Food packaging challenge

Paper bags and bottles seem to be the way to go when it comes to take-out refreshments. But which is the best paper to use? And should stall holders go with glass or plastic for their drinks bottles? It is your job to find the answers.

Science Objectives
i) Give reasons, based on evidence from comparative and fair tests, for the particular uses of everyday materials, including metals, wood and plastic.

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, classification keys, tables, scatter graphs, bar and line graphs.
4. 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.
5. Identify scientific evidence that has been used to support or refute ideas or arguments.

Extended Writing Opportunities
Recount: Write to stall holders and explain your investigation into the insulating properties of a range of materials and make recommendations of materials to store hot drinks and ice cream.
