants will exchange ideas for using PhET sims with their online learning environment.

Moving Man for Algebra-Based Physics

Moving Man

Wendy Adams, a professor at UNC, recently used the Moving Man Lab in her algebra-based physics course alongside a physical lab with motion detectors. Here’s what she said:

“It was amazing to see the difference. When they used Moving Man there was a lot of very productive physics talk. When using the motion detectors, there was some good talk but it came with long breaks of trying to make sure they accomplished the given movement, printed and labeled their graphs, etc… I was amazed at how effective and efficiently the activity worked with Moving Man. So were the other faculty.”
