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.

I. Objectives

            At the end of the unit, the students will be able to:

1. Describe the components of a scientific investigation;
2. Distinguish mixtures from substances based on a set of properties;
3. Recognize that substances are classified into elements and compounds;
4. Investigate properties of unsaturated or saturated solutions;
5. Express concentrations of solutions quantitatively by preparing different concentrations of mixtures according to uses and availability of materials
