TEST Question 1: A student classi�es a tortoise as a vertebrate. Which feature makes this classi�cation correct?
Choices:
1) It has a hard outer shell 2) It has a backbone 3) It lays eggs 4) It moves using four legs
Correct Answer: It has a backbone
Explanation: Vertebrates are animals that have a backbone. A shell, egg-laying, or number of legs does not determine whether an animal is a vertebrate.Page 1
Question 2: A dentist uses a small mirror to see the back of a tooth. What happens to the light that allows the dentist to see the tooth?
Choices:
1) The light is absorbed by the mirror 2) The light is re�ected by the mirror into the dentist's eyes 3) The light stops at the mirror 4) The light changes into sound at the mirror Correct Answer: The light is re�ected by the mirror into the dentist's eyes Explanation: A mirror re�ects light. Light from the tooth reaches the mirror and changes direction so that it can enter the dentist's eyes.Question 3: Three spoons made of metal, wood, and plastic are placed in hot water.Butter at the far end of the metal spoon melts �rst. What is the best conclusion?
Choices:
1) Metal transfers heat energy faster than wood and plastic 2) Wood transfers heat energy faster than metal 3) Plastic makes heat energy 4) All three materials transfer heat at exactly the same rate
Correct Answer: Metal transfers heat energy faster than wood and plastic
Explanation: The butter melting �rst on the metal spoon shows that heat energy reached it sooner. This means the metal transferred heat faster than the other materials.Page 2
Question 4: Which statement best explains why a liquid can be poured from one
container to another?
Choices:
1) Its particles are �xed in a regular pattern 2) Its particles can move freely over one another 3) Its particles are not moving 4) Its particles are very far apart like a gas
Correct Answer: Its particles can move freely over one another
Explanation: In a liquid, particles are close together but can move past one another. This lets the liquid �ow and take the shape of its container.Question 5: A �agpole casts a long shadow in the morning and a shorter shadow near midday. What is the main reason for this change?
Choices:
1) The Sun becomes smaller during the day 2) The Earth spins on its axis, changing the Sun's apparent position 3) The �agpole becomes shorter at midday 4) The Moon moves in front of the Sun every day Correct Answer: The Earth spins on its axis, changing the Sun's apparent position Explanation: Earth's rotation makes the Sun appear to move across the sky. As the angle of sunlight changes, the length and direction of shadows change.Page 3
