**In the Real World Scientists ...** **Scientists make observations. Scientists do experiments to answer any questions. Scientists can show us what other people can't usually.**

**In science class....** **In science class we do experiments and make hypothesis'. During science we'll make observations just like scientists and see what outcome of experiments and labs.**

**The purpose of this site is......** **The purpose of this site is to expand our knowledge of the topics we cover and to show what we've done. We can also learn new things and topics.**

**Measurements:** **Thousands of ears ago, things were diffrent. The world was flat, Carlos Sanatna was young, and people had to guess how tall they were. But now, there's measurements. Measurements really expanded from the beginning. They started out as weighing cake, measureing in inches or feet. Now, it can weigh a pick up truck and measure in centimeters, meters, or kilograms. Measurements were all around us from the beginning, we just didn't know it.**

**Reflection on the Changes in State and Viscosity Lab (What I Learned....)** **We did this lab on viscosity. We learned many diffrent things. One of these things being that when the temperature heats up, the viscosity slows;. When the temperature is cooled, the viscosity rises. Another thing is how viscosity can also do with the thickness of a substance. For example, honey is thicker than ethonal and the viscosity was higher in the honey than in the ethonal.**

Sir Isaac Newton

Sir Isaac Newton was born in 1642. He was an English natural philosopher. He was regarded as the most influential and original theorist. He was a creationist. He was less known for being a Christian than for being a scientist. Sir Isaac Newton made many great contributions to science. Some of which being his revolutions in mathematics.Newtondeveloped binomial theorem to create calculus. Calculus was one of his first revolutions in math. After a period of focusing on math, he went on to gravity. The people ofNewton’s time were very superstitious of what they didn’t understand. While they were afraid of comets,Newtonwas reasoning that comets and planets were made by the one, true GOD. He considered gravity afterward in 1684. He developed theories of universal gravitation. To prove these theories, he used the ‘inverse square law’. Isaac Newton developed the three laws of motion. WhenNewtoninvestigated or observed the planets, he saw God’s hand and wrote, **//“This most beautiful system of the sun, planets, and comets, could only proceed from the counsel and dominion of an intelligent Being. … This Being governs all things, not as the soul of the world, but as Lord over all; and on account of his dominion he is wont to be called “Lord God”, or “Universal Ruler”. … The Supreme God is a being eternal, infinite, absolutely perfect.”//**

**//“Opposition to godliness is atheism in profession and idolatry in practice. Atheism is so senseless and odious to mankind that it never had many professors.”//** Newtonbecame a Member of Parliament on 1689 and 1690 forCambridgeUniversity. In 1690, his health began to fail miserably. His illness was thought to be a nervous breakdown. In 1696, the government appointed Sir Isaac Newton to be Warden of the Mint. In 1701,Newtonyet again took another place in Parliament. Two years later, in 1703, he was elected President of the Royal Society. In 1727,Newtondied at age 84 as the greatest scientist ever. He was buried in Westminster Abbey. Sir Isaac Newton’s contributions to science were varied. His thoughts covered many scientific ideas after his time. He loved God and believed all of His word. Before his death he wrote **//“I have a fundamental belief in the Bible as the Word of God, written by men who were inspired. I study the Bible daily.”//** And that was Sir Isaac Newton’s Life, death, and beliefs.

** Melting Ice Lab **

** Intro: ** What everyone basically did was that we all grouped up and had 2 cups filled with different temperatures of water and saw how long it took for ice to melt in each of them. This experiment was supposed to tell us how surrounding temperatures affect rates at which water melts. We also measured the temperature as well.

** Problem: ** How does the temperature of the surroundings affect the rate at which ice melts?

** Hypothesis: ** The heat of the warmer solution will cause the ice to melt faster.

** Materials: ** thermometer, 2 cups about 200 mL each, 2 stirring rods, ice cubes, warm water, about 40-50 degrees Celsius of room temperature water.

** Procedures: **


 * 1) Read steps 1-8. Based on your own experience, predict which ice cube will melt faster.
 * 2) In your notebook, make a data table.
 * 3) Fill a cup halfway with warm water (about 40-50 degrees Celsius). Fill the second cup to the same level with room temperature water.
 * 4) Record the exact temperature of water in each cup.
 * 5) Obtain 2 ice cubes that are as close to the same size as possible.
 * 6) Place 1 piece of ice in each cup. Begin timing with a stopwatch. Gently stir each cup with a stirring rod until the ice melts.
 * 7) Observe both ice cubes carefully. At the moment 1 of the ice cubes is completely melted; record the time and temperature of the water in the cup.
 * 8) Wait for the second ice cube to melt. Record its melting time and water temperature.


