Post-Assessment for Ocean Acidification

Instructions: This survey will be used as a way to assess your understanding and the effectiveness of the lessons you just completed. Please try your best to give an answer to every question, even if you need to guess. It is important for us to see where your thinking is. We thank you for your time and thought.

Question Title

* 2. How many people can contact 1A? (Choose the best answer.)

Question Title

Question Title

* 6. Various things are listed below. Select all of the things that can be thought of as a system.

Aquarium

Bicycle

Ocean

Box of Nails

Question Title

* 7. Explain your thinking in Question 6. How did you decide whether something is a system?

Question Title

* 8. What do you think systems thinking is? Describe a time when have you used systems thinking.

Question Title

* 9. If you were going to do a systems level study, what do you think it would involve?

Question Title

* 10. Describe an example of an emergent property.

Question Title

* 11. Give an example of how your actions have a large impact on the environment.

Question Title

* 12. What are some ways that carbon dioxide gets into our atmosphere?

Question Title

* 13. Explain the connection between carbon dioxide in the air and carbon dioxide in oceans and lakes.

Question Title

* 14. Describe the experiment(s) you conducted. Include your question, a brief summary of your procedure, materials used, a description of the data that you collected (including a description of any graph(s) that you made), results, and conclusions.

Question Title

* 15. If you had more time, what other experiments would you perform?

Question Title

* 16. What interest group did you study? What information about your interest group did your experiment(s) give you?

Question Title

* 17. The “amount of light and temperature” are often coupled in the environment. What do you think this means when experimenting with these factors in the lab? Is this a good thing, a bad thing, or just something that must be considered?

Question Title

* 18. Why are diatoms a good organism for study?

Question Title

This is a picture of diatoms (photo from http://www.ucmp.berkeley.edu). Most diatoms are small, single celled plants (phytoplankton) living in the sea.

Question Title

* 19. Which of the following comparisons between pH and a centimeter are true? (Select all that apply).

pH tells us how acidic or basic something is; centimeters tell us how long or short something is.

There are many ways and tools to figure out the pH of something; there are many ways and tools to figure out how many centimeters something is.

Both pH and centimeters are measured on linear scales. In other words, when a plant grows from 4.0 centimeters tall to 8.0 centimeters tall, it has doubled in height; when the ocean increases in pH from 4.0 to 8.0, it has doubled in alkalinity (how basic it is).

Both pH and centimeters are measured on logarithmic scales. In other words, a solution with a pH of 8.0 is 10 times more alkaline (basic) than a solution with a pH of 7.0, and a string that is 8.0 centimeters long is 10 times longer than a string that is 7.0 centimeters long.

Question Title

* 20. Please describe why any of the above statements in Question 19 is/are NOT true.

Question Title

* 21. How can you assess the reliability (accuracy and trustworthiness) of something that you are reading, such as a newspaper or online article?

Question Title

* 22. Do you think that Ocean Acidification is a hotly debated topic? If so, why? If not, why not?

Question Title

* 23. Explain how Ocean Acidification is connected to the economy.

Question Title

* 24. On a separate sheet of paper, draw a flow chart or network diagram showing what specifically happens when carbon dioxide (CO2) is produced by anthropogenic processes and makes its way to the sea. (Side note: Anthropogenic definition = of, relating to, or resulting from the influence of human beings on nature). CO2 production should be your first step. Next, include as many steps and as much information as you can in your diagram to show where CO2 goes, any chemical reactions that happen, and what might result. “End” with any effects on various specific sea life and human economies.
