Reefs Affected By Climate Change And Human Activity Article 4/30/17

Summary:Coral Reefs are starting to die out. This is due to pollution, too many fish being taken and global warming. Dr Fio Micheli is observing the effects of global warming/climate change and its effects on the Reefs. She observes the acidity levels of the ocean. 30% of carbon dioxide from human activity dissolves in ocean lakes and river makes the organisms have trouble growing their shells. Healthy reefs have no acidity and many schools of fish and unhealthy reef has no schools of fish and a high acidity level with algae growing in.

SP7: Engaging in argument from evidence: Many Marine Biologists care about  the enoviorment and Dr. Micheli's hardest part of her job is trying to get people to understand that the coral reefs are at risk and in need of help becuase its not just global warming affecting the reef its pollution and overfishing.  And many reefs are starting to have high acidity levels and are starting to have algae growing in which draws away fish which is a sign of a bad coral ree.f

Different Types Of Bonds 4/7/17

Summary: Ionic bonds are when 2 atoms bond together.  To bond one of the 2 atoms has to have a positive charge and the other has to have an negative charge. A covalent bonds is when 2 atoms share the same electrons for potential energy. Covalent bonds happen between 2 non metals. Chemical Reactions need 2 or more atoms to have a different outcome. To know if a chemical reaction is happening you need to see if there is visible gas, bubbling around the surface, fizzing, the temperature of the substance either gets very hot or goes down to very cold, and lastly color changing. The reactants still have the same mass and atoms they just get re arranged.

SP3: Planning and carrying out investigations: We did a lab to create a chemical reaction. Our reactants were baking soda,vinegar and laundry detergent. And our reactants had to yield our product... Sodium Bicarbonate. Our goal was to dry and put different amount of baking soda and vinegar into our test tube to see how much of baking soda and vinegar it would take to reach the top of the test tube(100 ml) without overflowing. (the amount of laundry detergent has to be the same the whole time - 2 drop of laundry detergent). And we knew it was a chemical change because we saw lots of bubbling and fizzing. The exact result to get to the top without overflowing was 1/2 of a teaspoon of  baking soda, 7 ml of vinegar , and 2 drops of laundry detergent.

XCC: Cause & Effect: When you have 2 or more reactants it causes those 2 reactants to rearrange their atoms to create something new. Like our baking soda, vinegar,and laundry detergent experiment all those reactants came together to rearrange their atoms to create Sodium Bicarbonate. When there are 2 atoms they get connected because they are attracted by each others atoms and bond for a chance of potential energy. If your atom has a negative charge it is called a cation. This happens when electrons get added giving the atom an negative charge. If electrons are lost then the atom has a positive charge which makes it a anion.So if a atom is positive its a anion. If it has a negative charge then its a cation.

Chemical Reactions 4/2/17

Summary:
A chemical reaction is a process in which one set of substances called reactants is converted to a new set of substances called products.
To know when a chemical reaction is happening you should probably look for these signs in the mixture you created. Either visible gas, bubbling around the surface, fizzing, the temperature of the substance either gets very hot or goes down to very cold, and lastly color changing. The Reactants are what you mix to get the product. And the reactants yield the products. And obviously the products are the outcome of the reactants.

S&EP: SP3: Planning and carrying out investigations: I played an interactive game called on play.lol and we basically had to figure out how one reaction causes another. And this was also supposed to show us how the different signs of a chemical reaction look like. Fizzing,bubbling,change in temperature or color, and gas starts to come out of the product. Dissolving is not a chemical change its is a physical change. Lets say its salt that dissolved. I am sure there is some way to change salt back to its normal solid was because dissolving it didn't change it.

XCC: Cause & Effect: When two different reactants are mixed together they create a product. Like if we put two hydrogen and one oxygen together it gives us water. One nitrogen, four hydrogen, and one chlorine. This gives us NH4Cl which is Ammonium chloride. Different things(reactants) combined create(yield) other things (products).  So whatever you put together always has another out come. Like Sodium and Chloride make NaCl (Sodium Chloride// Table Salt).
