Star If the Sun is a medium sized star, why does it appear larger in the sky? The sun looks bigger because it’s closer to us than other stars True or False: The sun is one of many stars in our galaxy False: It’s the only star in our galaxy Name the 6 layers of the sun Core Radiative Convection Photosphere Chromosphere Corona Does the sun move across the sky? No, the sun only seems to move across the sky due to the rotation of the earth. We are moving, not the sun! What is the definition of gravity? An invisible forces that pulls between objects What are two things that effect how strong gravity is? Mass and how far away the objects are from each other If you hold a rock on the moon, and let go of it, what happens? It will fall to the ground True or False? Air resistance can effect how quickly gravity pulls something to the ground True True or False? There is zero gravity on the Moon. False How long does it take the earth to rotate on its on axis once? 1 day or 24 hours How long does it take the earth to orbit the sun? 365 days or one year. What is the shape of the Earth? Sphere What is larger? The moon or the Earth? Earth What causes night and day? The Earth rotating (spinning) on its’ axis. Which drawing shows how the Sun and Earth move? B. Which diagram compares the distances among the Sun, Earth and Moon? D We know the Earth is a sphere. Why does it appear flat from our perspective here at school? It appears flat because we are on only a very small part of the earth. Pretend the Earth is glass and you can look straight through it. Which way would you look, in a straight line, to see people in far-off countries such as China or India? D Why do we see different constellations during different parts of the year? The Earth orbits the Sun so we are in different locations of our solar system throughout the year causing us to see different constellations
