IB BIOLOGY: Week 1 - Plants and Review week 1 (4/20-4/25) So here’s what the next/last six weeks of the year will look like: 2 weeks to finish plants, 2 weeks of reviewing the big important concepts, and 2 weeks for a final project. Before any of this can happen, I need you first and foremost, to make and register a personal google site, on the google form I posted to the website. This site is where you will display ALL of the work that you will be doing each week. Please make sure that your site has full permission to let anyone view it, when it is published. Here is where you should register your website if you haven't done so yet: https://forms.gle/FCAmRJy79EUeqVmy5 Once you have created your website, I will ask you to make specific pages and your goal is to make this information easy to understand so please be aware that your spelling and grammar play a BIG role in making that happen. For this week, now that you have created and registered a website I need you to create two pages on that site that MUST be titled “Xylem” and “Phloem” The following lists are what should be included on each of these pages, and as you add photos, videos, drawings, etc. to demonstrate the following concepts, I would like you to try and create REAL photos of your own to demonstrate the concepts. You can pull weeds out of the ground to show general plant anatomy (Highly recommended.) You can use vegetables from the kitchen. If you cannot take a picture to show anything you are discussing, such as very small structures, feel free to use micrographs from online, but be sure to cite the source (in text) underneath any photos. On the webpage titled “Xylem,” Please show the following concepts in any order you choose. Transpiration, and its connection to water transport in the plant. The role of cohesion and adhesion in water uptake. The active uptake of minerals to induce osmosis in roots. Include a detailed longitudinal illustration of xylem vessels. (Yes, this must be a drawing using pen and paper (take a picture for your site) or Google draw.) Be sure to show what role lignin plays in this structure/ Include a section to show (text and illustration) at least one adaptation of desert plants that helps them retain the water they absorb. Create one analogy that could help someone understand the whole process of water uptake through xylem tissue. Please use a giant redwood tree (Sequoiadendron giganteum) as your example since people are always amazed that water can get to the very top of these very tall trees. Bonus (not required): Celery Experiment: https://untamedscience.com/biology/plants/water-transport-experiment/ Give it a try and post your results. Resources: https://ib.bioninja.com.au/higher-level/topic-9-plant-biology/untitled/xylem-versus-phloem.html On the webpage titled “Phloem,” Please show the following concepts in any order you choose. Explain what “sources” and “sinks” are in plant transport. to sinks. How does phloem tissue “load”?. What connection does phloem play in water uptake in xylem? Think osmosis. How does hydrostatic pressure play a role in phloem transport? (incompressibility). Include a detailed illustration of phloem sieve tubes, companion cells, parenchyma cells,and fibers and how they function together. (Yes, this must be a drawing using pen and paper or Google draw.) Research, describe, and show the method used for measuring phloem transport using radioactive CO2 and aphids. Create one analogy that would help someone understand the whole process of product transport through phloem tissue to feed a plant Resources: https://msu.edu/~walwort8/page2.html https://ib.bioninja.com.au/higher-level/topic-9-plant-biology/untitled/xylem-versus-phloem.html Bonus (not required): Bug Poop Video: https://www.youtube.com/watch?v=LVdynVuJsBo Add this to your page and explain the role of osmosis in the plant/aphid interaction. Show me you know how osmosis works. Once you have completed your two pages you need to do nothing else. I will check your work first thing on the following Monday morning by looking at your website. If you did not open the permissions to your site you will receive a zero for this week's work. If you need help with anything, I will be available online from 8-12 on Wednesday on zoom (https://zoom.us/j/99042145983?pwd=M2tOT0tycG1zODgyYkEwNzhObU42UT09), and am available from 10-12 on Thursday and Friday. If you would like to zoom, Google Meet, video call, text, email, etc. please contact me and I'll set it up. If you need help outside of these hours, please just text and I'll work it. EARTH DAY is TODAY the 22nd of April !!! The same day as when your science work comes out!!!! While I have spent the last 20+ years going to Balboa Park on the weekend and meeting up with students, it obviously won't be happening this year. Instead, IF YOU WANT SOME EXTRA BONUS KARMA, make a video that is 30 second or less on what you love about "Mother Nature" and how much you miss it. You can do it as a skit. You can include family members. You can make it into a funny commercial. Be creative. Send as an attachment on an email. Biology and Community Health: Week 1 - What is in an ecosystem? (4/20-4/25) Before we get started, first and foremost, make and register your personal Google website where you will display ALL of the work that you will be doing until the end of the year. I've also made a screencast of how to do this below to help you. Please make sure that your site has full permission to let anyone view it, and is published. Here