Dobbs' Dynamos

6th: ) Our Warm-up came from page117 # 11, where we looked at a map of our state and discussed the granite in Elberton, Ga. and the many places it is used and how it got there in the first place! We then had our test, discussed our foldable on rocks, then had a short video on rock formations in the United States. You have no homework, but your warm-ups will be due on Friday.

7th: )We know that the mitochondria is where sugar  is borken down to produce energy. What is the name of the place where it is stored before it is realeased? It is called the ATP (adenosine triphoshate). We did some review before your test today. After the test we watched a short video about cells and cell division. For tomorrow you have no homework, but your Warm-ups are due on Friday.

6th:If a rock is buried deep inside the Earth, which geological processes cannot change the rock? Explain your answer. A rock buried deep beneath the surface cannot be changed by weathering and erosion, which are gelogical processes that change Earth’s surface features. After the discussion we went over our study guide, worked on our foldable of the three rock types, then did more review for our test tomorrow. Your Chapter 4 test is tomorrow.

7th: Explain the relationship between structure and function. Structure is the arrangement of parts in an organism. It includes the shape of a part and the material of which the part is made. Function is the job the part does. After the discussion, we  had our Section 3 Quiz. We then did more review of Chapter 3. Your Chapter 3 test is tomorrow.

6th: Your Warm-up came from page 115, #’s 22-25. We completed the questions from the chart and made a pie graph to represent the data. After the discussion, I returned your quiz from Friday and we then began our review of the chapter with a study guide. Tomorrow we will make a foldable on the three rock types and review for your Chapter 4 test on Wednesday. Complete the study guide for homework, if you didn’t finish it in class.

7th: Your Warm-up came from page 62 “Math Focus” where we used cubes to represent surface-area to volume ratio. We then did a review of Section 3.  You will have a quiz on section 3 tomorrow.

6th: )Describe the process of deformation. In deformation, the shape of rock is changed  by the forces placed on it. the rock could be squeezed, stretched, or folded, I did a demonstration of this using clay. After the discussion, we completed our Chapter 4 quiz. Other than working on your “If I were a rock or a mineral” projects, you have no homework.

Watch the videos of rocks forming!

7th: )Our Warm-up came from page 84 # 1, where we read a table to find the correct answer about cells. After some review of Chapter 3, we watched the video ” Human Body in Action.” For homework you need to be studying for your Chapter 3 test which will be next week.

6th: ) What is the difference between contact and regional metamorphism? The difference between contact and regional metamorphism  is that contact metamorphism is rather local, and is caused by magma heating nearby rocks. Regional is over a large area deep below the surface where tectonic forces deform large areas of rock. We did some review of Section 4, plus some more activities with our rock samples, then began work on our “If I were a rock” project. I can’t wait to get your responses to this one! You will have a quiz on Chapter 4 tomorrow.

7th: ) What are three advantages of being multicellular? Three advantages of being multicellular are: larger size, longer life, and cell specialization. We discussed the question, then did a comparison of prokaryotic and eukaryotic cells and eventually continued with our further investigation of cells and the organization of living things. We then worked on a foldable using cell, tissue, organ, and organ system, these are due for homework tomorrow. You will also need to have your Chapter 3, Section 4 Directed Reading work completed.

6th: )How do geologists classify metamorphic rock? Geologists classify metamorphic rock by the arrangement of the grains, whether they are foliated or non-foliated. We did a lab where we categorized rock samples based on a dichotomous key. We also looked at some samples of metamorphic rock and put them in categories of foliated/non-foliated. After some review, we then worked on Section 4. If you didn’t finish this section in class, it is due for homework.

7th: ) Your Warm- Up came fro page 83, #’s 24, 25, and 26, where we looked at a cell and made some decisions about its parts. We then reviewed Section 2, and next had our quiz. For the remainder of the class we worked on our vocabulary words for Section 3. If you didn’t finish this in class, it is due for homework.

6th: )Explain how index minerals allow a scientist to understand the history of a metamorphic rock.Because index minerals form only at certain temperatures and pressures, index minerals indicate the temperature, pressure, and depth at which a rock metamorphosed. We discussed the question thoroughly, then had a great lesson on rocks, minerals, and fossils. These samples came from the Tellus museum and contained a ton of information about each one…what a fun, learning day! No homework, we were too busy having a “rocking” good time.

7th: )Scientists are using DNA to identify related groups of termites. Where is DNA stored in termite cells? Describe the structure and function of this cell part. Termites are eukaryotes, and their DNA is found int he nucleus of their cells. The function of the nucleus is to contain DNA. The nucleus is surrounded by a double membrane with pores that allow substances to enter and exit. After the discussion, we reviewed and then completed the work for section 2. Your quiz on Section 2 will be tomorrow.

6th: )Describe the three main categories of sedimentary rock. Clastic sedimentary rock forms when sediments are compacted and cemented together. Chemical sedimentary rock forms when dissolved minerals separate out of solution and crystalize. Organic sedimentary rock is  made from the remains things that were once living (like plants and animals). I gave each group some sedimentary rocks and had each group put the rocks into categories, distinguishing between the three categories of sedimentary rocks. We then went on to Section 3 with a discussion of sedimentary rocks. For tomorrow you need to complete Section 3. Have a wonderful evening!

7th: ) How do you know the cells inside your body are working? You know the cells inside you are working because you are alive: you can breathe, digest food, and move. I returned the quiz on Friday, I was amazed at the wonderful grades on these papers, sure makes grading easy! I introduced Section 2 of Chapter 3, it was then on to presentation of your “Cell City” projects. For homework you need to complete your vocabulary cards. You will have a quiz on Section 2 on Wednesday, maybe Thursday depending on how much we get done tomorrow. Have a wonderful evening!

6th: )Why would sedimentary rock have to become metamorphic rock before it becomes magma?Sedimentary rock would have to be pushed into the mantle and the pressure and heat of that process would change it into metamorphic rock. When it’s pushed deep enough it would melt into magma. We had a discussion on the question, then I checked your Warm-ups for the last two weeks. You explained your creative vocabulary games and got to enjoy playing them after we had finished our lesson. Most of you completed Section 2 in class, if not it is due on Monday.Have a great weekend!

7th: ) Why do all cells, both eukaryotic and prokaryotic, have ribosomes? Ribosomes are the organelles where proteins are made. All cells need protein in order to live. After the discussion, I checked your Warm-ups for the last two weeks, then we did a lot of review. It was then on to our quiz. We  had some time to work on your projects, which are due on Monday. Have a great weekend!

6th: Describe four processes that shape Earth’s Surface.  Weathering is the process by which water, wind, ice and heat  break down rock. Erosion is the process by which sediment is removed from its source. Deposition is the process by which sediment moved by erosion is laid down. Uplift is the process by which rock within the Earth moves to Earth’s surface. We did a little “mini lab” on these different processes, and another demonstration on how the shell of an egg is really…limestone (CaCO3)! We reviewed from Monday, then went on to Section 2, your homework is to come up with a creative idea for our vocabulary words from this chapter.

7th: ) Our Warm-up came from page 67, #’s 9, 10, and 11, where we interpreted a graphic of a eubaacterial cell. We reviewed section 1, then watched a short video about the cell. Next, we did a lab with an egg and discussed the parts as it relates to a Eukaryotic cell. For the remainder of the class you worked on your “Cell as a City” projects which are due on Monday. You will have a quiz on Section 1 on Friday, you need to be studying some every night.
