I.OBJECTIVE:Classify plants into major groups: flowering plants, cone-bearing plants, ferns and mosses.

Values:Appreciation of the usefulness of plants; Caring of plants; Cooperation in group activities

II.SUBJECT MATTER:Classifying Plants

A.Science Concepts/Ideas: Plants maybe grouped into flowering (angiosperm) and non-flowering (gymnosperms or conifers) Flowering plants bear flowers while non-flowering ones such as ferns reproduce by spores. Moses are called bryophytes. They are non-vascular plants.

B.Processes:Classifying, describing

C.Materials:Sample of flowers and fruits, pine branch with cones, fern, moss

III.PROCEDURE:A.Preparatory Activity:Review the different parts of a flower

B.Developmental Activities:1.MotivationAsk this question: Do all plants bear flowers? Let the pupils work on activity 3.11 p. 105 of Into the Future: Science and Health, discuss their answers in class.

2.Presentation/ActivityForm 4 groups. Each group will perform specific activity.

Group 1 Examine the flowering plants. Answer the flowering plants. Answer the following questions: Do all flowers have bright colored petals? Do all flowers release pleasant colors? Where do seeds of flowering plants come from?

Group 2 Examine the underside surface of the fern leaf (or frond).Answer the following questions: What do we call these dark brown cases? What do they contain?

Group 3 Examine the cone-bearing plants. Answer the following questions: What do cones carry? When those male and female spores unite, what do they form?

Group 4 Examine the Non Vascular Plants Answer the following questions: How will you describe the structures of non vascular plants? How are food and water transported to different parts of the body?

3.Concept Formation Each group will present their findings. Make conclusions regarding their activity. Teacher may ask questions that may lead to the conclusion how do flowering, fern, cone-bearing and nonvascular plants live?

4.Application Let the pupils refer to the Going Further Section of the book. Point out why it is important to classify plants. Ask: How are we going to take care of these plants?

Which reproduces through spores? a. pine tree c. orchid b. rose d. ferns 3. Which plant does not belong to the group? a. mosses c. macopa b. corn d. mango

V.ASSIGNMENT:Identify the characteristic of certain plants.
