Tittle - The Effect of the Composition of Water on absorption of carbon dioxide
Topic Introduction - Ocean Acidification was a serious problem. Levels of C02 have been rising creating carbonic acid ( H2CO3) in the ocean. Shellfish needs carbon dioxide to produce its shell, but too much amount of carbon
is harmful to living organisms.H2CO3 affects coral ref, breaks down molecules so critter can't build their shells.
Experiment question - When it absorbs carbon, what are the effects of water?

Experiment question - When it absorbs carbon, what are the effects of water?
1. What gas are you blowing into the water?
- CO2
2. What happens to the gas when you blow it into the water?
- Became bubbles
3. How are you measuring change in the water during this lab?
- Changing color and pH #
4. What does measuring the pH of the water tell us?
- Acidic <-> 7 <-> basic
5. After studying the reaction above, how do you think carbonic acid will affect the pH of the water?
- CO2 + H2o = H2CO3 ( carbonic acid)
Hypothesis - Bubbles Protocol - If the carbon dioxide (CO2) get into the water ( H2O), then it will make carbonic acid (H2CO3) in the water, changing color and pH # nearly to acidic point.
Hypothesis - Shells Protocol - If the shells in the vinegar instead of sea water, then it will dissolved a lot more.
- CO2

Control experiment:
- Timer, blower, and recorder.
- Place 100mL of salt water into 200mL beaker.
- Add universal indicator into that salt water, stop drop when you see the color changing.
- Cover the beaker with saran wrap.
- Use the straw to make a hole into the saran wrap.
- Blow the air in the solution for 2 min
- Time and record every 30sec.
Cold seawater:
- + 100mL of saltwater into 200mL beaker.
- Place it into an ice container for 3 min
- Repeat steps in control experiment.
Hot seawater:
- +100mL of saltwater into 200mL beaker
- Place it into a hot water container for 3 min.
- Repeat steps in control experiment.
Tap water:
- + 100mL of tap water into 200mL beaker.
- Repeat steps in control experiment.
Variables:
- The constant variables of this experiment are the amount of water and type of wrap
used. The dependent variable is the pH of the water. The independent
variable is the type of water.
DATA ANALYSIS
1. As you blew through the straw, what were you adding to the water and how did that change the
pH?
- I was adding C02 to the water as long as I blew through the straw, that creates stronger acidic in the water.
2. What did the universal indicator tell us about the water?
- pH of the water.
3. What does this tell us about the affects of carbonic acid in ocean water?
- When carbon dioxide mix with water, it will become carbonic acid that harmful to people.
4.Based on the results of your experimental protocol, which factor affects the pH of the water
most, temperature or salt?
- Salt is the factor that affects the pH of the water the most, salt changed the color and pH of the water in the very first minute, but the tap water keep constant the result.
CONCLUSION
My initial hypothesis was if the carbon dioxide (CO2) get into the water ( H2O), then it will make carbonic acid (H2CO3) in the water, changing color and pH # nearly to acidic point. My data shows my hypothesis is supported. The pH levels increased make changing color of the water.
Through this experiment, I've known pretty much about the carbonic acid in the water. Salt water could change its pH and color real fast. The temperature didn't affect as much as the salt in the water, so then, salt water represent for our ocean. There was too much C02 released from people to atmosphere, and from atmosphere to the ocean create acidic, increase day by day.

Shell Protocol
Title : High rate of carbon dioxide impacts on the seashells
Central question : How does pH of water affect the seashells?
Overview of experiment : Most of sea organisms have CaCO3 on their shells for protection. When acidity levels rise up ( CO2 also ), then the calcium carbon starts to dissolve. Also, with highly rate of acidity or CO2, the animals extremely get difficult for creating their shells.
Pre-lab questions :
1. How do organism make their shells? What are shells made of?
- They combine calcium with carbon to make calcium carbonate in order of construction creating their shells. So basically, we could conclude so far that their shells made of carbon and calcium.
2. What do you expect to happen to the shell in an acidity solution such as vinegar?
- Vinegar is a high acidic liquid with pH2, I predicted the shell will strongly breaks down in this solution.
3. What are sources of CO2 and which of these sources are most likely to affect ocean pH?
- The respiration, released gases from technologies, etc. are sources of creating CO2, but the biggest source is burning fossils and coals. It's most likely to affect ocean pH, because CO2 from burning coals and fossils released up to the atmosphere then absorbed back to the ocean.
Hypothesis - If the shell is placed in the vinegar, then its shell will breaks down faster than the shell that is placed in the seawater.
Protocol - Place the shells into the vinegar and seawater beaker in 2min, then observed what happened to those shells in every 30sec.
Data analysis
1. When you immersed the shells in vinegar how did you know that a reaction was happening?
- Once I immersed the shell in vinegar, I knew a reaction was happening because immediately the shell bean bubbling.
2. How did observing the shells in vinegar relate to how animals are affected by a lower pH of ocean water?
- By observing the shells dissolved in the vinegar, I can know how the acidity impacts on the animals shells, this lab gave a good image about the real ocean life, I think it's worse down there because they've been there for a long time, the breaking down of their shells
3. How would shelled organisms be affected by a lower pH of ocean water?
- They enable to creating their shells with strong level of acidic in ocean water. Organisms shells pilled off and broken apart. Without shell, they couldn't exist.

CONCLUSION
Over all these experiments done above were a great way to understand ocean acidification and too, see how serious it really
is. With these experiments you not only get background information about the problem, but you get to test it and see with
your own eyes what ocean acidification really is and how it can effect sea life.
Honestly, I had a lot of fun doing this. I learned a good handful of things. So in conclusion let's be more aware of how much carbon dioxide we throw out into our atmosphere. We may think we're only affecting ourselves, but that's not the case. We are affect the sea life as well, it's natural beauties and it's useful resources.
