A Detailed Lesson Plan in Chemistry I. TOPIC: Metals and Non-Metals II. OBJECTIVE: At the end of 45 minutes discussion, the students will be able to: General Objective: classify elements as metals or non-metals based on their properties. know their commitment to their respective responsibilities given to them.

Procedure A. Learning Activities
Teacher’s Activity
Student’s Activity
“Let start our class with a prayer to be lead by...”
(One Student will lead the Prayer)
“Good Morning Class...”
“Good Morning Ma’am!”
“Please pick up the pieces of paper under your chair and arrange your chairs”
(Students pick up the pieces of paper)
“Please be seated”
(Students seat to their respective chairs) (No absent Ma’am)
“Ms. Beadle who is absent Today?” “Very Good!” “Were you able to do your assignment?” “Ok! Kindly pass it to the front” “How did you come up with the answer in your assignment?” “ from our last meetings discussion we were able to differentiate the elements and where they name at after” “In connection to that our objective for today’s lesson is Properties Metals
(Students listen attentively)
Nonmetals
Hard, dense, solid (except mercury)
Strong (can hold heavy loads without breaking)
Shiny and can be polished
Malleable ductile
(Yes Ma’am!) (Passing their assignments) (from the periodic table)
Dull, cannot be polished (except diamond)
Brittle
Not sonorous
Insulators (except graphite)
Have low melting points
Have densities
and
Sonorous (ringing sound can be heard when struck)
Can conduct heat and electricity.
Usually have high melting points
Have high densities
Some are gases, liquids, or solids; less dense and softer (except diamond)
low
(Students listen attentively)
(Students form a group and follow the instruction of the teacher and perform the activity)
