====**Below __there is the paragraph of the topic "__Science__." This explains the concepts we learned in class about our time with__ science __and how we use science. This is so that we can spread to the world of what we learned in class and helps teaches others about it. :__**====

__ **What is Science?** __ Science is anything. Explain how your body was built, how can we breath, what kinds of stones are there, and more! God made all these things for us to discover and awe at. But scientist cannot discover ALL of science. There are so many subjects on science that they haven't discovered yet. This means science is a mystery, but with __great__ knowledge is important in science. We are glad to have our science books since we can learn so much in it. __ **In the real world scientist...** __ __Help__ __improve__ our world with great advances in discovery. Without scientist, we would question so many things and not know, therefore god’s wonders are hidden from us. Isaac Newton and Charles Darwin are great examples of past scientist. They may have passed __away__, but their observations still lives on to this very day. Improvements from scientist helped a lot. __Phones__ and others are a great example. Every week, they come up with new ideas like __touch__ screens and data plan. They might even write the text book that we have! Sharing their observations is a wonderful thing for the world because maybe it will do good use. There are many types of scientist, engineers, philosophers and much more. Each one has a specific role. Some __make__ __phones__, some try to discover new __phones__, and some maybe fix __phones__. __ **In science class we...** __ Discover like scientist and we learn and write observations as notes. The more we learn the more knowledge we __earn__. Some love science, some don't. It doesn't matter as long as you are willing to learn. We've also done labs and reports and we learned something that we didn't know from that project. Some of us will awe at the amazing things that science can do. __ **The purpose of this site is…** __ So we can share our own knowledge with others. Expanding our knowledge is a great thing to do if others don’t know about this. Everyone has their own opinions and therefore we should share them. Just like real scientist, they gather up their basic information and share it with the others. Some might think it’s boring and some might get into it. Who knows you might learn something every day

__**Here is my Poster for Lab Safety. It talks about being safe while doing lab and following the rules. :)**__

__**Here is my Poster of "The Secret life of a Lion": This talks about my goals of being in ECS**__

__**This paragraph talks about the history of measurements and about how each different countries have there own different ways of measurements. I know it looks long :P :**__
If you think about a person, they have different emotions character and opinions. Everyone cannot be the same. Just like the countries who came up with different measuring tools. Each country is different with there measuring because thats how they think of it. Like the Egyptians. How did they built such enormous structures such as the pyramids and the sphinx? They discovered a weighing instrument of weighing things they need to use such as the bricks to make the structures. They also measured with their arms too. How? Look at your arm. __Start__ from your elbow and end with your middle finger. You've just learned how to measure by cubit. A cubit is 15 in. of your arm. That is how they can make bricks and things. Without the egyptians __learning__ about cubit, they couldn't built all the monuments and structures. In the Middle East, they always use __coins__ as __money__, but how would you measure all that __money__ when or if you __become wealthy__!? A country in the Middle east, Lydia, has made a instrument that helps so much with __money__. that it helps paying for depts and bills wuicker and much easier. In America we have paper __dollars__ so we dont need them, but in some other countries, they need it and billing takes so much easier. We always use math everyday but in the past, we never had FORMULAS to solve so solving takes much longer and takes up the room of your writing board. The chinesse have development formulas. The Emporor of china(Shih Huang Ti) has put standards on weird, lengh and volume. They where the first to create scientific notation and the numbers based on 10 digits. Without them, we wouldnt be able to solve the quick and easy way. we had to do the long way. When we have a piece of land but don't know the area(area inside of the land) of it, then where in trouble. Luckily in England they have land called acres. In England, acres used to stand for "area". They have created measurements for area so we can solve and know our area of land. Have we ever tried to weigh things but can't figure out how much lb. it is(pounds). In Central Europe, Charlemagne created "pound". He used the standard unit of weight and translated it into pound. It is usually called mass. If he had never discovered pound, we wont know how many pounds do we weigh and to weigh other things to find out its pound. Have you ever wanted to know how mandy degrees it is outside. It can either be hot or cold. That is why Germany made the THERMOMETER. A thermometer is a device with mecury in it that raises when its hot and lowers when its cold.Without germany making the thermometer, we wont know the temperature outside and if we wear the wrong thing, we can either get a heat stroke or freeze to death. That is how to news people figure out the temperature and they tell it to everyone so everyone will know. We have more gadgets now to easily tell what the temperature is outside but sometimes we still use the thermometer. Space is the mystery of all subjects but some say it is impossible to caculate light travel. In France, the International Bureau of Weights and Measures did. They also figured out about using weight and measurement EVERYWHERE. They had figured out the caculation of distance light tracel in a fraction of a second. If they hadnt done the caculation, we would never knew about space and when we send our space ships toward space, we wont know how far we have to go and sometimes die. From reading this you may think that this is ALL the countries that figured out each different measurement of but they are not! There are more countries that come up with different types of measurments that don't even relate to math! Each person is different with there own ways and come up with different ideas of solving. This works for eveyr country becuase every country has there own ways of culture and things. Asian weddings are different then Germen weddings. American foods are different from French food. Everything is differnet from everyone and that relates to measurments to. :)

