Organism as having a feedback mechanism, which are coordinated by the NS and
ES.
How these feedback mechanisms help the organisms maintaining homeostasis to
reproduce and survive.

Describe how the nervous system coordinates and regulates these feedback
mechanisms to maintain homeostasis.

D. Discussing new concepts
and practicing new skills #1
D. Explore
We will now have an activity. You will be given an activity sheet and then
I’ll be reading the instruction.
E. Discussing new concepts
and practicing new skills #2. The teacher will read the instruction.
1. Study the numbered diagrams/pictures of unsequenced events in the
menstrual cycle below.
2. Teacher will provide a table that will serve as a guide in arranging the
events based on its correct sequence. Cut and paste the correct picture based
on its corresponding stages/ events.
Follicular Stage
Ovulation
Luteal Stage
Menstruation
Pregnancy
F. Developing mastery
(Leads to Formative
Assessment)
EXPLAIN
The teacher will discuss further the feedback mechanism occur in menstrual cycle
based from the activity performed by the students. This will clarify student’s
misconception regarding the activity.
G. Finding practical
applications of concepts and
skills in daily living
H. Making generalizations and
abstractions about the
lesson
E. Elaborate
The learners will be introduced to the process called feedback mechanism. Show
how this mechanism work during menstrual cycle through a diagram.
1. What is a feedback mechanism?
2. In negative feedback, if the estrogen and progesterone are released by the
ovaries at a high level, what would happen to the amount of FSH and LH released
by the pituitary gland.
