Unit Topic: Earth Science
Grade: 3
Lesson Plan Topic: Photosynthesis
Lesson Objectives: Students will be able to list or draw
the three main
nutrients that all plants need in order to go through
photosynthesis.
Instructional Technique: class discussion,
online group work,
experiment
Instructional Materials: “Photosynthesis
Online Guide”
Handout, computers
https://www.scholastic.com/magicschoolbus/games/sciencenews/loader_2.swf. For our closing
activity:
biodegradable pots, seeds, dirt, water.
Theoretical Perspective: This lesson is
important for
students to know because students should have a basic idea of
the planet and
what makes plants grow. This will also help them learn how to
care for plants.
Procedure
A.
Introductory
Teacher will call students to circle up at the
front of the
room.
Teacher will ask multiple questions about
plants and record
students answers on the board.
● What do humans need to
survive?
● What do animals need
to survive?
● What do you think
plants need to
survive?
● What do you think
Photosynthesis
means?
B. Main Lesson
Teacher will instruct students to work in
groups of two or
three and get a computer to share. Then the teacher will handout
the
“Photosynthesis Online Guide” handout. On the handout will be
instructions on
how to get to the website and then what to do once you are on
it. The students
will then go onto the website and follow the animation. On the
handout the
students will answer questions based off of the photosynthesis
game on the
website. For example a question would be “where does a plant get
Carbon Dioxide
from?”. The students will be instructed to go through the
website twice so they
can test if different plants need the same nutrients. Lastly,
the students
will draw out the
cycle of the
photosynthesis to get a visual of what they believe this process
might look
like.
C. Closure
At the end of the
lesson, the class
will come together to discuss what they received for answers and
to show their
drawings to see if they are similar to the actual cycle of
photosynthesis.
After the teacher and students have gone over the worksheet the
students will
be told to go back in their groups, each group will be handed a
biodegradable
pot and a seed; each group will have a different type of plant.
Within each
group they will be instructed to plant the seed then add water.
After they
plant their seeds and added water, one person from each group
will place their
plants in front of a window and will observe the growth of their
plants for a
week.
D. Adaptations
For students who work quickly and
want to be further challenged, there is an option for them at
the end of the
worksheet to continue learning about photosynthesis in the
“Facts” section of
the website.
ELL students can be grouped with the teacher
or paired with a
strong reader who can read the information on the website
outloud.
There
is a variety of
questions on the guide and ways students can express their
learning. For
example we have provided the option for students to draw a
picture of their
plant and how it got its nutrients.
E. No homework will be given
Evaluation
A. Our objective was: Students will be able to list or draw the three main
nutrients that all
plants need in order to go through photosynthesis.
Students are asked to draw the cycle of
photosynthesis on the
back of the work sheet. The teacher will look to make sure there
is a plant
dawn with three arrows pointing to it. At the top of each arrow
should be
water, sunlight or CO2.
On
the
worksheet students were also asked to list the three nutrients
plants need to
go through photosynthesis. They should have listed water,
sunlight and CO2.
Students
were
asked to repeat the process of “growing a plant” twice in order
to help them
understand that most plants need those three nutrients.
B. Concerns
A
concern that a teacher might have is some of the student’s might
not fully
understand the cycle of photosynthesis by the end of the lesson
and will still
have questions by the end.
Another concern might be that students lose
focus with the
activity or that some finish the activity much faster than
others and become
bored or not continue onto the “facts section.”
