Things are building up on week two of Girlstart’s After School programs. After a mini lesson on density and buoyancy, the girls predicted which types of foil objects would float and sink.
Girls then worked in teams to design various shapes that would float or sink. After formulating their hypothesis, they tested their designs in water and evaluated their results. Throughout the process, they applied their knowledge of the scientific method as they learned how to plan, design, develop, and improve their foil shapes according to density and mass.
