One more day I promise

Sorry guys. I know you’re excited to hear about baby Cooper and get back to our normal routine, but I’ll need one more day at home supporting our new family.

On the plus side, its a pretty easy day to celebrate winterfest. Here is the gameplan:

Biology

You’ll be watching the movie Gattaca today. Here is the trailer:

In the back of the room is an assignment I’d like you to fill out as you watch. Please keep it in a safe place because we’ll be watching the movie over about 3 class periods. Its a great movie and will start some pretty interesting convo (for example, keep an eye on the staircases).

If for some reason you cannot play the movie, you can work on your study guide for Common Assessment #3. Here is the link.

** Word on the street is you had trouble with the answer sheet for yesterday’s quest. We’ll discuss this on Monday so don’t worry about it too much.

SEHS

Keep working on those Nutrition plans. We start Unit 5, Biomechanics, on Monday.

Since I’m not there, I’ll throw one more pic your way. See you Monday!

Yes, those are Ohio State socks. The kids got good taste.

Thursday, February 19th agenda

This is you walking from Kelly Hall to Loretto

Hey, sorry I can’t be there. My wife and newborn son Cooper had a little longer stay in the hospital, everyone is healthy and happy, but I’ m going to take just a little more time to attend to them. That being said, I’m going to make some adjustments to the plans we had discussed before I left last week. Here is the gameplan:

Biology:

1. Instead of a Unit 8 Test, we’re going to do a “quest” (not as long, not as many points). I’m also going to allow you to use notes and ask each other questions. YOU ARE NOT PERMITTED TO WORK TOGETHER OR SHARE ANSWERS. But you can ask each other for clarifications, explanations, or double checking work.

2. Use the link below to be taken to the answer form for the quest (we’ll do this quest on the iPad so I can grade it from home. Keep in mind the class period is shorter and you cannot “save” progress. You will want to have a piece of paper and pencil to work on punnett squares.

Link → Unit 8 Genetics Quest

3. Next week week, we’ll be watching a movie AND preparing for your common assessment. If you would like an early copy of the study guide you can find it on the biology semester 2 page.

SEHS:

Good news… I’m going to give you an extra week to turn in your nutrition guide. However! We will still be working on Unit 5 and following the daily goals for that unit as scheduled. I just figured it wasn’t fair to give you a huge assignment then disappear the week it is due. So continue to work on it but if you have questions you don’t have to panic about me not being there.

All:

I’m sure this is what you were waiting for…

The Unit 7 Hunger Games

Today in #hbio we’ll be reviewing for tomorrow’s test over Unit 7. To review, you’ve been selected to be Tributes in the Unit 7 Hunger Games!!! Ok, so its not life or death survival of the fittest, instead we’ll be doing a speed stations activity. There are 32 stations posted throughout the room. You and a partner will try to complete these stations as ACCURATELY & QUICKLY as possible. You are Competing against the other players in your class. The fastest, and the most accurate, will receive a bonus point.

At the end of the day, I will post the stations on this site for you to review with. Be sure to study your Unit 7 Study Guide as well. Good Luck, and may the odds be forever in your favor…

MEiosis and MItosis… what’s the difference?

Mitosis vs. Meiosis

“So what’s different about Mitosis versus Meiosis?”

 

Well looking at the picture we see Mitosis on the left… There is a single cell, which duplicates its chromosomes, divides, and the result are two cells identical to the parent cell.

Meiosis, on the right, all those same steps occur… BUT THEN! Another cell division occurs! We do PMAT a second Time (Thats Cray-Cray Mr. K)! The result then are 4 cells, with half the number of chromosomes, and each one has a unique set of chromosomes.

I know what you’re thinking… “But why would we only need half the number of chromosomes? Doesn’t each one of the cells of our body need all 46 chromosomes!?”

It is true that each one of our Somatic, or Body, cells needs a complete set of chromosomes. But our Gametes, or Sex Cells, only need half the number of chromosomes. This is known as being Haploid, or having one set of chromosomes. And I bet you already know why! That’s right, the other half comes from the 2nd parent during sexual reproduction (That’s off the chain Mr. K). When the male and female gametes meet (Fertilization), they combine to form one new cell called a Zygote that has two sets of chromosomes, one from Mom and one from Dad. This is known as being Diploid.

Crossing Over

The Red X and the Blue X are duplicated chromosomes. During Prophase 1, they sometimes “Switch Legs”. This is known as Crossing Over.

The coolest part about the whole process is that it makes you Unique. And not in the Sesame Street, “You are special,” kind of way. More like, there are more than 8 million different genetic combinations that you can create in each of your gametes and they are assorted completely randomly (Independent Assortment), meaning that for each of your 23 pairs, you can give either one of the chromosomes, its not predetermined! And sometimes, Duplicated Chromosomes will even switch pieces (Crossing Over) making them even more unique!

All in all, Meiosis is a pretty unique process and I hope you enjoy learing about it as much as I enjoy teaching it! To learn more about Meiosis and how it causes genetic variation, check out my YouTube video below!

The DNA (web quest) Puzzle

Please watch this YouTube video for instructions on today’s lesson:

Today we’ll begin our long journey through the wide 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 links to videos that are taken from the website DNAi.org (provided you are using a computer with flash or the Puffin App). Use them to complete the introduction to these scientists as a part of this webquest (PDF).

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

Unit 3 Post-Test: So what do you know NOW?

Click the link below to prove how much you have learned about Cells…

Unit 3: What do you think you already know

Reminders: Your Biology – Unit 3 Test is tomorrow! It will cover the following topics:

  • Cell Theory
  • Scientists who contributed
  • Types of cells (compare/contrast)
  • Cell Parts
  • Protein creation

Hopefully later today I’ll begin to post the projects you’ve created to YouTube and to this site. Feel free to come back and see what a great job you did.
