1. Standards for Measurement

2. Force The amount of push or pull on an object. Unit = Newton (N).
Use a spring scale.

3. Weight The amount of pull on an object based on gravity.
Unit = Newton (N) b/c gravity is a kind of force.
Use a spring scale

4. Mass The amount of matter an object is made of. Unit = gram (g).
Use a triple beam balance.

5. Which has a greater mass?
Which has a greater weight?

6. So what’s the difference between mass and weight?

7. Length The amount of distance an object is or travels.
Unit = meter (m).
Use a ruler.
To get AREA, multiply length X width (answer is units square)

8. Volume The amount of space an object takes up. Unit = liter (L).
Use a graduated cylinder or ruler.

9. To Get Volume Measure length, width and height then multiply.
Answer is units cubed.

10. Practice
Some boxes in a warehouse all have a length of 30 cm, a width of 30 cm and a height of 20 cm.
What is the volume of each box?

11. Temperature The amount of molecular motion in an object.
Molecular motion ↑, temperature ↑
Molecular motion ↓, temperature ↓
Unit = Celsius scale (°C)
Use a thermometer
