What is Science?.... Science is the study of mostly anything on earth and the far beyond or knowledge of any material completed by observation and experimentation overtime.

In the real world scientist..... Scientist's in the real world discover new things, even invent new things and solve puzzles of the world. When scientist goes through an exploration of a idea they have they use many tools to help them, like lab equipment and computers, but the biggest one is the scientific method, where scientists go through a process of steps to observe and experiment and go over their subject or idea over and over again until they have discovered something and come to a conclusion.

In science class we..... In our science class we do experiments or labs, and even look into technology, but what we really do is study a subject of anything and make tons of observations and come up with conclusions to support any ideas we have about our subject.

The purpose of this site is.... The purpose is to expand the learning of everything in science for anyone who wants to look into science or just learn something new in a science subject.

Lab Safety Poster

 This is my poster about LAB SAFETY. The point of the poster is to make people think and use lab safety before any labs. The reason I choose power point because its simple and the best way to present. The purpose of this poster is to get people learning about LAB SAFETY.

LION LIFE:

This is my LION LIFE poster assignment. The point for this assignment was to learn a little bit about me, or describe me. I used power point because it is easier to use and more similar to people. I saved it as a jpeg and uploaded it on the wikispace. Now the purpose of this was just to get to know me better.

Measurement Beginnings:

How did measurement start? Well it trully started in the 1400s B.C., when the Egyptians were around. The Egyptians developed the first weighing system. The tool was a simple balance with a pointer. Before they came up with the balance they had measurement in length, or to them it was an elbow to the tip of the middle finger. After the Egyptians came Lydia. In Lydia there measurement was for seeing how much money they needed to give or trade with each other. And that was already happening in 640 B.C. A little later something was happening in 200 B.C. China. China's very first emperor though was coming up with sets of standards for weight, length, and volume. What China is really none for though is finding the decimal notation, which people still use today. Next in the history of measurement goes to Central Europe. In 789 A.D. the emperor of Central Europe Charlemagne came up with a unit of weight and today we call it "Charlemagne's Pound." Now lets go a little bit back in time to England where the term acre had been created. An Acre is the common measurement of a area. Acre also meant though during those times was the amount of land that two oxen could plow in a day. Moving now though onto a later time in A.D. 1714 Germany. In Germany there was a man named Gabriel Fahrenheit invented the very first thermometer. Which shows the temperature of the air around you. Now last but not least in 1983 A.D. in France something was brewing in measurement. The International Bureau of Weights and Measures defined that a single set of units is the same everywhere, and also they said that a meter is the distance that light travels in a fraction of a second. That was the basic history of measurement, I'm not done here. I have also to say, why it's important to know about measurement. Why we should all know measurement is because if we didn't know how long, or how much there is in something we wont know the exact measurement. Plus too measurement helps in everyday life with like maybe a math problem, a chemistry lab in school, or measuring anything.



lab on properties of a liquid  Today in science class we had a viscosity lab. In the lab we used a fun little simulation to help us understand viscosity better. How the simulation help me learn something was that when you dropped a ball into a thicker substance with low temperature and it sinks slowly it has high viscosity. But if a container had heated up no matter what substance the ball would go down quicker. Another part of our lab was looking at particles and their motion on how they move. In a solid they are arranged in a tight, regular pattern and move very little. In a liquid they move past each other with ease, yet they're close together but not in a neat arrangement. Finally in gas they move rapidly and there are much larger spaces between them than liquids or solids. Now the last part of our lab was looking at the melting and boiling point of different substances. In a crystal substance the melting point is 0 and 100 is the melting point. Next there was a purple substance which had a melting point of 47 and a 143 for boiling point. And once again finally there was a green substance which had a 30 degree melting point and 121 of the boiling point. That was our lab today.

media type="custom" key="10921992" This is our Gas Laws lab. In this lab we used a simulation to understand those laws. The simulation was easy and quick to use. Some cool things we learned was when temperature increases volume and pressure will too. Then if the temperature decreases so does the volume and pressure. Why they do this is because everything is cooler so they slow down. And that was our little lab.

LAB REPORT: Introduction: In class today we had had a lab on melting ice. We looked at the different temperatures and times it takes for ice to melt. And made a data table to record our results.

Purpose: The purpose of this lab was to see how fast or how slow ice melts at different temperatures. The question also is, "how does temperature of the surroundings affect the rate at which ice melts?"

Hypothesis: My hypothesis was that the ice will melt in a warmer solution faster than room temperature water.

Materials: Thermometer, stopwatch, 2 cups, ice cubes, room temperature water and warm water.

