Understanding How Science Works

Produced by Nelson Thornes, these materials are designed to support AQA GCSE science specifications. However, they can readily be used with other specifications to support students in their understanding of How Science Works.

Topics covered look at:

  • Data analysis and the Big Bang
  • Examining the claims made for a cholesterol-reducing food spread
  • Experimental design and the decomposition of carbonates
  • Testing the effectiveness of disinfectants
  • Investigating the expansion of water on freezing
  • Examining evidence about global warming
  • Looking at data on selection in Peppered moths

Before the Big Bang

Produced by Nelson Thornes, this resource helps students look at aspects of how science works. In this activity students are given some information about the Large Hadron Collider and the Big Bang Theory. They are asked to analyse and interpret the secondary data and differentiate between theory and fact. Students...

Can We Believe the Claims?

Produced by Nelson Thornes, this resource helps students look at aspects of how science works. In particular, students are presented with data from a scientist who is working for a company making a food spread. The company claims that the spread reduces blood cholesterol. Students are asked questions regarding the...

Competing Carbonates

Produced by Nelson Thornes, this resource helps students look at aspects of how science works. This activity challenges students to look critically at a plan to investigate the relative ease with which metal carbonates decompose. The plan involves the decomposition of carbonates to release carbon dioxide and...

Disinfectant Concentration and Effectiveness

Produced by Nelson Thornes, this resource helps students look at aspects of how science works. In this activity students are given the results of an experiment to investigate the effectiveness of different concentrations of disinfectant and their effectiveness at killing bacteria. Students are asked to suggest a...
