Learning Tasks: A. Engagement: 1. Say: “We just studied about different kinds of animals living in land and water. Do we find plants growing in land and water too? 2. Take the pupils around the school grounds and make them list/ name and draw plats they see. One plant per pupil is enough. If you have a pond or an aquarium, take them there as well and ask them to draw one plant.

3. Elicit their answers or gather their drawings. Consolidate or group the names/drawings into those that grow on land and those that grow on water. 4. Prepare a table on a manila paper similar to the one given below. 5. Ask the pupils to write their answers on the manila paper.

B. Exploration: 1. Inform pupils that they will do an activity in a place assigned to them. 2. Remind the pupils to observe proper behavior as they perform individual and group tasks. 3. Ask the pupils to do Lesson 27: LM Activity 1: “What is it?” 4. After all have finished the activity, ask pupils to go back to their classroom. C. Explanation: 1. Ask a group member to present the groups result and answer the guide questions.  What is common to all plants? (leaves, roots, stems and flowers)  Do the plants have the same stem? (No, plants have different leaves, some leaves are narrow, others are wide)  Do the plants have the same leaves? (No, they have different leaves. Some leaves are narrow, others are wide.)  What new things have you learned about the plants? (Plants have different characteristics). (They differ in size. Some are small, others are big.)  Do these plants grow on land? (Yes they do)  But some grow on water as shown in the table. 2. Lead the class to state this: We call plants that grow on soil terrestrial plants and those that grow on water aquatic plants. Some terrestrial plants are small, others are big. There are plants with big trunks while others have soft stem. Terrestrial plants grow in different places. There are plants that grow directly on soil while others grow on rocks. Aquatic plants live within watery environments. In the ecosystem, aquatic plants serve as food and habitat for animals living in the sea and prevent shorelines, ponds, and lakes from encoding by providing soil stability. D. Elaboration: 1. Say: They have parts in common but certain structures enable plants to function under certain conditions. 2. Let the pupils state the commonalities and differences and the inferred functions. Pupils should be allowed to infer the functions of the specialized structures and confirm pupils’ answers against scientific viewpoints Say:

Plants living in different places are exposed to varied conditions however; their structures are suited to particular needs. For example, forest plants tend to grow tall and sturdy. Shapes and sizes of the leaves are also important for survival. Plants like bananas produce big, broad leaves to efficiently trap more energy. Plants with waxy leaves help to protect themselves from dehydration as a result of too much exposure to the sunlight, Some plants have also developed structures to store water especially in the dessert. Cactus is the best example of desert plant. Roots of the plants adapt themselves too their habitat. They differ in sizes and shapes too. These characteristics are determined by their functions. E. Evaluation: List down all the common names of the plants actually selected by the pupils during the activity. Let them group as to terrestrial or aquatic. IV.

Assignment: list other terrestrial plants can be found at home.
