Tuesday - Minimum Day
IB Biology - Today we had a chance to meet again! It was so good to see you all, and to meet some new faces. We played a game that dealt with trying to figure out a pattern of cards. You may or may not have been able to do that, but what is more important is that you had a method. Tonight, the first thing I want you to do is to use the piece of paper you had in class and to describe what your method had to do with science. We will be discussing this in class tomorrow so be prepared. Hint: Have you considered evidence, error, statistical significance, null hypotheses, etc.?
Once you have done this I need you to spend some time on the website looking around at the many features I have to help you in your journey. Be sure that you read the "About" page, and definitely the "Lab Guidelines." At the bottom of this last page (Lab Guidelines) is a survey I need you to complete. this must be tonight and constitutes an agreement that you understand all of the requirements of my class.
You should also put something down on your planner about getting the materials needed for this class.
Honors Biology - Today it was a pleasure to meet you all! This class is going to be a challenge, but if you are willing to engage it will be fun.
Tonight I need you to spend some time on the website looking around at the many features I have to help you in your journey. Be sure that you read everything, but especially the "About" page, and definitely the "Lab Guidelines." At the bottom of this last page (Lab Guidelines) is a survey that I need you to complete. This must be done tonight and constitutes an agreement that you understand all of the requirements of my class. Please come prepared with questions about the website or my class, if something isn't clear as I want you to be prepared for everything we do.
OH, You should also put something down on your planner about getting the materials needed for this class.
IB Biology - Today we had a great day starting out with a challenge for our first unit on cell biology. In this conversation I told you that I want to be able to see cells and their ultrastructures, and as we worked through this challenge we dredged up the pieces of cell/tissue observing that we already know. The following list has the kinds of things that should be considered when designing a lab to demonstrate cells and their structures: cell size, parts, cell types/tissues to use, what are cellular structures made of, how to use a microscope, how to make solid IB illustrations, and what are appropriate stains? You then got into your groups and decided who would handle each part of this work that will be due by the end of next week. So tonight you need to come prepared with at least idea of how to attack the part that you are responsible for.
Honors Biology - I feel good about today because we had a chance to clarify all of the class information. You should know where to find your assignments, how you will be graded (and why I use rubrics), lab safety guidelines, and how to complete the survey that many of you still need to do. If you have not completed this survey, this is your night to do that.
The next things we did in class was to organize you into your lab groups and we discussed the nature of science. We learned that science is not just about a method, but has financial, ethical, and cultural effects. We learned that no how much data you have, you just can't have too much! We learned that in science we can more easily talk about probabilities than in absolute truths. You then thought about these and made a list based off of the sentence starter, "In doing science there are 4 things you should always know: ..."
Tonight I want you to use the second sheet of paper we set up that was titled, "How to find out how far a 9th grade student can jump." Under this title I want you to make a set of clear instructions on what steps you would take to answer the question I gave you. These should be step by step, and be a procedure that we can conduct in class. You will be turning this in to me first thing tomorrow!
IB Biology - Today you spent a chunk of time figuring out what you know and what you still needed. I addressed your questions and I tonight I want you to come prepared to put things together. We discussed the need for an explanation that should accompany your illustration. We talked about your illustration guidelines and that it should have scale shown. The following is a resource for IB illustration guidelines. https://i-biology.net/2012/05/06/command-terms-drawing-skills-for-ibdp-bio-exams/
As we had into tomorrow and our work you should also know that by Monday you will need to use you BOOKS and have a 5 subject notebook to collect all of your work! Inside your book there are tips on how to calculate scale, what are the structures in cells, microscopy with light microscopes, etc. Have your text and your freshman year bio notebook handy and ready to go. You may stash them in the room.
Honors Biology - Today you continued to distill the ideas on the "nature" of science. You worked in new pairs, and then in your lab groups. Some of the great things I heard were that you neededdifferences to be specific in your actions and inquiries (questions), and that you can never have too much data/evidence! Next you designed an experiment by looking at what we created last night as individuals and critiquing (reviewing) what was good and bad about what we had though up.
Lastly, if your class got to it, you then collected data for processing tonight. Period 3, you got to that point and you can find your data below. These numbers should be on their own sheet of paper that we started in class and should show your calculations. Please be ready to process it again tomorrow. If you are period 5, please be prepared to strip off your shoes and socks so you can follow your instructions and collect data by jumping tomorrow!
IB Biology - So, while today you continued to address our initial project of showing and explaining the ultrastructure of a cell, drawing them to scale, and producing slides to support your points; you now should have your textbook to draw information from as well. This means we'll start to get into the content that you need to focus on. Your first assignment that uses this book deals with the origins of cells. I want you to report what the book says about cellular origins. You should also include an explanation of the endosymbiosis theory. Now that you have done this, I need you to also research two other evidence based theories of cellular origins. Cite your sources in APA format. Next, using these three ideas, I want you to compare (look at similarities) and contrast (look at differences) these ideas. Lastly, I want you to evaluate which idea you feel is best supported by evidence.
Here's a resource for scale drawings: https://www.thinkib.net/biology/page/17083/calculating-magnification-and-size

Honors Biology - Today we started the process of analyzing our data. We looked at average, mode, median, and some easy tricks we can do using Google Sheets. Yet we realized that these numbers don't really tell the whole story, there's more that the data can tell us. For instance, could height have played a role in all of this? So, we collected the heights of all of the jumpers and created a scatter plot to see if there was a trend (using a trendline function from the "series" tab on chart customization). I am only asking you to print up your raw data (numbers) and graph (1 sheet) and jot down at least three things that our analysis tells us. This should be a deep thinking activity and when you jot down your ideas they should be in the form of statements that are supported by the data. OH, DO NOT FORGET TO HAVE YOUR NOTEBOOK BY MONDAY. WE SET IT ALL UP THEN!
