Science 7 aims to distinguish mixtures from substances through semi-guided investigations. They realize the importance of air testing when conducting investigations. After studying how organ systems work together in plants and animals in the lower grade levels, learners can use a microscope when observing very small organisms and structures. They recognize that living things are organized into different levels: Cells, tissues, organs, organ systems, and organisms. These organisms comprise populations and communities, which interact with non-living things in ecosystems.
Learners can describe the motion of objects in terms of distance and speed, and represent this in tables, graphs, charts, and equations. They can describe how various forms of energy travel through different mediums.
Learners describe what makes up the Philippines as a whole and the resources found in the archipelago. They can explain the occurrence of breezes, monsoons, and ITCZ, and how these weather systems affect people. They can explain why seasons change and demonstrate how eclipses occur.
At the end of the unit, the students will be able to:
- identify parts of the microscope and their functions;
- focus specimens using compound microscope;
- describe the different levels of biological organization from cell to biosphere;
- differentiate plant and animal cells according to presence or absence of certain organelles;
- explain why the cell is considered the basic structural and functional unit of all organism;
- differentiate asexual from sexual reproduction in terms of the number of individuals involve and similarities of offspring to parents;
- differentiate the biotic from abiotic components of an ecosystem;
- predict the effect of changes in abiotic factors on the ecosystem.
