Lesson Planning

Teaching

• Design and conduct a fair test to answer a scientific question.
• Record results in tables and graphs.
• Draw conclusions and raise further questions.

Activities

1. Take part in an active quiz game to rehearse and extend learning on sound (Yrs3&4).
2. Consider different animal ears as sound detectors and design a class investigation to compare hearing with bare ears, a cupped hand around your ear or a cardboard animal ear (Yrs3&4).
3. Write notes on the investigation and findings (Yr4) use data to construct a bar graph (Yr3).
4. Discuss findings and draw conclusions (Yrs3&4).

Investigation - exploring, analysing secondary sources
The band now needs you to find out how the audience will hear the sound when the vibrations reach their ears. Why are ears that shape? Do big ears hear better than small ears? Why do you have 2 ears? What happens to vibrations when they reach your ears? Try a carousel of activities.
Year 3 - Record results using annotated drawings on a scaffolded results sheet.
Year 4 - Find own ways to record results and try to explain findings in terms of scientific understanding.
