Last week we learned that we are what we eat because we consume proteins, fats, carbohydrates, and water which then becomes our cell membranes, cytoplasm, and other organelles (It's a very odd thing, as odd as can be, whatever I eat, it turns into me!). Interesting!
This week we have explored how these compounds move into and out of the cell membrane (diffusion and osmosis). Today was a quick SWYK on the vocabulary terms diffusion, osmosis, passive transport, active transport, and selectively permeable. We also discussed the energy passed along in our foods through food webs and energy pyramids (textbook pages 44-45)! IF YOU WERE ABSENT YOU SHOULD PRINT THESE NOTES AND ATTACH IN YOUR NOTEBOOK ON PAGE 73. Tomorrow we shall discuss the process of photosynthesis in more depth.
Today we EGGSplored osmosis and observed that water does indeed move from high concentration to low concentration without any help or energy at all! ALL ABSENT STUDENTS NEED TO CLICK THIS FOR THE RESULTS OF YOUR EGG (remember if you were egg 1, 2, or 3 AND if sugar or distilled. You also need the class average in your data table for BOTH types of eggs in addition to your 'own' egg). Tomorrow the lab is due: finish analysis/conclusion questions tonight AND be sure to have all the vocabulary from this section in your glossary (diffusion, osmosis, passive transport, active transport, and selectively permeable). SWYK tomorrow and energy processes begin! Please stop to see me in the morning with questions or PRIDE after school!
Today we continued with our learning of diffusion and osmosis. We set up eggs in either pure water (high) or corn syrup (low) and will re-measure the mass tomorrow. I wonder what will happen? We also read about passive and active transport today p. 36 (IF YOU WERE ABSENT BE SURE TO PRINT THESE NOTES AND ATTACH TO PAGE 71 OF YOUR NOTEBOOK). Tonight you should be sure all vocabulary from this section is in your glossary (diffusion, osmosis, passive transport, active transport, and selectively permeable). Fun stuff!!!
Some folks need to finish the Chemistry of Cells work from last week. Reminder of PRIDE this week (I will
be there as teacher helper on Wednesday) as well as to scroll all posts from last week for help/information.
Today we explored diffusion and osmosis. We read the textbook pages 32-35 and took notes on page 70 in our textbook. IF YOU WERE ABSENT YOU SHOULD PRINT THESE NOTES AND ATTACH TO PAGE 70. Monday we will 'eggs'plore osmosis in more depth. Watch today's video again for awesome gummy action!
Today was a day to get all the work from this week caught up: notes about the chemical compounds in cells; p. 29 #1-4; p. 30 EOSQ's 1 a, b, c, 2 a, b, c, 3 a and b; PLUS finished the paragraph explaining that we are indeed just what we eat. Watch the video below if you need a reminder of the molecules found in our foods AND our cells... yep it's a review! Finish all work tonight if not done! Scroll through the week's posts as well to see if you missed any details or helpful information... Tomorrow we learn just how the cell membrane works!
Today we turned in our work from pages 29 (Math: Analyzing Data) and EOSQ's from p. 30. Some of us need to redo the work tonight because we did not answer using complete sentences. Some of us need to DO the work! We also wrote a summary to assess our understanding of the chemicals in cells (click to watch the Ted ed again). Maybe you still need to finish writing the summary? Explain the poem 'It's a very odd thing, as odd as can be, whatever I eat, it turns into me!'... full CEAEAEAL paragraph writing here! Due tomorrow!
Reminder to those who did NOT do a cell project: your task is to build an atom model (not a research poster) of an element found in cells. Due Friday. THIS IS A SEARCH OF MANY SITES TO HELP YOU DO THIS TASK.
Even when I'm not there! Today you should have had a work day to finish (check) notes as well as start (finish?) graph analysis and End Of Section Questions. If you were also absent today (I was not at school today) you will use a sheet of looseleaf and then answer questions 1-4 on p. 29 Math graph. Be sure your answers are using complete sentences! Next, on the same paper, answer the end of section questions (EOSQ's) on page 30. 1 a, b, c, 2 a, b, c, 3 a and b. Once again answer using complete sentences.
Tomorrow I shall be back and we will summarize the section 'Chemical Compounds in Cells' with a CEAL paragraph. PRINT THESE NOTES TO HELP
(I want snow... think snow please!)
Today we discovered the compounds found in cells: carbohydrates, lipids, proteins (amino acids), nucleic acids, and water. These compound names are the headings for your THIEVes notes (or you can make a chart) listing details about what elements make the compounds as well as the function (job or role) of each compound in the cell. Include examples! We already defined the terms elements, atoms, compounds, and molecules from (p. 25-26) last Friday. Tomorrow we continue understanding the chemical compounds in cells.
IF YOU DID NOT DO A CELL PROJECT:
You are expected to build an atom model since I don't have a grade for you in Standard 1.4: Modeling Scientific Concepts . Choose an element found in living things and create a model. YOU need to discover how (suggestion: google search 'building atom model'). Due by Friday 12/11. Required if no cell project turned in.
