Procedure
Teacher’s activity
Student’s activity
a. Routinary activities Everybody please stand. ____ Can you lead the prayer?
Let’s bow our head and feel the presence of the Lord. Let us pray. Our Father, Who art in Heaven, hallowed be Thy name; Thy Kingdom come, Thy will Thy will be be done on earth as it is in Heaven. Give us this day our daily bread; and forgive us our trespasses as we forgive those who trespass against us; and lead us not into temptation, but deliver us from evil. Amen.
Good Morning. Class Monitor, is there any absent for today?
Good Morning Ma’am. Ma’am there’s no absent for today.
Okay! Nice to hear that. Before you take your (The students will pick up those pieces of paper) seat, please pick up those pieces of paper under your chair. You may take your seat.
Thank You Ma’am.
a. Review ___ Can you share with us about some information you remembered about the Planet Mercury?
Ma’am Mercury is one of the brightest planet and the nearest planet to the sun and appears in reddish color.
Okay, what about planet Venus?
Ma’am planet Venus is the third brightest object in the sky. It is the second planet to the sun and
has a color of silvery glow. Known as Twin Sister of planet Earth.
Why it is consider as twin sister of planet Earth?
Ma’am because it has the same mass and size as planet Earth has.
Okay, it seems you understand our previous topic.
b. Motivation
Let’s play 4 pics 1 word Divide the class into 3 groups. I have here set of pictures. Each item consist of 4 pictures under it is jumbled letters. Try to guess the word behind those pictures. Let’s start. On those pictures you guess, what words that comes to your mind after seeing those set of pictures? Anyone?
(The student will participate to the motivation)
Ma’am I noticed on the activity that those set of pictures are all about the planet “MARS”.
That’s it! D. Discussion In our Solar System it composed of eight planets. It is divided into two categories. Between the first four planets and last planets there is a belt that separated the Inner planets to outer planets and it is? Very good, The asteroid belt separated the Terrestrial planets to Jovian planets. Do you ever wonder how terrestrial planets evolved? What do you think? Yes because of impacts and the decay of their radioactive materials heated the the planets enough to reach their internal temperature, what do you call to the central inner part of a planet class? Okay, those silicate materials floated on the surface serves as the crust.
Ma’am its Asteroid belt.
Ma’am I think they formed because of impacts of other celestial objects.
Ma’am its core.
The terrestrial planet cooled at a rate that depended on their size, so as you can see the size of mercury shows that it cools faster than other planets. That’s why Mars has that size and it became inactive. Do you ever think why Mars have a reddish color? What do you think?
Very good. The Viking mission found out that not only Mars surface but its interior consist of iron compounds. NASA sent five spacecrafts, two Viking landers, Pathfinder, Spirit and Opportunity and all of them successfully landed on Mars. Pictures from Viking landers shows the rocky surface of Mars. Pathfinder images showed abundant evidence of ancient floods while Sojourner measured the chemical composition of rocks and soil. The Spirit and Opportunity rovers found strong evidence that water once covered the surface of Mars. Class do you think Mars had water before? They say that water once flowed on Martian channels the runoff and outflow channels. The run off channels are like river system but class this channel is not much like in river system of Earth, the channels in Mars is bigger than t he Earth that it can hold a huge amount of water. And this channels is one of the evidence that water exist on Mars before. But it happens that it is trapped as permanently frozen. Class where is the coldest place in Earth? All right, just like on Earth, Mars have polar regions and the coldest place. It contains polar caps and consit of water ice and carbon dioxide. If Mars have a polar regions that consist of water ice why it can’t it be a water? What do you think? Mars has a much thinner atmosphere than Earth as a result it is much cooler than Earth and didn’t receive too much sunlight. If our Earth atmosphere consist mostly of Nitrogen, in Mars it consist of carbon dioxide. That’s why the southern polar regions are consist of carbon dioxide.
Ma’am I compare planet Mars to a nail with rust. That rust gives a nail a reddish color. Just like in nail, maybe planet mars consist of rust.
Ma’am its not possible for Mars to have a flow of water before. Because of evidences that had been found. But it needs further study to prove that it is really true.
Ma’am in polar regions.
Ma’am maybe because if water really exist it will evaporate easily.
Half of the Mars Surface consist of Crater and said that ejected material appears to have flowed away from many craters. What can you say about this?
Ma’am I think it can be another evidence that water exist before on mars. That water was ejected away from the craters.
It is possible. Like in Earth, astronomers believed that there is a crustal motion activity happened on Mars. The most spectacular example of crustal motion is the Valles Marineris canyon system. Much of the crustal motion seems to have occurred as a consequence of the weight of the Tharsis bulge. Long ago, Mars experienced a period of plate tectonic activity. Do you still remember the greek mythology class? What is the name of the city where Gods and Goddesses lived? That city was came from the highest mountain in the Solar System that can be found on planet Mars and located on the Tharsis Region where the three shield volcanos (Arsia Mons, Pavonis Mons, Ascraeus Mons) can also be found.
Yes Ma’am. It’s about Gods and Goddesses. Ma’am its Olympus.
Still, planet Mars is on observing state but NASA have future missions about this planet. Can life be possible on this planet? Ma’am I think yes The Viking biology experiments showed that the Martian soil is chemically active, but probably does not harbor life. As I said it is still on observing state. Let’s wait for further announcement of NASA.
E. Generalization Okay class again why Planet mars called as a “Red Planet”? Ma’am because its surface is composed mainly of rust and because the iron within the dust reacted with oxygen, producing a red rust colour, while the sky appears red as storms carried the dust into the atmosphere. Very good. But why it is cooler than the Earth?
Ma’am because its atmosphere is much thinner than the Earth and it is farther than the Sun.
Okay very good. It seems you fully understand our topic for today. Let’s have some activity.
