PHY 121 College of DuPage Motion Forces & Vectors Report
Quick OverviewQuick OverviewThe portfolio project is where you get to show off what you can do with physics. So far we've learned Forces & Vectors so that's the focus of this portfolio.At home, you'll set up one or two scenarios (details in instructions). You'll measure everything you can about those scenarios and use those measurements to do calculations and show off your physics skills. A scorecard gives you a list of measurements, calculations and skills that you can choose from. Finally, you'll present all those measurements, calculations and skills in a presentation. This can be a video, a powerpoint, a word document, a sway, a webpage, a padlet...you get to choose your favorite platform.Read all of these tips before getting started and read them several times again as you work. :)Video Intros and Instructions for the Portfolio ProjectFirst here is a video in which I explain my philosophy of assessments and why I picked a portfolio project.Now, here are the instructions for doing the 1st Portfolio.Who and What Are You Allowed To Work With?Who and What Are You Allowed To Work With?You are expected to finish the portfolio by yourself. Do not do the scenarios with other people and do not share your own results. This is the equivalent of a take-home test where your work is your own.You are allowed to use all our notes and videos on Blackboard to help you as you go. You can also use the textbook and your old Connect work. Do not use other students in the class.If you are stuck, reach out to the professor, she is so happy to helpProfessor Graessle's ScorecardYour scorecards will be different - this is one from late in the semester. Also the point levels will be new each semester, depending on what the class votes for the category percentages.When You Turn Things In...When You Turn Things In...Turn in your project and turn in your Scorecard each time. This will help me grade it - if you tell me what points you are going for, then I know what to look for. Makes sense, right? Thanks!If you do a video or Padlet, please post a link to your video in YouTube or your Padlet along with your scorecard. Please do a new Padlet for each portfolio (but within one portfolio, you can do more than one scenario). Do not edit your padlets or videos after the due date! To be safe - don't even load up your Padlet after the due date until you see a grade for it in Blackboard. If you are making a Powerpoint, please use just black and white background - don't get fancy. Fancy = large filesize = may not upload = MONSTER AMOUNTS OF STRESS. Thanks!Upload your portfolio with plenty of time for possible technology glitches. I recommend finishing a day or two early just in case you can't get the files to upload and you need Professor's assistance!FAQ SectionFAQ SectionHello! Here's a helpful FAQ section for you! Right now it's based on questions from past sections but I will add new FAQs from you as needed. Check back here often :)1) I found coefficient of friction by...(doing something different than what was done in the sliding book video). Is that ok?No, that is not ok. The way the scenarios are set up, if you are finding coefficient of friction by methods other than outlined in the sliding book video, something is going wrong.2) What do I measure?Right now, the only official measurements we are doing are angle, coefficient of friction and mass. That's all you need, believe me!3) How do I start?Check out our physics problem-solving strategy! It's really great for portfolio help. First explore your scenario and make measurements. Second, set up a diagram. Third, set up your equations that go with the diagram. Fourth, solve for everything you can from those equations. Fifth, maybe there's other things you can figure out (see the scorecard for things you haven't found yet and maybe you can figure out those, too!).4) Is it ok if I tilt the table in scenario 1? May I make the masses the same in scenario 1? May I make the table flat in scenario 2? Can I change the scenarios from how they are written?No - this is a really bad idea. You won't get any points for a scenario that isn't what was presented. See the instructions video for setup ideas. Again, if you tweak a scenario you will not get any points for that work.5) Is there an applied force from the hand in scenario 2? Yes.6) Can I do both scenarios? Or...do I have to do both scenarios?Sure! You can do both - solve for everything you can! If there's doubles, there's doubles - you get credit only once but think of it as insurance. If you've found that one scenario doesn't give you enough points, then for sure hop over and add the other one in. 7) Can I get more than 150 points?There are a lot more than 150 points possible on this portfolio. If you get more than 150 points, your score will stay at 150. I do recommend that you try for 160 or more points, though, just in case you make a mistake! It's physics, mistakes happen a lot. :)Still Nervous About Coefficient of Friction? Read This!Still Nervous About Coefficient of Friction? Read This!Hello, scientists! A lot of people are emailing me, nervous about figuring out coefficient of static friction. Mainly that, to find it, you need to tilt a surface - but the first scenario is not tilted. I totally validate your confusion - you've never measured coefficients of friction before and you want to get it right! Okeedokee, so here's my hint: To find coefficient of friction, you will have to take the object on the table and the "table" itself and run a quick side-experiment. Then, whatever coefficient you get from that side experiment, use it for that scenario. Because there's only one coefficient of friction between 2 objects. It doesn't depend on tilt. Yup!The coefficient of friction you get from running that side experiment IS the coefficient of friction for that scenario! :) :) :)Keep letting me know how else I can help. Great work!Portfolio 1 - Upload Here!If your portfolio is a powerpoint, a pdf, a word document or jpg images:Upload your portfolio and scorecard here, just like you've uploaded any other file before. If your portfolio is a Padlet:Upload your scorecard here and also write the link to the Padlet in the comment box.Do not log into your Padlet again until I've graded it - Padlet will tell me you've edited your work after the due date and you do NOT want that, because I'll be marking your Portfolio Late and taking away points.This is set up with infinite uploads in case you want to upload multiple files or find a mistake and want to upload fresh. I’ll grade the latest copy of each document.

