DNA Replication Models

Today in Bio, we’ll be starting our work on our Replication Models. They are great visuals of how the process of replication actually looks. In order to complete the model you will need the following:

dnahelicaseThis is a large undertaking and will take us a few days to complete. To keep track of our progress there are checkpoints listed in the directions as well as a photo journal to keep. The photo journal should include several pictures of you and your group working as well as a description of what is taking place on your model.

When you are finished, you will hang your model somewhere in the school building for all to see. Then snap a picture of it hung up and email it to me, along with your completed photo journal, at jkubuske@gocathedral.com

If you need a refresher of how DNA replication works, here are the notes from the other day. Have fun and good luck!

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.

Friday Sep. 19th

I won’t be in this morning, but I will be back for 5th & 6th period if you need any help. Here is the plan for SEHS & XBio this morning.

Biology

    1. Pick up your worksheet from the table. Do the “Prokaryote Reading” first. Read the passage and highlight any information you think is important.
    2. After racing, answer the questions, label the picture, and color the picture on the backside.
    3. If there is time leftover, you can start your cell part chart which we’ll be going through next week. Below is the YouTube video that will help with your chart.

SEHS

Your IAs are due Monday! Use the example papers to write your papers. Here are a few tips and reminders:

  • Data – Your data collection section will have two parts: Raw Data & Processed Data. The processed Data includes a table with mean, standard deviation, 2 standard deviations, upper range, lower range, and Ttest. It also would include all of your graphs.
  • Conclusion – Is a description of what your processed data says
  • Evaluation – Is a description of what may have influenced your data or not done quite right. For each limitation, write a way to improve it in the future.
  • Bibliography – MLA format
  • Visual Aide – Search “infographic” on google and use an example as a guide. Think of it as a colorful illustration of your data.

I’ll be back to help this afternoon and will be available after school to help. Have a great day & BEAT ST. X!

Evolution Projects

Check out some of the amazing work our Honors Biology students created to share with some local middle school students to help them learn the basics of Evolution:

 

Some of the students created twitter accounts for middle schoolers to follow and included key concepts as well as #hashtagvocab

 

 

The Scientific Method

Biology students, today will be our first time taking “Notes”, although today’s notes will be more of a review of a concept than the introduction of a concept. On the Bio- Semester 1 page, you’ll find a link to the video below as well as to the handout that corresponds to it. I would encourage you to decide today how you plan to take notes in class (notability or paper), and then decide how best to redo the notes neatly and orderly on notability or on the paper version (yes this means you will be writing the notes twice).