====__**This is an expierement that i've done in science class. This talks about the the balls containing less or more viscosity. Viscosity is the ressistance of liquid to flow. I've tested this expierement on which one falls slower and faster. 2 balls are dropped into heated or cooled substances of water and I have to keep a record of which one falls slower.**__====

__**Ice Lab:**__
==== __**Lab Reflection**__: __**This talks about my expierence in the lab and what I have done. It is mostly about an ice cube melting in warmer temperature. As you read along you will understand. Enjoy :)**__ ====

**__Intro:__** **The purpose of this lab is to find out if an ice cube melts in warmer water. We had 2 cups filled with cold and warm water. We put 2 ice cubes in it to see if the wamer one melted faster. We had to also find the temperature of the water and compare it with the other cup. If one of the cups has a higher temperature, the cup filled with water is the one that made the ice melted the fastest.**

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

__**Hypothesis**__: **The cup with the warmer water will melt the ice quicker.** **__Materials__**: __** Procedures: **__
 * **Thermometer**
 * **stopwatch or timer**
 * **2 plastic cups, about 200 mL each**
 * **2 stirring rods, preferably plastic**
 * **ice cubes, about 2 cm. on each side**
 * **warm water, abour 40 degrees C - 45 degrees C**
 * **water at room temperature**
 * **Read steps 1-8. Based on your own experience, predict which ice cube will melt faster.**
 * **In your notebook, make a data table like the once below**
 * **Fill a cup halfway with warm water(about 40 degrees C to 45 degrees). Fill a 2nd cup to the same depth with water at room temperature.**
 * **Record the exact temperature of the water in each cup**
 * **Obtain 2 ice cubes that are as close to the same size possible**
 * **Place one piece of ice in eahc cup, begin timing with a stopwatch. Gently stir each cup with a stirring rod until the ice cubes melt**
 * **Observe both ice cubes carefully. At the moment one of the ice cubes is completly melted, record the time and the temperature of the water in the cup.**
 * **Wait for the 2nd ice cube to melt. Record its melting time and the water temperature.**


 * || Beginning temp. || Time to melt || Final Temperature ||
 * Cup 1 || 24 degrees C || 4:05 4 mins 39 sec. || 16 degrees C ||
 * Cup 2 || 42 degrees C || 2:10 seconds || 30 degrees C ||


 * || Beginning temp. || Time to melt || Final Temperature ||
 * Cup 3 || 21.1 degrees C || 300+seconds || 9.6 degrees C ||
 * Cup 4 || 41 degrees C || 184 seconds || 22.6 degrees C ||


