PELC V – 1 1. ENERGY

Introduction:

The speed of light changes when it travels into different materials. The materials may cause the light beam to change direction of travel or to refract. Light travels slower in water than in air and slower still in glass because water has more matter than air and glass is denser or more matter than water.

I. Objective:Infer that light is needed to see objects.

II. Subject MatterTOPIC: Light is needed to See Objects

A. Materials – old cartolina paper or cardboard, paper clip or stapler, pair of scissors flashlight, candle, cardboard, cellophane, clear glass

B. References – Explore and Discover 3, p. 208212 PELC V. 1. Growing with Science and Science Health TM pp. 134-142.

C. Science Concepts:Light rays travel in a straight line. You see an object because there is light

which the object returns or reflects to your eyes.D. Skills – observing, inferring, describing, comparing, experimenting E. Values – Environmental awareness and concern.F. New Words: refract

Introduction

We heard sounds all around. Sound is produced when things move back and forth or vibrate. Some sounds vibrates faster so we hear a very loud sound, and when object does not vibrate so much we heard a soft sound.

I. Objectives Relate the sound made to the force applied and the characteristic of the vibrating object.

II. Subject Matter: Sound made to the Force Applied and the Characteristics of the Vibrating object.

A. Materials : guitar , toy instrument, hummer , nail , radio B. References: - Science and Health pp.181-182

Grooving with Science and Health pp. 167 -171 Any science book s PELC V. 2.2-3

C. Concept: - Sound made to the force applied. When an object vibrates faster, the sound is louder and when the object vibrates slower, we hear soft sound. If using lesser force, it produce soft sound and if more force applied, it produced louder sound.

D.Values: Carefulness E. Skills : observing , Comparing , Classifying , Describing F. Prerequisites: Force , vibrate III. Learning Activities:

PELC V – 3 ENERGY

Introduction

Force is needed to make something move. A force is a push or a pull that starts, stops the motion or changes the direction of a moving object. Force comes from different sources like gravity, wind, running water, electricity or muscles. Forces can be balanced on unbalanced.

II. Subject MatterTOPIC: Force and Motion

A. Materials – toy car, marbles, activity card, chartB. References –PELC V.3. Grade 3, Explore and Discover 3, (2004), pp. 228-231, Growing

with Science and Science and Health TM pp. 148-152.C. Science Concepts:

Force makes objects move and causes change in motion.The motion of an object is determined by forces acting on it.

D. Skills – observing, hypothesizing, formulating generalization E. Values – Application of force to produce motion. F. New Words: force, motion, inertia, accelerationIII. Learning Activities

Activity 1 Get These: toy car, marbles Do These:

1. Put the toy car and marbles on the ground.Make sure they are not moving.

2. Observe the toy car and marbles.Did they move? Why?

3. Push the toy car and the marble.Did they move? Why?

4. Stop the toy car and marble.Did they stop? Why?

3. Lesson Proper (Developmental Activities)a. Pre-activity bringing out materials for the activity setting standards for group activity

b. Activity Proper (using activity cards/chart) Let the class raise the problem. Have them formulate hypothesis. Follow up Activity 1. Do These:

1. Get a partner and ask him to push the back part of the toy car with the same force as you do.Did the toy car move? Why?


31


2. Tell him to apply more force in pushing the toy car.Did the toy car move? Why?

3. Hold the toy car on the palm of your hand.What makes it stay on your hand?Is there a force pulling it downward?

4. Post ActivityWhat did you discover?Let the class discuss their findings.Guide them in formulating their generalization.(An object remains at rest unless a force is applied to it)

5. Generalization Force makes objects move. The motion of an object is determined by forces

acting on it.6. Application

Have the pupils cite examples that support the generalization.Example: The book on the table remains at rest, when pushed, (force) it moves (motion).

Introduction

A force is a push or a pull. It can make non-living things move. However, to make an object moves a bigger force must be applied to overcome the force acting on it. If the force applied to an object is lesser than the force exerted by the object, the object will not move. The force acting on the object and the force applied must be unbalanced, to make the object move.

I. Objectives Demonstrate how force makes object move. II. Subject Matter How Force Makes Objects Move A. Materials: Toy cart, marbles B. References: Cyber Science 3, p. 266
