INTRODUCTION



The purpose is to engage my
students in the art process of
color.
Let the students know what is
going to be expected of them
during the lesson.
Positive reinforcement designed
to motivate the students.
Engage

1. I will use the overhead projector to display
several attribute blocks of the same size and shape,
but of a different color.

2. I will hold up a red and blue square and have the
students describe the two attribute blocks. The
teacher will say: Describe the attributes of these
objects.

3. The teacher will ask the students: What did you
use to determine the attributes? (My eyes) then the
teacher would ask : How are they alike? (shape and
size) Then I would ask?
6 CONTENT

EXPLORE:

1. The teacher will distribute objects
(blocks, toys, etc.) that vary in color
to the students.
2. The students will make a list of
attributes for each object.
3. The teacher will have the students
mix finger paints to make different
colors.


Explain


1. The teacher will show the students red,
blue, and yellow objects. Then the teacher
will ask: What color are these objects?
(red, blue, and yellow) I will then explain
that these three colors are called primary
colors.
2. I will then place red, blue, and yellow on
the Venn Diagram for the students to
observe.
EXPLAIN CONTINUED



3. The teacher will place the four plastic cups on the
overhead projector. The teacher will then pour
water colored with red food coloring into one cup.
Then the teacher will have the students predict what
will happen when the teacher pours yellow water
into the red water. The teacher will then write the
students predictions on the board. The teacher
then pours the yellow water into the cup with red
water and then asks the students what happened
when I added the yellow water?
(The students should respond The water turned
orange.)
Explain Cont 2


4. The teacher leaves the orange cup, and
then puts the blue cup and another yellow
cup on the overhead and asks the students
to predict what will happen when I mix
these two cups. (the students should
answer the color will be green)
The teacher then asked the students what
do you think will happen if I mix red and
blue together? They should answer (you
get purple) I then asked the students what
will happen if I mix red, blue and yellow
together in the same cup. (You get Black)
EXPLAIN CONT. 3

5. I THEN POINTED OUT THE THREE
PRIMARY COLORS AND THE THREE
SECONDARY COLORS.

6. I ASKED THE STUDENTS: What colors
make orange, green, and purple. Their
answer should be (red+yellow=orange,
blue+yellow=green, and blue+red=purple)
what color is formed in the middle? (black
or brown, depending upon the mix and the
paint.
7. Summary

Elaborate:

The way that the teacher intends on
wrapping up this lesson would be to
give the students the opportunity to
mix their own secondary colors using
primary colors.
The teacher gives each student their
own Venn Diagram worksheet to
experiment mixing colors in order to
get secondary colors.

8. Evaluation




1. The teacher will listen to the students to
determine whether they understand the proper
vocabulary such as primary, and secondary.
2. The teacher will observe the students to
determine if they can mix two primary colors to get
each secondary color.
3. The teacher will place two paint colors on paper
and have the students predict the color mix.
4. The teacher will give each student an informal
assessment worksheet to assess whether they can
answer the questions given on primary and
secondary colors.