Procedure: First make a data table. Second take a cup and fill it to the halfway point of the room temperature water and record the beginning temperature. Then put an ice cube in the water and record the time for how long it took for it to melt. Next record the final temperature of the water in the cup. Finally, do the same procedure for the other cup with the warmer water.

Observations: Some things I observed were interesting. Like for an example instead of the ice cube really melting it just dissolved in the water. Then when you pour the hotter water into one of the cups steam was on the side of the cup. And the different times were interesting too. Here is my data table:

(c) || Time to Melt (s) || Final Temperature (c) || Also in my observations the cups 3 and 4 were with a probe so we saw the biggest drops in temperature when the ice was melting. In cup 3 at room temperature water it started at 19 then dropped a degree to 18 degrees. In cup 4 at warmer water it went from 35 to 21 degrees.
 * || Beginning Temperature
 * Cup 1 || 21 degrees || 255 seconds || 15 degrees ||
 * Cup 2 || 41 degrees || 160 seconds || 30 degrees ||
 * Cup 3 || 19 degrees || 300 seconds || 13 degrees ||
 * Cup 4 || 35 degrees || 66 seconds || 33 degrees ||

Results: The results in what happened were the ice melted in the cups. They happened though in different times and temperatures though. And there was 4 trials through out the experiment one with a probe and the other not. We used for tools thermometer, stopwatch, different types of water, 2 cups, and ice cubes. What we were measuring was the temperature and time for how long it takes to melt ice cubes. The variables were the temperature and time of the experiment.

Conclusions: In my hypothesis, I was right because you can see in the different times and the warmer water melted faster with a 2 minute difference. My hypothesis was that ice will melt in a warmer solution faster than room temperature water. The cup that had the most change in the experiment was the warmer number 2 cup it had the most change because there was a difference in temperature with it, in the beginning temperature being at 41 degrees Celsius its ending with a temperature drop of ten degrees, leaving it at 30 degrees. And a side note as ice melts the thermal energy in the molecules let it overcome being a solid and turning it into a liquid. Besides that how you get the exact moment when the ice cubes melt is by seeing or watching the ice cube melt very carefully and seeing nothing solid left or dissolved in the water of the experiment.

Discussion: All possible errors we could have made were many. First in this experiment we could have not timed it right by starting the stopwatch to late or to early as we put the ice cube in. Second In the experiment we could have read our thermometer or probe wrong with the temperatures. Third we could have had a bigger ice cube than a usual size one. Those are just some things that would've gone wrong in this lab. How this experiment though could be relevant in everyday life is by getting a glass of something and putting ice cubes in it to drink.

Bohr Model:



In this lab we experimented with making a Bohr model and through it how to balance and stabilize an element. This simulation shows the shell rotations of the electrons and how the protons and neutrons interact with each other in the nucleus. This simulation really helped me understand the particles or properties of how elements are made up on the inside of them.



Properties of Metal Summary:

Look at the periodic table and you will see that most of the elements are metals. They are located to the  left of the zigzag line on the periodic table. There are different families of metals and some are called  alkali metals, alkaline earth metals, and transition metals. A mixture of metals is called an alloy. The  physical properties of metals are its hardness, shininess, malleability, and ductility. Some examples are  polished silver is an example of shininess, and a ductile and malleable example would be copper  sheeting and copper wire. Most metals are also good conductors because they transmit heat and  electricity easily. And, most metals show a wide range of chemical properties. Now even though there  is so much more we can learn about elements we do now that there are over 90 kinds of metals and we  will still continue to investigate the different metals in the world today.   <span style="background-color: #ffffff; display: block; font-family: arial,sans-serif; text-align: left;"> <span style="background-color: #ffffff; display: block; font-family: arial,sans-serif; text-align: left;"> <span style="background-color: #ffffff; display: block; font-family: arial,sans-serif; text-align: left;">Chemical Reaction Lab paper: <span style="background-color: #ffffff; display: block; font-family: arial,sans-serif; text-align: left;"> Purpose: The purpose of the lab was to look at, observe, and graph a chemical reaction of having a cup of water and adding alka-seltzer pill. Chemical Reaction: A chemical reaction is a process in which substances change into new substances with different properties. Or, another name for it is a chemical change.

Evidence: The evidence that determines a chemical reaction has occurred is the particles, atoms or ions, which are reactants, must physically come into contact with one another. Anything that increases the frequency of these encounters will increase the rate at which products are formed.

Prediction: Using hot water out of the tap, the rate of the reaction will be 5 times faster than at 0 degrees Celsius.

Number of trials: There were 3 trials in the lab.

