My Voki:

== In the real world scientists help people solve one of the most hardest expeirements, and that helps them learn more about that certain odject. Scienctists also make new medicines to help people get better when there sick. When they try it on someone and it works they give it to a hospital and then they start approving it. ==

== The purpose of this site is that were teaching other people about science, what science is, and how science works. And also that other people know how there are other ways to learn and figure out to work science labs and science experiments. ==

== This is my " Life As A LION " poster. This poster shows my life, and what i love to do. The multimedia tool that i used for this was a powerpoint. I used this because it sometimes is easier to save as any type of document. the reason why i posted this was because i want you to know more about me. I want this reader to really know what I do in my life and why I do it. ==

= The History of Measurement = = = = In 1400 b.c Egyptians had introduced a new measurement/weighing tool. This tool was a simple balance with a pointer. Before the Egyptians made this tool they had to standardize the measure of the length called a cubit. This was orginally defined by using the length between the elbow and the top of the middle finger. Alot of countries back in the day made many different measurement tools. In Lydia, during 640 b.c., they used the units of weight to weigh gold and silver to make sure that they had gotten the correct amount. In China during 200 b.c., they would multiply the length, width, and the height. Earlier the Chinese were the first ones to use decimal notations, which is based on only 10 digits. In Central Europe the emperor was set as a standard unit of weight. This was called the "Karlespfund" which meant "Charlemagnes Pound". In England they had used it to measure part of an area. In Germany, Gabriel Fahrenheit had invented the thermometer to be able to measure the temperature. In France, 1983, a meter was defined as the distance light travels in a fraction of a second. = = Reflection on the Changes in State and Viscosity Lab (What I Learned.....) = = = = = = Reflection on the Properties of Gases Lab = = media type="custom" key="10941120" = = =

Lab Report!
= = How does the temperature of the surroundings effect the rate at which the ice melts?

Materials: = =
 * 1) Thermometer
 * 2) 2 plastic cups, 100 mL Celsius
 * 3) Ice cubes
 * 4) Warm water 40 degrees Celsius
 * 5) Room temperature water

= = Procedures: 1. Make a table with the correct data 2. Fill up one cup with the room temperature water. 3. Measure what the temperature was in the cup before you added the ice cube 4. Once you are done recording the room temperature drop the ice cube in the room temperature water. 5. Record how long and what the temperature was at the end. 6. Now add the warm water. 7. Then when you done use the steps 2-5 but ONLY with __warm water.__ = =

= = Here is my Data Table: Temperatur(Celsius) || Final Temperature (Celsius) || 39 Seconds 21 milliseconds || 14 degrees celsius || 50 seconds 85 milliseconds || 23 degrees Celsius || = =
 * || Beginning
 * Cup 1 || 6 minutes
 * Cup 2 || 1 minute
 * Cup 2 || 1 minute

Temperature(Celsius) || Time to Melt || Final Temperature(Celsius) || = =
 * || Beginning
 * Cup 1 || 24.9 degrees Celsius || 300+ seconds || 12.9 degrees Celsius ||
 * Cup 2 || 42.3 degrees Celsius || 131 seconds || 24.9 degrees Celsius ||
 * Cup 2 || 42.3 degrees Celsius || 131 seconds || 24.9 degrees Celsius ||

Results: Me and my group notice that the ice had melted in warmer water quicker then it did when it was surrounded in room temperature water. The ice melted 5 minutes quicker wuth the it water then it did with the cold water. For the final substance it was in the warmer range. When it was in the cooler water the temperature had dropped lower. The degree difference was in the 11 range.

Conclusion: From doing this lab report i have come to my conclusion that ice ,being a different substance, can melt with a warmer substance being warm or room temperatured water. With the warm water the ice had melted faster because the qater was heated before being out inside the beacker. Before we pur the ice cube in the warm water, we had to see how hot or warm the water was before putting the ice cube in. You will be able to see how warm the water was before adding the ice cube.

Discussion: There might have been some ways that i had gone wrong with in the lab. I never noticed how long it took for just one single ice cube to melt in one beaker 5 minutes earlier then the first one did.

Here is Lithium. What we did in science class last week was we got to make out own elements from the periodic table. this was called the Borh's Lab.

Properties of Metal Paragraph
This past week we have been working on the properties of metal. The properties of metal are shininess, malleable, ductile, and hardness. Malleable is a term used to describe the material that can be hammered or rolled into shape. Ductile is a term used to describe a material that can be pulled out into a long wire.



Alka Seltzer Lab:

The purpose of this lab is that we had to collect the data of the Alka Seltzer. We had 6 cups. We also had room temperatured water, and heated water. What we had to do was use a stop watch and see how long it took for the Alka Seltzer to dissolve in the water. A chemical reaction is a process at which substances undergo chemical changes, forming new substances with different properties. The evidence that is seen in order to dertermin if a chemical reaction has taken placeis when the chemical bonds are either formed ir broken apart. My original prediction was that the Alka Seltzer would melt faster with the room tempertaured water but it actually melted faster with the heated water. The number of trials that i did in the lab were only about thwo or three. Trial number one was withwarm water. With the warm water it was 81.9 degrees. It took 18.9 seconds for the Alka Seltzer to dissolve. The room temperature was 17.2 degrees. And it took 56.5 seconds to dissolve. The secon trial was with ice water, the temperature of the water was 7.1 degrees. With this temperature it took 2:24.2 minutes/seconds to dissolve. The evidence that I saw in each trial was that to be able to dissolve something you have to have the right temperature for it to be able to dissolve in that certain temperature. Why did we have to have a certain temperature for the Alka Seltzer to dissolve? Why did we have to time it? Other solutions will occure if you have the right tools and you take notes to keep task on what your doing and how you do it. It was evident that the purpose of the lab was met because we were ging to find out how long it would take for the Alka Seltzer to dissolve in room temperatured water, heated water, and ice water.

 * What Mrs. Delucia gave us this week is called a popplet. This is something that we can use to share with our classmates to show them what were doing and how were doing it so they can also learn themselves, how to use a popplet. So Mrs. Delucia gave each of us a molecule, my molecule was propane. Now what i had to do was find out all this information about propane like the atomis=c structure, the history, and the type of bond. I thought this was a really good source to use!(: **======

====** So what we did in science yesterday was a chemical bonding activity. What you have to do is if like lets say Propane has C3H8, you put the 3 carbons in the middle and the 8 hidrogens around the carbon. I really liked this activity cause it ade me understand the names and how to set the up more easily then I did before.(: **====


 * Mixture Lab~**

media type="custom" key="16201290" Scratch
 * So what we did in science the other day was we did a lab experiment on these substances: sugar, salt, vinegar, rubbing alcohol, pepper, powdered sugar, baking soda, corn starch and vegetable oil. What we had to do is find out if any if these substances were soluble or non soluble. My hypothesis was that the liquids would dissolve faster than the solids. My hypothesis was wrong. The reason why I was wrong is because the soluble substances can dissolve faster. The substance that appeared to dissolve better is the solid. The water was polar. The observation that indicated how they dissolved is that some substances can dissolve faster than the other substances. I think that some of the reasons that the substances didn’t respond is because the water was a certain temperature and some other substances can dissolve faster than others. **
