Objectives

Working with play figures frozen in ice, devise an investigation to release them. How can you melt the ice quickly to free the figure? Can you do it slowly so it takes a lot longer?

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

  • Ice Rescue! resource

Additional Resources

  • Large blocks of ice with play figures trapped (water frozen in bowls
  • Trays
  • Clipboards
  • Paper
  • Pencils
  • Cameras/recording devices

Lesson Planning

Teaching

  • Understand that water is a material and ice is water in a different state.
  • Observe a block of ice and consider how to change its state.
  • Devise an investigation to melt the ice quickly or slowly.
  • Make predictions about the outcome and test those predictions in the classroom.
  • Generate questions about ice and water and consider why it is useful for people to know how to regulate the melting of ice.

Activities

  1. Understand that water is a material and ice is water in a different state.
  2. Consider, predict and then explore ways of speeding up or slowing down the melting of ice.
