TN COMPONENT OF SCIENCE:Unifying Concepts of Science
BENCHMARK: Offspring may resemble their parents, but individuals within a general population may vary.
(Have on hand for each child, one washed half-pint milk carton with top cut off, soil, spoon, cup and water. Cut the tops off the milk cartons and wash them. Punch four holes in the bottom to allow for drainage. Label the cartons with each child's name, the kind of seed, and the date of planting.) Each of you are going to plant some seeds in the soil. Plants need SOIL to grow. (Help children plant seeds) Now, we are going to take a seed and put it in a carton without soil. What do you think will happen to this seed? (response) We are going to watch this seed carefully and record what happens. (Plant two extra seeds for other experiment.) (Plant two or three seeds in a Ziploc baggie. Students will be able to observe the "underground" happenings as the seed grows.) (After the children have planted their seeds, put out a watering can.) Plants also need WATER in order to live. You will need to water your plant today. Over the next couple of weeks, you will need to feel the soil. If it feels dry, water it. Be careful and do not put too much water on it. (Put an X over rain drops on one of the extra planted seeds.) We are not going to water this seed. What do you think will happen to it? (Record their predictions to compare later.)
(Have the students put their planted seeds in a sunny window.) Why did we put our seeds in the sunlight? (response) That's right! Plants also need SUNLIGHT to grow. (Take an extra planted seed. Put a sun with an X over it on the carton.) We are going to put this plant in our dark closet where the sun doesn't shine. What do you think will happen to it? (record responses.)
A plant is a living thing, just as you and I are. Plants, like us, also need air in order to live. Tell your partner four things a plant needs in order to grow. (response) (Make a chart titled "What Plants Need In Order To Grow". List and illustrate with your students help.)
Over the next two weeks, we will be watching our plants closely to see how they grow and change. Today we started with a seed. We are going to keep a photo journal of the growth of a plant. That means that we are going to take pictures of our plants as they grow. (Take a picture of a seed or draw a picture. Write a sentence or two explaining the picture.) I am giving you each a seed to examine closely. (Give each student a seed that has been soaked in water overnight.) Carefully, slip your seed out of its covering. That covering is called a coat. It helps protect the seed. Now, carefully open your seed. Look closely. Can you see a baby plant? (response) A baby plant is in every seed. The seed sprouts and a little plant begins to grow. (Go around and help each student find the plant.)
2. Have students illustrate and write their own stories.
3. Start a seed collection at school. Have students collect seeds from foods at home and bring them to school.)
4. (After plants have begun to grow, ask your students,) "Do you think your plant is hungry? (response) Should I give it a cookie? (No!) A hamburger? (No!) Well then, how does your plant get food? (Allow students to investigate this overnight. Continue the discussion the next day. Take the children's responses, then explain that plants make their own food by using water, light, and some things from the soil called minerals. The plant's leaves are a food factory.)
5. (This is a good time to read and act out "Jack and the Beanstalk."
6. Sing the song, "I'm a Little Bean Sprout" to the tune of "I'm a Little Teapot".
