Lesson Planning

Teaching

• Investigate the 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?
• Use pipettes to simulate raindrops and experiment with the different materials.
• Observe and record the results.
• Make hypotheses about why certain materials do not let water through.
• Consider the question: if you did not have an umbrella, and it was raining hard, what other everyday objects could you use to keep the rain off your head? Why would they work?

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. Be able to articulate their scientific reasoning for selecting and investigating certain materials.
