What are vibrations?
Tap to reveal answer
Vibrations are quick back-and-forth movements that create sound waves that travel to our ears for us to hear. An example would be the vibrate setting on a cell phone or holding a ruler off a desk and flicking it so it bounces back and forth on the edge of the table.

Which investigation would work best to see how vibrating materials make sounds?
Which investigation would work best to see how vibrating materials make sounds?
Tap to reveal answer
The best set-up of an investigation to see how vibrating materials make sounds would be to use a tuning fork. Once the metal tuning fork is hit on the best students can visually see the fork vibrating and can move their ears closer to listen. Students will be able to see and hear how the vibrations work.

Tap to reveal answer
In science, data and observations are collected and used as evidence to support or not support a hypothesis (what the scientist thought was going to happen). Evidence is used to support ideas, arguments, opinions, and thoughts. A scientist cannot make a claim without evidence to support it.

Sadie has to design a device that uses sound to communicate over a distance. She comes up with what she thinks is a great idea.
How could she test her design?

Tap to reveal answer
The best way for Sadie to test her design is to build it and use it. If she makes it and finds some things that need to be fixed or changed, she can work on her design. If she never actually builds it, she won't know if it works.

Reina has to design a device that uses sound to communicate over a distance. Her teacher lets them start by picking one object. Which object would be the best for Reina to choose to communicate over a distance?

Tap to reveal answer
The object that would be most useful for communicating over a distance would be the whistle. The other objects make noise, but they are quiet and may not be heard depending on how far the teacher separates the students. Reina could make different sounds with the whistle to communicate, so it could be an excellent place to start her device.

This statement is true. The best way to start the design process would be to ask questions about what you need to make, observe other devices already created or designed, and to gather information about needs and how things work.

Tap to reveal answer
The most important aspect listed for a device trying to communicate sound across a distance would be how loud it is. If the sound is too soft or quiet, no one will hear the message being sent. The "prettiness" of the sound and how heavy it is are not the most important characteristics.

Tap to reveal answer
A handbell would be the best device to choose if you were trying to communicate with other people using sound. A whisper does make a sound, but it will not travel far because it is so soft and quiet. A sign is a great way to share your location, but it does not use sound. A handbell is loud and could easily be heard.

Vibrations cause all sounds. When something vibrates sound waves are sent through the air to our ears to hear. Without vibrations there would be no sounds.

Tap to reveal answer
We can change the volume or pitch of something when we change the way it vibrates. Volume is how loud or soft something sounds and pitch is how high or low the sound is. By making something vibrate more or less, faster or slower, we can change the way it sounds.

What would happen if you put a sheet of black construction paper in front of a flashlight?
Tap to reveal answer
If you tried to shine a flashlight through a sheet of black construction paper, it would block the light. Light would not be able to pass through to the other side, and it would not be reflected. Something dark in color and also a thicker material like construction paper would block light from passing.

If I were to place the chocolate bar in the Sun, it would melt due to the heat. The rays of light from the Sun are not only bright but hot. Chocolate is something that melts, and sitting under warm light would cause that to happen.

What makes a shadow?
What makes a shadow?
Tap to reveal answer
A shadow is created by blocking light. Shadows need a light source like a lamp, the Sun, or a flashlight and an object to block the light. A simple way to see a shadow is standing outside during the day and looking down! Your body blocking the sunlight will create a shadow of your figure on the ground. Another easy way to make a shadow is by putting your hands in front of a flashlight in a dark room.
