2How can a person use sound to send a message to someone far away?
Show answer & explanation
Answer: By shouting or ringing a bell
Shouting or ringing a bell uses sound that can travel far to send a message. Sound can travel through the air over a distance. A loud shout or a ringing bell makes sound that reaches far away. Drawing, waving, and nodding are seen with the eyes, not heard with the ears. Students may choose waving because it is a way to communicate, but waving is seen, not heard. The question asks about using sound.

3When you gently pluck a guitar string, what makes the sound?
Show answer & explanation
Answer: The string vibrating back and forth
A plucked string vibrates, and that vibration makes sound. Sound comes from things moving quickly back and forth, called vibrating. When you pluck the string it shakes fast and makes the air move, which we hear as sound. Students may think color or temperature makes sound, but only vibration, or fast movement, creates sound.

4A shadow is very short at noon when the Sun is high, but very long in the evening when the Sun is low. What causes this change in the shadow's length?
Show answer & explanation
Answer: The position of the light changes
The shadow changes length as the position of the light changes. A shadow's length depends on where the light comes from. When the Sun is high overhead, the shadow is short. When the Sun is low near the horizon, the light hits the object from the side and stretches the shadow long. Students may think the object itself changes size, but the object stays the same; only the light's position changes.

5Which object gives light to the Earth during the day?
Show answer & explanation
Answer: The sun
The sun lights the sky during the day. Think about what you see in the sky when it is bright outside. The sun rises in the morning and gives light and warmth all day. The moon and faraway stars are usually seen at night, and a cloud does not make its own light. Students may pick the moon because it also appears in the sky, but the moon is mainly seen at night and does not make the day bright.

6What causes an object to make a sound?
Show answer & explanation
Answer: It vibrates, or shakes back and forth
Objects make sound when they vibrate. Sound comes from vibrations. When something shakes quickly back and forth, like a drum top, it makes the air move and we hear a sound. Students may think a still object can make sound, but an object must vibrate to make sound.

7Why does the ground feel warmer in the afternoon than early in the morning?
Show answer & explanation
Answer: The sun has been warming it
The sun warms the ground during the day, so it feels warmer in the afternoon. As the sun shines through the morning, it heats the ground more and more. By afternoon the ground has soaked up much warmth. The moon and stars do not warm the ground. Students may think wind stopping makes it warm, but the sun's heat is the real cause of a warmer ground.

8Which material can bend the most easily?
Show answer & explanation
Answer: A rubber band
A rubber band bends the most easily. Test each item by trying to bend it. Glass, metal, and wood keep their shape and do not bend by hand. A rubber band stretches and bends easily, so it is the most flexible. Students may choose the metal spoon, but a spoon is stiff and does not bend when you push on it lightly.

10Which body part does an animal mainly use to see?
Show answer & explanation
Answer: Eyes
Animals use their eyes to see. Eyes gather light so an animal can see the world around it. Feet are for moving, a tail helps with balance, and the stomach is for digesting food. Students may confuse body parts, but only the eyes are used for seeing.