Trial one: The first trial was with room temperature water. The starting temperature was at 17.3 degrees and ended at 17.2 degrees Celsius. And it took 64 seconds or a minute and 4 seconds to dissolve. When we added the pill it dissolved at a normal pace and spread out thoroughly with the color. It also started automatically right when it got in the water and bubbled a lot.

Trial two: The second trial was having to add hot water. The starting temperature was at 78.1 degrees and the ending temperature of the 2nd test was 80.4 degrees Celsius. The test of it lasted 20. In the experiment right as we added the pill it dissolved immediately and it almost looked like an explosion and the color change happened immediately.

Third trial: In the last experiment we added cold water and to make it cold we added ice cubes. The starting temperature was 1.6 degrees Celsius and the ending temperature was .6 degrees Celsius. All of the pill took 165 seconds to dissolve and was the longest trial. As we dropped the alka-Seltzer it stayed in tack for awhile, one by one the bubbles came up while dissolving the pill.

Evidence of reaction: There were different things that were evidence of a chemical reaction taken place in all three trials. First, there was a change in temperature each trial. Second, a color change happened in all three while the pills were dissolving. And third, there was gas production with oxygen bubbles floating to the top of the cups.

Summary Questions:

1. At a temperature of 10 degrees C., it would take 64 seconds for 1 Alka-Seltzer tablet to react with 8oz. of water.

2. If the temperature is doubled from 20 degrees C. to 40 degrees C, the times for the rate of reaction increases by approximately double it.

3. Using hot tap water, the rate was 10 times faster than at 0 degrees C.

It was evident that the purpose of the lab was met because in the lab we could look at, observe, the different reactions that happned.

Popplet: media type="custom" key="12370956" Popplet Summary:

<span style="background-color: white; font-family: Arial,sans-serif;">In class we were assigned to research a chemical compound to make a model on and a popplet. We had to make a popplet which was a new tool on the web we used and we had never used it before. Popplet wasn’t a very hard tool to use, because it was easy to move around on and to downloads pictures. I had no trouble at all making the popplet on Formic Acid it was easy, and a fun new tool I was able to use. We had to research four parts to the element its examples of the compounds, atomic structure, its type of bond, and history. One thing I learned from this activity is that Formic Acid is a covelant bond meaning that it shares its atoms. I found this activity to be a fun, and new exciting way to learn how to use a new tool.

Chemical Bonding Activity: <span style="background-color: white; font-family: Arial,sans-serif;">



Chemical Bond Activity Summary:

Yesterday in class we did an activity in class called "Chemical Bonding Activity." In the activity we had to make 16 different compounds using eight valence electrons each. I found this activity to be a fun but not the most exciting to be activity. It was very easy and direct but, sometimes the program had glitch and sensitivity problems. And, it was fun because we drew on a separate sheet of paper what the compound looked like, almost identical to the picture you see above. I learned from this activity of how to make a Lewis dot diagram or model of the chemical compounds. Through out all of the activity it was simple, direct, and easy to go through.

Conclusion:

In the beginning of our lab we had to make a hypothesis on which substances dissolves more easily: solids or liquids? My hypothesis was that liquids would dissolve more easily because they are already in a liquid state and should blend more easily. That was wrong, the real and true answer for the problem statement though is that neither solids or liquids dissolve faster or easier because it depends all on the solute some dissolve faster than others do. Whenever a solution forms, particles of the solute leave each other and become surrounded by particles of the solvent. All of this leads to how does the concepts of solubility become important in life as a scientist? Well, first the definition of solubility is the measure of how well a solute can dissolve in a solvent at a given temperature. But, how it is important in life is by it can be the difference between having really sweet lemonade or regular lemonade.

Newton's fotoabble

Scratch Project on Sir Isaac Newton media type="custom" key="18020694"

Scratch Reflection:

In class the last few days, we've been learning how to use the technology system of Scratch. We had to make a little game show with Isaac Newton and about him. I found this activity to be interesting but, also fun. It was a little difficult because it was a new program, there was glitches sometimes, and the instructions got confusing a little bit. What I would want people to see from my project is the cool light show in the program. If I was to create another one I would make an actual show game like wheel of fortune. The reason why it was fun was because when all of the project was finished it was good feeling that it looked great. I learned from this project of how to make a scratch of my own. But, throughout all of it was fun, direct, and easy to do.

History of the Universe's Solar System media type="custom" key="18623276"

In class we started a project about a timeline in history. It has been about the History of the Solar System. We made the timeline with a program on a website called Dipity. I found this activity to be interesting, yet hard. It was a very difficult program to use because of how slow you could make progress but, it was very straight forward. Something that shocked me though was seeing how many scientists tried to one up each other with each others research. And something I learned from all of it was that the solar system of the skies is called heliocentric system.
