4. PROCEDURES
4.1 Introductory
Activity
A review will be made by asking these questions:
1. How to express the concentration of solutions in a quantitative
manner?
2. How to solve for the percent by mass? Percent by volume?
The students will be tasked to answer the problems in the activity sheet.
A. Solve for the unknown. Show all work and report answers with
units.
4.2 Activity
1. What is the percent by mass of 5.0 g of iron (II) sulfate dissolved in
75.0 g of water?
2. A solution is made by adding 25 mL of benzene to 80 mL of toluene.
What is the percent by volume of benzene?
3. A solution is formed by adding 35 g of ammonium nitrate to 250 g of
water. What is the percent by mass of ammonium nitrate?
4. An experiment requires a solution that is 80% methyl alcohol by
volume. What volume of methyl alcohol should be added to 200 mL of
water to make this solution?
4.3 Analysis
Which of the problem/s is/are hard for you to answer?
4.4 Abstraction
Checking of the answers to the problems in the activity sheet.
4.5 Application
Why is there a need to measure the concentration of solutions
accurately?
4.6 Assessment
The activity sheet will serve as an assessment for the students.
4.7 Assignment
Students will study in advance on how to compute for the exact ratio of
solute and solvent in a given solution.
4.8 Concluding
Activity
5. REMARKS
6. REFLECTIONS
Indicate below special cases including but not limited to continuation of lesson plan to
the following day in case of re-teaching or lack of time, transfer of lesson to the
following day, in cases of classes suspension, etc.
Reflect on your teaching and assess yourself as a teacher. Think about your student’s
progress this week. What works? What else needs to be done to help the students learn?
Identify what help your instructional supervisors can provide for you so when you meet
them, you can ask them relevant questions. Indicate below whichever is/are
appropriate.
A. No. of learners who
earned 80% in the
evaluation.
B. No. of learners who
require
additional
activities for remediation.
C. Did the remedial
lessons work? No. of
learners who have caught
up with the lesson.
D. No. learners who
continue
to
require
remediation.
E. Which of my learning
strategies worked well?
Why did these work?
F. What difficulties did I
encounter which my
principal or supervisor
can help me solve?
G. What innovation or
localized materials did I
use/discover which I wish
to share with other
teachers?
