//__H E R E *I S*O U R* W I K I S P A C E*__// Jordan, Nick, Jess, and Sarah. __**12-13-07** Salt and Ice Experiment__ The data shows that for the most part, the more salt we added, the faster the ice melted. We have on outlier in our set of data. When we used three grams of salt, he ice took longer to melt than when we used two grams of salt. When we used one gram of salt, the ice took 13.57 minutes to melt, but when we used five grams of salt, it took 7.23 minutes to melt. The different between the times are 6.34 minutes. Our hypothesis was supported by the data, because the ice melted fast when there was more salt. I think this happened, because when you add salt to ice, it disrupts the equilibrium. It dissolves into the ice, and the rate of freezing slows down. The rate of melting is not affected, and since it melts faster than it freezes, it changes state to a liquid.

Plasmas Definition: The state of matter that does not have a definite shape or volume and whose particles have broken apart; plasma is composed of electrons and positively charged ions. Plasmas conduct electric current while gases do not. 99% of the universe, including stars, is made up of plasma. electric and magnetic fields are used to contain very hot plasmas. Some natural plasmas are lightning, fire, and the aurora borealis Some artificial plasmas are found in fluorescent lights and plasma balls Artificial plasmas are created by electric charges through gases. Auroras form when high-energy plasma collides with gas particles in the upper atmosphere

__**10-19-07** Why do boats float?__ The data shows that clay boats that float probably displace about the same amount of water as their mass. When using 10 grams of clay, the average amount of water displaced by floating boats is 10.7 grams. Most of the boats that floated also had thinner, curved walls. The average amount of water displaced by sinking boats was 6.2 grams, however. That is why the clay boats floated or sunk.

We are working and trying to figure out more information on the Mission Possible mystery. We are looking up information on all of the suspects. The group has worked very hard on trying to solve this particular mystery and we think we have figured out why one boat floated and the other boat sank. Shaping the steel into a hollow form increases the volume occupied by the same mass, resulting in a reduced overall density of the ship. The ship is now less dense then water therefore it floats.

__**10-10-07**__ Summary of volume and mass The data shows no correlation between the volume and mass of different objects. In one case, when the volume was greater and the mass less, the point on the scatter plot was much different than the point for an object with greater mass and less volume. This shows that there is no correlation between the volume and mass of different objects.

More notes for Mission Possible Investigation

Mass- - the amount of that something is made of - stays the same unless the amount of matter changes - mass is conserved - basic SI unit is kilograms - measured with a balance - measure of inertia

Density- - The mass per unit of volume - The ammount of matter in a given space - To find the density, divide mas by volume - Density is always the same at any pressure or temperature - The density of each substance is usualy different

Weight- - Object in fluid will sink if it is heavier than the fluid - The basic SI unit for weight is Newtons. - Weight is the measuer of gravitational pull on an object - As gravitational pull gets stronger weight increases

Malleability- - the ability to be pounded into thin sheets The shape of a metal can be changed without breaking because the metallic bonds occur in many directions

Gravity-affects everything with mass

Suspects… Density-some of the clay is denser than water so it would sink State- exists as a solid Volume- the mass Shape-the clay boat

Is mass conserved? Mass was conserved in this experiment. The masses of alcohol and water measured seperately averaged about 45 grams. Massed together they were also about 45 grams. One group actually had no change in mass at all. This shows that mass is conserved.

__Alice and metricland__

Characters: Alice and the big fat purple cat named Chester.

Problem: Alice went to her unbirthday party and drank some tea Since the tea had a volume of 10 centiliters. She shrunk from 1.5 meters to 1000 milliliters, or 0015 kilometers.

Solution: the big fat cat appears and explains to Alice that she must drink another cup of tea with a volume of 10 centiliters. After that she goes back to her normal height of 1.5 meters after drinking the tea.

Once upon a time there was a girl named Alice. She was sitting by a tree reading a poetry book and she went to walk over to go get some ice cream when…she fell into a hole. But this was no ordinary hole this was the portal to an unknown world. Alice is confused because she doesn’t know where she is who she’s around and what she’s around. Then, she sees a fat cat. She goes up to the cat to pet it and the cat startles her by talking! “Hello my name is Chester what’s your name?” “You can talk?” “Yes, why is that weird?” “Well a little bit” “Sorry I didn’t mean to startle you” “It’s okay” “May I ask you a question?” “Sure. What is it?” “Where am I?” “Why you’re in metricland” “metricland?” “Yes metricland. Now I have a question for you. Do you want to go to an unbirthday party?” “What’s an unbirtday party?” “An unbirthday party is when it’s not really your birthday but we celebrate like it is your birthday” “Oh okay sure!” “It starts in one hour.” “Okay”

One hour later…… “Well hello there Chester” “Hello. Have a seat.” Alice discovers that she is thirsty. She sees a cup of tea and she looks over at Chester about to ask if she could have some tea but he was welcoming his other guests and she just drinks a cup of tea. The volume of this particular cup of tea is 10 centiliters. When all of sudden she shrinks! “Oh my goodness what just happened?” She asks herself. “I must get Chester’s attention and tell him to help me.!” “Chester, Chester, Chester!” “What? Oh my. Alice what have you done?” “I just had a sip of that tea over there and the next thing I knew I shrunk!” “Well it isn’t as bad as it looks and sounds.” “All you have to do is drink the same amount of tea and then you will return to your normal height.” “Oh no!” “What is it Alice?” “There is only 5 milliliters of tea left.” “ Well I will go see if I have any more of that tea.” Bang, bang, boom, clash! You can hear Chester fumbling around in his kitchen. “You’re in luck I have I some!" Alice drinks the remaining amount of the tea and then drimks the new batch. She is amazed when she feels herself getting taller until she gets back to her normal height. “Oh thank you so much Chester! You’re a life saver literally.” “I am happy to help” Alice then realizes that she has to go to the bathroom. “May I use your bathroom?” “Why yes of course. Go down the hall and make a right.” Well little did Alice know but she took a wrong turn and she got whisked away. She opened her eyes and noticed that she was in the United States again. “Oh my I didn’t even get to say goodbye to Chester” …
