Lesson Title: How Do I Live: Plant Life Processes
Time Required: 50 mins
Instructional Performance Objectives
Overall Objective: Students will be able to describe the life processes of plants with 85% accuracy as
determined by a teacher made rubric
Enabling Objectives:




explanation of the process of photosynthesis using the formula for photosynthesis
explanation of the process of respiration using the formula for respiration
identification of the chemical compounds involved in photosynthesis and respiration
explanation of the importance of photosynthesis and respiration to both plant and animal life.
Standards of Learning:
English
7.6
The student will read and demonstrate comprehension of a variety of nonfiction texts.
Use prior and background knowledge as a context for new learning.
Use text structures to aid comprehension.
Identify an author’s organizational pattern, using textual clues, such as transitional words and phrases.
Draw conclusions and make inferences about explicit and implied information.
Differentiate between fact and opinion.
Identify the source, viewpoint, and purpose of a text.
Describe how word choice and language structure convey an author’s viewpoint.
Identify the main idea.
Summarize text identifying supporting details.
Identify cause-and-effect relationships.
Organize and synthesize information for use in written formats.
Use reading strategies to monitor comprehension throughout the reading process.
Mathematics
1
7.4
The student will solve single-step and multistep practical problems, using proportional reasoning.
Science
LS.3
The student will investigate and understand that living things show patterns of cellular organization. Key
concepts include
cells, tissues, organs, and systems; and
patterns of cellular organization and their relationship to life processes in living things.
LS.5
The student will investigate and understand the basic physical and chemical processes of photosynthesis
and its importance to plant and animal life. Key concepts include
energy transfer between sunlight and chlorophyll;
transformation of water and carbon dioxide into sugar and oxygen; and
photosynthesis as the foundation of virtually all food webs.

Teaching Tips/Strategies
1. Introduction: (5 mins)
a. We all have to carry out basic functions to
keep our bodies up and running.
Can you name some of these functions? (12 mins on the question)
Write student responses on the board
-Make sure that eating, breathing get
mentioned
b. Plants have to carry out similar functions to
keep them going. However, about more than
just keeping going. Plants have the ability to
manufacture sugars and starches.
Turn to your neighbor and brainstorm what
do you think plants need to do in order to
live and produce the sugars and starches?
Be prepared to share. (1-2 minutes for
collaboration on answers)
Write student responses on the board
As we go through the lesson today think
about how these relate to the functions we
go through to keep our bodies going?
2. Photosynthesis (15 mins)
a. What is the definition of photosynthesis?
Can someone define for me what
photosynthesis is?
i. Photosynthesis is a chemical change
that produces food in green plants.
ii. During photosynthesis, carbon
dioxide, gas, and water are
combined to produce sugar.
iii. Sunlight supplies the energy for the
chemical change.
b. Why is photosynthesis important?
i. It is the most important chemical
process in the atmosphere.
ii. It allows plants to make their own
food.
iii. It provides oxygen for animals.
iv. It makes complex sugars, starches,
fats, and proteins.

c. What elements are necessary for
photosynthesis?
Can any of you list some of the elements of
the photosynthesis equation?
i. CO2 = carbon dioxide
ii. H2O = water
iii. light = sunlight
iv. chlorophyll = green in plants
v. C6H12O6 = sugar (glucose)
vi. O2 = oxygen
d. What is the equation for photosynthesis?
Which of these are the products of
photosynthesis and which are the
ingredients?
i. 6CO2 + 6H2O +light  C6H12O6
(sugars) + 6O2
3. Respiration (15 mins)
a. What is the definition of respiration?
If photosynthesis is the process by which
plants make food, can someone tell me
what they think respiration is?
i. Respiration is a process by which
living cells take in oxygen and give
off carbon dioxide.
b. When does respiration occur?
We know photosynthesis requires sunlight,
so it occurs during the day. Do you think
respiration has limits on the time of day it
occurs? Can someone give me a guess?
i. Respiration occurs during both day
and night.
c. What is the formula for respiration?
i. C6H12O6 + 6O2  6CO2 + 6H2 O +
heat
d. Why is respiration important?
So what? Why do plants need to respire?
What do they do in addition to giving off
CO2? Can anybody guess?
i. Respiration uses the sugars and
starches produced by
photosynthesis and converts them
into energy.

4. Making connections/Conclusion/Assignment (5
mins)
In the beginning we discussed what we thought were the
basics necessary for us to live and then we covered the
absolute basic functions plants need to keep themselves
running. We also mentioned that plants produced starches
and sugars. For homework I want you to consider the
following questions and write a 1-2 paragraphs that
describes the connection between plants and animals.
How do plant products connect plants and animals?
Of what value are plants to people?
What would life be like without plants?
Are there benefits for plants as well?
Any questions about the assignment?
5. Review (5 minutes)
What is photosynthesis?
What is respiration?
How are the life processes of plants similar to animals?
What makes respiration in plants different from the same
process in animals?
