On The Move

(KO, KW, K/1HD)

Why do things move? The universe and everything in it, is continuously moving and changing.

Movement and change are concepts that we need to understand and make sense of the world around us. They are linked to concepts of energy and force. Scientists and engineers apply these concepts to study the performance of athletes and in the design of toys, cars and spacecraft.

Students develop an understanding of how things move. They explore the push and pull forces they can use to move objects in ways such as sliding, bouncing and spinning. Through investigations, students observe and gather evidence about rolling objects and explore the idea of fair testing.

 

Spot The Difference

(1J, 1P, 1NC, 2D, 2H)

Changes are happening all around us. Chocolate melts in the sun, water evaporates from puddles and cement hardens in the open air. Predicting the change that can happen to everyday materials is important in understanding the best way to manage things such as, food handling and cooking, construction and packaging.

Students explore change through the context of food including spaghetti, chocolate and popcorn. Students learn about how heating or cooling a food can change its properties and whether that change can be reversed or not.

 

Smooth Moves

(2/3MW, 3P, 3S, 4B, 4C, 4/5M)

Why do balls roll?  Why do apples fall from trees? Why do some things slide across ice but not on carpet? What makes our bikes stop when we brake?

We use all types of forces including friction, gravity and pushes and pulls when we exercise, ride bikes and drive cars. Engineers and scientists use their knowledge of forces and motion to design things for our homes, work and school.

Through hands-on activities students identify forces that act at a distance and those that act in direct contact and investigate how different-sized forces affect the movement of objects.
