Read this to the class:
Every morning, Ava walks her dog before school. Her shadow is so long it stretches right across the road, like a giant. When she walks home for lunch, her shadow is small and stubby, right under her feet. "Is my shadow growing and shrinking?" she asks. Your job: watch one shadow all day long and find out why it changes.
Children work in pairs. There are two jobs that swap at each visit: the Tracer draws around the shadow with chalk, and the Measurer cuts a piece of yarn the same length as the shadow.
