Characteristics of Life

Over the next few days, until our Test on Friday or Monday, we’ll be studying the 8 characteristics of life. You should know the description of each, any vocabulary associated, be able to provide an example, and assess how each characteristics relates to the others.

  1. Cells
  2. Metabolism
  3. Reproduction
  4. Homeostasis
  5. Evolve
  6. Heredity
  7. Respond to Stimuli
  8. Growth/Development

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 tomorrow for Biology

First Day of School 2017!!!

I know… I feel the same way.

Welcome to Mr. Kubuske’s Class! First, please add this link to your home screen (If you do it right, you should see a picture of your new favorite teacher smiling at you right from your iPad). 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 a few 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. Yes, a separate binder just for Science. Trust me, I’m helping you out here. You must have the binder by Monday! This is your 2nd assignment of the year.

Once you have the papers you can complete the assignment titled Biology Procedures Activity that you picked up from the front table. This, in case you were wondering, is your first assignment of the year.

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. Please, please, please come by and visit next year and see what the new freshmen are up to, or if you need help with a little chemistry.

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!

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)

Climate Challenge

Yesterday we talked about Human impacts on the environment. We covered several topics including:

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

Today we’ll be reviewing some case studies to determine the cause and solutions to some of these problems. 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

What did a T-Rex Taste Like?

trexWhat did a T-Rex Taste Like?

Believe it or not, we actually have was of finding this answer despite the fact the Tyrannosaurus Rex has been extinct for over 65 million years. We can determine a T-Rex features, including taste, using similar features (which we now know are called homologous structures). shared with animals the T-Rex is closely related to.

Recall that yesterday we learned that the more features you have in common, the higher the probability that you share a common ancestor/DNA (the exception would be convergent evolution where two species become increasingly similar despite the fact the originated from different ancestors). So what we can do is plot relatedness, based on characteristics, on a graphic called a cladogram, like the one shown here.

 
So Today, that’s exactly what we’ll be doing, using the link at the top of this post, you’ll follow the steps to learn how cladograms are created, organized, and what the different branches of it mean. By the time you are through, you will know what it tastes like to bite into a big fat dino-burger!

Evolution Simulation

Sorry I can’t be there today. But I’ve got two great activities for you while I’m gone.

First, do the Darwin “Scenarios” activity with the people at your table.

Then, in our previous class we played a game using Darwin’s theory of Natural selection to see if we could help a fictional species last for a million years. There were environmental factors that influenced change, and ways of adding variation to a population.

Now we can take what we have learned and actually apply it to a real evolution simulation. We obviously cannot make evolution happen in a lab, but we can simulate it using Darwin’s theory. Click the link below (iPad users must be in the Puffin browser, not Safari) to be taken to the simulation. Read the directions, follow the procedure I have provided, collect your data, and graph your results.

Simulation

Watch how small changes in populations can have big impacts. You can also change settings to see how these animals would fair when their food source behaves differently.

Common Assessment #3

Common Assessment #3 – Link

Tomorrow we’ll be taking the 35 Question Common Assessment for the third quarter. It will cover Unit 7 (Reproduction) & Unit 8 (Genetics). The study guide is available on the Semester 2 Documents page, or you can get it from the link below. The key is also available for viewing this afternoon.
