Unit #0-01

Learning Outcome

At the end of this lesson, you will be able to:

• understand the basics of the SI system

• understand that when measuring something we need a quantity and a unit

Lesson

• watch the video, "Base Units - A Level Physics"

• 7 basic units of SI system are:

  • length (m)

  • mass (kg)

  • time (s)

  • electric current (A)

  • temperature (K), (not Celsius, but we could use it!)

  • amount of a substance (mol)

  • luminous intensity (cd)

• remember every measurement is made up of a quantity and a unit

  • ex. 7 m, 15 kg, 3 s, ...

• REMEMBER: it is always show as a number, 1 space and then the units

  • NEVER (except when we are showing something on the Micro:Bit!) use ^ to represent exponents, ALWAYS use unicode characters!

    • Ex: 4 cm²

      • I googled "unicode squared"

Activity

• from now on, whenever you refer to a measurement of any kind, you MUST include the units with 1 space
