SHS1 Physics · Semester 1 Week 2: Introduction to Physics

Lesson notes

Learning Objectives

Indicator: 1.1.1.LI.1 - Identify the basic units in physics.

By the end of the lesson, learners can:

State the seven base (fundamental) quantities in physics and their corresponding SI units.
Write the standard symbols for the base quantities (mass, length, time, etc.) and their units (kilogram, metre, second, etc.).
Recognise that all other physical quantities, called derived quantities, are built from combinations of the base quantities.
Identify the basic units that make up common derived quantities such as area, volume, speed and density.
Recall the approved SI base unit for a given instrument or measuring device displayed in class.

Exemplars (from the NaCCA curriculum)

Talk for learning: Let learners come out with some derived units and their quantities by brainstorming. i. e. guide them to identify the basic units and their quantities.
Ensure that the teaching materials, examples, and illustrations reflect diverse perspectives.
Assessment (1.1.1.AS.1). The document marks these depth-of-knowledge levels for this indicator: Level 1 Recall.
