I.OBJECTIVE:Perform experiment to determine what plants need to make food.

Values:Industriousness, cleanliness and sanitation

II.SUBJECT MATTER:What Plants Need to Make Food

A.Science Concepts/Ideas:1. Tropism - plant responses a. Phototropism - response to light b. Hydrotropism - response to water c. Geotropism - response to gravity 2. Photosynthesis - the synthesis of chemical substances with the aid of light especially the formation of carbohydrates; producing their own food.

B.Processes:Observing, describing, experimenting, comparing

C.Materials:Mongo seedlings in 4 separate cans, water, box

III.PROCEDURE:A.Preparatory Activity:Checking of Assignment Review:1. What are the classifications of living things? 2.How do they differ from each other?3.What do plants need in order to grow?

B.Developmental Activities:1.MotivationWhat do animals need in order to grow? How about plants?

2.Presentation/ActivityGroup the children into four. Each group will plant a mongo seedling in a can labeled A, B, C & D. Water can A regularly. Do not water can B. Place both cans where there is ample air and light. Label C & D two other cans of mongo seedlings. Place C in the light and D in a closed box. Water both cans regularly. Observe the growth of the seedlings daily for two to three days. There are two set ups in each experiment. The experimental set up and the control.

3.Concept FormationEach group will present their report. What are the factors needed in plant in order to grow? Describe the growth of the seedlings. How can these variables help by plant growth?

4.ApplicationWhat do plants need to grow and stay alive?

IV.EVALUATION:Answer the following questions: 1. In which can or cans are the seedlings healthy? 2. Describe the growth of each. 3. What is the manipulative variable in can # 1? can # 2, can #3 and can # 4? 4. What are the constants?

V.ASSIGNMENT:How do plants respond to water?
