Worksheet Overview

Mrs. Bates's science class were working on electric circuits.


First of all, they were investigating how the length of a piece of wire affected different components in a circuit. They started by setting up a simple circuit using a cell and a bulb connected by two clips into which lengths of wire could be inserted to complete the circuit:




Mrs. Bates divided her class into ten groups and gave each group three different lengths of wire for them to test: 10cm, 20cm and 30cm.