 * Data/Observations: **
 * 10-31-11 || Beginning Temp. (Celsius) || Time to melt || Final Temp. (Celsius) ||
 * Cup 1 || 20 degrees Celsius || 6 minutes 39 seconds 21 milliseconds || 14 degrees Celsius ||
 * Cup 2 || 40 degrees Celsius || 1 minute 50 seconds 85 milliseconds || 23 degrees Celsius ||


 * 11-1-11 || Beginning Temp. (Celsius) || Time to Melt || Final Temp. (Celsius) ||
 * Cup 1 || 24.9 degrees Celsius || 300+ seconds || 12.9 degrees Celsius ||
 * Cup 2 || 42.3 degrees Celsius || 131 seconds || 24.9 degrees Celsius ||


 * 11-1-11 || Beginning Temp. (Celsius) || Time to Melt || Final Temp. (Celsius) ||
 * Cup 1 || 24.9 degrees Celsius || 300+ seconds || 12.9 degrees Celsius ||
 * Cup 2 || 42.3 degrees Celsius || 131 seconds || 24.9 degrees Celsius ||


 * Results: ** We had 4 trials in 2 days and the results on all 4 were completely different. My hypothesis was proven correct from these results from the hotter water melting the ice faster. Between the first 2 experiments the ice melted faster in the hot water by 5 minutes 08 seconds and 31 milliseconds.


 * Conclusion: ** From all of the experiments, results, and checking I learned how the temperature of something can affect something else. The results proved my hypothesis right as stated in ‘results’. My hypothesis was, ‘the heat in the solution will cause the ice to melt faster’.


 * Discussion: ** There a millions of ways I could’ve gone wrong in this experiment. Some of the possible ways I could’ve gone wrong is the way I stirred the water. I could’ve also poured too little or too much water into the cup and not have noticed.

media type="custom" key="11858982" Yesterday, on Jan. 11, 2012, we did a lab to see how long it would take for Alka-Seltzer to dissolve in hot, room temperature, and ice cold water. A chemical reaction is a chemical change. The evidence shown to tell when a chemical reaction is taking place is when we dropped the Alka-Seltzer in and it started to fizz and bubble. My original prediction on how long it would take to dissolve is that it would dissolve 5x faster in the hot water. We did 3 trials to see how long it would take, 1 trial for each temperature. In trial 1, we started with the room temperature. The temperature was 17.2 degrees and dissolved after 56 seconds. The second trial, we used the hot water.The temperature was 81.9 degrees and the Alka- Seltzer dissolved after 20 seconds. Finally, we used the ice water and we got a temperature of 2.4 degrees and a time of 2 minutes and 24.2 seconds. Again, i could see the chemical reaction taking place when it started to bubble, fizz, and dissolve. Based on my evidence, other solutions will dissolve quickly depending on temperature. It was evident that the purpose of the lab was solved when the Alka-Seltzure started to dissolve. This is my popplet of butane. It explains how butane is used in cigarette lighters and cooking gas. Butane was also found in 1944 by a Swedish chemist. Butane can have other uses in a blow torch. Also, some facts about butane are how it has 4 carbons and 10 hydrogen. Now, i could tell you more, but just look at the popplet! My hypothesis which stated that the solids would dissolve more easily was proven wrong. The liquids seemed to dissolve better after a few moments of stirring. The water was polar. The molecules between solid and liquid react differently, although the liquids dissolved better. I could tell when they were starting to dissolve when they were mixing very well or not at all. The water molecules mixed with the other molecules to create big or bigger compounds. Solubility is important form it being able to tell us what mixes and what doesn’t. media type="custom" key="16201690"This was a fotoable Danika and i did on the rocket lab.It explains the process and Newton's 3rd law of motion.We recorded our voices and explained it in step-by-step detail.Scratch Projectmedia type="custom" key="18019750"This is the Scratch that i worked on this week. Scratch is a computer generated cat that talks to famous history people. We created an interview with Sir Isaac Newton. I want people to see what we learned about Newton and his discoveries and accomplishments. It explains the life and accomplishments of Sir Isaac Newton.It explains his accomplishments, date of birth, and more. He was influenced my Aristotle, Galileo and Kepler.If i was to do another scratch, i would do a musical one because i love music. It interests me because I like to find out different things about computers.
