Explain and show diagrams on different types of
micrometer screw gauge used in everyday life.

Students will be asked to describe on the uses of
micrometer screw gauge with everyday situations.

Using the applet (obtained online resource), the students
will try to find out by themselves how the measurement 
are read with a given reading provided if the internet
connection is available at that time, IF NOT the teacher
will give the same particular reading of the instrument
with the use of the PowerPoint slide.

Teacher explains a detail step by step process on how to
read the reading of the micrometer screw gauge should
there be any problems encountered by the students.

The students will be given other examples to familiarize
on how to read the measurement on the micrometer screw
gauge.

After mastery, in groups, students were told to find any
particular objects to be measured inside the lab and jot
down their readings. The readings will be presented and
compared to the whole class.

As conclusion, the teachers will wrap the lesson by giving
exercise regarding the micrometer screw gauge.
