Vroom! Vroom! Vroom... into the world of transportations! Children are always excited and amazed looking at the different types of transportations move in the world. They did different experiments to learn and understand how these amazing transportations move.
Land Transportation
Zi Yang took two cars, predicted and experimented on the speed and length of the two cars when they travelled down 2 different height of ramps. He also learnt that the cars used kinetic energy when they moved down the ramps. Look at how far the orange and white cars moved! He used golden bead as a counting unit to measure which car has moved further.
Water Transportation
How does a ship floats?
Children leant that gravity force will pull the weight of an object into the water while buoyancy force will push the weight up, thus making it afloat.
Children went around the classroom, took any materials that is in the classroom. They predicted and experimented if the materials sink or float.
The toy spectacle floated!
The feather floated!
The ruler actually sank after Nicole pushed it into the water!
The pencil sank!
The toy stethoscope floated!
The empty water bottle floated!
The children's clock floated!
The children also experimented with a flat piece of aluminium foil and discovered that it sank. Then they formed the flat piece of aluminium foil into a boat and discovered that it floated! Amazing!
Air Transportation
How does an aircraft flies in the air? It needs weight, lift, thrust and drag to enable them to be in the air. Children predicted and experimented with closed and open parachute to see which dropped to the ground faster.
Indeed it's the open parachute will stay longer in the air as it traps air within it! It's a new learning we had. Let's experiment with that at home too, Mum and Dad!
