Changes of Materials

Science Year 5 Changing Materials

The Science Museum wants to expand its Science Kitchen education resource to include more exciting materials investigations. You have been selected to devise and write the materials to be included. You will need to carry out a range of investigations into the changes that occur to certain materials when they are heated, cooled and mixed with other materials to ensure your content is accurate and inspiring. Get your lab coats on - it’s going to get messy!

Session 1 Soluble solutions

Objectives

Dissolve into your first Science Museum commission by investigating soluble and non-soluble materials. Develop your initial education pack contributions and link them to an exclusive Pinterest board by creating your own QR code.

Science Objectives
i) Compare and group together everyday materials on the basis of their properties, including their solubility and response to magnets.

ii) Know that some materials will dissolve in liquid to form a solution.

Working Scientifically

  1. Plan different types of scientific enquiries to answer questions, including recognising and controlling variables where necessary.
  2. Record data and results of increasing complexity using scientific diagrams and labels, tables and line graphs.
  3. Use test results to make predictions to set up further comparative and fair tests.
  4. Report and present findings from enquiries, including conclusions, causal relationships and explanations of and degree of trust in results, in written form.
