Alabama Course of Study 7.) Describe the life cycle of plants, including seed, seed germination, growth, and reproduction. • Describing the role of plants in a food chain • Identifying plant and animal cells • Describing how plants occupy space and use light, nutrients, water, and air • Classifying plants according to their features Examples: evergreen or deciduous, flowering or nonflowering • Identifying helpful and harmful effects of plants Examples:- helpful-provide food, control erosion;- harmful-cause allergic reactions, produce poisons • Identifying how bees pollinate flowers • Identifying photosynthesis as the method used by plants to produce food COS across grade levels

Plant Growth and Development Table of Contents # Lesson Title Date 1 Plants KWL

Brainstorm everything you know (or think you know) about plants. Date Lesson 1: Plants KWL Question: What do you KNOW about plants? Be sure to use this time to set up notebook for plant growth and development kit. Table of contents and Index should be started on this day. How much information does the students already have? Have the students had previous experience planting, transplanting, pollinating, harvesting, or threshing? Brainstorm everything you know (or think you know) about plants. Pre Unit Assessment

Brainstorm everything you wonder about plants. Question: What do you WONDER about plants? Be sure to use this time to set up notebook for plant growth and development kit. Table of contents and Index should be started on this day. How much information does the students already have? Have the students had previous experience planting, transplanting, pollinating, harvesting, or threshing? Brainstorm everything you wonder about plants. Pre Unit Assessment

What type of scientists are we? We are botanists! Scientists that study plants.

Observe the dry bean seed. Inside Participant’s Guide TH-3 Write one or two words to describe the seed you are observing today. Observe the dry bean seed.

Activity Sheet 1, continued… Draw your dry bean seed. Draw and label the inside of your soaked bean seed What will happen to the seeds if we soak them in water overnight?

Lesson 2: Inside a Seed 1. Question: What is inside a seed? Date Lesson 2: Inside a Seed 1. Question: What is inside a seed? 2. Hypothesis: If I open a seed, then ______________________. Draw an illustration of your prediction. Lesson 1

4. Data: Continue Activity Sheet 1 3. Plan: Examine and record observations of the soaked bean seed using a hand lens and loupes. 4. Data: Continue Activity Sheet 1 For each student: 1 dry bean seed 2-3 soaked bean seeds Hand lens 1 paper towel

Observe the soaked bean seed. Write one or two words to describe the seed you are observing today. Observe the soaked bean seed.

How is the soaked bean seed different from the dry bean seed? STC Plant Growth and Development Lesson 2: What Is Inside a Seed? How is the soaked bean seed different from the dry bean seed? ©2003 Microsoft Corporation.

STC Plant Growth and Development Lesson 2: What Is Inside a Seed? Now peel off the seed coat. Gently pry open the two halves of the seed. Use your hand lens to observe the parts of the seed.

Activity Sheet 1, continued… Draw your dry bean seed. Draw and label the inside of your soaked bean seed

STC Plant Growth and Development Lesson 2: What Is Inside a Seed? Take another soaked bean seed and observe it closely, inside and out. Are the two bean seeds similar? ©2003 Microsoft Corporation.

Model of a Bean Seed Inside a Bean Seed TH-4 Embryo: undeveloped plant that includes all the parts of a mature plant. baby plant Cotyledon: Contains food- oils, carbohydrates and protein. This provides energy for the initial underground growth of the plant. Becomes the seed leaf. Lesson 2: 3 parts of a seed: Embryo: undeveloped plant that includes all the parts of a mature plant. baby plant Cotyledon: thickened leaf that starts food. Contains food- oils, carbohydrates and protein. This provides energy for the initial underground growth of the plant. Seed coat: protects these delicate internal structures. Cardstock Seed coat: protects these delicate internal structures. Waxed paper

Some Questions to Ponder Are all seeds the same? What would happen if we planted our seed? What kinds of seeds do we eat? Lesson 2: 3 parts of a seed: Embryo: undeveloped plant that includes all the parts of a mature plant. baby plant Cotyledon: thickened leaf that starts food. Contains food- oils, carbohydrates and protein. This provides energy for the initial underground growth of the plant. Seed coat: protects these delicate internal structures.

Possible Extension Idea: “Grass Babies” Materials: knee high panty hose, soil, fast growing seeds – fescue, eyes, hot glue gun, and a rubber band. Place seeds at the toe of the hose, fill with soil, make ears and nose with rubberbands, and tie off the end with another rubberband. Water well! The “Grass Babies” are made with a knee high panty hose, soil, fast growing grass seeds such as fescue, eyes, hot glue gun, and a rubber band. Pour at least a tablespoon of grass seeds in the toe of the panty hose, pack soil in next, tie with a rubber band. Using a hot glue gun, glue the eyes on the head. Place the bottom party of the panty hose in a plastic cup and let them sit in a sunny window. Within a few days the grass seeds will sprout and after a while the students can give their grass babies a haircut! The picture above shows the grass baby in the top of a washing detergent top. Those are pretty sturdy, but not as easy to obtain.

Science Notebook EVALUATIONS Make it very clear to your students that you are evaluating their science notebook entries for: Clarity: descriptions are clear and precise Completeness: all parts of the seed are observed and described Accuracy: drawings should be as close as possible to the real thing Appropriate use of vocabulary: incorporate newly acquired words into written observations and label parts correctly
