Investigation Hypothesis and Variables

Students are required to make hypotheses and draw graphs for continuous and categoric data as part of their Individual Skills Assessment (ISA) for GCSE. This resource presents a hypothesis as a 'best guess' or proposal, intended to explain facts or observations available, prior to doing an investigation. Students work collaboratively to plan the following investigations, coming up with hypotheses and considering the variables:
  • size of chickens and the eggs they lay
  • 100 meter running time and age of athlete
  • number of butterflies and car pollution
  • car manufacturer and car pollution
  • contraceptive pill efficiently

They then plot graphs of data from similar contexts to their planned investigations deciding if the graphs should be bar charts or scatter plots/line graphs depending on whether or not the variables are continuous or categoric.

Investigation Consecutive Sums

Can all numbers be made in this way? For example 9=2+3+4, 11=5+6, 12=3+4+5, 20=2+3+4+5+6
By definition, a problem is something that you do not immediately know how to solve, so learning how to solve something unfamiliar is not straightforward. Tackling an extended problem is difficult.

This lesson gives pupils an opportunity to engage in mathematical thinking(ta) and develop their higher order(ta) thinking skills on a problem that is accessible but which has interest. For example, the problem is presented in diagrammatic and numerical ways.

The plan suggests several visualisation(ta) methods to present the same underlying task. It should be useful for teachers to compare these different presentations and either to select the one that they feel will be most useful for their pupils or explore ways for the pupils to see the links between the different methods. The assessment(ta) ideas, using other pupils' solutions from the NRICH website are widely applicable to other problems too.

Investigation Scientific Definitions

Students are required to make use of a number scientific definitions as part of their Individual Skills Assessment (ISA) for GCSE. This resource uses the following activities in an attempt to liven up the teaching of these words:
  • anagram activity
  • card match activity
  • Taboo game
  • crossword
Investigation Persuasive argument and evidence-based conclusions about the best car

Got a new motor? Talk about your investigation like a scientist
This activity involving inquiry(ta)aims to develop children’s ability to support their conclusions with evidence. The teacher will model(ta) and encourage the use of the language(ta) that children require to discuss or present their data. The teacher can explain their rationale using the lesson below.
