The document outlines the Grade 4 science curriculum for the component "Living Things and Their Environment". It includes 18 key learning competencies that cover various topics: 1) The major organs of the human body and their functions. 2) How animals' body structures help them survive in different habitats. 3) Specialized structures that allow plants to survive on land and in water. 4) The life cycles of humans, animals, and plants and how the environment can affect them. 5) Beneficial and harmful interactions between living things and their environment. The overall goals are for students to understand how living things adapt to their environments, the interdependence between organisms and their habitats, and the

In Grade 4, the learners are introduced to the major organs of the human body.
They also learn about some parts that help plants and animals survive in places where they live.
Learners learn that humans, animals, and plants go through life cycles. Some inherited traits
may be affected by the environment at certain stages in their life cycles. Learners investigate that
animals and plants live in specific habitats. Learners learn that there are beneficial and harmful
interactions that occur among living things and their environment as they obtain their basic
needs.
The learners should be able to construct a prototype model of organism that has body parts
which can survive in a given environment
The learners demonstrate understanding of how the major internal organs such as the brain,
heart, lungs, liver, stomach, intestines, kidneys, bones, and muscles keep the body healthy

LIVING THINGS AND THEIR ENVIRONMENT
At the end of Grade 4, learners can investigate changes in some observable properties of
materials when mixed with other materials or when force is applied on them. They can identify
materials that do not decay and use this knowledge to help minimize waste at home, school, and
in the community.
Learners can describe the functions of the different internal parts of the body in order to practice
ways to maintain good health. They can classify plants and animals according to where they live
and observe interactions among living things and their environment. They can infer that plants
and animals have traits that help them survive in their environment.
Learners can investigate the effects of push or pull on the size, shape, and movement of an
object.
Learners can investigate which type of soil is best for certain plants and infer the importance of
water in daily activities. They learned about what makes up weather and apply their knowledge of
weather conditions in making decisions for the day. They can infer the importance of the Sun to
life on Earth.
