Deeper Learning Dive: Acidification of the Ocean


The information from this video is credible, because they use excerpts based on information received from Dr. Carles Pelejero, who studies "deep sea sediments and corals as archives of changes in the past, use systems to monitor the present, and run manipulative experiments in aquaria to simulate the future." (Pelejero, Carles Pelejer, and Biogeochemistry, Research Group on Marine Biogeochemistry and Global Change. "Carles Pelejero." Home. © 2011-17 RESEARCH GROUP ON MARINE BIOGEOCHEMISTRY AND GLOBAL CHANGE, n.d. Web. 10 Apr. 2017. -http://biogeochemistry.org/index.php?option=com_content&view=article&id=5&Itemid=6-). With these skills he is able to accurately explain how the PH levels in the ocean are rising and is able to explain the effects of this.

This video explains how CO2 is entering the oceans and releasing hydrogen ions, raising acid levels in the ocean. It also, in detail, explains the effects of the ocean acidification. 


As a learner, the visuals made it a lot easier to understand. The professional grade animations really made it easier to see what is going on. References from credible sources like Dr. Carles Pelejero really made the information seem more solid.

Clean Energy Source Demo

Methanol: 
.Energy in methanol glows light blue
.Not lots of carbon is being released and the blue is an indicator
.Burns fairly slow

Ethanol:
.Very light blue
.Burns very fast

Gasoline:
.Orange shows it is very energy dense
.The black smoke is carbon dioxide going into the atmosphere
.Flame the largest

Candle:
.Made of hydro carbon
.A bit cleaner than gasoline

Cellulose:

.Burning wood, brush, or any similar energy
.Dirtiest form of energy of the sources presented

*The best energy source of all of the sources would be gasoline for efficiency at this point in time. Cellulose is energy dense foe a while, but releases too much carbon dioxide. Candles are not efficient. The other two sources ethanol and methanol are clean sources of energy, but cost a lot to export and import and are nowhere as efficient as gasoline. Even though gasoline is not a very desirable option, it is the only one of the presented sources that works.



Images of the Demo being presented. The one on the left is gasoline burning.

Water Labs (Notes)

Drinking Water Lab:

Testing for

~Results will be present in 48 hours

Procedures:

. Place 2 drops of water sample onto strip
. Put 5 ml of water into each tube with powder
. Shake the tubes
. Place tubes in an incubator set to 80 degrees Fahrenheit or 25 degrees Celsius
.

Facts:

2% of water on Earth is drinkable
Tap water is filtered out of lakes, ponds, reservoirs, oceans (not as common), etc.

Chlorine:
. Is harmful to the environment
. A pale green gas
. Reacts with other chemicals

Pond Water Lab:

Macroscopic: Something that isnt microscopic; it is large enough to with the human eye
Microcopic: Something that isnt macroscopic; something that cant be seen by the human eye

Pond water contains a number of different macroscopic and microscopic

Ponds are stangnant

Stagnant bodies of water don't move

Bacteria breaks down

184 bacteria species in a pond

pH Levels of Water Lab:

Testing pH Levels in Water:

Procedures:


Ocean went from 8.0 average to 8.1-8.2 in past yeats
