Where do you think the different types of plastic come from? Visit www.shift.how for ideas on how to reduce plastic consumption.

Have you noticed how water in a pool is colder down the bottom? Isla does a cool experiment to show how water at different temperatures has different density levels. What is another reason for water having different densities? How does different water density affect the movement of the ocean currents?
