Grade 7 Science Q3 - Force, Motion, and Energy
-featured.png)
This Grade 7 course guides learners through forces and motion, graphing speed and velocity, and the fundamentals of thermal energy and heat transfer. Students practise measurements, free-body diagrams, and data interpretation, then investigate innovative, sustainable ways to convert heat to electricity. Interactive labs, real-life contexts, and research tasks build scientific thinking and communication skills relevant to the Philippine curriculum.

What you'll learn
- Identify forces acting between objects, measure their magnitude, and accurately construct free-body diagrams to represent balanced and unbalanced forces.
- Explain the difference between scalar and vector quantities, specifically differentiating distance from displacement in everyday motion scenarios relative to a reference point.
- Distinguish between speed and velocity using the concept of vectors, describe uniform velocity, and accurately represent and interpret motion using distance-time graphs.
- Differentiate between heat and temperature based on the kinetic energy of particles and explain how internal energy is transferred in various physical systems.
- Explain the processes of conduction and convection using the particle model and evaluate the advantageous and disadvantageous applications of all three heat transfer methods.
- Gather and present information from secondary sources describing innovative devices that efficiently transform heat energy into electrical energy, addressing global energy concerns.
