THE SOLAR SYSTEM  Lesson objectives By the end of this lesson students should be able to: 1. Identify and describe the major components of the solar system. 2. Identify and classify planets according to their composition and size. 3. Compare inner and outer planets. LET’S REVIEW THE SOLAR SYSTEM! https://www.youtube.com/watch?v=PCxjuDePdCI Guess the planet… I am the King of Roman Gods. Who am I? I am the second largest planet. Who am I? I am the Greek God of Sky. Who am I? I am the red planet. Who am I? I take 17 hours to rotate. Who am I? I am the veiled planet. Who am I? I am the red planet. Who am I?  Fill in the blanks quiz ▪ What are the two groups of planets? __________ and __________. ▪ Which group of planets are closest to the sun? _________ ▪ Which group of planets are furthest from the sun? __________ ▪ Three differences between __________ and _________ are: ____________________________ ____________________________ ____________________________  THE ART OF COMPARISON When you compare two or more things you describe the similarities and differences between or among them. COMPARATIVE WORDS bigger, smaller, colder, hotter, closer, farther, but, while, however, on the other hand For example : 1)The inner planets are smaller than the outer planets. 2) The circumference of Mercury is 15,300 km while the circumference of Jupiter is 450,000 km. COMPARISON BETWEEN PLANETS The planets in the Solar System are compared in terms of: Composition Size Revolution Time Distance from the Sun and Temperature 1. COMPOSITION Inner planets are rocky (terrestrial) –composed of rocks such granite and basalt. –have a hard surface –may have valleys or volcanoes on the surface On the other hand, the outer planets are Jovian –made up mostly of gas –For example, Neptune is composed mainly of methane which is the reason for its blue colour. 2. SIZE Outer planets are significantly larger than the inner planets. Mercury is the smallest inner planet while Jupiter is the largest outer planet. Jupiter is 29 times larger than Mercury. – circumference- Mercury 15,300 km – circumference- Jupiter 450,000 km 3. Revolution time Inner planets have shorter orbits around the Sun and take shorter time to go around the sun. Outer planets have longer orbits and take a longer time to go around the sun. –For example- Neptune is the furthest planet from the sun and has a revolution time of 165 years while Mercury is the closest planet to the sun and takes 88 days to complete a revolution. 4. DISTANCE FROM THE SUN AND TEMPERATURE Outer planets The temperature is colder because they are further away from the sun. Inner planets The temperature is hotter because they are closer to the sun. -Neptune has temperatures of -2000℃ while Mercury has temperatures of 430℃ Exception-Although Venus is the second planet from the sun, it is the hottest planet with a temperature of over 4500℃.  CLASS ACTIVITY Answer the following question in your notebook. You will share your responses with the class. 1) What is a solar system? 2) Compare the inner and outer planets in terms of composition, size, revolution Time and distance from the Sun and temperature. This comparison must be as detailed as possible (Write complete sentences)  QUIZIZZ ACTIVITY https://quizizz.com/admin/quiz/5c546ce972 0fd9001b45f783/inner-and-outer-planets VIDEO ON INNER AND OUTER PLANETS
