**What is Science?**

**science is.... the explanation of natural events explained through complex steps. photosynthesis has many steps explaining how carbon dioxide is converted to oxygen.**


 * in the real world scientists..... research and dicover new things about the world and the space around around it. **
 * in science class we.... perform expierenments multiple times to come out with different outcomes .**
 * the purpose of this site.... is to expand on our learning and teaches others about what we know. **

My Lab Safety Poster: this is my lab safety poster. this poster explains how to be safe in a lab and what to do if something goes wrong. the tool i used to make this was my hands, I handrew this because i felt it showed how random and creative I can be. I hope you learn from my poster and my wiki...



My Secret Life as a Lion this is my secret life of a lion poster. this poster explains a little bit about me, what i like to do outside of school and the sort of things i want to be when i grow up :D

The history of Measurements Measurements have existed as early as 1400 bc in the time of the egyptians. the egyptians made the first weight instrument which was just a balance and a pointer. they measured in cubics, which was the distance from the middle finger and the elbow. in 640 BC in the middle east, lydia merchants used measurments to ensure that they had the correct amount of gold and silver and they also checked the purities of the metals. the lydians minted the first coin and measured in talents and minas, which was 25 kilograms and 500 grams. 200 BC shih huang ti the first emperor set the satndards of weight in length,weight, and volume. the chinese were the first to use decimals and a number system with only ten digits. Charlemagne was the emperor of central europe set the unit of length, karlspfund which traslated means charlemagnes pound, 789 AD. 700 AD in england when Ethelbert II made the term acre which was the measurment of how much two oxen could plow in one day. 1714 gabriel Fahrenheit invented the thermometer which measured temperature his name was used as a measurment of temperature. lastly in 1983, France the international bureau of weight and measurment defined a single set of units that was the same everywher. they also made a meter that defines the speed of light travels in a second.

Reflection on the Viscosity Lab what i learned... this lab was easy and fun to use, what i learned was that depending on the temperature and type of lquid things will sink faster or slower. for example honey at 20C will sink a lot slower than water or ethanol at the exact same temperature. also if you increased the temperature of the honey to 40C it will sink relitivly faster than it would at a lower temperature. so if you lower the temperature of the honey to about 10C the ball will sink at an alarmingly slow rate.

GaSeS AnD PrOpErTiEs LaB we learned about gases and their properties in this simulation... i learned that if you increase the temperature the gas molecules will speed up and the pressure will also increase and eventually the container will burst open and the molecules will fly out. for example when you have a hot air balloon and when you add heat the air molecules will expand and inflate the balloon and eventually it will lift off the ground and you will be in the air...

ICE LAB in this lab we expieremented with ice and its melting points. we had four different expierements in this lab each with different variables. two of the expierements had regular, room temperature water in the beakers. the other two expierements had hot water for overall different results.

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

hypothesis: the lower the temperature the slower the ice will melt, and the higher the temperature the faster the ice will melt.

Materials. 1. thermometer 2. 2 plastic cups, about 200mL each 3. 2 stirring rods, preferably plastic 4. ice cubes, 2 cm on each side 5. warm water <span style="color: #0000ff; font-family: Impact,Charcoal,sans-serif;">6. room temperature water <span style="color: #0000ff; font-family: Impact,Charcoal,sans-serif;">7. stop watch or timer

<span style="color: #0000ff; font-family: Impact,Charcoal,sans-serif;">Procedure: <span style="color: #0000ff; font-family: Impact,Charcoal,sans-serif;">1. make a table on a peice of paper or in a notebook <span style="color: #0000ff; font-family: Impact,Charcoal,sans-serif;">2.fill a cup halfway with warm water (40C to 45C) fill the second cup the same depth with room temperature water <span style="color: #0000ff; font-family: Impact,Charcoal,sans-serif;">3. record the exact temperature of the water in both cups <span style="color: #0000ff; font-family: Impact,Charcoal,sans-serif;">4. try to get two ice cubes that are about the same size <span style="color: #0000ff; font-family: Impact,Charcoal,sans-serif;">5. place one ice cube in each cup, begin the stop watch. gently stir till ce cube melts <span style="color: #0000ff; font-family: Impact,Charcoal,sans-serif;">6. observe both ice cubes carfully, the moment when the ice is completly melted record the time and temperature of the water in each cup <span style="color: #0000ff; font-family: Impact,Charcoal,sans-serif;">7. wait for second ice cube to melt and record the temperature of the water and the melting time.

