K to 12 Curriculum Guide Science – version as of January 31, 2012 2
CONCEPTUAL FRAMEWORK
Science education aims to develop scientific literacy among students that will prepare them to be informed and participative citizens who are able to
make judgments and decisions regarding applications of scientific knowledge that may have social, health, or environmental impacts.
The science curriculum recognizes the place of science and technology in everyday human affairs. It integrates science and technology in the civic,
personal, social, economic, and the values and ethical aspects of life. The science curriculum promotes a strong link between science and technology,
including indigenous technology, keeping our country’s cultural uniqueness and peculiarities intact.
Whether or not students pursue careers that involve science and technology, the K to 12 science curriculum will provide students with a repertoire of
competencies important in the world of work and in a knowledge-based society. The K to 12 science curriculum envisions the development of scientifically,
technologically, and environmentally literate and productive members of society who manifest skills as a critical problem solvers, responsible stewards of
nature, innovative and creative citizens, informed decision makers, and effective communicators. This curriculum is designed around the three domains of
learning science: understanding and applying scientific knowledge in local setting as well as global, context whenever possible, performing scientific
processes and skills, and developing and demonstrating scientific attitudes and values. The acquisition of these domains is facilitated using the following
approaches: multi/interdisciplinary approach, science–technology society approach, contextual learning, problem/issue-based learning, and inquiry-based
approach. The approaches are based on sound educational pedagogy namely: constructivism, social cognition learning model, learning style theory, and
Gestalt psychology.
Science content and science processes are intertwined in the K to 12 curriculum. Without the content, learners will have difficulty utilizing science
process skills since these processes are best learned in context. Organizing the curriculum around situations and problems that challenge and arouse
students’ curiosity motivates them to learn and appreciate science as relevant and useful. Rather than relying solely on textbooks, varied hands-on, minds-on,
and hearts-on activities will be used to develop students’ interest and let them become active learners.
As a whole, the K to 12 science curriculum is learner-centered and inquiry-based, emphasizing the use of evidence in constructing explanations.
Concepts and skills in Life Sciences, Physics, Chemistry, and Earth Sciences are presented with increasing levels of complexity from one grade level to
another (spiral progression), thus paving the way to deeper understanding of a few concepts. These concepts and skills are integrated rather than discipline-
based, stressing the connections across science topics and other disciplines as well as applications of concepts and thinking skills to real life.

K TO 12 SCIENCE
The Conceptual Framework of Science Education
Developing and
Demonstrating Scientific
Attitudes and Values

K TO 12 SCIENCE
CORE LEARNING AREA STANDARD: (SCIENCE FOR THE ENTIRE K TO 12)
The learner demonstrates understanding of basic science concepts, applies science process skills, and exhibits scientific attitudes and values to
solve problems critically, innovate beneficial products, protect the environment and conserve resources, enhance the integrity and wellness of people,
and make informed and unbiased decisions about social issues that involve science and technology. This understanding will lead to learner’s
manifestation of respect for life and the environment, bearing in mind that Earth is our ONLY HOME.
KEY STAGE STANDARDS: (STANDARD FOR SCIENCE LEARNING AREA FOR K-3, 4-6, 7-10 AND 11-12)
K – 3 4 – 6 7 – 10 11-12
At the end of Grade 3, the
learners should have
acquired healthful habits
and developed curiosity
about self and their
environment using basic
process skills of observing,
communicating, comparing,
classifying, measuring,
inferring and predicting.
This curiosity will help
learners value science as
an important tool in helping
them continue to explore
their natural and physical
environment.
At the end of Grade 6, the learners
should have developed the essential
skills of scientific inquiry – designing
simple investigations, using
appropriate procedure, materials
and tools to gather evidence,
observing patterns, determining
relationships,drawing conclusions
based on evidence, and
communicating ideas in varied ways
to make meaning of the
observations and/or changes that
occur in the environment. The
content and skills learned will be
applied to maintain good health,
ensure the protection and
improvement of the environment,
and practice safety measures.
At the end of Grade 10, the learner
should have developed scientific,
technological and environmental literacy
so that they will not be isolated from the
society where they live, will not be
overwhelmed by change, and can make
rational choices on issues confronting
them. Having been exposed to scientific
investigations related to real-life, they
should recognize that the central feature
of an investigation is that if one variable is
changed (while controlling all others), the
effect of the change on another variable is
measured. The context of the
investigation can be problems at the local
or national level to allow them to
communicate with students in other parts
of the Philippines or even from other
countries using appropriate technology.
At the end of Grade 12, the learner
should have gained skills in
obtaining scientific and
technological information from
varied sources about global issues
that have impact on the country.
They should have acquired
attitudes that will allow them to
innovate and/or create products
useful to the community or country.
They should be able to process
information to get relevant data for
a problem at hand. In addition,
learners should have made plans
related to their interests and
expertise, considering the needs
of their community and the country
— to pursue either employment,
entrepreneurship, or higher
education.

