Lesson Planning

Teaching

• Be challenged to find the strongest paper to wrap a present.
• Understand that paper varies in strength and think of a way to test the strength of different papers.
• Plan, make predictions, and carry out an investigation.

Activities

1. Investigate paper strength, working in groups and recording their findings.
2. Predict the outcome of the investigation and produce a simple bar chart or annotated drawings of the results.

Investigation - fair testing, problem solving
Be challenged to find the strongest paper to wrap a present. Collect sheets of different types of paper and make them the same size. Make a hole in each sheet and hang a weight from it, adding weights until the paper tears. Record the results.