Grossmont College Mitosis and Development Lab Worksheet
NOTE: Please use Basic English language/ Common language just like last time. NOTE: Try to make your answers short and neat "no long answers because the professor will not approve"Refer to the laboratory models and charts, your slides, or your textbook's diagrams of the mitotic phases in plants. In the spaces below, make realistic rough sketches (not cartoons) of each stage of the cell cycle (including interphase) as one onion root tip cell divides into two daughter cells.Make diagrams here:List the main actions that happen during this phase here. Use arrows and words to label important parts:Prophase:Metaphase:Anaphase:Telophase:Interphase:Table 1. Number tally of onion root tip cellsin different phases of the cell cycle Group TallyOther Group CountsClass TotalPercent of TimeClass Avg.InterphaseXxxProphaseXXXMetaphasexxXAnaphaseXXXTelophasexxXTotal CellsXXX Calculate the percent of the cells' total cycle time spent in each phase using the following formula:percent of time spent in phase = Record the values in Table 1 and in the class data table on the board. Question 1. Based on your calculations which phase plant cells spend the most time. Be able to explain why.Question 2. Why is a class average more likely (than your group's data alone) to reflect the truepercentage of time spent in each phase?Question 3. Using the class averages for each phase (Table 1, previous page), draw a "pie chart" to graphically demonstrate the relative amount of time an average onion root tip cell spends in each phase of mitosis:Using the whole "pie" below to represent 100% of the cell cycle time, sketch in "wedges" which reflect the portion of the pie (relative percent of time) spent in the different phases by the cells in your onion root tips. Figure 3. Pie Chart: Relative Amounts of Time Spent in the Various Phases of Plant Mitosis Question 4. Compare your chart with a general pie chart for plant mitosis found in your textbook or some other reference. Describe the similarities and differences. Question 5. Speculate on why our class' pie chart percentages may not agree exactly with those seen in your reference. Question 6. Are the aboral (top side) and oral (under side) surfaces similar? If not, how do they differ?Question 7. Closely observe the flat oral surface. Locate the main opening in the center, surrounded by the five-pointed star-like structure. The star-like structure is often difficult to see in a sand dollar as it covered by many of the moveable spines. However, this structure is much more easily seen in a relative of the sand dollar, an urchin. View the following video to observe this structure. https://www.youtube.com/watch?v=hLg4EbxWqNo (Links to an external site.) What is this structure’s function?Question 8. Observe the following short video: Video”A Sea Biscuit’s Life) 3:36 minutes https://www.youtube.com/watch?v=KeIvSE5S2yQ (Links to an external site.)Use the above Video to answer questions 8, 9, 10, and 12.Above is a Sand Dollar Egg, notice the difference between it and the Sea Biscuit egg (35 seconds into the video). What do you see as the major differences between the two species?Question 9. Describe the sperm movement (31 to 33 seconds in video). Does it appear to be directed or random? Question 10. In the spaces below, briefly describe the form (shape) of an egg and a sperm. Then describe the mobility(movement), if any, of the two kinds of cells. Now compare the gametes' sizes(make sure you are viewing them both at the same magnification). SpermEggFormMobilitySizeSuggest a possible explanation for the observed differences. Question 11. Surrounding the egg cells, you will notice a protective gelatinous material containing colored granules. This material is outside the cell membrane of the egg. (Label this material in the image labeled Unfertilized Egg in Figure 4.)FertilizationQuestion 12. It is usually not possible to observe fertilization (nuclear union) but you can tell when it has occurred, for a fertilization membrane (40seconds) will develop around each fertilized egg, inside the egg’s gelatinous cover. (Label this on the image of the Fertilized Egg in Figure 4.) This halo-appearing membrane emerges from the surface of the cell and signals the formation of the zygote. Draw a fertilized egg showing the fertilization membrane. What might be its function? Question 13. Draw arrows between each of the stages in Figures 4 and 5. Then on the top of the arrow, label what process is happening (formation of fertilization membrane, first cleavage, etc.) based on what is listed in Table 2 below. On the bottom of the arrow, label how long the process takes (e.g. 2-5 minutes, etc.). See the example on Figure 4.Question 14. On entering the egg, the sperm nucleus carrying the male chromosomes unites with the nucleus of the egg to produce a zygote with the chromosomes of both egg and sperm. What is the relative chromosome number of the zygote compared to the gametes? THINK! Question 15. Were the photographs of all the stages up to gastrulation pictured in the video of the Sea Biscuit seen earlier taken at the same power magnification?Within individual stages in the early cleavage stages, how do the individual cell sizes compare?How does the size of the entire cell mass compare at these different stages?Question 16. Find the mass of cells called a morula (1:22 in the Video) and on figure 5 Draw the morula. Be sure to label it as a solid sphere of cells.Question 17. Draw a blastula (only seen in Figure 5). Be sure to label it as a hollow, fluid-filled sphere. Question 18. Compare the size of a blastula to that of an unfertilized egg. Has the embryo actually grown? Estimate the number of cells the blastula contains:Question 19. Describe how you tell if an embryo is a simple mass of cells ("morula") or actually a blastula (fluid-filled sphere of cells). Question 20. Draw a gastrula. Label the ectoderm and endoderm (using arrows to point to parts).Question 20. A gastrula will develop into free-swimming "pluteus" larvae (1:34 minutes) in a day or two. In contrast a sea star forms a bipinnaria larva. What does gastro- (as in gastrointestinal tract) mean?Questions 22. At what point in development would you logically expect the larvae to be capable of growth (growing in size)? Explain your answer.Review of Sand Dollar DevelopmentAnswer the following questions with reference to the letter designations in the chart below.ProcessesStagesa. fertilizationf. larvab. morphogenic migrationg. gametesc. hatchingh. blastulad. cleavagei. zygotee. metamorphosisj. gastrulaQuestion 23.
