- COURSE DESCRIPTION:
Learners can decide whether materials are safe and useful by investigating about some of their properties. They can infer that new materials may form when there are changes in properties due to certain conditions.
Learners have developed healthful and hygienic practices related to the reproductive system after describing changes that accompany puberty. They can compare different modes of reproduction among plant and animal groups and conduct an investigation on pollination. They have become aware of the importance of estuaries and intertidal zones and help in their preservation.
Learners can describe the movement of objects in terms of distance and time travelled. Learners recognize that different materials react differently with heat, light, and sound. They can relate these abilities of materials to their specific uses. Learners can describe the changes that earth materials undergo. They can make emergency plans with their families in preparation for typhoons. They can observe patterns in the natural events by observing the appearance of the Moon.
- OBJECTIVES:
At the end of the quarter, the learners will be able to:
- construct observations in the environment based on what is perceive by the pupil’s senses;
- understand the nature of an observation (realistic) and its importance to the different scientific processes;
- differentiate quantitative and qualitative obserations;
- define a hypothesis from a given observation;
- differentiate observation from inferencing;
- explain the parts and steps in designing an experiment;
- differentiate the nonstandard units measures used in the Philippines;
- explain the safety rules to be observed before, during and after an experiment;
- use the properties of materials whether they are useful or harmful;
- investigate changes that happen in materials under the lack of oxygen and application of heat condition;
- recognize the importance of recycle, reduce, reuse, recover and repair in waste management; and
- design a product out of local, recyclable solid and or liquid materials in making useful products.
