This editable differentiated lesson pack focuses on comparing materials to find out which one keeps a hot drink warm for the longest. Children learn how thermal conductors and insulators behave and use a comparative test to investigate how well different materials slow heat loss. In the main activity, pupils set up a fair test by changing only the material wrapped around each cup, measuring temperature at timed intervals, and recording results in a table. The lesson strengthens understanding of variables, builds confidence in taking accurate measurements, and helps children draw conclusions based on clear evidence. The file includes the following resources:- editable teaching presentation - editable investigation worksheets - editable additional activity ideas - editable lesson plan - editable focus assessment worksheet National Curriculum objectivesScience: Year 5Pupils should be taught to:

 give reasons, based on evidence from comparative and fair tests, for the particular uses of everyday materials, including metals, wood and plastic  compare and group together everyday materials on the basis of their properties, including… thermal conductivity

Working scientifically:

 Planning different types of scientific enquiries to answer questions, including recognising and controlling variables where necessary Taking measurements, using a range of scientific equipment, with increasing accuracy and precision, taking repeat readings when appropriate
