To test my experiment, I used similar instruments to a piano Mr. Beard provided for me such as, the cello, cymbals, and the triangle. I used those instruments because you can see them vibrate as you can on a pianos string. A cello is mostly like a piano because it has strings that vibrate when you pull them with a bow, pluck them with your fingers, or strike them with something. You can also do that to a piano. The triangle and cymbals are also similar to a piano, but not as much as the cello. The triangle vibrates and makes sound when it is stricken by a metal stick. The cymbals vibrate when something strikes them, or if they crash together. One thing all instruments have in common is that they don’t vibrate unless they are acted upon by an outside force. The next thing I did in my experiment was compare the vibrations in those instruments using a small force, and a large force. I used a timer to time how long I heard each instrument vibrate. Amari

=My Experiment=

For my experiment I got an empty mechanical pencil and a paper clip taped to an eraser holder that were both 4 grams and dropped them both from a meter. This explains that things that seem light and the things that seem heavy really weigh the same and will hit the ground at the same time. The 2 items hit the ground close to the same time. Also their speed was close together too. Josh

=My Experiment=

For my experiment I got a fishbowl and filled it with water. Then I got a magnetic ball and dropped it in the bowl. Then I got a strong magnet and moved it around the bowl. The magnet represents the moon’s gravitational pull. The magnetic ball represents the earth. The water represents the ocean. This shows the tides. Luke
