Modelling Pangea Stage-9 Science Activity

 

Pangaea is a supercontinent to have existed and the first to be reconstructed by scientists. Learners of stage-9 made a model of Pangea. Learners had an outline of world map. They cut out the shapes of the main continents. Experimenting with the arrangements of the continents to make pairs of the continents fit together. They investigated whether it is possible to make all the continents fit together to suggest what Pangea looked like. The activity made learners much more clear about the concept of supercontinents. 

Investigating, If speed of an object is affected by height of ramp Stage-8 Science Activity

 

Learners of Stage-8 investigated the speed of a Tennis Ball by keeping distance same and measuring time. In this investigation learners used colored tape to fix the bottom of the ramp to the desk or floor.

Fixed some colored tape 1 m from the end of the ramp. Fixed some colored tape near the top of the ramp to mark where you will release the ball. Measured the height from the desk or floor up to the position where you will release the ball. Released the ball and measure the time the ball takes to move between the two pieces of colored tape on the desk or floor. Repeated this two more times and calculate the average time to travel between the two pieces of tape. They did this for a range of different heights.

They calculated the speed of tennis ball at different heights.

The Activity made learners more clear about the ideas of speed and average speed.
