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.

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.
