III. PROCEDURES

1. Reviewing previous lesson or presenting the new lesson

What are the four types of climate in the Philippines?

What are the different kinds of instruments used by astronomers to the information about stars?

How can stars, as observed at night be described?

What are the kinds of stars according to their size?        

2. Establishing a purpose for the lesson

Stars are a source of inspiration to many people, why?

Have the class sing: When You Wish Upon a Star

You have sometimes watched stars at night. What are some of observations?

What do you know about the size of the stars? Can you imagine the size of the stars?

Which star appears brightest to us? Why?

A. Preparation

3. Presenting examples/instances of the new lesson

Do stars move? What do you need in order to make your observations?

b.         Group the children into four and make their own improvised telescope following the instructions in Activity 7.1, "A Tube to Observe the Sky".

c.         The groups discuss the answers to the questions in the activity

Observe the stars in a dear night sky. Do they appear to twinkle?

Do activity 7.2 p. 245 Stars and Our Sun

What conclusion can you draw about stars?

        The sun is a million larger than the earth. Although, this may sound huge, the sun is really only an average star. It is a medium-sized star.

Illustration shows a round thing.

A round thing is measured in terms of its diameter. Diameter is a straight line that cuts a circle passing through the center point.

Do Activity 7.3 related to the brightness of stars. This activity was done four days ago before class discussion,

Activity 7.4 is performed by the last two groups.

B. Setting of Standards

4. Discussing new concepts and practicing new skill #1

What are the different kinds of telescope?

b.         Why is it necessary to study heavenly bodies?

You know that the sun is a star. What is the sun's color? What different o of the stars have you seen? Have you seen a red star? A blue star? A white star?

Do activity 1 on page 248 of Science and Health, using different coins, a ruler and a piece of string to compare the diameter and the circumference of a circle.

Discuss with the groups their observations/experiences in performing the activities.

C.  Explanation

5. Discussing new concepts and practicing new skill #2

.         What is the use of a telescope?

d.         Where are the different kinds of instruments housed?

Are all the stars of the same size? Have you noticed that some stars smaller, bigger than others?

c.          Where do stars get their light? Do all the stars show the same brightness?

        Some stars are so large, yet they cannot be seen by the naked eye because they are too far away. In size, our sun is an average star. It is not too large or too small. The diameter gives us an idea of the size of a round object.

Analyze through the charts, which stars appear to be the brightest and the dimmest.

6. Developing mastery (Leads to Formative Assessment)

D. Supervision by the Teacher

7. Finding practical applications of concepts and skills in daily living

Discuss materials and procedures for making a star viewer, p. 242. IV. Evaluation

In terms of the weather condition, what does a starry night mean?

How does the sun compare in size with other stars?

Compare Aldebaran with Epsilon Aurigae in size.

Compare the sun's absolute brightness with the other stars. Which stars are brighter than the sun? fainter than the sun?

8. Making generalizations and abstractions about the lesson

What instrument and procedures are used by astronomers to gather information about stars?

What characteristics of the stars can be observed at night?

What are the kinds of stars as to size?

What is the brightest of the stars that we see at night?

9. Evaluating learning

Choose the letter of the correct answer.

1.         How is the composition of stars determined?

a.         by using a telescope

b.         by using a spectroscope

c.         by using a parallax

d.         both a and b

1-3. Besides yellow, identify other colors of stars.

4.         Describe how stars may differ as to size.

5.         Describe how stars differ as to brightness

1.         Giant stars are old stars.

2.         Betelgeuse is a red giant.

3.         A white dwarf is a newly born star.

4.         The sun is a yellow dwarf.

5.         A black hole is a dead star.

Choose the letter of the correct answer.

1.         The Greek astronomer who set up a system for measuring the magnitude of stars.

a.         Hipparchus

b.         Hippocrates

c.         Ptolemy

d.         Galileo

Checking and Recording

10. Additional activities for application or remediation

Collect pictures of telescopes, spectroscopes and space probes. Label each picture and write at least one function of each instrument.

1.          Using your improvised instruments viewer, observe a group of stars.

2.          Draw what you observe on a piece of bond paper and so on.

3.         In what ways do stars differ?

4.         Why do we see stars only during the night?

Do a library research on the evolution or life stage of a star.

Differentiate between apparent and absolute magnitude of a star.
