'A'ohe Kula- La o na Pelekikena (No School-President's Day)
Marine Debris by Type- sort and compare to National data from Ocean Conservancy.
Homework for ALL STUDENTS
1.Follow this link to a table showing data for biodegradation of selected marine debris:
This data is from MOTE Marine Lab and was published in 1993.
2. Choose 10 items of debris from the list and make a table with the debris items listed in the first column and three additional colums to the right. Each of the other three columns will list estimated length of time it takes for the debris item to breakdown or bioegrade.
3. You will need to populate the table with THREE different sources for biodegradation timeline. You may use the MOTE Marine lab data as one of your sources.
Each source will be the top row in either column 2, 3 or 4
4. Complete the table in your Science Inquiry notebook under the heading "Biodegradation of Marine Debris - A Comparison"
5. After you have completed the table, note any significant variations from the different sources in the times listed for an itme to breakdown. What are some possible reasons for the differnet length of time given? Which source(s) do you have more confidence in, why?
Due by Friday notebook check
"I am...I Have" (Review chemical and physical properties)
An Elemental Question, Part 2
Homework Student reading: "A Historic Overview: Mendeleev and the Periodic Table"
Complete the following reflection in your Science Inquiry Notebook under the heading " An Elemental Question- Historic Overview"
1. How did your lab group approach the problem of developing a system to organize the 60 elements known to Mendeleev?
2. What were the strategies that you used?
3. What did you do when you encountered a problem that your system could not solve?
After reading , the article, describe how chemists Johan Dobereine , John Newlands and Dmitirii Mendeleev approached the problem of classifying the elements according to their properties.
These three scientists were certainly not the only ones to work on organizing the elements based on their properties, but their work did allow Mendeleev's table to be the first to illustrate..._______________ (FILL IN THE BLANK, the answer is in the reading)
Due in Science Inquiry Notebook check on Friday: Practice Self-Direction, do not leave all of your science homework for Thursday night!
Chemical Strucuture Review (modelling and guided notes)
Distribute Group Presentation Assignment outline and rubric for "Bio of A Chemist Group Presentation"
Homework: "Elements of Chemistry- Subatomic Particle"s handout. Due Monday
Science Inquiry Notebook Check due tomorrow
Web Extensions for the Week
Students, please note: These are the only Extensions that may be accessed during class time. It is a KCS Student Handbook Tech Violation to access unauthorized web material during school time.
Chemical elements and molecular strusture interactive
View complete layout of Periodic Table. Search each element for details, shows orbitals, common compounds formed
Click on any of the elements in the table for photos, where the elemnts are found and lots of interesting information. DO NOT surf outside of the table and the elements on the site DURING CLASS TIME (you can explore other site features on your own time)
Science Friday Virtual Assignment
We will return to marine microbes and how they impact biodegradation NEXT WEEK.
This week, for Science Friday, take extra time to prepare your notebook for check. Make sue all of the assignments for the week are neat and organized and complete your table of contents.
