Lab Safety… it’s no Accident

Today we’ll be going over some important information about your safety in a Lab setting. After review the Lab Safety rules (check the documents page for your specific class for a PDF version), take a look at the image below. See if you can spot some incidences of failing to follow lab procedures for safety.

Reminder there will be a “Common Sense” Lab Safety Quiz!

First Day of School (ok, the cycle)!

I know… I feel the same way.

Welcome to Mr. Kubuske’s Class Blog. First, please set a bookmark or a link to your home screen. After that feel free to browse this page. At the top are links to class pages where notes, assignments, and documents will be posted for you to download as we work through our curriculum. There’s a page for students, a page about Mr. K, and other resources available. On the right (or bottom if you are using Safari on the iPad) are links to my twitter and other information that will help you.

Next, there are 3 papers on the front table I’d like you to pick up. You will need to keep these papers all semester so put them in a safe place. Eventually, these papers will need to go in your Class 3-ring binder.

Once you have the papers you can complete the assignment titled “Biology Procedures Activity” that you picked up from the front table.

As a reminder, you will need to download your iBook at home or in a place where you can be on a wifi network for a long period of time.

Thanks for participating and we look forward to working with you this year!

All Good Things Must Come to an End

Thank You, Thank You, THANK YOU for a fantastic school year. I had so much fun with each and every one of you. I loved getting to know you, what makes you tick, what inspires you, how you learn best, and so much more! My hope is that you got as much out of learning with me as I got from teaching with you. As a final gesture of goodwill, please take a second to fill out the form below to help me make this class even better than it has been. Have a fun and safe summer and I’ll see you next year!

Are You an Energy Master?

Before we take our Energy Quiz, lets see if you have what it takes to be called a Photosynthesis or Cellular Respiration Master! Click the links below, download the attached powerpoint, open in keynote and play the presentation. As you go through, click the appropriate boxes and answers to questions. If you can successfully get through the whole thing with no wrong answers, you are ready! Take as much time and as many tries as you need! Good luck!

Photosynthesis Master

Cellular Respiration Master

Cellular Respiration

Cellular Respiration, although the inputs and outputs seem easy, the process is very convoluted and complicated. Lucky for you, we’re going to simplify it to a point that is appropriate for a High School Biology student.

Keep in mind that Photosynthesis & Cellular Respiration are reciprocal reactions. What that means is that the requirements of Cellular Respiration are the products of Photosynthesis! Likewise, the products of Cellular Respiration are the requirements of Photosynthesis! Its a 3 Billion year long symbiotic relationship! (And you thought your month-long high school girlfriend was a long-term commitment!)

Here is the jist of what Aerobic (meaning with Oxygen present) Respiration entails…

 

Aerobic Respiartion

Glycolysis

  • Uses 2 ATP to break down Glucose
  • NADH & 4ATP (net gain +2 ATP) are created.
  • The NADH goes to the Krebs Cycle.

Krebs Cycle

  • Uses Oxygen and Acetyl-CoA
  • Makes 2 ATP, NADH, & FADH2 (both of which are electron carriers)
  • Carbon Dioxide is given off as a byproduct.
  • The NADH goes on to the ETC

Electron Transport Chain

  • Uses Oxygen and NADH
  • Make 32 ATP and Water (used as an electron acceptor)

Photosynthesis

Photosynthesis may seem like an easy topic, based on what you learned in middle school. But, as we go a little deeper into the processes of how Plants chemically create glucose from a gas, a liquid, and sunlight we find that it is a whole lot more interesting and complicated. Below is a graphic organizer to show the parts of the chloroplast, the reactants, the products, and the important molecules involved in both the Light & Dark Reactions.

Photosynthesis14

Light Reaction

  • Light & Water enter the Thylakoid (or granum)
  • Oxygen is released as a byproduct
  • In the process, NADPH and ATP are charged and carry energy to the Dark Reactions.

Dark Reactions

  • The ATP and NADPH, combined with Carbon Dioxide, create Glucose.
  • The leftover NADP+ and ADP go back to the light reaction.

Once you think you’ve Mastered all there is to know about Photosynthesis, try your hand at this game: Photosynthesis Master. Open the document in Powerpoint or Keynote, start the presentation, then click on the boxes with the correct answers to the questions. See if you can make it all the way through without a wrong answer… if you can you will be the Photosynthesis Master!

Ch-Ch-Ch-Changes… in the Environment

Yes its true Mr. Bowie (RIP), the only constant in life is change. The same goes for our environment. Forests didn’t just magically appear, and the great swamps that covered much of the midwest at one point didn’t either. Change occurred in slow and dramatic fashion. Today we’ll be learning about three different types of changes that occur in environments and, good news, this is the last section of our Ecology unit. Those changes are known as:

  • Primary Succession
  • Secondary Succession
  • Eutrophication

Below is a brief (less than 5 minutes) overview of these changes. What I’d like you to do is to 1. take the notes and 2. take a sheet of paper (preferably the one you picked up when you came in), turn it landscape (so that it is wider than it is tall) draw the images shown in the presentation when instructed. When you’re finished there are some review question to cover as well.

Here is a great example of Secondary Succession:

As a reminder, tomorrow in class our lab will require the use of open flames. So please no loose clothing and be prepared to tie your hair back.

Climate Challenge

Today we’ll be covering human impacts on the environment and discussing the ecological case studies we read about last week.  We’ll cover several topics including:

  • Acid Rain
  • Ozone layer depletion
  • Mass Extinction
  • Depletion of Natural Resources/Destruction of habitat
  • Climate Change
  • Invasive Species

After that, we’re going to play a game courtesy of the BBC. The game is called “Climate Challenge” and basically you get to run a country that is facing the threat of global climate change head on. You’ll have to balance protecting the earth, your citizens, and your job! Use the link below to reach the game (*note, if you are using a iOS device you will need to view this using the puffin app). Good luck, have fun, and learn something!

Climate Challenge – The Game

Evolution Review!

Greetings from the campus of THE Ohio State University in beautiful Columbus, Ohio! That’s where I’ll be today. But I believe you’ll do a great job without me today. You’ve done a great job with the graphic organizers and it’s amazing to see how much content yo have picked up and recalled because of it! It’s a lot to cover but you’ve done it and done it well. Today I’d like you to:

  • Finish your illustrations
  • Add as much information to your board as you can (keep it neat and near the topic on the organizer)
  • Complete your video and email it to me(time-lapse or narrated). You may want to add background music for effect.
  • Complete the info-search you picked up in the front of the room (you can do it by yourself, with your table, or as a class… your choice)

Use the graphic organizer you created on Monday as a study guide this weekend. Remember you Unit 9 Group test is the first day back from Easter break, Tuesday the 29th! It will be some multiple choice but mostly fill-in and short answer. Have a great Easter!
