Theories of Evolution

That’s what we’ve been talking about the last few days. We’ve talked about theories and evidence that supports or refutes those theories. There have been lots of theories of evolution but we’ve focused on two…

  1. Jean-Baptiste Lamarck

    • Acquired Characteristics
    • Whatever traits or habits that you picked up over your life, you passed on to your children.
    • Believed that if you really “needed” something or some habit to survive you could acquire it.

  1. Charles Darwin

    • Descent with Modification – Present living beings are modified decendents of older organisms and species.
    • Modification by Natural Selection – Environment limits the growth of populations. Some Organisms have traits that make them better able to survive in their environment

Evidence suggests that Drawin’s theory, which he illustrated in his book “On the Origin of Species”, is accurate. Can you think of any instances of organisms that look like other species but have some type of special advantages to help them survive in their environment?

To review, click through the Darwin information pages and see if you can help a species of furry creatures live for a million years!

Origin of Eukaryotes

Yesterday we discussed prokaryotes; their characteristics and examples. Today, we’ll examine the eukaryotic cell and its characteristics. But, before we do, lets take a moment to theorize where Eukaryotes evolved from 1.5 billion years ago.

For today’s warm up, do the “Endosymbiosis” worksheet

Key ← Use it as a resource, not to copy

Then we’ll be taking some time to learn the parts of a Eukaryotic cell. Please watch the YouTube Video or open the PPT in Keynote to complete the “Cell Part Chart” in a paper format or as a PDF.

In our next class, we’ll review the types of cells as well as this chart and the parts of a Eukaryotic cell.

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!

RNA & Transcription

Today in Biology we’ll start our last Unit of the semester… Protein Synthesis. Protein Synthesis is sometimes referred as the “Central Dogma” of Biology, meaning its the key idea. The key idea of protein synthesis is that DNA codes for our traits and that code is used to create proteins that actually are our traits. All other parts of biology either exist because of, or are incorporated with Protein Synthesis.

There are two major parts of protein synthesis:

  1. Transcription: Using DNA → to make RNA
  2. Translation: Using RNA → to make Protein

Today we’ll be focusing on Transcription and the stuff it makes, RNA.

First Day of School (ok, the cycle)!

I know… I feel the same way.

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.

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

The DNA (web quest) Puzzle

Today we’ll begin our long journey through the amazing world of DNA.
As we begin to look forward to a fun filled few weeks, its at this point that we look back into the past and discuss the important people who’s contributions and life’s work answered some of life’s biggest questions.

If you are using Puffin: Go to http://www.DNAi.org and click timeline, there you will a see a list of scientists broken up by decade. Use the web quest to determine which scientists to look up. You can read their biographies by clicking their picture. You can also have them tell you their story by clicking the animated icons above them.

If you are not using Puffin: Below are videos that are taken from the website DNAi.org. Use them to complete the introduction to these scientists as a part of this webquest (PDF).

  • Friedrich MeischerBio
  • Erwin Chargaff – Bio
  • Rosalind Franklin – Bio
  • Alfred Hershey & Martha Chase – Bio
  • James Watson & Francis Crick Bio

Together the contributions come together to fit like pieces of a puzzle (Read Here) and the shape of the DNA molecule was finally uncovered.