 * __Results__: In the results, 4 trials were done in the lab. We used thermometers and digital probes for our scientific instruments. We where trying to measure the temperature vs. the time. In cup 1, the temperature was 24 degrees C in the beginning and the time is 4:05 4 minutes and 39 secs. In cup 2, the beginning temperature is 42 degrees C and the time was 2:10 seconds. In cup 3, the beginning temperature is 21.1 degrees C and the time is 300+seconds. Lastly in cup 4, the beginning temperature is 41 degrees C and the time is 184 seconds. It tells everything on the data table on the top. **
 * __Conclution__: In conclusion, the lab was very fun. My hypothesis which is "The cup with the warmer water will melt the ice quicker." is correct. The warmer the temperature, the quicker the ice melts. My hypothesis really relates because it is most obvious the warmer the temperature is, the quicker the ice melts but it depends on the size of the ice. If the ice is big, it melts slower, if the ice is small it melts faster. My hypothesis did not explain that. **
 * __Discussion__: I have noticed that we don't get the same results as other people so we might be wrong on some things. Also, the ice are not the same size. We could've gotten an ice tray and filled it with water, freeze it, and then we all get the same equal amount of ice. This will likely get the same results as other groups. The equipment sometimes glitches and probably collect wrong data and start all over again. We also have to time with stop watches and sometimes we start to late or to early and collect the wrong data time. Some of us question"Why do we have to do this experiment?" This helps us in life that do we not understand how this works. When we drink water, we wonder, how long does it take for the ice cubes to melt? Here you go, this is your answer to find out. **

===__This Bohr model is Boron. We are learning about elements in a periodic table and how they look like in a model. This is how you make one. On the periodic table you have to figure out how many electrons, protons, and neutrons it needs. Boron's atomic numberr is 5.__===

__**This wordle tells all the characteristics that an element has :]**__


**__Metals __** Metals are found on the left side of the periodic table. The properties of metals that scientists mostly classify on are hardness, shininess, malleability, and ductility. Also, metals show chemical properties like reactivity and corrosion. Examples of metals are alkali metals, alkaline earth metals, and transition metals. They are organized by reactivity as you move from left to right on the periodic table. In conclusion, since metal is an element, metal is mostly everything we use in life. Cell phones, T.V, laptops, and others are everything we use in life. We rely on on metals in life so think about how money gets its copper color and how mercury is used in thermometer which is a liquid. media type="custom" key="11858962" 

====__**Observations from lab: up there ↑ **__====

The purpose of this lab is to find the temperature and the time of the tablet to disolve in 3 types of water or lets just say, see the evidence of what a chemical reaction looks like. The 3 types of water we where recording observations to are Ice cold water, room temperature water, and hot water. A chemical reaction is a process that leads to transformation on a chemical substance to another. To find out the evidence for a chemical reaction to take place, You could look at the color change if any color changes. Precipitation which is when 2 solutions mix with another to form a mix. Changes in temperature is wehn it gets hot or it gets cold. You can tell if its hot if the water could be boiling of steaming. One last one is changes in properties which is like bread. The bread is soft dough and when put into an oven, it turns into a nice golden crunchy bread.

My original prediction for what would happen is that when the tablet is placed into regular water, it will dislove slowley. Then when i put the tablet into the hot water. It will triple the time it disolves. The trials done in this lab to get the purpose are three. One is to record data for the regular warm water. Second is to record the data for the hot water. Last one is to record observation for the ice water. In trial 1, My group was to take 8 ounces(1 cup) of warm water and place the tablet in the water and record the time it disloved and the temperature. The temperature 17.1 degrees C and the time was 67. The second trial was to take hot water and place the tablet in and record the time and temperature. The 3rd trial was to take cold water and place the tablet in and record the time and temperature. During these trials, the evidence for the chemical reaction that i saw was the color change. When the tablet was disolving, the tablet started shrinking and the water started turning bright orange and bubbly. Also i noticed the scent of orange when it was disolving. Although it smelled like orange fanta, we couldn't drink it :(.

** Hi there! We where supposed to watch a video in class about our assigned expierment. I had expieremnt 3 so Enjoy :) **
For this experiment, these are the items we need: a Ziploc bag, paper towels, ¼ cup of baking soda, ½ cup of vinegar, and ½ cup of water. For the experiment, you put baking soda on the paper towel and then fold it up like an envelope. In the Ziploc bag, pour water and vinegar in. Then, you place the baking soda In the Ziploc bag. The bag will then grow bigger and eventually, explode. This is a sign of a chemical reaction taking place. The vinegar and baking soda are mostly the common items that help the bag to explode. For me, I would love to try this experiment at home. I’d love to see the chemical reaction take place and watch it explode (//which is the fun part//). Plus if you add the full amount of vinegar, water and baking soda, the bag will probably grow bigger and make a bigger explosion.

