ENGAGE: To have an Overview of the lesson please read the topic Comets, Asteroids, and Meteors on LM p. 153. Picture Analysis Directions: Identify the pictures and describe each D. EXPLORE CHARACTERISTICS Appears as a streak in the sky Frozen ball of dust Is visible in our sky Made up of rock Orbits the Sun Orbits between Jupiter and Mars Often called “Shooting Stars” Usually burns up the Earth’s atmosphere E. EXPLORE F. EXPLAIN: 1. Has Earth ever been hit by a comet or an asteroid? 2. If yes, how have such impacts affected Earth? 3. How often does a comet or an asteroid hit Earth? G. ELABORATE Write 5 superstitious beliefs that coincide with the appearance of meteorites and comets. H. ELABORATE: I. EVALUATE: A near-Earth object (NEO) is any small Solar System body whose orbit brings it into proximity with Earth. They include about thirteen thousand near-Earth asteroids (NEAs), more than one hundred near-Earth comets (NECs), and a number of solar-orbiting spacecraft and meteoroids, large enough to be tracked in space before striking the Earth. It is now widely accepted that collisions in the past have had a significant role in shaping the geological and biological history of the planet. NEOs have become of increased interest since the 1980s because of increased awareness of the potential danger some of the asteroids or comets pose to Earth. Directions: Write the letter of the correct answer. 1. An instrument used by astronomer to look for heavenly bodies in the sky. a. telescope b. kaleidoscope c. gyroscope d. microscope Ans. A 2. A shooting star is more accurately termed as a. meteors b. comets c. meteorites d. moons Ans. C 3. What NEO stands for? . near Earth office b. near Earth optics c. near Earth orbit d. near Earth objects Ans. D 4. An object at appears like a streak in the sky. a. comets b. satellite b. moons d. meteor Ans. A 5. It is an object in the sky that usually burns up as it enters the earth Atmosphere. a. meteorites b. satellite c. moons d. planets Ans. A EXTEND J. Bring the following materials for tomorrow’s activity. 1 rectangular container (aluminum tray or plastic) 1 pebble (1-4 cm in diameter) colored flour/colored starch pencil V. REMARKS VI.

ELICIT: Compare the characteristics of these Near Earth Objects (NEO's), comets, meteors, and asteroids. B. ENGAGE See table 1. Comparison of some characteristics of Comets and Asteroids then answer the question after it. C. ENGAGE: Watch the video clip entitled: Discovery Channel-Large Asteroid Impact Simulation D. EXPLORE: 1. Fill the rectangular tray with colored flour about 3-4 centimeters deep. 2. Place the tray on top of a table (or armrest of a chair). 3. Throw a pebble to hit the flour in the tray. Do this about four times, hitting different parts of the flour in the tray. 4. In the space below, draw the shape of the “craters” made by the pebble on the colored flour as: a. viewed from the top. b. viewed from the side F. EXPLAIN : G. ELABORATE 1. What do you notice about the shape of your pebble’s crater and the shape of the impact crater shown in the photo? 2. What do you think happened to the plants and animals living in the area where the comet or asteroid crashed? Directions: Draw and interpret the impact of an asteroid as it hits the Earth surface. Use the rubrics for checking. CRITERIA The concept being conveyed is delivered clearly. RATING 5 4 3 2 1 The drawing is realistic in relation to concepts learned. 5 4 3 2 1 Cleanliness 5 4 3 2 1 5 4 3 2 1 Creativity. H. ELABORATE : I. EVALUATE : Impact craters resembles the shapes of the asteroid which is usually circular. The crater is relatively larger than the meteorites itself because of the intensity of the impact. The immediate surrounding during impact is pulverized by the intense heat and force created by the impact. Directions: Enumerate the possible effects of a giant meteorites smashing into the earth. 1. 4. 2. 5. 3.. J. EXTEND: Watch the movie “Deep Impact”, state some notable scenes about collision of an asteroid with the Earth. V. REMARKS VI. REFLECTION A. B. C. D. E. F. G.
