Victoria amazonica, the leaves of this plant grow up to 3 metres across. A mature Victoria leaf can support an evenly distributed Load of 45 Kilograms or apparently young person.




Activity 3

The teacher will divide students into four groups. Each group leader will pull a plant part from a “hat” (roots, stems, leaves, and flower). The teacher will take students around campus to search for their assigned plant parts. They have to locate different types of plants discussed in the class room. The learner will return to the class, follow a process sheet given to create a poster with their group and identify correctly each type of root, stem, or leaf observed. The flower group will create a poster by identifying correctly each part of the flower. Each group will share their posters within the class.


Activity 4

Read the following story along with your friend

Once, I was a happy monkey. I lived in a beautiful thick forest with my mother and two brothers. We ran and played in the lush grass. On one hot day, I fell fast asleep in the cool shade of a tree. Suddenly the bright sun woke me up. I opened my eyes and could not believe what I saw everything has changed. Everything had been destroyed. I stood and looked at the stumps that used to be trees. Nothing was left apart from hard dry ground and only streets and building

I saw a deer that looked very sad, “where have all the trees gone and where are all the other animals?” I asked her. She explained how humans had chopped down all the trees, but had not planted new ones to replace them. After a while, I said good bye to deer. My home had gone. I didn’t know where my family was, and I was starting to feel hungry and thirsty, day and night. I walked in search for water, food and safe place to sleep. Whenever I stopped, to rest humans drove me away with sticks and angry voices. I could feel my body getting weak and tired. One day when I had almost given all the hope, I came across a cool and dark forest. As I walked through it, I found plenty of food and water. The forest felt safe for me. There were no signs of human visiting it.
