Our world is full of motion and forces. Science of Toys explores the range of forces, such as gravity, friction and contact forces, that affect and change the way things move. Forces are interactions between two objects or materials, and have both size and direction. Unbalanced forces can speed things up or slow them down, make them change direction, or cause them to twist or rotate. Multiple forces can act on an object at the same time to produce an overall effect. This unit covers the Australian Curriculum; Science Understanding description ACSSU1 17.
The Earth, our home in space, is a tiny dot in a very large solar system. Earth and Space explores the resources, including energy resources, we draw from the Earth's crust and the challenges we face in managing the sustainability of these resources. Humans have constantly wondered about the motion of the sun and of the Moon, stars and planets in the night sky. Events such as solar and lunar eclipses were often a source of fear and wonder. This unit investigates our modern understanding of how gravity causes the orbits of the Earth and Moon leading to a range of phenomena such as seasons, the tides, phases of the Moon, and eclipses. This unit covers the Australian Curriculum; Science Understanding descriptions ACSSU115 and ACSSU116.
