w/c 8 th June – Science What’s making it move?
Activity 1 Let’s revise what you learnt last week . Complete printed worksheet – ‘ wc 8 th June Science – Pushing or Pulling Forces’ Can you also add an arrow to each picture to show the direction of the force?
Forces Watch the video: https://www.bbc.co.uk/bitesize/clips/zp4g9j6 There are lots of different forces in action – can you identify where objects are being moved by wind?
Look outside… Look outside, can you see the trees moving? Leaves? Clouds? What’s making them move? Can you see what is making them move?
Your Task Step 1 Make your paper windmill by either: a) Follow these instructions to make a paper windmill (you could bend a paperclip if you do not have a paper fastener) https://www.metoffice.gov.uk/weather/learn-about/met-office-for- schools/other-content/other-resources/experiments/windmill Printed windmill template ‘w/c 8 th June Science paper windmill template’ b) Follow the printed instructions as an alternative method w/c 8 th June Science paper windmill instructions’
Your Task Step 2 If you can, use an outside space to see how well your windmill turns. Try placing your windmill in different places – does this make a difference? Try running with your windmill. Try holding the windmill at different angles as you run to see if this makes a difference. Or you could ask an adult and use a hairdryer or fan inside!
Questions to Consider What is making your windmill turn? What type of force is it? Push or Pull? Why do you think that? Can you see the force? Does this matter?
Extension Do you think you could improve your windmill? Could you make your own design to make it more effective? Could you make different sized windmills to investigate how the size of the blades affects how well the windmill turns?
Moving Air = Wind Wind = Pushing Force The air is providing the force to move the windmill, even though we cannot see it. It is pushing the blades. This is a contact force .
Moving Air = Wind Wind = Pushing Force When we make observations, we must involve all the senses. We cannot see the air making contact with the object but simple activities, such as blowing on our hands, enable us to feel the contact of air and the force that exists.
