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

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 Grow
Day 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 BUDS
DAY 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.