<span style="color: #0000ff; font-family: Impact,Charcoal,sans-serif;">Data


 * Cups || Beginning temp || Time to melt || Final temp ||
 * Cup 1 || 23 C || 4:39 minutes || 15 C ||
 * Cup 2 || 42 C || 1:41 minutes || 30 C ||
 * Cup 3 || 18.8 C || 3 minutes || 13.7 C ||
 * Cup4 || 18.4 C || 2:07 minutes || 26 C ||

<span style="color: #0000ff; font-family: Impact,Charcoal,sans-serif;">observations: <span style="color: #0000ff; font-family: Impact,Charcoal,sans-serif;">the first two cups had a signifigently higher temperature than the third and fourth beakers. the times to melt varied in length due to the heat of the water in the beakers. the final temperature of the first cup was half of the temperature of the second cup. the third cup only dropped about five degrees, but as for the forth cup oddly the temperature rose about 8 degrees.

<span style="color: #0000ff; font-family: Impact,Charcoal,sans-serif;">Analysis <span style="color: #0000ff; font-family: Impact,Charcoal,sans-serif;">each of the temperatures begging and final were all around or below 12 degrees in range. also each of the time of melting are between 1 minute and 5 minutes. cups one and two begging temperature about 20 degrees apart while as the third and fourth cups the temperatures were only separated be .4 degrees.

<span style="color: #0000ff; font-family: Impact,Charcoal,sans-serif;">Results:

<span style="color: #0000ff; font-family: Impact,Charcoal,sans-serif;">at the beggining of the expierement we had all the materials ready to test the expierements and get our results. the first two cups were simple expierements and took longer than the third and fourth expierements. the room temperature cup of ice took over four minutes to completely melt. the second cups with the heated water only took a little under two minutes to completely melt. when we tested the third and fourth cups we had differnt equipment. we had an alcohol thermometer and a digital gragh to measure outcome with more prescion. the third cup took exactly three minutes to melt with room temperature, the fouth cup took two minutes and seven seconds to melt with the heated water. the overall thing that happened was the same expierements except with different equipment and different results.

<span style="color: #0000ff; font-family: Impact,Charcoal,sans-serif;">conclusion:

<span style="color: #0000ff; font-family: Impact,Charcoal,sans-serif;">I learned a lot of differnt things from performing this lab. I learned that you can get tons of completly differnt results when doing the same expierements over and over again, you probobly wont get the same answer more than two or three times depending on if you do the expierement right each time. I found out that temperature will ultimatly affect the time ice melts and that the ice will affect the temperature of things in its surroundings. the expierement proved that ice will melt depending on variables used in the process to spped it up or slow it down. I found my hypothesis to be correct because I said the lower the temperature the slower it will melt and the higher the temperature the faster it wil melt, clearly by looking at the data table the heated water melted the ice faster than the room temperature water.

<span style="color: #0000ff; font-family: Impact,Charcoal,sans-serif;">Disscusion:

<span style="color: #0000ff; font-family: Impact,Charcoal,sans-serif;">there were many sources that allowed errors to slip in. the size of the ice cube could affect the melting time and the outcome of the expierement. the ice cubes were also sitting at room temperature for a short amount of time, giving them time to melt again affecting the outcome and the melting time. another thing that couldve affected the expierement was the improper use of equipment. we couldve put the thermometer in too soon or too late getting a wrong reading of the temperature. we couldve done the same thing with the probes. mainly human errors like if someone forgot to watch the ice melt that would affect the time and the whole expierement.