**This is a Popplet for my compound. Enjoy :)**

**Summary for Compound:**
**In class, we where assigned a compound to do and create a popplet of that compound. We where supposed to research facts about the compound and place it on the popplet. Later on, we will make a model of our compound. The popplet is actually better than bubble.us because on bubble.us we couldn't upload pictures and plus it was a little more confusing. This has actually been interesting and confusing at the same time. First of all the compound that i was assigned to is rather confusing to me because it has confusing signs to follow in the model. Although it was confusing, it was preety fun. I would love to try something else since we've done this in the past years.**


 * Here is what we have done in class. We where supposed to be solving some compound equations. :**

Expierment on solubility
 * Summary:**
 * In class, we where assigned to solve compound equations and how it went together. Their are empty boxes as you see, and in the empty boxes, you must place the correct letter of the element in the box. If it is wrong, it goes back, if its right it stays their and shows its covalent bonding with others.**
 * Hypothesis: My hypothesis was that the solids will dissolve faster than the liquids because to me, the water is polar so things will mix into it better with nonpolar substances. **

 * <span style="font-family: Arial,sans-serif; font-size: 7pt;">Results: In the lab, we have done 1 trial for each substance and their where 9 substances. What I noticed, when I put the substance in the liquid, is that when they enter the water, some dissolve and some didn’t. One of them has been saturated because they raised to the surface. When they didn’t dissolve, it means they are non soluble, and if they dissolve, they are soluble. To prove that they are soluble, you can take the beaker and look closely and the water to see if the substance rises to top sinks to the bottom. We had to do this to each substance to determine if each one was soluble or non soluble. Something that I was confused on was that some of the substances didn’t dissolve. We had to stir some more and look closer to see if it was soluble or non soluble. Some of them where actually obvious because we use these supplies when we are cooking so we already know some of them might be soluble or non soluble. **
 * Conclusion**
 * Our class has done a lab to see what substances are soluble or non soluble. The ingredients where salt, sugar, vinegar, rubbing alcohol, pepper, powdered chalk, baking soda, corn starch, and vegetable oil. My hypothesis for this lab was that solids will dissolve more easily in water but it was wrong. This is because that neither solids nor liquids can dissolve in water because it depends on what they put into that type of substance. In the lab, some liquids and some solids dissolved and we didn’t know which one dissolves easier. Although, some of them like salt and pepper are either saturated or a suspension.**

media type="custom" key="18227532" This is the reflection of the Scratch project. This Scratch project shows the cat Scratch interviewing the famous philosopher Isaac Newton. Newton then tells Scratch about his birth, who influenced him, and what his inventions where. This will help you understand Isaac Newton and what he does. I would use Scratch because it is a good software to use and it is a software that is perfect for animation slideshows. I would do another project for school on this software because it is mostly easy to use. The problem i find with this is that you have to download this and it takes a while but it is mostly worth it. To me, i would use this again. It is a great software and plus it has a very awesome website that you can share your collection and watch others.
 * This is a picture of the rocket lab that we have done. We put alkazezer tablet into the rocket with different ml of water to see if it shoots farther or higher. It does work unless you put it in a position of shooting up, but if it is on the ground, it will go very little distance. The pressure of the alkazezer causes the rocket cap to shoot and make the rocket fly.**

media type="custom" key="18606924" Reflection: This is a Dipity. Dipity is a webstie where you can make your timeline. You can put specific time and dates on here and then save it. The thing i do not like is that it is slow.

Reflection: This is called the Bio cube. On the Bio cube, you can choose a character you will like to do and put some information on him. It is a great way to study about a person. You can save it and open it always on your computer. It is an O.K tool because it might get lost in the computer if you don't save and then you have to start all over. In this, Bio cube, I did Nicolaus Copernicus. He was an astronomer that wrote famous stories about Optics. His work is then used as presentations for other scientists to use. He lived for a very long time working on his work. Unfourtunatly he died of a stroke.
