standing in front of the class

Today,I was standing right in front of the class telling them about the leaf that I found. I was the first few to introduce.

I told them,”I found this leaves in the car park near my house. This leaves come from Senegal mahogany. It is one of the top ten known well tree in Singapore. The tree is always straight and has a large bushy crown. The upper side of the leave is dark green while the underside of the leave is light green. We classify this as a leave because it has leave veins,leave blade,leaf stalk.”

I found that by doing this it will let us learnt more about the different types of leaves and able to speak clearly in front of the class without getting nervous and scared.
