Summary:
        When you are making a building you have to think about more things such as how you are going to impact the environment like the wildlife, air the water, trash, pollution, etc. A example of an environmental accord is to make sure is to make it so that in 7 years to make sure that there will be more recycle and composting so that there is less waste in landfills and incinerators by 25%. Another one is to make sure we  have 50% more shade for walkways by adding things like trees so that it will make you cooler to make sure that people do not use the air conditioning as much and waste energy or create more pollution. One more example is that in 7 years there will be at least 20% or more locally grown and organic foods served.

S&EP: SP2: Developing and using models:
The way that I used a model is that I had to make a small presentation about the environmental accords that I wanted to include in our environmental accords in our urban village. What we had to do was choose some environmental accords and we had to put them in the slide and decide how we are going to include it like how if you wanted to compost who is going to do it and how will it work in your space. An example is like how we want to make it so that there is more shaded walkway so that people use less energy for the air conditioning. We wanted to do this buy making paths with tree's for shade on both sides. The accord for this was to make sure that there 50% more shade for walkways so we wanted to add more trees.

XCC: Cause and effect:
When you throw away any of your trash for the landfills it will eventually decompose and become methane gas which is a pollutant. When you do simple things like when you turn the air conditioning on it will waste energy which we should be conserving. When we pour water down the drain or leave the water you are wasting the water that could be used for other purposes and we are wasting some of the little fresh water we have. When we do things like when we compost it make sure that we are being better for the environment and reusing our natural resources. When we turn the sink off when brushing our teeth it can help to save and conserve the little fresh water that we have on this earth.

Summary:
        To make bases, acidic or to make them neutral you have to add acids and if you want it neutral you might have to add some neutral also. To make acids, basic or neutral you have to add bases and if you want it neutral you might have to add some neutral. To make something neutral basic you add a base and to make something acidic you add a acid. Human impacts on the world are most of the time bad and there are ways that we can help to slow down global warming, pollution and save the environment. Some ways we can help is walking, biking and using public transportation, having more shade to use less air conditioning and saving energy, stop deforestation, etc.


S&EP: Conducting investigations
        Alien juice bar is a game where you test the pH of different liquids to see how acidic, basic or neutral something is. After you know what is acidic, basic and neutral you have to try to balance liquids to be basic, acidic or neutral for your costumers. This helps you to see how to make an acidic solution into a basic solution and the other way around. I found that to make an acid or a base into the opposite then you have to add the opposite. I learned about different things that are acids and bases like how window cleaner, cough medicine and toothpaste are bases and how coffee, tea and soda are all acids.


XCC: Cause and Effect:
        When people do daily tasks like drive your car to school or to work,drive to the store or driving at all can increase pollution and smog. When you walk, bike or use public transportation that makes it better for the environment and does not create as much pollution and smog. When you throw trash away that goes into the landfill it will eventually turn into methane and increases pollution and global warming. When you compost and when you think more about it before you throw your trash away we can help to prevent this. All of these things that humans do impact the environment and most of the time we do not have a good impact.

Summary:
        Any solution with a PH level of 7 is a solution that is neutral like water. When a solution is acidic it creates hydrogen ions and makes it lower on the PH scale like citric acid and sour candies. When a solution is a base it creates hydroxide ions and makes it higher on the PH scale like soap. To test if a solution is acidic or if it is basic you can put a piece of litmus paper and seeing if it turns a red or a blue color, if it turns red that means the solution is acidic and if it turns blue that means the solution is basic. Your pee is slightly acidic and see water is slightly basic but surprisingly is is safer to drink your own pee rather then drink sea water. When something is more concentrated it means that there is more acid or base dissolved into the solution and when it is diluted it is the opposite.

S&EP:SP3: Planning and carrying out investigations:
        I did an experiment to see how bases and acids can be identified by color by using cabbage juice, an acidic and a basic solution. What we had to do was take the neutral cabbage juice and put them into 12 different tester cups. Then we took the two solutions and made them more concentrated by adding more acid or base to the solution each drop that we added to each cup. We saw that when we had an acidic solution it turned from the basic purple to a light pink to a darker pink and closer and closer to red. When we added the basic solution it made it like a teal and dark green to more of a lime green color. We also compared the colors to their PH levels.

