CONCEPT: Plants are living things with specific needs, characteristics and uses.
CONTENT OBJECTIVE: 1Fl.OO To understand the basic needs of all plants
INSTRUCTIONAL OBJECTIVES: The learner will:
1.01 demonstrate that plants need water, air, minerals, and light to make their own food.
OUTLINE OF CONTENT:
I. Plants need water
II. Plants need air
III. Plants need light
IV. Plants need minerals
TN COMPONENT OF SCIENCE: Unifying Concepts of Science
To enable students to acquire scientific knowledge by applying concepts, theories, principles and laws from life/environmental, physical, and earth/space science.
2.5 CHANGE - Interactions within and among systems may result in changes in the properties, position, movement, form, or function of systems.
TN STANDARD(S): The learner will understand that:
2.5a Everything is constantly changing; rates of change vary over a wide scale with a great variety in patterns of change.
BENCHMARK Some things may stay constant while others change.
2.5b Cycles of change can be extended in scales of time, space, and material.
BENCHMARK Changes occur in various ways and may be altered by controlling some variables.
45 minutes - 1 hour (one week for observation of plants)
Plants, water, chart paper, slates
Boys and girls, today we will be discussing the four basic needs of a plant. How many of you have a vegetable garden or a flower garden at home? (response) Have you ever helped plant or take care of the garden? (response) Let's discuss some things that will help garden plants be healthy and bear flowers and vegetables.
(Have plants in classroom for children to observe.) Plant need special care in order to help them grow. Plants need soil, air, light, and water. Some plants grow indoors. They also need soil, air, light, and water. Plants need to be fertilized regularly to help them grow. The fertilizer has certain minerals in it that help keep a plant healthy. If you have noticed the growth of the plants in the classroom, you will be aware that most of them are larger at the end of the year than at the beginning of the year. Have you noticed that plants close to the window tend to grow toward the light? (Yes) Yes, they do.
Let's try an experiment. We will place one plant in the light without water, one in the dark with water, and one in the dark without water. Where do you suppose the plant is getting its food? (Sun and water) Let's make a chart on paper and record what happens to each plant.
CLOSURE AND INDEPENDENT PRACTICE:
We have discussed plants and their needs. On your slates, list needs of all plants. At the end of the week, we will turn in our charts of the plants.
