LESSON: Universe and Solar System
TIME FRAME: June 30-July 4, 2025
I. OBJECTIVES
At the end of the lesson the students will be able to:
A. know about the formation of the universe.
B. differentiate between the members of the Solar System.
C. understand the motions of the Earth and its effects.
D. learn about the different spheres of the Earth and their interaction with each other.
II. SUBJECT MATTER
Universe and Solar System
III. MATERIALS
Chalk, Board, Ppt, Laptop
IV. PROCEDURE
A. Preparation
1. Prayer
2. Greetings
3. Checking of attendance
4. Proper arrangement of chairs and class order.
A. Motivation
Let the students perform the game (Dancing pair) by answering the questions:
What is our solar system?
Why is it important for us to learn about our solar system?
Have you ever looked at the stars and wondered what lies beyond?
B. Lesson Proper
The term ‘Universe’ is derived from the Old Latin word ‘Univorsum’, in which ‘uni’ refers to
“one” and ‘Versum’ refers to “something that rolls or rotates.” This Latin term was then adapted
in French as ‘Univers’ and later in English was adopted as ‘Universe.” All the planets, galaxies,
stars, every minute particle that has its existence constitute the Universe.
A Solar System can be defined as a system comprising of a star and all the materials that
surround the star. The most familiar is the Solar System that is associated with our planet. Our
Solar System consists of the Sun as the central star and eight planets that revolve around the
Sun. The Solar System not only comprises of Sun and planets but also some smaller objects
such as asteroids, comets, and meteoroids.
Show them a video on the origin of the solar system.
The Origin of the Solar System
⚫ Nebular Theory- the sun and its planets supposedly condensed out of swirling bodies
of cold, dark, interstellar clouds of dust.
⚫ Fission Theory- tells that our sun burst one day and all planets can form it.
⚫ Capture Theory-suggest that our planet and moons were wandering around the space
and the planets were captured by the gravity of our sun and the moons were captured
by the planet.
⚫ Accretion Theory- tells that small chunks of the material separately formed
themselves into our Earth and the moon
⚫ Planetary Collision Theory - says that our world is said to have collided with a small
planet.
⚫ Stellar Collision Theory- suggest that our planets, moons and the sun all spun off
from a collision between stars, as with most of the other theories
⚫ Gas Cloud Theory- tells that gas clouds were captured by our sun, which then
mystery ally formed themselves at a distance into planets and moons
D. Activity
Directions: make a graphic organizer that shows the relation of different hypotheses on the origin
of solar system.