<span style="color: #0000ff; font-family: Impact,Charcoal,sans-serif;"> This is a bohr model of boron. boron has five proton atoms and five neutron atoms. it also has five electrons. the purpose of this model was to let us understand how the structures of molecules look and what is contained inside them. we did this lab because we are studying the periodic table and it shows how the elements are made and stuctured

Properties of metal Metals are the must abundant thing on the periodic table. Metals are found on the left of the dark zigzag line with the most reactive in group one. to the right of the zigzag line are metalloids and nonmetals. each section of the periodic table is called a period, group or family. there are many types of metal: alkali metals, alkaline earth metals, transition metals and metals mixed in groups. metals have high melting points, they are shiny, hard, and their ductility. those are the properties used to identify metals. there are over 100 elements on the periodic table. the last known number was 118.there are approximately 95 metals on the periodic table. All metals are similar in many ways for example they are all hard, excluding the fact that mercury is liquid at room temperature.

the purpose of this lab was to examine chemical reactions...... a chemical reaction is simply just a chemical change. there

ia a lot of evidence to prove chemical changes. bubbling, color change, temperature change, and explosions all of

evidence of chemical changes. in this lab we performed a total of three trials.

in every trial there was evidence for chemical change. in the every trial the tablet bubbled until it was all gone. the main

difference between trials was that the three trials the time of the tablet disolving varied with the trials temperature. the

coldest temperature took the longest, the room temperature took a moderatly normal time, and the hottest trial took the

quickest my original hypothesis was that the tablet would disolve 3.5 times faster than that at 0 degrees celcius.


 * Room temperature (trial 1) || Cold water (trial 2) || Hot water (trial 3) ||
 * Starting Temp. 16.5C ||  || Starting temp. 69.7C ||
 * Temp after trial. 18C || Temp after trial .8C || Temp after trial 43C ||
 * Time. 1:11 minutes || Time. 3:28 minutes || Time. 22.5 seconds ||

this is my popplet... this popplet tells about methyl aldehyde. methyl aldehyde is a chemical compound with the equation of CH2O. it is a covalent bond. this compound has very diverse properties and is a a very volatile liquid. it is a colorless compound and its also moblie. this molecule has a double bond with an oxygen atom. it also has two single bonds with two hydrogen atoms.

Conclusion In some ways my hypothesis was correct, and in others it wasn’t. at first I had put that neither would dissolve faster, then I changed it to liquids because I thought that since they are in the same state of matter they would mix better than a solid would. Some solids dissolved better than the liquids and some liquids dissolved better than some solids. Overall I thought and saw that solids dissolved better than the liquids but it seemed to be equal. Water is a polar compound, when another substance is put in water the polar molecules are attracted to other polar or semi-polar molecules. Molecules break up into separate elements and then are surrounded by water molecules. The way you can tell when the solute is completely dissolved is when there is nothing left of the solute. Possible sources of errors in this lab was the fact that we might have not stirred the solution or put too much of the solute in the solvent. Another source of error in this lab was when we thought it was dissolved when it wasn’t so a lack of stirring or a misconception of if it was soluble or non-soluble.

Scratch: media type="custom" key="18018196" the other day we did a project in class called scratch. scratch is a digital animation tool that is meant for learning purposes. scratch was difficult at first because we had to follow a very specific set of instructions to make it work right. it involved a lot of clicking and dragging to attach speech, sound, control, and looks boxes for the dialogue and actions by the sprites. sprites are the characters that are involved and are performing actions in the set stage. this project was harder than others beca use it took longer and it got confusing at times but it was fun to problem solve and watch the final product with everything finished.

SCRATCH ADVENTURES!!! scratch is an online animation where you can make games and learning activities. we created a scratch about isaac newton. i wanted people to see what we learned about in class. we played around in scratch and i found a game call "nazi zombies 5" it was a scrastch version of call of duty nazi zombies and it was the coolest science class because of it. if i recreated it i would make it bigger and better than a regular scratch zombie game. this interested me becuase i love zombies, call of duyt, and 1st person shooters.

<span style="color: #008000; font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif;">BIO CUBE:
====<span style="color: #008000; font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif;">today we did a bio cube. a bio cube is an informational tool where you type in information about a person or object. all the different sides have a different topic or section about that person or object. it tells about the history and things the person overcame and accomplished through their life. or the history and significance of an object and the impact it has had on our daily life. i did my bio cube on Galileo. Galileo was a scientist who invented the telescope and he sold them to sailors and merchants. he also over came blindness at the age of 72 and he had to have his secretary do his work for him. he was born in 1564 and died in 1642. ====
