PLANT GROWTH &DEVELOPMENT By: Lori Mitchell
To Know a Plant,Grow a Plant • Plant a seed • In the mind and with the hand • Use the five senses • To engage and understand • To investigate; observe, • Measure, analyze, and describe… • Harvest a Fast Plant seed • And make science come alive
M & M Color Code • Tell one job-related fact for every red you chose. • Tell one family fact for every green you chose. • Tell one thing you like to do for every blue you chose. • Tell one movie you like to see for every brown you chose. • Tell one book you like to read for every yellow you chose. • Tell one place to which you would like to travel for every orange you chose.
Let’s Take A Walk • STC Introduction • Overview • Materials • Science Notebooks • Science Course of Study • Lessons • Lesson Duplication Masters. • Assessment • Learning Cycle • Assessment Duplication Masters • Resources
What Do You Know About Plants? • In your science notebooks make a KWL chart and list the things you know, and want to know about plants. • Write one of the things you know on the leaf provided.
OBSERVING LIMA BEANS • Turn to your Table of Contents and add Seed Observations. • Gather materials: 1 dry lima bean, 1 hand lens, activity sheet 1 • Complete the chart by writing one or two descriptive words in each of the first four blocks (Color, shape, texture, and odor) • Make a drawing in the last block. “Size” • Measure it with a centimeter ruler. • Place your bean in the medicine vial filled with water.
PREDICTION • Using your science notebook make a predication about what will happen to the beans after soaking overnight. • After my lima bean soaks overnight, I think it will__________ because….
SOAKED BEAN • Gather materials • Complete the chart • State your conclusion • Did anything surprise you? • Is there anything new you would like to learn? • Would all beans do the same thing?
What is Inside a Seed • Gently peel off the seed coat. • Pry open the two halves • Do you see the embryo and the cotyledon • Make sure you are using your handlens. • Add “What is Inside a Seed” to your science notebook • Draw and label the parts of a seed. • Compare your drawing to the transparency.
Planting the Seeds • What are a plants basic needs. • WATER, LIGHT, NURISHMENT, SPACE • How will we provide these for our plants? • WATER. (WATER SYSTEM) • LIGHT (LIGHT KIT) • NURISHMENT (SOIL and FERTILIZER) • LET’S PLANT • Now let’s read Fast Plants for Fast Times
SCIENCE NOTEBOOK • Add: Planting the Seeds to the TABLE OF CONTENTS. • Question: What do plants need to survive? • How will we provide these needs? • On the vocabulary page add: germination
THINNING AND TRANSPLANTING • Question: Why must we thin and transplant? • Think about a plant’s basic needs. What needs cannot be met if a plant doesn’t have enough space? • Choose the healthy plants to stay. • Keep one plant per cell. • Loosen the soil around the plants. Remove the plants carefully. Use a handlens to examine your plants.
ROOTS • Look for the roots and root hairs. • Draw your uprooted plant in your science notebook. • Write down your answer to the question why must we thin and transplant • Did all of the seeds sprout or germinate?
COMIC STRIP • Make a comic strip using 2 plants in the same pot or quad as the main characters. • Have one try and convince the other to move out. • Make sure you include in the strip valid reasons for one plant to move out
PHOTOSYNTHESIS • Add photosynthesis and germinate to your vocabulary
How Does Your Plant GrowDay 5,6,7,or 8 • Select one plant to measure everyday • Put your label next to that plant • Measure your plant in centimeters. • Graph and record your data
OBSERVING LEAVES AND FLOWER BUDSDAY 7,8,or 9 • Observe your quad with a hand lens • Look closely at the leaves • Are they all alike • The bottom two are seed leaves. They were the cotyledon while inside the seed • The next are the true leaves
Notice the color, size, shape, and number of buds. • Count the leaves. (Both seed and true) • Now make a scientific drawing of your plant. • Label the parts. • Write a several descriptive sentences about your plant • Look at the life cycle cards. Compare the cards with your plant.
PREDICTION • What will happen to your plant next? • Add to vocabulary: seed leaves, true leaves, flower buds.
