Hypothesis: My hypothesis was that the students that played instruments would hear higher and lower than the students that didn’t, my hypothesis was correct.

1. Humans have a sense called hearing. 2. We use our ears to hear. 3. Ear hairs vibrate faster at higher pitches-vise versa.

Manipulated: 1. Different students (6 girls\, 4 girls) Responding: 1. Range of hearing (Hz) Controlled: 1. Tested at 3:00 pm 2. Online pitch generator\, 3. Computer speakers volume 4. Low to high pitch tested

1. Researched a student friendly online pitch generator 2. First I chose ten of my classmates and found out the ones who did or didn't play an instrument 3. Then I used random name selection to pick the students to test. 4. Using the same computer speaker volume at the same time of day 5. Tested from low to high pitches 6. Recorded the frequency in Hz

Musicians, from my research, hear high/lower pitches. While non-musicians can't hear as well as musicians. I think that musicians can hear high and lower pitches because they play instruments. But you can lose your hearing from playing insturments.

1. Doctor - to measure normal hearing
2. Hearing Aids companies
3. Comparing our hearing to other animal
4. 

1. Students are different distances away from the computer. 2. Not stopping the scale at the exact moment

1. Online pitch generator - https://www.szynalski.com/tone-generator/ 2. Ear diagrams - https://www.healthyhearing.com/report/53241-How-we-hear-explainer-hearing 3.

1. Mr. Kroeker - my science teacher 2. Janessa - my classroom helper 3. Mom and Dad - for their nudging
