Stage 3
Teaching/Learning Sequence:
EXPLORE
As part of initial activities, learners shall be given an overview of the cell as a highly organize structure,
understanding how discoveries on cellular structure and functions have led to useful technologies, what
they are expected to learn and how their learning shall be assessed. This also involves understanding or
making meanings out of the scientific knowledge obtained.
Learners shall:
1. undergo assessment on background knowledge of characteristics of life
2. be introduced the topic cell structures and functions and its subtopics
(Suggested Activity: The learners will trace development in technology and contributions of scientists that led to the
discovery of the cell. Research the following people: Robert Hooke, Hans and Zacharias Jannsen, Anton van
Leeuwenhoek, Matthias Schleiden, Theodor Schwann, Rudolf Virchow. List some of their contributions to science and dates
of these contributions. Refer to attached suggested activity CSF 1.)
3. be oriented on related and varied resources and materials to be used in understanding cell structures and functions (see
resources and equipment/materials needed)
4. be given time to formulate questions on cell structures and functions to initially find out what is/are interesting for them; be
given time to formulate other questions leading to the Essential Question focusing on the value of cell structures and
functions.
(Suggested Strategies: KWL, Focus Group Discussion, brainstorming, think-pair & square, dyads, round robin,
etc.)
5. generate as many tentative ideas (TI) related to the Essential Question (EQ) as possible to show what they already know
about cell structures and functions

6. 2010 Secondary Education Curriculum
Integrative Biology
(Suggested Strategies: Use brainstorming, Focus Group Discussion, graphic organizer, concept mapping, etc. At this
point, the teacher shall be careful not to reject learners’ opinion but shall encourage them to give their ideas without being
judged as right or wrong. Each tentative idea (TI) shall be written on the board.)
6. be grouped accordingly to choose some of the identified prior knowledge, alternative conceptions and tentative ideas (TI)
(Suggestion: Whatever each group of learners selected, the group shall be asked to challenge or explore the validity of
these prior knowledge, alternative conceptions or tentative ideas during the Firm Up Stage.)
7. be oriented that they need to show their understanding of cell structures and functions by developing products resulting
from this understanding.
8. be informed that these products resulting from understanding of cellular structures and functions shall be assessed based
on the following criteria: (a) Innovativeness/ creativity (b) marketability (c) replicability of the production processes(d) cost-
effectiveness (e) promotion of livelihood, food production and health.
(Suggestion: Brainstorming may be used to discuss how these criteria shall be used. Learners need to be clarified on the
details on how their product or performance shall be assessed. Such details of criteria may be revised based on
agreements reached.)
FIRM UP
Varied learning experiences shall be introduced to help learners disprove alternative conceptions,
examine/assess prior knowledge, and begin to discover the validity of tentative ideas(TI) related to the EQ;
make their understanding of cell structures and functions real; equip them with skills and knowledge; and
undergo differentiated instruction to address their unique strengths and needs. This involves acquiring
scientific knowledge which is about accessing information, i.e., what information is needed, where information
can be located and how information can be gathered focusing on cellular structures and functions

activities.)
(Suggested Strategies: making models, group discussion)
(Suggested Activity: Create an accurate, detailed 3-D model of either a plant or animal cell. Each organelle must have the
correct shape and be about the right size for the model (i.e., Ribosomes should not be larger than the nucleus). Models may
be edible or not. Refer to attached suggested CSF activity 4)
6. differentiate prokaryotic and eukaryotic cells
(Main Idea: There are many different cells that do many different things. But all of these cells fall into one of the two main
categories: prokaryotic cells and eukaryotic cells.

TRANSFER
There is no need to encourage learners to organize their learning experiences so that they can move
from teacher-guided and concrete activities to independent applications where they create or produce
new knowledge in science. This is to challenge learners to transfer their learning in new settings and use
this creatively to generate new ideas, view things differently and reengineer processes. Learners shall be
involved in designing, constructing, planning, producing new knowledge and/or inventing products
which can promote livelihood, food production and health.
Learners shall:
