6th Graders - No homework! 
Congratulations to my Period 1 class for winning the 6th Grade Color Contest!  Almost everyone showed school spirit by wearing green today!

7th Graders: Read (and re-read) "Study Guide: Cells", which we went over in class today.   Note a correction to the answers: the blank in number 5 should read: "TAKE IN NUTRIENTS".

Remember:
Plant cells have a CELL WALL (and a cell membrane), Big VACUOLE, and CHLOROPLASTS that absorb light to power the process of making the plant's food. 

Animal cells have NO cell wall, NO Big Vacuoles, NO Chloroplasts, but they do have Lysosomes and Centrosomes.  Check out the diagrams on the last page of your "Study Guide: Cells".

25.  New Question: REad the following text, and look for a definition in the text:  
"Goldberger investigated Nutrition, or balanced vitamins and minerals in food, as Pellagra's cause."  Based on the reading, what is the definition of "Nutrition"?

Gr. 6, per. 6 - Elements of Jewelry: read and answer 10 questions

• Grade 6 homework:  Complete Questions 1- 26 of Test Prep paper, which students began working on in class today, before tomorrow's Unit test.
• Grade 7 Homework:  Complete Study Guide:Cells,  which we started working on in class today.

Grade 6 Homework:

• Read your study guide through at least one time, and 
• answer all Questions on the Reading Product Labels Activity Sheet (BOTH sides, CR!) and
• Also write "Question 11: What kind of hazard(s) does this cleaner  present?" Then write out an answer to that question.

Gr. 7 homework:

• Read your study guide through at least twice.  Make sure that you know your material for tomorrow's Mid Term. If you have questions, you can email me at mgoldsmith@ci.stamford.ct.us and I will answer you in class before the test 

End of Answers for Study Guide

• Describe the tradeoffs associated with using one power of magnification over another. 
• At a higher power, you see fewer cells, but you see those cells in greater detail.

• Explain the function of the four most common organelles.
Nucleus - reproduction and controls the cell
cell membrane - controls flow of materials in and out of cell.
mitochondria - energy factory for the cell.
cytoplasm - breaks down and allows transport of nutrients.
• Compare and contrast bacteria vs. animal cell organelles.
bacteria do not have nucelus or membrane bound organelle.
• Compare and contrast single vs. multi-celled organisms and provide examples of each.

• Multi-celled organisms have more than one cell, but they have trouble moving nutrients and oxygen around, so they developed tissues, organs and organ systems of great complexity, such as our circulatory systems with a two-pump heart (one side pumps to the body, one side pumps to the lungs), and blood that contains oxygen carrying red cells and white cells that fight foreign cells and substances. In other words, they developed cells that were more specialized in function and structure, with greater numbers of organelles (parts with their own job). Ex: Worms have less complicated breathing and digestive systems than humans, and dogs; algae has less complicated systems than trees.
• Single-celled organisms. The cell controls what nutrients, oxygen and waste go in and out of the cell, because all needed substances simply pass directly between the organism and the outside environment. No specialized cells, only one cell must perform all functions, and the organism is much more limited in what it is able to do. Ex: bacteria can't think; can't hunt, consume and digest other organism

Welcome back after our long weekend -

Sixth grade homework: Per. 1 - Physical and Chemical Properties

Seventh grade homework:  Review the Study Guide and answer the first two pages of questions.

Hi students - Sorry I wasn't there for most of you today.  Homework assignments:

1. 6th Graders - study your Review packets for your Mid Term Exam tomorrow.  You can also try a Quizlet put together by Mrs. Bridgers, at https://quizlet.com/114712420/flashcards

2. 7th Graders - Why are Cells Shaped Differently?  Put your work in the homework box tomorrow at the start of class.

Wednesday, 1/13/16 - I'm just going to revise yesterday's blog entry so the 6th Grade review sheet is still available for anyone that needs it.

Homework:

6th grade: complete the study guide and define each term, answer each question under the sections headed "Vocabulary" and "Analysis Questions".  (Review the Science Process Skills section at the beginning, but do not write out details on the skills). I've posted copies of the original sheets without the additions from class, below if you left yours at school......

7th grade:   Respiration packet.  Second set of Multiple choice questions is redundant, don't need to answer those. The Word scramble at the end is for fun, not a grade.  Those of you who picked up the challenge work (2-7 How do Materials Move in and out of Cells?) today can earn extra credit by turning that work in no later than Monday.




Sorry for the late blog post, but my classroom computer has lost internet connectivity.

Homework:
6th grade: Go through the study guide and define each term, answer each question. Minimum 1 full page of the sections headed "Vocabulary" and "Analysis Questions".  (Review the Science Process Skills section at the beginning, but do not write out details on the skills). I've posted copies of the original sheets without the additions from class, below if you left yours at school......

7th grade:   w/s 2-3 What are the Other Parts of a Cell?
