Hello, I'm Kaaviyan a student in Australia, Victoria. I'm going to talk about the process of photosynythesis.

Photosynthesis is the process of plants taking carbon dioxide and turning into oxygen. For this to happen the plant needs food, sunlight and water. The food gives the plant energy to carry the water around the leaves. The sun light joins the water in the leaves to make the chlorophyll. This releases the oxygen and makes sugar to make more leaves. That is the process of photosynthesis.

Newton's Cradle

The Newton's Cradle was invented by Sir Isaac Newton. The Newton's Cradle demonstrates the force travelling through a few identical balls. The balls suspend from strings hanging onto the cradle. It works when the ball on one end is let go, the force makes energy and the energy travels through the balls in the center and goes to the other ball and continues without ending. This is the science of force and motion.
