Let%u2019s Discuss CommunicationDiscuss in class how the process of photosynthesis takes place in plants.Let%u2019s Do Experimental Learning%u2022 Take two leaves, one green and the other yellow or red.%u2022 Boil them in water. Then boil them in spirit and wash with cold water.%u2022 Now add a few drops of iodine.%u2022 You observe that the green leaf turns bluish-black but the other leaf does not show any change.%u2022 This activity shows that only the green leaf that had chlorophyll could make food but the other leaf could not.Let%u2019s do an activity to show that chlorophyll is necessary for photosynthesis.Let%u2019s Explore Experiential LearningLook around and observe the plants and trees. Are they growing bigger by the day? Do they have healthy leaves and branches? Do they get enough water and sunlight to make food?Let%u2019s Have Fun Art and CreativityPaste pictures of roots, stems, leaves, fruits and flowers that store food.Let%u2019s Learn Life Skills and ValuesWe must take care of plants so that they can live and grow. Water the plants regularly. Do not pluck leaves, flowers or twigs. The plant needs them.Arrow-Puffin-4_Semester-1 Science 229
