Interview Sixth Grade Life Science Students On The Topic Of Cell Division

Website to go for quizzes and activities: Print out the quizzes for mitosis and meiosis http://www.phschool.com/science/biology_place/labbench/

“All types of cells undergo mitosis during formation of the embryo, but many adult cells, such as nerve cells, lens cells of the eye, and muscle cells, lost their ability to replicate and divide. The cells of other tissues, particularly epithelial cells [e.g., of the intestine, lung, skin), divide continuously and rapidly, competing the entire cell cycle in less than 10 hours” (McChance & Huether, pg. 35).

Cell culture was a very important area in which HeLa cells were used. Because of HeLa cells, they were able to have large quantities of cancer cells with which to conduct experiments. The cells were given to scientists and researchers who passed them on to others who gave them to even more scientists and researchers. The cells were injected with different drugs in the hopes of finding a cure for cancer and other diseases. HeLa cells did not grow like normal cells but were able to divide an unlimited number of times and provide unlimited amounts of cells for research. During our first semester we learned about cell division and how cells could only divide a certain number of times. HeLa cells were cancer cells taken straight from a cancer tumor and they defied this basic principal of cells division.

The teacher first poses a question to the students, such as ‘How do we study cellular structures?’, activating the engagement stage of the bscs learning model. Once the topic has been broached, the teacher will

science -inquiry concepts. In the video clip from lesson 4,minute Students will work together to form hypothesis, observe ,follow procedure ,collect and analyze data, write a conclusion. This lab has four stations, with each stations student were dealing with situation involving phenomenon that they see outside of the classroom, likely on daily basis. so, with each station the Students can be seen using data and their observations as evidence to explain why they were seeing this real-world phenomenon. then students need to answer the lab analysis questions that also connect them with real world. video 2. Furthermore, to help students construct their explanations, I asked questions that push students to make connections to the real world. For example, in video 2, minute , I ask students why organic compounds dose not conduct electricity ? and how about if we try using water and salt ?

the concept that the cells were not immortal but replicated millions of times over. However, it

The chapter we will be working on is cell division and reproduction. I began the lesson with a bell ringer followed by notes on presented in a PowerPoint on the SmartBoard. The students asked questions throughout the note taking processes. I used a chart in the PowerPoint to help students understand the cell cycle of reproduction. The 7th-grade class began the chapter on the Earth's water and the water cycle. Throughout this lesson, the students had many questions. Again I used diagrams to help show the steps that occur in the water cycle.

Ask students if they have ever heard of DNA. Help them to understand that DNA (deoxyribonucleic acid) is a molecule that carries most of the genetic instructions used in the development, functioning and reproduction of all known living organisms and many viruses. It might be easier for them to understand that the reason you are

The AP Biology course’s second key concept is: “biological systems utilize energy and molecular building blocks to grow, reproduce, and to maintain homeostasis.” One of the main points encompassed in this idea is cell differentiation, the process by which cells specialize in structure and function, highlighted in chapter 16. Cell specialization is an overarching concept that connects to the idea that the coordination of specific events is necessary for the normal development of an organism.

This passion for science was molded and transformed by the University of Michigan. Here, I was not only taught the important cellular functions but I was also taught how these cellular functions were postulated. I was also encouraged to do research. The amalgamation of these 2 experiences helped me to think like a scientist and instill a scientific mentality and approach. This comprehensive scientific approach is

“We are examining mitosis, microtubules, and the idea that all cells need to replicate. We make the replication process easier to understand by starting at the smaller part of the human, the cell. Additionally, the concept that DNA replicates into identical copies of itself is made simpler by first looking at plants and then later to animals.”

Cell division is when a cell divides to produce two daughter cells with the same genetic information. In cell division, specialized cells are created from multicellular organisms and work to carry out different task and make tissue. Since specialized cells work together on multiple task they use less energy and carry out functions productively. When repairing weak cells, such as skin cells, cell division helps mend the cells that have specific functions to complete.

first learned about stem cells, I found them instantly interesting. My International Baccalaureate biology teacher

My Student Exploration packet of Cell Divisions, was the very first gizmo assignment handed to me by my science teacher, Mr. Moreno. I had recently been transferred to his class, so I didn’t understand what the rest of the class was doing. Fortionally, I used my quick thinking to boost myself up to the level everyone else was at. I read all three of the science books to understand the topics that they were studying. My former class were learning about outer space, but in my new class we were surveying topics about the body, like cells. Anyways, this assignment required for me to use all the knowledge I learned in the short time I was in this new class, and to do further research in Gizmos.com, to grasp

My research about stem cells, I will be talking about what a stem cell is. Why are stem cells important from a medical perspective? How are stem cells being used today? Where do scientists get stem cells? Why is so much controversy over the stem cells? How does a zygote develop into a baby? Why a zygote is considered a stem cell? A stem cell is an immature cell that can help reproduce different types of cells throughout the body. There are three types of stem cells that I will be focusing on : adult, embryonic, and totipotent stem cells. Adult stem cells can be found in children and infants. These stem cells are found in small numbers in most adult tissues, such as bone marrow or fat.Adult stem cells are used to repair tissue throughout the body, therefore the adult cells are used to replace dying or lost cells in the body.Totipotent stem cells are the one and only type of stem cell that can be used anywhere throughout the whole body.They are formed when a sperm cell and a cell egg unite to make a one-celled fertlized egg.The research on all the cells is limited because of the challenge receiving them in laboratory.
