Have You Seen the Newly Redesigned “For Teachers” Page?

For Teachers

We’ve made it easier to learn about how best to use PhET simulations in your instruction. All centrally located now on the “For Teachers” page, you will find a variety of useful information along with a new video: Teachers and Students Speak: An in-depth look at the PhET simulations and their uses in college and K12.

Use the “Tips” button to find videos and written resources on integrating PhET sims. Easily search for teacher-submitted activities including labs, homework assignments, lectures, activities, and concept questions with the “Browse” button. Or, if you’d like to “Share” your activities with the PhET community, learn how to contribute your own materials to our growing database.

Thanks for supporting the PhET Teacher Community.

Studying Forces in Physics?


Try the  HTML5 Forces and Motion: Basics simulation. Explore the forces at work in a tug of war or pushing a refrigerator, crate, or person. Choose between the Tug of War, Motion, Friction, and Acceleration tabs. Ideal for elementary, middle and high school, students will learn how forces affect the motion of an object.

New Three-Day Activity for Graphing Lines


Try the latest teaching guides from PhET’s Amanda McGarry for #HTML5 Graphing Lines. These activities can be used as part of a three-day sequence or individually. The lessons are aligned with the CCSS in Mathematics and the Standards of Mathematical Practice and include complete outlines as well as annotated activity sheets.

  • Day 1: Slope allows students to make connections between the slope formula and a graphed line, and to discover how the slope formula works.
  • Day 2: Slope-Intercept has students exploring slope-intercept form of a line as they manipulate either equation or graph.
  • Day 3: Point-Slope has students exploring point-slope form of a line and testing their knowledge of graphing lines with the built-in game.

New #HTML5 Area Builder Simulation


In the new #HTML5 Area Builder simulation, students can flexibly explore ideas related to area and perimeter. They can find the area of rectangular and irregular shapes, discover the relationship between area and perimeter, and apply fractional knowledge as they build shapes with a given area and perimeter.

Area Builder is appropriate for any grade level that is studying area and perimeter and is specifically aligned with Common Core State Standards in elementary and middle school mathematics. For some teacher tips written by PhET’s Amanda McGarry, see

New Three-Day Activity for Learning Fractions

Fractions Intro

Try the latest teaching guide for Fractions Intro. Just like the three-day lab for Circuit Construction Kit (DC Only) featured in our blog last week, this three-day activity was also developed between Meaghan Hixson and our PhET Team.

  • Day 1: What is a Fraction?: students explore what makes a fraction by manipulating numerators and denominators. Through discussion and various fraction representations, students learn that numerators are the number of pieces being considered and the denominators are the number of equal pieces in a whole.
  • Day 2: Comparing and Ordering Fractions: students use their knowledge of numerators/denominators from Day 1 to compare and order fractions and come up with rules for discussing the size of fractions.
  • Day 3: Equivalent Fractions: students explore fraction equivalence using the Build a Fraction sim. By using the sim to create various representations of  the same amount, students explore and discuss rules for finding equivalent fractions.

New #HTML5 Wave on a String Now Online!


Try the newly published #HTML5 Wave on a String simulation. Watch a string vibrate in slow motion. Wiggle the end of the string and make waves, or adjust the frequency and amplitude of an oscillator. Adjust the damping and tension. The end can be fixed, loose, or open. With Wave on a String, students will learn about wave properties and be able to predict behavior of waves through varying media and different endpoints.

Did You Miss Trish Loeblein’s Webinar: Personal Experiences on Using PhET?

Did you miss Conifer Chemistry Teacher and PhET K12 Specialist Trish Loeblein discuss her personal experiences on how and why she uses PhET in her chemistry classroom? Over 190 listened to and chatted with Trish as she shared her strategies, course planning documents, lessons, and student handouts for regular and advanced chemistry.

See the archived version at:

 Thanks AACT and all those that attended.

New #HTML5 Color Vision Simulation

Color Vision Sim

Try the new #HTML5 Color Vision simulation. Make a whole rainbow by mixing red, green, and blue light. Change the wavelength of a monochromatic beam or filter white light. View the light as a solid beam, or see the individual photons.

Students will learn to:

  • Determine what color the person sees for various combinations of red, green, and blue light.
  • Describe the color of light that is able to pass through different colored filters.
