Mending a torn umbrella: Part 1

Science Year 1
This unit is part of Year 1 Science Marvellous Materials

Objectives

Look at a selection of materials and consider which one is best for fixing a torn umbrella. Explain your selection and predict the outcome.

Science Objectives
i) Distinguish between an object and the material from which it is made.
ii) Identify and name a variety of everyday materials, including wood, plastic, glass and metal.
iii) Describe the simple physical properties of a variety of everyday materials.
iv) Compare and group together a variety of everyday materials on the basis of their simple physical properties.

Working Scientifically

  1. Ask simple questions and recognise that they can be answered in different ways.
  2. Observe closely, using simple equipment.
  3. Perform simple tests.
  4. Identify and classify.
  5. Use their observations and ideas to suggest answers to questions.
  6. Gather and record data to help answer questions.

You Will Need

Provided Resources

  • Different umbrellas and resource presentation

Additional Resources

  • A torn umbrella
  • Samples of materials including a selection of suitable fabrics (hessian, felt, paper, cotton, plastic, oil skin, carpet, etc.) and also unsuitable materials such as metal and wood
  • Cameras or recording devices

Lesson Planning

Teaching

  • Recap on how different objects are made from different materials.
  • Fix a torn umbrella, using materials they select for their useful properties.
  • Discuss their selection of materials for fixing the umbrella: what properties does this material have that makes it a good choice?
  • Discuss their designs and make predictions.

Activities

  1. Explore a range of materials with a view to fixing a torn umbrella.
  2. Understand some materials may be suitable whilst others are not, using the language of useful properties.
  3. Discuss and explore how to test the materials in an investigation and make simple notes about those thoughts.
