Welcome to group 6, period 1, wiki space. =)** Halie, Megan, Nick, and Kyle are cooler than cool. Word up =)
 * Hey there kids,

4/18/08 Hi. I'm Phosphorous. You'll find me hanging out in the dark. I'm used to make glow-in-the-dark clocks, watches, and toys. My favorite job is entertaining the world by making the image on the tv screen. kbye.

Yooooo, my name is Helium. I like flying in blimps and going under the ocean with scubadiver's oxygen tanks. I also like celbrating birthday's with balloons. I usually go with astronomers to help eliminate space noise on thier detectors. I am a very helpfull person!! =D

Hi. my name is Zirconium i am used to make rods at nucular power plants. also i make jerwlery and space vehicle parts.

.Hi my name is Cobalt, one of my favorite things to do is to make things look blue. I am also used to make some magnets. I can be used to help people by being used in x-ray machines and can treat cancer patients.

Purpose-How does dissolving copper sulfate affect the temperature of the sulution. IV: amount of copper sulfate. (g) DV:temperature. (c) Constants: same amount of water, same chemical, same equipment, same amount of time between when we check it, same starting temperature.

Copper sulfate is soluble in water. Zinc oxide was insoluble in water. Water was the solvent in our lab. Sulfur,sucrose, zinc oxide, copper sulfate, sodium chloride was the solutes in our lab. Copper sulfate made a solution when it was mixed with water. Sucrose dissolved easily in water.

Define: soluble- The abilty to dissolve in another substance.

insoluble- When a substance cannot dissolve into a solvent.

solvent- The substance that a solute is dissolved into.

solute- The substance that is dissolved to make a solution.

solution- A mixture that apperas to be a single substance but is actually particles of two or more substance that dissolve into each other to form one solution.

dissolve- To cause to pass into solution.

Chemistry Unit Kyle- I would like to mix chemicals

Nick- I would like to have a lot of experiments and mix chemicals.

megan- I would like to learn more about chemistry

Halie- I would like to learn more about mixng chemicals to create new chemicals. Facts from lab: Translusent means for a substance to have color. Transparent means for a substance to be clear, or see through. Another word for uniform is homogenius.

2/7/08 We are conductiong an experiment to find out where kinectic energy comes from. Hypothesis: When the car is rolling down the rulers, it is creating thermal energy. An energy conversion occurs and the energy turns into kinetic energy. IV: Height of ramp, length of ramp, mass of cart, weight of car. DV: Mass of Patrick Car: 33.2g ; 0.0332kg ; 0.332 newtons. Starting point: 10 cm Height of starting point: 15cm = 0.15 meters End point: 90cm

__Warm up__

Questions: 1.Which of these has the highest heat capacity? a. water b.silver c.glass 2.What is the difference between temperature, thermal energy and heat? 3.When a substance is cold, are particals moving fast or slow? 4.What are the differences between a conductor and an insulator? 5.Materials that warm up or cool down have a specific......?

Answers: 1. a 2. temperature is the average speed of particals. Thermal energy is the total speed of particals. Heat is the transfer of energy between two objects. 3. slow 4. A conductor conducts thermal energy very well and an insulator does not conduct thermal energy well. 5. Heat capacity

Abzolute is the lowest possibe temperature on the kelven scale. Thermal energy flows between objects that differ in temperature. Conduction is through direct contact. Convection is the movement of gas in liquid. Radiation is through space. Specific heat capacity is the energy needed to change the temperature in a object. A higher specific heat capacity needs lots of enegy to change the temperature, low does not Liquid has a definte volume but not definate shape. Charles Law states that a voumle of a gas increases as the temperature increases if the pressure does not change.


 * __Summing Up chapter 9__**

Energy is the ability to do work. Work occurs when a force causes an object to move in the direction of the force. Work is the tranfser of energy. Work and energy are expressed in the same units [joules]. Kinetic energy is the energy of motion. It depends on speed and mass. Potential energy is the energy an object has because of its position or shape. Weight and height effect gravatational energy. Weight is expressed in newtons and height is expressed in meters. Mechanical energy is the total energy of motion or position of an object. It can be all potential energy, all kinetic energy, or some of both. Energy takes different forms, these forms of energy include: thermal, chemical, electrical, sound, light, and nuclear. Thermal energy is the total energy of the particles that make up an object.(kinetic) Chemical energy is the energy of a compound that changes as its atoms are rearranged to form new compounds.(potential) Electrical energy is energy of moving electrons.(kinetic) Sound energy is caused by an objects vibration.(kinetic) Light energy is produced by vibrations of electrically charged particles.(kinetic)

Energy resource - A natural resouce that can be convverted by humans into other forms of energy. Nonrenewable - A natural source that cannot be replaced or only over millions of years. Renewable - A source that can be replaced over a short period of time. Fossil fuels - A nonrenewable source that forms in th earth's crust from the buried remains of once-living organisms.
