Strand: H The Nature of Science Standard: 1 The student uses the scientific processes and habits of mind to solve problems. Florida Science Benchmark: SC.H The student uses the senses, tools and instruments to obtain information from his or her surroundings. Florida Science GLE: SC.H uses a variety of tools (for example, thermometers, magnifiers, rulers, scales, computers) to identify characteristics of objects. Answer Strategy: A telescope makes things that are far away look closer. You can use a telescope to look at things in the sky. The picture shows a telescope. 3 The correct answer is A (Stars are hot balls of gas.). Strand: B Energy Standard: 1 The student recognizes that energy may be changed in form with varying efficiency. Florida Science Benchmark: SC.B student knows that the Sun supplies heat and light energy to Earth. Answers to Page 80 4 The correct answer is F (The Sun lights the Moon.). and the universe and how this affects life on Earth. student knows that light reflected by the Moon Florida Science GLE: SC.E (Previews grade 2) knows that the Moon moves around the Earth, the Earth moves around the Sun, and the Moon is visible when it reflects the light from Answer Strategy: The Sun s light shines on the Moon. You only see the part of the Moon lit by T79

2 5 The correct answer is A (day). The Answer Strategy: Earth makes one rotation every day. Earth s rotation causes day and night.

You see the Moon more often at night. Answers to Page 81 7 The correct answer is D (rotation). The Answer Strategy: Earth is always moving. Earth turns around and around. This is called rotation. 8 The correct answer is H (The Sun is bigger than Earth.). Florida Science GLE: SC.E K.1 (Reviews grade K) knows that the position of the Sun in the sky appears to change during the day. Answer Strategy: The Sun looks small because it is far away. The Sun is bigger than Earth. 9 The correct answer is B (the rotation of Earth). T80

Stars look tiny because they are very far away. 15 The correct answer is B (You only see the part of the Moon lit by ). student knows that light reflected by the Moon Florida Science GLE: SC.E knows that the amount of light reflected by the Moon is a little different every day but the Moon appears the Answer Strategy: The Sun s light shines on the Moon. You only see the part of the Moon lit by T82 Answers to Page The correct answer is G (one). and sunset is due to the rotation of Earth every Answer Strategy: Earth s rotation causes day and night. Earth makes one rotation every day. 17 The correct answer is shown below.