XCC: Structure and Function:
        When something is concentrated and it is very acidic it makes it great for doing things like removing rust from metal to make it more clean and look better. When something is concentrate and it is very basic it makes it good for cleaning laundry and to make it brighter like bleach. The bleach is very concentrated and is higher on the PH scale to make it so that it can easily remove the stains off of your white shirt. The rust removing solution is very concentrate and acidic to make it better remove all of the rust off of the metal where you do not want the rust. Neutral things like water are good so that we can drink it and stay hydrated without having it be acidic or basic.

Article blog/ Cheetahs

Summary:
        A cheetah is the fastest mammal and can run as fast as 60-70 mph but when it is chasing other animals and things for food it does not run that fast. Even though cheetahs are very fast they can not run for long and takes about half an hour to rest and to eat it's prey. This animal hunts in the day and has great eye sight for this and will bite into its preys neck to kill them for food. Cheetah's only weigh from 77-143 pounds and are about 6-8 and is considered a big cat. Cheetah's live for about 10-12 years, are carnivores and live in the grasslands. Cheetah's are endangered because of low food supply and more and we need to protect this species to make sure it does not become extinct.

S&EP:SP3: Planning and carrying out investigations:

                The authors of the national geographic, cheetah's article had to do lots of research to know all of the things about cheetah's in the article. They had to make sure that all of their facts were correct by doing investigations. National geographic had to plan out how they want to organize and how they want to format the site. They had to investigate live Cheetahs to see how they live and what their lifestyle is like in order to write accurate things about them. The authors must have had to have a long process and this must have taken lots of planning and investigations.

Weekly blog bonds.

https://upload.wikimedia.org/wikipedia/commons/thumb/3/38/Ionic_bonding.svg/2000px-Ionic_bonding.svg.png

Summary:
        Ionic bonds are when you have two atoms that are bonded like magnets and to make a ionic bond you need two atoms, one with a negative charge and one with a positive charge. Ionic bonds are formed between two metal and a non metal. When you have a covalent bond you have two different atoms that share electrons because of potential energy. Covalent bonds are with two non metals. Chemical reactions require two or more reactants to create a new product. The product/s have the same mass and atoms as the reactants just in a different order. There are different ways to know if a chemical reaction happened and a couple are fizzing and gas being released change in color and more.

S&EP:SP3: Planning and carrying out investigations:
       We had a worksheet that we had to fill out by investigating on a website and observing how the different kinds of bonds are formed and how they react with each other. For the convalescent  bonds it showed how they are attracted to each other and how the potential energy changes. For ionic bonds we found how they would want to stay with each other and were like magnets. We also observed and took notes with chemical reactions to see how much vinegar and how much baking soda you would need to make it so that it would not over flow in a 100 ml container. We found that it would take about 1/2 of a teaspoon of backing soda and 7 ml of vinegar along with 2 drops of laundry detergent.

XCC: Cause and Effect
        When you have two different reactants and you mix them together to create a chemical reaction it will causes the atoms or molecules to rearrange and create a different product. When there are different charges in atoms and they are attracted to each other then bond then it would make an ionic bond. When there are two atoms that get attracted to each other that causes a covalent bond. When there atoms that have lost electrons and have a positive charge they have cations because of their charge.. When there are atoms that have gained electrons and have a negative charge they have anions because of their charge.

Summary:
          A element is something that is made out of only one type of atom. Element's are things that can't be separated. There are over 100 different kinds of elements in the periodic table of elements such as things like gold and hydrogen. A pure substance is something that is made up of only one kind of  matter. Compounds are pure substances contain two ore more different types of atoms such as water. Mixtures are two more molecules that are not chemically combined and can be separated by physical means. An example of a mixture is iron fillings and sand by using a magnet to separate the two.

S&EP: SP3: Planning and carrying out investigations:
   I worked on play.lol  or an interactive game to find out different way that chemical reactions can happen and different signs of chemical reactions and what different reactions make different reactions make. In a chemical reaction you can mix different things to make different products. Some examples are mixing chlorine and mixing sodium to make table salt. You can also mix things with heat to make different products. Some different ways that you can know if there is a chemical reaction is things such as bubbling, extreme heat, change in color, consistency and more.

XCC: Cause and Effect:
          By causing a chemical reaction you mix two ingredients to make a different product. The reason that we have things like simple table salt is because sodium and chlorine got mixed and when they mixed the product was table salt. The reason that we have carbon dioxide is because oxygen and carbon met to make carbon dioxide. The reason why we have water is because of hydrogen and oxygen meeting to make water. The reason why we have some of the simple things that we do like water, salt and carbon dioxide is because of chemical reasons or two different things meeting to make something new.
