Up periscope

We know that the thief could see round corners, and likely used a periscope. All suspects have one, but are they using materials that reflect well enough to see? Can you investigate and eliminate another suspect?

Science Objectives
i) Recognise that light appears to travel in straight lines.

ii) Use the idea that light travels in straight lines to explain that objects are seen because they give out or reflect light into the eye.

iii) Explain that we see things because light travels from light sources to our eyes or from light sources to objects and then to our eyes.

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. 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.
