Sound Exploration
First graders are beginning a wonderful physical science exploration this week in the area of Sound.
Here are some of the key verbs and nouns of the unit:
VERBS (What students will be doing):
- Plan and conduct investigations: Think and do a project to answer questions
- Provide: Supply or have to share
- Vibrate: When things shake quickly
NOUNS (What students will be learning about):
- Sound: Energy from vibrations that you hear
- Matter: Stuff that everything is made of
- Evidence: Information that proves a point
- Material: What something is made of
We look forward to having some help at our Science lab in the coming weeks! If you are interested in joining us, please email our room parents and take a look at this

As students are learning about Sound over the next few weeks, here is some background for your home conversations:
Sound is created by vibrating objects. Unlike water waves or vibrations of a string, which move up and down as they travel sideways, sound waves travel in the direction of their motion, compressing and rarefying (expanding) the air as they go. If there is no air, like in the vacuum of space, there is no sound. Sound waves travel when matter is present in the gas, liquid or solid phase.
There are many different types of sounds. Sounds can be loud, like a siren blaring, or quiet, like a whisper. The more air that is moved, the louder is the sound. Loud sounds have higher amplitudes and quiet sounds have lower amplitudes. Higher pitches vibrate the air at higher rates than do lower pitch sounds. Sounds can be high-pitched, like an alarm, or low-pitched, like a tuba; these are examples of high frequency sound waves and low frequency sound waves, respectively (Stemscopes Curriculum).

Feel free to explore for homework options this month!
