Adaptive teaching
Pupils needing extra support
Could use the Resource: Designing and making a sundial (support) to stick onto a paper plate to make their sundial (some of the times are already marked on to help them with the task of calibrating); could wait for a sunny day to calibrate their sundial with just one time of day.
Pupils working at greater depth
Should compare a wristwatch to a sundial and compose a list of the advantages and disadvantages of each (for example, their sundial does not work when it is cloudy or at night, it cannot be worn and it does not show minutes while a wristwatch usually requires a battery and can only really be used by one person); could choose an extension activity relating to the sundials, day and night or the seasons from the Resource: Stretch and challenge: Earth and space.
