PhET Lab Extensions

Summary

This resource collection extends existing Switch Classroom investigations into free PhET interactive simulations, giving students a guided, screen-based way to explore circuits and electromagnetism. Through step-by-step simulation guides, data collection, and short-answer questions, students test variables, take measurements, and draw conclusions the same way they would with hands-on materials.

Included Activities

1. Circuit Construction Kit: DC

This activity walks students through the PhET Circuit Construction Kit simulation, from building a basic series circuit through parallel circuits, conductors and insulators, and Ohm’s Law.

Activity Features:

    • Student Guide: A four-part, step-by-step walkthrough with data tables for current, resistance, and voltage readings
    • Includes learning targets, a full answer key, and a pacing estimate for each part (available in the lesson’s teacher guide)

Students move from simple circuit-building to using an ammeter to collect their own data and derive the relationship between voltage, current, and resistance.

2. Faraday’s Electromagnetic Lab

This activity walks students through the PhET Faraday’s Electromagnetic Lab simulation, from a stationary pickup coil through a working generator.

Activity Features:

    • Student Guide: A two-part walkthrough covering induction voltage variables and generator design
    • Includes learning objectives, a full answer key, and a pacing estimate for each part (available in the lesson’s teacher guide)

Students trace the energy transformations in a working generator and connect their observations to how hydroelectric power plants meet changes in electricity demand.

Instructional Value

Together, these resources help students:

    • Collect and interpret quantitative data from a controlled simulation
    • Understand core electricity concepts: current, voltage, resistance, and Ohm’s Law
    • Investigate electromagnetic induction and how generators convert motion into electricity
    • Practice making and testing predictions with real evidence
    • Connect simulation results to real-world power generation and engineering decisions

Best Fit For

    • Middle and high school physical science, physics, or earth and environmental science courses
    • Introduction to Electricity and Science of Electricity units
    • Virtual learning days or substitute lesson plans
    • Reinforcement after a hands-on circuits or electromagnetism lab
    • Make-up work for a student who missed a lab day
