What is Science? Science is the study of a certain Subject. One type of science is Rocket science, which is the study of how to make a Rocket reach orbit with the less amount of gasoline, and the most secrured way. One other example is life Science, Where You Study how Life...works; like How makes something a living Organism.

What do Scientist do in the Real world? In the real world scientist Find ways to advance in their subject. War Scientist Find out how to make More advance weaponary. On The Other Hand, a Life Scientist would Study how the Earth Works.

What do you do in Science class? In science class we do many Experments. Also, in science We talk about the Question, when a question is asked, and Do labs.

What is the purpose of this site? The Purpose of this site is to expand our learning. Also, it is for learning off of each other.

History of Measurement:

One of the first measurement, was the cubit. It was invented by the ancient egyptians. Second Know measurement was a //talent//, and it was about 25 kilograms. Third was a //Mina;// and that was about 500 grams. Measurements are important, because they help us know how much we need of something.



In this Lab we basically learn about viscosity. I learn that ethanol and Water have about the same amount of viscosity. Honey has the highest amount of viscosity out of all the examples.Also, I reviewed That Solids Hardly move, Liquids Move more freely, and Gases Move rapidly.The Substance That we Test were a Crystal Substance, Purple substance, and a Green Substance. The Crystal Substance Melted at 0* and started boiling at 100*. The Purple Substance Melted at 47* and Boiled at 143*. Lastly, Green substance's melting point is 30* and it's Boiling point is 121*.

Refection: In this lab we Learn how all the variables can effect how the outcomes...out.I learned that when temperature increases Volume will expand, and Pressure will increase. On the other hand, When temperature decreases Volume decreases, and pressure decreases. Another thing I learn was, When Adding particles Volume will Increase, and Pressure will also Increases. When Particles are removed Volume decreases, and pressure decreases.

Lab Report: Introduction- Before The lab we went over What we were going to do. We guessed What we thought was going to happen. We gather Instructions on what to do. Then We Said What our Hypothesis was.

Problem- How Ice would react to Heat in Different water temperature.

Hypothesis- Ice will melt in warmer Water.

Materials- 1.Thermometer 2. 4 Glass Cup 200 mL each 3. 2 stirring Rods 4. 4 ice cubes 1 for each cup 5. 2 room temperature waters and 2 hot-warm waters 6. Stopwatch

Procedure- 1. Get a Piece of Paper and draw a Graph on it(a 9 block Graph) 2. Fill up One of the cups up to 100 mL with water 3. Record the temperature of the water 4. Drop a Piece of Ice in the water and record how long it took to melt 5. Record the Temperature after the ice melts 6. Repeat steps 2-5 3 more times

Data and Observations- Cup 1=Beginning Temperature-24*C;Time to Melt-4 minutes 5 seconds;Final Temperature-16*C Cup 2=Beginning Temperature-42*C;Time to Melt-2 minutes 10 seconds; Final Temperature-30*C Cup 3=Beginning Temperature-21.1*C;Time to Melt-300+ Seconds;Final Temperature-9.6*C Cup 4=Beginning Temperature-41*C;Time to Melt-184 Seconds;Final Temperature-22.6*C

Result- My Hypothesis was Correct. The amount of trials we did was 1-2 each. The Instruments we used were Beakers, Thermometer, and a prone. What we were trying to measure was the Temperature of the water. The variables we were looking at were Different room temperatured, mis-reading the Thermometers. Water was melting the ice. The time that varied was about 10 minutes.

Conclusion- Look at this lab, I would say this would be One of those labs that You secretly Learn something. I did Enjoy This Lab, because I would always stereo type it and thought even though a water is hotter I thought it would be the same temperature. In Conclusion My hypothesis was correct. Ice will melt in warmer Water. I found out that water

Discussion- The Experiment was very easily "Mess up-able." You Could never know if you ruined the lab. You use this lab everyday. Some source of errors would be not stopping the watch in time. The Size of the ice could affect the result. How long the ice was sitting out could affect the result.

Reflectionz; This Lab help us understand how elements are made, and their structure. This was rader Easy.

Metals are the most popular element on the Periodic Table. Chemist classify elements as Metal base on Properties such as Hardness, shininess, malleability, ductility. Metals a wide of Chemical Properties. There are many Different types of metals, they all are very simplely to each other.

One Of the types of metals is the alkaline earth metals. Alkaline Earth Metals are located in Group 2(Column 2). Two of the most Common Alkaline Earth Metals are magnesium and calcium. They Lose Valence electrons [|easily]  in chemical reactions. They are as reactive as the Element to their left.

In conclusion, Metals Make up most of the periodic Table. Metals are Very sutured. Metals are really reactive when it comes to other elements.

The Purpose of the lab was to see chemical reaction in action.chemical Reaction is the process at which substances under go chemical changes, forming new substances with different properties. The evidence of chemical reaction happening is the capsule being dissolved. The Original prediction was that the capsule in hot water was to dissolve 5 times faster then the one in room temperature water. The number of trails we had were three. Element Popplet: media type="custom" key="12372092" Summary:

In Class we were assigned a Compound which we had to research and make a model of, to show our research we use a new web tool (to us) called Popplet. Popplet wasn't a hard web tool to use, because it was like a web tool we used before, Prezi. I had to problems creating a Popplet of Carbon Dioxide, because of how easy the tool is. We had to research four parts for the Popplet, The type of bond it had, the history of the compound, the Structure, and examples of the compound. Some thing I learn from this experiment is that Carbon Dioxide is a covenant bond which means it share atoms. In conclusion, This experiment/project was very interesting.

Conclusion: In this lab we're testing what substance was soluble and what wasn't soluble. In the beginning of the lab we got a paper, and on the paper it asked us,"Which substance dissolves more easily: solid or liquids?" My Hypothesis was that Liquid was going to be faster because I thought liquid was already half way done with the process of the mixture. After the lab, I found out that neither was faster they both dissolved at about the same time. Water is a polar bond, so it mix easily. The molecules surround the ions. I found out that Some substance dissolve and some don't. media type="custom" key="16248474" Scratch Project media type="custom" key="18357304"
