Features 29 inquiry based labs designed for elementary students and coordinated with the standards for life, earth and physical sciences.

Electric Circuits

Lab Summary

Use a voltage sensor to test the conductivity of different materials.


To understand this content, students:

  • Build simple series and parallel circuits using AA-cell batteries and light bulbs.
  • Compare the brightness of two bulbs in a simple series circuit to the brightness of two bulbs in a simple parallel circuit.
  • Measure the voltage being applied to the light bulbs in each circuit.
  • Relate the brightness of the light in their circuits to the voltage and the type of circuit.

Sensors / Equipment Used:

PASPORT Voltage-Current Sensor


Allows students to safely measure voltage and current simultaneously without overloading the sensor. For use with PASPORT Interfaces.

Materials Used:

AA-cell battery - 2
Miniature holiday light bulbs with stripped wire ends - 2
Masking tape, ~30 cm
Wide rubber band 
Alligator clip or other pieces of wire with stripped ends - 2

The Associated Bundle:

Elementary School Science Standard Sensor Bundle


This bundle contains the probeware needed to perform all 25 lab activities in the Elementary School Introductory Science Experiments.

Interface Required

This experiment may require software and an interface for data collection.
