Science,
learning about autumn and leaves
Grade: 2nd
Grade
Lesson Topic or Theme:
Today's lesson topic is on, Why Do Leaves Change Color
in Autumn?
Lesson Objectives: The students
will be define the process of photosynthesis and how it
connects to why and how the leaves change color in the
fall. The student will be able to identify different
leaves by color, shape and size.
Instructional Technique: In the
beginning of class, the teacher and students will be in
an interactive discussion on the leaves that were
brought in by the students (last nights homework
assignment).
The students will then work
independently on the scavenger hunt worksheet/reviewing
and reading through the website.
There will be group discussion
based on what they learned and found as answers for the
scavenger hunt.

Theoretical Perspective:
This lesson
will teach the students the concepts of why and how the
leaves change color in the fall. This is important part
of learning about science and how different seasons
cause different reactions from the environment around
us. They will learn that the changes in the length of
daylight and changes in temperature causes the leaves to
stop their food-making process, photosynthesis. The
chlorophyll breaks down, the green color disappears, and
the yellow to orange colors become visible.
Procedure:
The teacher and
students will work on a science activity today. The
science activity will introduce why the leaves change
color and how they can change their color. This lesson
is to introduce the classroom to the season of fall. The
class with be able to visualize the leaves, sort them
into groups and then work independently on an online
website which goes into further detail of how and why
the colors of leaves change in the autumn. While reading
and viewing the website, the students must fill out a
scavenger hunt worksheet, which the students must fill
in the blank sentences that are listed.
A. Introductory Activity (if
applicable)
Today we get
into learning about how leaves change their color and
why they change color. The students had homework last
night which was to find one leaf and bring it to class
today.
When the
students arrive into class they will bring the leaf that
they brought in to their desk. As the students are at
their desk with their leaf, the teacher will pass out
the leaf investigation worksheet where the student must
fill out based on the leaf they choose to bring in.
After the
students fill out the worksheet, the teacher will ask
the students to bring up their leaf by table to the
whiteboard. At the whiteboard, the teacher will help the
students tape up the leaves so the whole classroom can
see all the different types that were brought into
class.
As a class, we
will go over the leaves that are presented. The teacher
will make columns to represent, size(big, medium, small)
and color(red, green, yellow, orange, brown). As a
class, the students and the teacher will discuss the
different types of leaves and decide what leaves are
similar and which ones are different.
B. Step-by-step (descriptive
outline)
After the
class notices and visualizes the different groups of
leaves, the teacher will then handout the scavenger hunt
worksheet. The teacher will allow each group of tables
go one at a time to retrieve the laptops. On the
worksheet there is a website that they will use in order
to find the answers for the scavenger hunt. Some
students may need more assistance than others with going
onto the website. The teacher should walk around the
room to make sure all the students are on the correct
website. The Students will then work independently while
completing the scavenger hunt worksheet and should only
be on the website given in the instructions. While the
students are working, the teacher should be walking
around the classroom to help assist students, answer any
questions and to make sure they are working
independently on this activity.
C. Closure
After the
students finish the scavenger hunt worksheet and have
read through the website, they will discuss with their
groups about their answers and what they learned. When
they have discussed their findings and their answers,
they will then hand in their work to the teacher.
D. Adaptations for different
learners
Google translate
Pair the student(s) who is a weak
reader with a student who is a strong reader
E. Homework
No homework
Evaluation:
A. How/when will you determine if
you have met your objectives?
The students will be define the
process of photosynthesis and how it connects to why and
how the leaves change color in the fall.
To document this objective’s
success, the teacher will listen when peers discuss what
they learned while completing the worksheet and evaluate
the completion of the scavenger hunt worksheets
individually.
The student will be able to
identify different leaves by color, shape and size.
The teacher can document the
students success through completing this objective based
on the pervious nights homework assignment that the
students had to described the leaf they chose to bring
into class. In addition the teacher may document how the
students did as a class during the grouping of their
leaves (color, size, shape categories on white board).
B. Concerns or questions you have
about teaching this lesson?
The concerns I
may have about teaching this lesson is that going onto
the website and searching through the material might
cause the students to need more time to complete the
worksheet in class.
