Grade 6: Physics- Investigative science activity to understand the need of standard units of measurement.

             

Students were divided into groups. Each group was given a different object in their classroom ( e.g. blackboard , wall painting , window , cupboard etc)to measure. Each of the student in group measured the given object using body parts ( e.g. handspun , footsteps , arm length etc) and compared his/ her answer with others. They also calculated time required for each person to measure the object. Later the same objects were measured with the help of standard units ( meter scale ). So students were able to compare the two methods of measurement. This activity helped them to understand the need of having standard units of measurement.
