Year 2 Lesson 7

This 90-minute lesson helps teachers guide learners through the differences between apparent solar time, mean solar time and sidereal time. Using practical demonstrations, worked calculations and observation-planning examples, learners explore why stars rise approximately four minutes earlier each day, why true solar noon does not always occur at 12:00, and how sidereal time can identify when an astronomical target is highest in the sky. The lesson emphasises clear visual explanations, calculator-supported practice, links to learners’ observation logs and differentiated questions for a range of abilities.
