Learning Activities for Outcome 1

Let us take a look at some measuring instruments, what does each one measure, what is the range of measurement?

Roulette for measuring length of wood

Ruler to measure length on paper

Measuring tape used in dressmaking

All the above instruments measure lengths and they have a range to measure m to cm.

05:47


Scale measuring mass of commercial items

Digital scale measuring mass in lab and pharmacy

Weighing scale for bigger objects.

The above instruments measure mass but they measure different ranges: 1. kg to g 2. g to 1/100 g 3. kg to g

05:47


Common liquid thermometer

Infra-redDigital thermometer

Remote infra-red digital thermometer

Digital lab thermometer

All the above instruments measure temperatures of different ranges: 1. ºC 2,3 and 4. up to 0.01ºC

Can you name other instruments, say what they measure and the range of its precision?

05:47


Accuracy of an instrument – its capacity to measure as close as possible to the true value.

Range of measurement – the highest and lowest values that the instrument measures.

Precision of measurement – the closeness of the values of measurement.

Sensitivity of measurement – the ability to detect small changes in the values of measurement.

Compare the 4 different thermometers that we have seen.

TASK 1: Measuring temperature of liquidsMaterials: thermometer, beaker, warm water and cold water,kettle.

Method:1.Fill the beaker with 100 ml of tap water.2.Measure the temperature and record it in your table.3.Repeat steps 1 and 2 two more times.4.Fill the beaker with 100 ml of warm water provided by the teacher.5.Measure the temperature and record in your table.6.Repeat steps 4 and 5 two more times.

05:47


Analysis of results:1.How close are your measurements of the temperature of the cold water? of the warm water?2.What is the range of measurement of your thermometer? How do you know?3. Is your thermometer sensitive? Why?

Review

• Swap books with the person next to you and look over their work. Write a WWW and EBI statement.

• Tell the person next to you three things you have learnt this lesson and the skills you used in this lesson.

• Did you successfully complete tasks at your target level?• If not, what do you need to do next in order to meet your

target level? Record this in your diary to be done as part of your extended learning at home.

• Is there any part of the lesson you think you need to go over again next lesson?

• How will you remember what you have learned today for your exam?
