1. Lesson: Measurement

2. Science Differentiation in action Important measurements include: Length -Distance between two points Area -Amount of surface Volume -Amount of space an object takes up Mass -Amount of matter in an object

3. Science Differentiation in action How can we measure length? Ruler or metre stick Opisometer Trundle wheel Callipers Vernier callipers Length is measured in __________ metres (m).

4. Science Differentiation in action How can we measure area? Regular shape Use a ruler to measure the length of each side. Multiply one side by the other to find the area. Irregular shape Use graph paper. Draw around the object and then count the squares inside the lines. Area is measured in__________________ metres squared (m 2 ). l b Area = l x b You must know the area of each square on the graph paper.

5. Science Differentiation in action How can we measure volume? Regular object Irregular object or liquid Use a measuring cylinder. How? Volume is measured in ________________ Use a ruler to measure length, breath and height. Multiply length by breath by height. metres cubed (m 3 ). lb h (v = l x b x h)

6. Science Differentiation in action How can we measure mass? Place the object on an electronic balance. Mass is measured in ____________ Kilograms (kg).

7. Science Differentiation in action Remember! Measurement Units Length -Distance between two points Area -Amount of surface Volume - Amount of space an object takes up Mass -Amount of matter in an object m m2m2 m3m3 kg

8. Science Differentiation in action 1. What do we use to find the volume of an irregular solid? Review Questions HINT 2. What do we use to find the mass of an object? HINT

9. Science Differentiation in action What would it be like to live in a world without measurement? Question to think about!
