Expectations, do your best effort. Be responsible for your own learning. Believe in your abilities. Confidence is mother half the battle. Read all text and supplementary materials as assigned. Try, and then try again. Complete all assignments as assigned. Safety laboratory safety is important. Although many labs are online, students will be conducting some labs at home.
Students will gain some understanding of secular evolutionary thought and come away strengthened in their faith. Many of the materials mention millions of years, and I cant get away from that, but the students will not be required to take any of that as fact. There is no test on evolution; instead, students finish that chapter by presenting their beliefs about creation and evolution. Thanks to jessica ryder for her help with this course. Materials needed, day 1 Print out your First quarter, grades sheet or use the. Keep in mind that your success in biology will be directly proportional to the amount of effort you invest. You should complete every activity assigned to strengthen your understanding of each concept.
Course description: This course is based on georgia virtual learnings High School biology course, though it pulls in other resources throughout. This curriculum includes topics such as the scientific method, cells, biochemistry, photosynthesis and respiration, mitosis and meiosis, dna and rna, genetics, ecology, evolution and creation, taxonomy, viruses and bacteria, protists and fungi, and finally animals. Students will learn through texts, videos, online interactives and through hands-on and virtual lab investigations. (The gvl pages sometimes have links to discovery Education videos. You will not be using those. Just follow the directions in the course below as to what materials to use each day.). Notes: I believe in a literal six-day creation of the world by our holy, loving, almighty, creative god. This will be discussed in the beginning of the course to give the framework for how evolution will be approached. Natural selection is taught as it corresponds with Biblical truth but not beyond that.

(Antiterrorism Scenario training, page 2). Home security can be improved with self-help measures like changing locks, securing windows, and improving outdoor lighting. True or False: In an active shooter incident involving firearms you essay should immediately lie on the ground. Please note: This course is being removed July 1st. There is an updated biology course available.
You could consider switching over when you get to the end of a quarter. If you are having trouble with files and videos in this course and want to switch as soon as possible, you could switch at the end of a main unit. It wont affect you on the final to switch courses, but there are different assignments, so the grading sheets are different. Updated biology course, please review the faqs and contact us if you find a problem. Credits: 1, prerequisite : Middle school biology and chemistry, recommended: 9th or 10th. Test Prep: clep biology, this course covers the basic material for this exam, but this is considered a very hard test, and I would suspect more will need to be studied to learn everything required for this huge exam. Its worth the same as two college courses which is why it covers so much.
Lab 1e using the materials gathers, prepare a wet mount slide of the epidermis of an onion. . Draw what you see of the onion cell under the microscope. . Add several drops of the nacl solution to the slide. . Now draw the appearance of the cell. Data: Lab 1a table.1 Contents Initial Color Final Color Initial Presence of Glucose final Presence of Glucose bag 15 Glucose/ 1 Starch Solution clear Dark blue beaker H2oiki orange to brown Orange to brown _ lab 1a questions 1) Glucose is leaving the bag. The change in color of the contents of the bag and the presence of glucose in the bag prove this.
2) In the results, the iki moved from the beaker to the bag, this caused the change in the color of the bag. . The iki moved into the bag to make the concentrations outside the bag equal to inside the bag. . The glucose solution moved out of the bag making glucose present in the beaker. . The glucose moved to make the solute concentration inside and out of the bag equal. 3) If the initial and final percent concentration of glucose and iki for in the bag and the beaker were given, they would show the differences and prove the movement of these substances to reach dynamic equilibrium. 4) Based on my observations, the smallest substance was the iki molecule, then the glucose molecules, water molecules, membrane pore, and then the starch molecules being the largest. 5) If the experiment started with glucose and iki inside the bag and starch in the beaker, the glucose and iki would move out of the bag to make the concentrations equal, but the starch could not move into the bag because its molecules are.

Put each bag into a beaker of distilled water and let stand for half and hour. . After 30 minutes is up, remove each bag and determine its mass. . Record all data in its appropriate table. Lab 1C sing the essay potato core borer, obtain 24 cylindrical slices of potato, four for each cup. . Determine the mass of the four cylinders. . Immerse four cylinders into each of the six beakers or cups. . After time is up, remove the cores from the sucrose solutions and mass them. . Lab 1d using the paper, pencil, and calculator collected, determine solute potentials of the solutions and answer the questions asked to better understand this particular part of the lab.
Lab 1E n, lab 1E these items are needed: a microscope slide, cover slip, onion cells, light microscope, and a 15 nacl solution. Procedures: Lab 1a after gathering the materials, pour glucose/starch solution into dialysis tubing and close the bag. . Test the solution for presence of glucose. . Test the beaker of distilled water and iki for presence of glucose. . Put the dialysis bag into the beaker and let stand for 30 minutes. . When time is up test both the bag and the beaker for presence of glucose. . Record all data in table. Lab 1b allnurses obtain the six strips of dialysis tubing and fill each with a solution of a different molarity. .
cell is in a hypertonic solution is called plasmolysis. During these experiments, it will be proven that diffusion and osmosis occur between solutions of different concentrations until dynamic equilibrium is reached, affecting the cell by causing plasmolysis or increased turgor pressure during the process. Materials: Lab 1a to begin, lab 1A, first collect the desired equipment. . The materials needed are dialysis tubing, iodine potassium Iodide (IKI) solution, 15 glucose/ 1 starch solution, glucose testape or Lugols solution, distilled water, and a 250-mL beaker. Lab 1b for, lab 1b you will need to collect six presoaked dialysis tubing strips, distilled water;.2M,.4M,.6M,.8m, and.0M sucrose solution; six 250-mL beakers or cups, and a scale. Lab 1C these items are needed: a potato, knife, potato core borers, six different solutions, and a scale. Lab 1d during, lab 1d, only paper, pencil, and a calculator will be needed to make the calculations.
If the solutions differ in concentration, the area with the higher solute concentration is hypertonic and the area with the lower solute concentration is hypotonic. . Since a hypotonic solution contains a higher level of solute, it favourite has a high solute potential and low water potential. . This is because water potential and solute potential are inversely proportional. . A hypotonic solution would have a high water potential and a low solute potential. . An isotonic solution would have equal solute and water potentials. . Water potential (y) is composed of two main things, a physical pressure component, pressure potential (yp and the effects of solutes, solute potential (ys). . A formula to show this relationship is y. . Water will always move from areas of high water potential to areas of low water potential. The force of water in a cell against its plasma membrane causes the cell to have turgor pressure, which helps maintain the shape of the cell. .
Osmosis and Diffusion Lab Report Introduction All Cells
Lab 1, osmosis diffusion, cells have kinetic energy. . This causes the molecules of the cell to move around and bump into each other. Diffusion is one result of this molecular movement. Diffusion is the random movement of molecules from an area of higher concentration to areas of lower concentration. Osmosis is a special kind of diffusion where water moves through a selectively permeable membrane (a membrane that only allows certain molecules to diffuse though). Diffusion or osmosis occurs until dynamic equilibrium has been reached. . This is the point where the concentrations in both areas are equal and no net movement will occur from one area to another. If two solutions have the same solute concentration, the solutions are said to be isotonic. .
