Pre-Assessment Review For each question, read your initial answer and reflect on whether that answer is correct or incorrect. Check your answers to make sure you now have the correct information. Questions 1-3 1. Draw and label a diagram that shows the Sun, Earth, an object on the Earth (like a tree or pole) and the shadow that object would cast. Shadow should be pointing the opposite direction of the sun 2. What causes shadows to change length and position during the day? As the sun appears to move higher and across the sky, the shadow changes. The shadow will always point the opposite direction of the sun; the higher the sun is, the shorter the shadow will be. 3. At what time of day should a shadow be the shortest? The longest? Shortest at local noon; longest near sunrise and sunset. Questions 4-6 4. What direction do shadows point in the morning? In the evening? Morning shadows point west, evening shadows point east 5. What causes day and night to occur on Earth? Day and night are caused by the Earth’s rotation 6. What do you think is the reason for the Earth being divided into Time Zones? Times zones create common times in geographic areas to make things like travel and TV programming easier; they were originally created by the railroad companies. Questions 7-9 7. Why do you think we have longer daylight hours in the summer than we do in the winter? Summer hours are longer because we are tilted towards the Sun and stay out of the “shadow” for a longer period of time 8. Why are our temperatures warmer in the summer than in the winter? It is warmer in the summer because the sun is higher in the sky, therefore giving us more heat energy from the more direct- light 9. At what point during the year do you think the Earth is closest to the Sun? Furthest from the Sun? Closest in December, farthest in June Questions 10-11 10. What causes the seasons to occur on Earth? The tilt of the Earth causes the Sun to hit Earth at different angles. The higher the angle of the Sun, the warmer the surface temperatures will be. The revolution of Earth makes the seasons change. 11. What is the difference between rotation and revolution? Rotation is spinning on the axis and results in one day; revolution is going around the sun on our orbit and makes one year Reflection • Write a paragraph on the back of your paper that describes how your thinking has changed over the past three weeks.
