Mills Creek Canyon


So, on April 29th, yesterday, Mr. Olson conducted a field trip up the hill at Mills Creek Canyon. The experience of trekking along in the wilderness was very exhilarating. We passed by many species of plants, and soon came across poison oak, which was thankfully labeled. Well anyways, there were many insects, animals and other wildlife available for us to see. One of the more interesting parts of the trail was the creek. This area does not seem to have a lot of creeks, so the sight of running water was very pleasing to see. However, the route to the creek can be hazardous at times, but is very worth it. So, I will let you see how we got there, and the basic route of the trail once in Mills Creek Canyon.

IProposeWe experiment with air pressure


Materials: Vacuum, Alarm, Feather, Metal Washer, Magnet, Marshmallow, Goggles

Procedure:

Flip the plastic shield of the vacuum over. Place the feather underneath the metal washer in the center of the shield. Then place the magnet beneath the shield so the feather is held by the metal washer inside. Place the shield on the vacuum. Turn on the vacuum. Record Observations. Turn off vacuum.

Place marshmallow in the center of the vacuum. Place shield on vacuum. Turn on vacuum. Record Observations. Turn off vacuum.

Place Alarm in vacuum. Turn on Alarm. Place shield on vacuum. Turn on vacuum. Record Observations. Turn off vacuum.

Safety Precautions:
  • Wear goggles in order to protect your eyes if anything unexpected happens
  • Be cautious in operating the vacuum
Scientific Principles
  1. Increasing Air Pressure dampens sound
  2. Increased Air Pressure does not provide air resistance
  3. After increasing air pressure, all the air in the marshmallow will be lost, shrinking the marshmallow
