Lesson Planning

Teaching

• Investigate materials for their useful properties, considering questions such as: how can we know that this material will not let the rain through? How can we test it? (Yr2)
• Use pipettes to simulate raindrops and experiment with the different materials (Yr1).
• Observe and record the results (Yr1).
• Make hypotheses about why certain materials do not let water through (Yr2).

Activities

1. Understand, through exploration and investigation, that some materials are more suitable than others for mending an umbrella because of their physical properties.
2. Understand and articulate their scientific reasoning for selecting and investigating certain materials.

Investigation - observing over time, problem solving
Investigate materials for their useful properties, considering questions e.g. how can we know that this material will not let the rain through? How can we test it? Use pipettes to simulate raindrops and test different materials.
Year 1 - Observe and record the results.
Year 2 - Make hypotheses about why certain materials do not let water through.