is where you should register your website if you haven't done so yet: https://forms.gle/FCAmRJy79EUeqVmy5 What’s the long term goal? Over the next 4 weeks you will be asked to create a dynamic and exciting website for one of four real African preserves that would attract biologists to come from all over the world to visit this unique ecosystem. Each week you will add new components to this website, and it will be checked on a weekly basis to see that you have completed what must be done. For this first week of website construction, you will be registering with a real African research project that uses camera traps (https://en.wikipedia.org/wiki/Camera_trap) to take pictures of animals. They usually take three photos to show movement (SO DON'T FORGET TO HIT THE PLAY BUTTON AT THE BOTTOM) These photos are used to determine how many animals (and the ages) the park has (population), and what the animals are doing with each other (community), so the rangers can manage the park better and keep the whole park system (ecosystem) healthy. Because so many pictures are taken of so many animals, a few park rangers can’t keep up. This is why the rangers post them online looking for help from people like you. Once you register with the appropriate website, there will be a tutorial on how to identify the animals in the photos, and then you will start to classify them using the pictures. I've also made a screencast of this below to help you. Some people get worried that they will do it wrong. Don’t worry, many other people will look at the same pictures that you looked at, but it’s the rangers that will make the final decision. So, if a picture or two aren’t quite right, someone will fix them. Please note that your classifications are REAL scientific data that you are helping collect. This is all called citizen science and is very important to many areas of research. So, which African preserves will you be promoting over the next 4 weeks? Well, that depends on the period you are in and the first letter of your LAST name, as each of you will be doing only one of four possible African preserves. If you are in Period 3 and your LAST name starts with A-E, or if you are in Period 5 and your LAST name starts with A-G, you will register for Karoo. (DON'T FORGET TO HIT THE PLAY BUTTON AT THE BOTTOM OF EACH IMAGE) https://www.zooniverse.org/projects/shuebner729/snapshot-karoo If you are in Period 3 and your LAST name starts with H-K, or if you are in Period 5 and your LAST name starts with H-K, you will register for Grumeti. (DON'T FORGET TO HIT THE PLAY BUTTON AT THE BOTTOM OF EACH IMAGE) https://www.zooniverse.org/projects/meredithspalmer/snapshot-grumeti If you are in Period 3 and your LAST name starts with L-N, or if you are in Period 5 and your LAST name starts with L-R, you will register for Gorongosa. (DON'T FORGET TO HIT THE PLAY BUTTON AT THE BOTTOM OF EACH IMAGE) https://www.zooniverse.org/projects/zooniverse/wildcam-gorongosa If you are in Period 3 and your LAST name starts with R-T, or if you are in Period 5 and your LAST name starts with S-Z, you will register for Cambedoo. (DON'T FORGET TO HIT THE PLAY BUTTON AT THE BOTTOM OF EACH IMAGE) CAMBEDOO RAN OUT OF PICTURES TO CLASSIFY !!! If you did not get to this one, work with this project instead: South Sudan: https://www.zooniverse.org/projects/southsudanwildlife/south-sudan-diversitycam All of these four parks/preserves are found in Africa and have amazing biodiversity (meaning they are healthy environments and have many different forms of life). Yet to understand how it all came about we must look at the geology, the seasons, it’s location on Earth, etc. This week we will focus just on looking at the pictures from the camera/photo traps and graphing that data to get an idea of how many and what kinds of animals exist in your park. (DON'T FORGET TO HIT THE PLAY BUTTON AT THE BOTTOM OF EACH IMAGE) What will your work look like at the end of this week? Create a landing page on the website you registered with me that is titled “(Your Park)” and is attractive, then create another page titled “Biodiversity” that displays a bar graph of your animal data that will show the biodiversity of your park. I've also made a screencast of how to make a graph below to help you. Where does the animal data come from? It comes from your work on the websites you registered for. As you make identifications of the animals, record the type and number, and maybe even take some screen shots of the animals. When you have made 50 or more identifications (after the tutorial), you will make a bar graph (with a proper title and labels) of the animals you found and present it on the “Biodiversity” page with at least 2 pictures of the most common animals found there and 2 of the least found animals in the park according to your graph. These pictures could be from your screen shots (if you took any), or they can be found online, but be sure to cite the ones you found online. Non-cited pictures will not be counted. Lastly, please make sure you use the terms population(s), community, and ecosystem in describing your graph. Remember: If you need help with anything, I will be available online from 8-12 on Wednesday on Zoom (https://zoom.us/j/99042145983?pwd=M2tOT0tycG1zODgyYkEwNzhObU42UT09), and from 10-12 on Thursday and Friday. If you would like to zoom, Google Meet, video call, text, email, etc. please contact me and I'll set it up. If you need help outside of these hours, please just text and I'll get right on it.
