Imagine a clock where the big hand advances once a century, and a cuckoo emerges to mark the passage of a millennium! The 10,000 Year Clock is a giant pendulum clock being built inside a mountain in the middle of a desert in Texas. Children explore ideas about how we measure time, and look at how these are used in different types of clock such as hourglasses, sundials, pendulums and water clocks. Children use their ideas to build simple sand or water clocks and try to calibrate their clock to accurately time one minute.
- 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
Children will learn:
- to construct and calibrate a timing device
- to explain how their timer works
- to convert between different units of time
- to compare times of day at different points around the world
