The boat challenge

Science Objectives
i) Explain that unsupported objects fall towards the Earth because of the force of gravity acting between the Earth and the falling object.

ii) Identify the effects of water resistance, that acts between moving surfaces.

Working Scientifically

1. Plan different types of scientific enquiries to answer questions, including recognising and controlling variables where necessary.
2. Take measurements, using a range of scientific equipment, with increasing accuracy and precision, taking repeat readings when appropriate.
3. Record data and results of increasing complexity using scientific diagrams and labels, tables, scatter graphs, bar and line graphs.
4. Use test results to make predictions to set up further comparative and fair tests.
5. Report and present findings from enquiries, including conclusions, causal relationships and explanations of and degree of trust in results, in oral and written forms such as displays and other presentations.

Extended Writing Opportunities
Explanation: Based on your scientific investigation, explain clearly to the recovery team leader which shape of boat is best for crossing safely across a water way and why, giving scientific reasons.
