Attendance will be taken once the teacher arrives inside the classroom. 2. Outputs must be submitted on or before the deadline, late outputs will only be entertained one week after the deadline with point deductions. 3. Respect Others: treat your classmates, teacher, and classroom materials with respect.  House Rules 4. The medium of instruction for EALS is English, you are expected to answer using the same. However, learners are allowed to answer and speak using whatever language you are comfortable. 5. Raise your hands – if you have questions, concerns, and meaningful contributions to the topic at hand, don’t hesitate to raise your hand then wait to be acknowledged. 6.

Where did they come from? Origin of the Universe Big Bang Theory As the currently accepted theory of the origin and evolution of the universe, the Big Bang Theory postulates that 13.8 billion years ago, the universe expanded from a tiny, dense and hot mass to its present size and much cooler state.  Known as the "Red Planet" because it appears faintly reddish/orange when viewed in the night sky. This reddish color comes from the abundance of iron minerals and dust.  Known as the "Red Planet" because it appears faintly reddish/orange when viewed in the night sky. This reddish color comes from the Mars abundance of iron minerals and dust.  Is often referred to as the "Evening Star" or the "Morning Star" due to its brightness in the sky. It's the third- brightest natural object in our sky, after the Sun and the Moon.  Is often referred to as the "Evening Star" or the "Morning Star" due to its brightness in the sky. It's the third- brightest natural object in our sky, after Venus the Sun and the Moon. Venus Earth Mars  Comparison VENUS EARTH MARS Mass (10^24 kg) 4.87 5.97 0.642 Diameter (km) 12,104 12,756 6,792 Density (kg/m3) 5,243 5,514 3,933 Gravity (m/s2) 8.9 9.8 3.7  Question: 1.

Lowest temperature?  Comparison VENUS EARTH MARS Distance from Sun 108.2 149.6 227.9 (10^6 km) Orbital Period (days) 224.7 365.2 687 Orbital Velocity 35 29.8 24.1 (km/s) Length of Day 2,802 24 24.7 (hours)  Question: 3. Explain the difference between the orbital period and length of days. What is the revolution and rotation? Venus, Earth, and Mars are part of the inner terrestrial or "rocky" planets. Their composition and densities are not too different from each other. Venus is considered to be the Earth's twin planet. It has a very similar size and mass with the Earth. Mars is about half the Earth's size. Orbital period and velocity are related to the planet's distance from the sun. Among the three planet, Venus is the nearest and Mars is the farthest from the Sun. Rotational speed of Earth and Mars are very similar. Rotational speed of Venus is extremely slow. Abundance of liquid water on Earth, hence the blue color. The Earth is a habitable planet.  Question: Is Earth habitable?  Question: What factors would make a planet habitable?  it is protected from harmful it has the right distance from solar radiation by its the sun magnetic field Right Magnetic Distance Field Right Atmosphere Ingredients for life has the right amount of it is kept warm by an ingredients for life, insulating atmosphere abundance of water  Do you believe that there is life outside the planet Earth? Lesson 2: Earth Sub-systems Review Give some qualities of Earth that made it sustain life. What is the importance of that quality in supporting life? Board work: Earth’s Sub-systems  Earth’s Sub-systems 1. Atmosphere 2. Lithosphere/Geosphere 3. Hydrosphere 4. Biosphere  1. Atmosphere The atmosphere is the thin gaseous layer that envelopes the lithosphere. The present atmosphere is composed of 78% nitrogen (N), 21% oxygen (O2), 0.9% argon, and trace amount of other gases. One of the most important processes by which the heat on the Earth's surface is redistributed is through atmospheric circulation.  2. Lithosphere/Geosphere The geosphere includes the rocks of the crust and mantle, the metallic liquid outer core, and the solid metallic inner core. The primary driving mechanism is the Earth's internal heat, such as that in mantle convection. Questions?  3. Hydrosphere About 70% of the Earth is covered with liquid water (hydrosphere) and much of it is in the form of ocean water. Only 3% of Earth's water is fresh: two-thirds are in the form of ice, and the remaining one-third is present in streams, lakes, and groundwater. Heat is absorbed and redistributed on the surface of the Earth through ocean circulation.  4. Biosphere The biosphere is the set of all life forms on Earth. It covers all ecosystems—from the soil to the rainforest, from mangroves to coral reefs, and from the plankton-rich ocean surface to the deep sea. For the majority of life on Earth, the base of the food chain comprises photosynthetic organisms Are clouds part of the hydrosphere or atmosphere? How does the Earth’s sub-systems interact?  Written Work # 1 (yellow paper) 1 2 How does the four subsystems interact when it comes to these scenarios?
