PROCEDURE A. Preliminary Activities Greet the students and have someone to lead the prayer. Afterwards let the students pick up pieces of paper under their chairs and let them sit properly. Checking of attendance. A1. Review of the previous lesson (The teacher will call student’/s to recap the past lesson.) B. Motivation The teacher will present a video (“Eureka” the story of Archimedes and the Golden Crown) and allow the students to give their own interpretation on the video they watched on the questions that the teacher will be asking. 1. What is your observation on the the video? 2. What the video tells about? 3. What comes into into your mind when you watch the video? C. Presentation / Discussion The teacher will discuss concept of fluids, density, pressure and buoyancy with the student and provide examples. D. Activity The students will be grouped into three and they will be given a problem relating to density. Each group was given a time of 15 minutes and 5 minutes to present their answers with solution in the class.

Group 1: A student has a sample of aluminum that has a mass of 27 g and a volume of 10 cm3. What is the density of aluminum? Group 2: A loaf of bread has a mass of 500 g and volume of 2500 cm3. What is the density of the bread? Group 3: A block of wood has a mass of 6.0 g and a volume of 12.0 cm3. What is the density of the block of wood?

E. Analysis The teacher will present a picture, compare and ask if which is denser. F. Abstraction The teacher will give or ask students to give the summary of the discussion. 1. It is the degree of consistency measured by the quantity of mass per unit volume? 2. How do we measure density? 3. How is the density of a weight or liquid measured? G. Application The students will be grouped into four and let the students think and write a problem relating to density. Each group was given a time of 10 minutes and 5 minutes to present their answers with solution in the class. IV.

EVALUATION 1. The measure of the gravitational force of an object is called? 2. The amount of matter in an object is called? 3. T/F? Your weight is different on the moon. 4. T/F? Your mass is different on the moon. 5. T/F? Volume is the amount of space an object takes up.

V.

ASSIGNMENT 1. What is the difference between mass and weight? 2. Make an research about buoyant force.

Key to corrections Activity: 1. A student has a sample of aluminum that has a mass of 27 g and a volume of 10 cm3. What is the density of aluminum? Density = mass/volume Density = 27 g / 10 cm3 Density = 2.7 g/cm3 2. A loaf of bread has a mass of 500 g and volume of 2500 cm3. What is the density of the bread? Density = mass/volume Density = 500g / 2500cm3 Density = 0.2 g/cm3 3. A block of wood has a mass of 6.0 g and a volume of 12.0 cm3. What is the density of the block of wood? Density = mass/volume Density = 6.0g / 12.0cm3 Density = 0.5 g/cm3 Evaluation: 1. Weight 2. Mass 3. True 4. False 5. True
