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.
