Maddie's Do You Know?

Floating and Sand (4x8)

Air date: Apr 29, 2020

Today, Maddie’s at sea! First she visits a boating lake, using her special underwater cameras to find out how the hull of a boat is shaped to help it float on water. She learns how even big heavy things can float because of a force called buoyancy. Next, Maddie heads to a beach to discover how sand is made. She explains how a process called weathering breaks the rocks down to small pieces and how all the tiny grains of rock make sand. She then uses a special microscope camera to see how thousands of bits of different minerals like quartz make up sand.
