Exploring various modes of measurements and standard units for them.
Objectives
- Develops the ability to obtain accurate measurements and communicate those measurements is a key requirement for progress.
- Standardized measuring units ensure uniformity in measurements.
Estimated Time
1 hour
Prerequisites/Instructions, prior preparations, if any
- The students should have been introduced to the concept of formal measurements by conducting an activity on using standard measuring instruments.
- They should understand the importance of standard measurements and distinction between standard and non-standard units of measurements.
- They should be well versed with standard units and sub units.
- They should know unit conversions.
- They should have the skill of measuring and recording accurately.
- They should be aware that comparisons can be made only between similar measuring units.
Materials/ Resources needed
Non digital:
- Weighing pan with measures of 1 kg, 500gm, 250gm and 100gm and 50gm.
- Digital scale
- Postal scale.
- Measuring cans of 1 litre, 500ml, 250 ml, 100ml,
- Measuring tape, Ruler.
- Watch or stop clock.
- Paper and pen.
Process (How to do the activity)
- The idea here is to include several measuring units for practice.
- Initially instruct the students regarding the activity and its purpose.
- Group students into 3 in each.
- The teacher shall make packets of things as treasure and hide them in the school premises.
- The students shall pick chits containing clues to hunt and find the packets.
- 30 minutes is given to search.
- The students search packets and come back to classroom.
- The packets may contain cloth, ribbons, ropes, water, fruits, ingredients , vegetable , books , juice, stamps,envelops or any such measurable items.
- The students have to quickly decide which measuring mode they are going to use, measure and record their findings.
- They also have to measure the distance at which they found each and record the time taken to search.
- Developmental Questions
- What treasures did they find ?
- At what distance did they find ?
- How much time did they take to find ?
- What measuring instruments did they use ?, why ?
- How will they tabulate their results ?
- Can you list the purpose of each ?
- Evaluation
- What are standard the units of length ?
- What are the standard units of weight ?
- How are liquids measured ?