K TO 12 SCIENCE
Grade/Level Grade Level Standards
K Concepts and skills in the kindergarten curriculum are taught thematically so that it is difficult to identify specific science ideas.
Grade 1
At the end of Grade 1, learners will use their senses to locate and describe the parts of their body and tell the shape, color, texture, taste,
and size of things around them. They will differentiate sounds produced by animals, vehicles cars, and musical instruments. They will
illustrate how things move. They will describe similarities and differences, given two things. They will use appropriate terms or vocabulary
to describe these features. They will collect, sort, count, draw, take things apart, or make something out of the things. They will practice
health habits (e.g., washing hands properly, choosing nutritious food) and help clean or pack away their toys. They will ask questions.
They will give simple answer/ descriptions to probing questions.
Grade 2
At the end of Grade 2, learners will use their senses to describe more than two objects and using more than two properties. They can
sort things in different ways and give a reason for doing so. They will describe the kind of weather or certain events in the home or school
and express how these are affecting them. They will tell why some things around them are important. They will decide if what they do is
safe or dangerous. They will give suggestions on how to prevent accidents at home (not playing with matches or sharp objects). They will
switch off light when not in use or conserve water when taking a bath or brushing teeth. They will help take care of pets or of plants. They
will tell short stories about what they do, what they have seen, or what they feel.
Grade 3
At the end of Grade 3, learners will describe the functions of the different parts of the body and things that make up their surroundings ---
rocks and soil, plants and animals, the Sun, Moon and stars. They will also learn that things may be solid, liquid or gas while others may
give off light, heat and sound. They will also observe changes in the conditions of their surroundings. These will lead learners to become
more curious about their surroundings, appreciate nature, and practice health and safety measures.
Grade 4
After investigating, learners will identify materials that do not decay and use this knowledge to help minimize waste at home, school, and
in the community. They will also investigate changes in the properties of materials when these are subjected to different conditions.
The learners will describe the internal parts of the body and their functions in order to practice ways to maintain good health. They will
classify plants and animals according to where they live and observe interactions among living things and their environment. They will infer
that plants and animals have traits that help them survive in their environment.

and structures using a microscope. They will understand that living things are organized into different levels: cells, tissues, organs, organ
systems, and organisms. These organisms comprise populations and communities which interact with nonliving things in ecosystems.
Grade 8
Learners will now recognize reproduction as a process of cell division resulting in growth of organisms. They will also deal deeper into the
process of digestion studied in the lower grades giving emphasis on proper nutrition for overall wellness. This will lead them to participate
in activities that will protect and conserve economically important species used for food.

Learners will also demonstrate ways to ensure safety and reduce damage during earthquakes, tsunamis, and volcanic eruptions.
Learners will investigate factors that affect the balance and stability of an object to enable them to practice appropriate positions and
movements to achieve efficiency and safety such as in sports and dancing. They will also analyze situations where energy is harnessed
for human use whereby heat is released affecting the physical and biological components of the environment.
