Motivation
Divide the students into small groups with a maximum of four students per group.
Distribute pictures of foreign scientists to the groups. Each picture is covered with
cut-out pieces of paper. Let the students remove the covering in each picture to
reveal the photograph of a foreign scientist. Ask the following questions to the
students.
Sample Questions:
1.
2.
3.
C.
Who is the person in the picture?
If the person in the picture is a foremost biologist, describe his contribution in
the field of Biology.
Name other foreign biologists and their contribution in the field of Biology.
Activity: Group Discussion
Let students form a small group of four members. Ask them to discuss on foreign
biologists and their contributions in the field of Biology. Divide the students into
small groups with a maximum of four students per group. Let the students in each
group discuss particular foreign scientists and their contributions in Biology. The
teacher will see to it that there is no duplication of scientist among the different
groups. The following is the list of foreign scientists with significant contributions in
Biology.

While the groups are discussing their designated foreign scientists, the teacher
posts questions on the walls inside the classroom. After the group discussion, the
teacher calls on representatives from each group to describe the designated
foreign scientists and their contributions in the field of Biology. The teacher calls

on other students to pick out and answer a posted question on the wall. If the
answer is correct, the student gives the question to the teacher. If the answer is
wrong, the student posts the question back on the wall.
Sample Questions:
Question 1. He is a British naturalist who worked on the theory of evolution and
natural selection.
Answer: Charles Darwin
Question 2: He discovered the bacteria that cause anthrax, tuberculosis and
cholera.
Answer: Robert Koch
D.
Postlaboratory Discussion
Guess the Scientist
After the group discussions, the teacher calls on representatives from each group
to describe their group’s designated foreign scientist and his/her contribution in
Biology. The teacher calls on other students to pick out and answer a posted
question on the wall. If the answer is correct, the student gives the question to the
teacher. If the answer is wrong, the student posts the question back on the wall.
