Hey I'm very sorry I missed the exam I forgot we had class today is there is any way I can still take it
P.s. it’s my birthday if that makes any difference LOL
(after final grades have been submitted)Hi I just looked at my grade and I’m only 3% away from getting a C. I really need a C so I can go to [insert name of school here] next year. Is there any extra credit I can do?
(hours before an assignment is due)Hey my internet is not working very well can I give you the assignment tomorrow?
Please do:
• Read, understand, and agree to the syllabus.– You must sign a syllabus contract and submit it before the first exam.
• Attend my office hours.
• Contact me right away if you have extenuating circumstances that may interfere with your ability to participate in class (your own serious medical issue, family emergency, jury duty, religious observation).
• Let me know if you are registered with ACCESS. In order to take exams at the Testing Center, you must provide me with an appointment slip at least 48 hours prior to the exam.
• Ask for help if you are worried about how you’re doing.
• Keep track of your grades.
• Complete the extra credit.

What is one question you have about earth science?
The diatom Pseudo-nitzschia forms Harmful Algal Blooms (HABs).
• 37 species• 14 (?) produce domoic acid (DA)• Primarily coastal
razor clams, other shellfish

Learning Goals: Chapter 1
- Read Chapter 1, “Introduction to Earth Science”
- Key Points and Questions:
- How does the process of science work?
(observations, hypotheses, theory…
inductive and deductive reasoning)
- What are examples of connections between the four
components of earth science? (“Planet Earth” video)

1. What are two examples of interactions between two or more “spheres”:– Biosphere, atmosphere, hydrosphere, geosphere, exosphere
2. Write about one ecosystem you have observed in South Florida. How is South Florida similar to, or different from, one example in the video?
