    Entropy- 2nd law of thermodynamics (change in heat)
    Entropy is a measure of disorder in a system. For example, the higher the disorder, the higher the entropy value.

    First Law of Thermodynamics- The increase in the internal energy of a system is equal to the amount of energy added by heating the system, minus the amount lost as a result of the work done by the system on its surroundings. As stated:This is the conservation of energy which means that energy is never created or destroyed, only transfered.

    Earth Day with Mono Lake
    >
    > I'm checking with you to see if you and some of your students would
    like to staff a Mono Lake booth at the Central Basin Municipal Water
    District's Earth Day, Saturday, April 12, around 8:30 AM-3 PM. It
    will be in Pico Rivera. I did it last year and I've been invited
    again this year but I will be out of town on April 12 so I thought
    I'd see if you were interested. I can provide an orientation,
    materials, and a Mono Lake water kit if you decide to go for it. You
    all are free to do what you want to with it. I think you are one of
    the best qualified groups to do this. You all really got what Mono
    Lake is all about. That's why I'm asking you.
    >
    > Do you want to check with your students and get back to me?
    >
    Thanks for considering this.

    Andy,
    >>
    >> I have been thinking about your desire to involve your class with the Arroyo Seco Foundation's cleanup efforts. You mentioned in your last e-mail the possibility of adopting a section of the arroyo. If you are really interested I would love to give you a section of the stream. I don't know exactly where your HS is located, but the area I have in mind is the soft-bottom section directly underneath the 134 fwy and Colorado St. bridge. It's one of the most celebrated parts of Pasadena, though it has not been kept up.
    >>
    >> While trash is a serious problem, I would hope that the team I assign to the area would specifically be looking to get rid of invasives. Trash will always be in the area, but invasives are something that can be systematically removed. Progress can be monitored and it is better for an ongoing project. After an initial work day getting them out, the team would come back once a month or every month to get any new seedlings out and follow up on any areas they missed
    >>
    >> If this interests you let me know. I can arrange for a work day with the city of Pasadena's assistance in the project. Though I'd love your group to take the lead on this, I would also like to have these work days open to the public in case other interested volunteers would like to help out.
    >>
    >> I imagine that this would be a weekend commitment for you and your students. If you'd rather work on a different task or work on a different part of the arroyo just let me know.
    >>
    >> We are having a trash cleanup in that same area next weekend. I will include the information below.

    {wrecking.gif} wrecking.gifThis Wrecking ball as it's hanging in the air has alot of potential energy beacuse of it's position, it has the potential to cause alot of damage to something, When the wrecking ball is let go it releases all the energy and become kinetic energy.
    Heat Capacity
    Heat Capacity is the amount of energy required to raise the tepmurature of a sibstance by on degree. The more solid a substance the higher heat capactiy it has. For exapmle: Water has a higher heat capacity thaan air because it will typically take longer for it to heat up when left near a heat source. We saw this in the Heat capacity, Co2, and Greenhouse Effect Lab. The air & the Co2 raised in tempurature when near a light, while the water's tempuratre stayed tha same.

    A projectile is an object in which only gravity act upon it. There are diiferent types of projectiles. An object can be dropped from its rest point. An object thrown vertically upward. An object thrown vertically at an angle. A projectile is an object that once thrown, dropped or projected it continues in its own motion and and the force acted upon it is the downward of gravity.

    Since there is gravity on Earth, if the monkey lets go of the tree he will fall to the ground. If the banana is launched straight at the monkey and the monkey lets go of the tree then he wont catch the banana. If there weren't any gravity, as shown in this picture, the monkey would stay in it's place and the banana would go straight to the monkey.
