Teacher's Guide
Unit One : Plants Elicit students to identify plants by asking them about the shapes, colors and make them draw a plant or a single leaf. Ask students questions about the boy in the picture: What is he doing? why is he watering the plant? Make a list of 5 common names of plants in the country and do a a brainstorming on the board.
1. Petiole It is the stalk that connects a leaf to the stem of the plant, it is made of complex conducting tissues called vascular tissues. 2. Leaf Base It is the lowermost part of a leaf, which is closest to the petiole. 3. Leaf-blade or Lamina It is the thin, flat part of the leaf that is typically green in color. It is further divided into three parts: i) leaf apex – the tip of the leaf blade, ii) leaf margin – the edge of the leaf and, iii) leaf veins – the small channels or capillaries, which are further subdivided into venules.
Explain Ss the main parts of a leaf. Work with them with pronunciation. Elicit them to complete the next activity.

Elicit Ss to think about the consequences of not watering the second flower pot.
Doing plant experiments and sprouting seeds with young children in the spring. Not only do they get excited to see how plants grow but planting seeds also teaches them patience and how to wait for gratification which is very important in this fast-paced, instant gratification world in which we now live. What Liquid is Best for Growing Seeds? Experiment This experiment tests what type of liquid is best for growing seeds and can be done using a wide variety of liquids. Since we already discussed that plants need water to grow, we first tested different types of water to see if it made a difference. You can decide to test tap water, bottled water, sugar water (1 cup of water with 1 Tbsp sugar), and salt water (1 cup water with 1 Tbsp salt). You can also grass seed for this experiment because it sprouts fairly quickly but you can use bean seeds (lima beans soaked overnight in water work well) or any other type of seed you wish.
