Unit 7F: Simple chemical reactions

QCA
About this unit

In this unit pupils:

  • are introduced to the idea that chemical change results in new substances that are different from the ones from which they were made
  • explore some simple chemical reactions of acids in which a gas is made
  • explore burning as a chemical reaction involving a gas, air or oxygen
  • identify hydrogen and carbon dioxide as substances made during some of these reactions
  • work with gases to understand that gases are real materials
  • begin to use word equations as shorthand descriptions of reactions

In scientific enquiry pupils:

  • learn techniques for testing for gases, using laboratory equipment effectively and taking action to control risks
  • present observations in ways which enable patterns to be seen
  • make generalisations from observations
  • suggest and evaluate explanations of observations
  • investigate the role of air in the burning of a candle

This unit is expected to take approximately 7 hours.
