A Detailed Lesson Plan in Science (First Year—Secondary)
At the end of the lesson, the students will be able to:
A. Describe the polarity of a water molecule and explain how that polarity affects the properties of water.
B. Explain why water climbs the inside of a thin glass capillary but not a thin plastic capillary.
C. Describe a system whereby the components of a water-based substance might be separated and discuss how this separation occurs.
D. Explain why oil and water don't mix.
E. Predict whether a substance, based on its hydrophilic and/or hydrophobic properties, will dissolve into water or oil.

A. Learning Activities
“Good Morning Class...”
“Let us pray first...”
(Checking of Attendance)
“Please pick up the pieces of paper
under your chair”
“Have you ever wondered what’s behind water?—not bodies of water, but the water itself, the liquid, Everything in this world are made by God with their special functions... Now let us discover what’s so special about water.
“Good Morning Sir!”
(One Student will lead the Prayer)
(Students raise their hand and say present as the teacher calls in their name)
(Students pick up the pieces of paper)
(Students perform the activity)
(Students listen attentively)
1. Predict what will happen if you add a few drops of a water-soluble dye solution to each of the above graduated cylinders containing water and oil. Will the dye mix with the water, the oil, or both?
2. Add a few drops of dye to each cylinder. Use a glass stirring rod to penetrate the interface between each layer, giving the dye access to both water and oil. How does the dye behave in each cylinder? Does it diffuse into the oil? Into the water?
V. Assignment“Why is liquid very important not just to humans but to all the living things in the world? –Write on 1 whole sheet of paper
