Heavy and Heavier

Lab Summary

Use a force sensor to learn about the property called weight that can be measured, and to recognize that an object's weight is not necessarily related to its size.


To understand this content, students:

  • Observe properties of matter such as size, weight, and shape
  • Classify objects as heavy and heavier

Sensors / Equipment Used:

PASPORT Force Sensor


Designed to measure both pulling and pushing forces. Uses range from collisions to tug-of-war.

Materials Used:

Container (bucket or basket) to attach to the force sensor hook
Toy car, truck, or other vehicle 
Balloon, inflated and tied 
Apple, potato, or other small fruit or vegetable
Melon, eggplant, or other large fruit or vegetable
Polystyrene (foam) packing material, picnic cooler, or purchased polystyrene craft material, as large as possible
String, to hang the container on the force sensor hook - Several pieces

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.
