Cassie's Harbour Quest: A Buoyancy and Marine Science Adventure

By Suneeta Mall

Cassie is a curious six-year-old who loves asking questions and doing experiments. When her family heads to Sydney Harbour for a surprise fishing trip, she discovers that science is everywhere-from the chocolate cake in her kitchen to the mysterious creatures hiding in rock pools

Join Cassie and her little brother Caleb on an adventure of discovery as they uncover:

Why mud cake is denser than sponge cakeHow fish breathe underwater using special gillsWhat makes enormous ships float while anchors sinkWhy some animals are masters of disguise

Along the way, they meet sideways-walking crabs, water-powered sea stars, and fish with tiny balloons inside their bellies

Packed with hands-on experiments, catchy songs, and real science inspired by renowned Australian marine biologist Professor Emma Johnston, this adventure will spark curiosity in young readers and prove that the best discoveries begin with one simple question:

"But why?"

Perfect for curious minds ages 5-10
Includes take-home experiments to try at home
