Mutations

We have been talking about DNA mutations for the past week in class.  Today the explanations of the different types of mutations and how they can influence the protein and traits of individuals were discussed using notes in our notebook and these pictures:  Mutations and this powerpoint for the notes:  Mutations Notes

Alien Encounters!!

Last Fridays howework was collected as well as Warm Up Notebooks

After the probe landed on the comet last week, scientist has isolated organic molecules.
Our class determined it was DNA.   We determined the sequence of DNA and have deciphered the codons from RNA to determine traits and how this alien should look.

Students were given a mock DNA strand and followed the procedure for the activity posted here:  Alien Encounters!

HOMEWORK!!  Students should have the data sheet and alien drawing BEFORE coming to class tomorrow.

The answer sheet and drawing of their alien was glued into their lab notebook after the Title and purpose.  Student tomorrow will complete questions A-F in the lab notebooks as well.

Warm Ups Week of November 17th

Here is a link to the warm ups from this week:
Warm Up QOTD week Nov 17th

DNA Models Turned In!!

I am so very excited to see the DNA models due today.  Students had three weeks to complete this assignment.  Here are some of the examples turned it so far.

Also today we took a quiz on Transcription and translation and worked on completing the DNA base pairing sheet from last week (certain sections have been for homework for the past week).
This sheet is due MONDAY if not completed in class.

DNA Candy Lab Continued

Today we continued our DNA candy lab by demonstrating translation.  We deciphered the codons for their amino acids, then used tape as peptide bonds to create a protein.

On our activity sheets from yesterday we were able to complete up to number 18.

Reminder DNA model DUE friday!!

DNA Candy Lab

Today and tomorrow to demonstrate another example of a DNA model for the project due Friday we made DNA out of candy.  We also demonstrated Transcription and Translation using candy as well.  The link for the handout is here:   DNA Candy Lab

Qotd warm up week nov 10

Here is the link to the warm ups for the week of November 10th qotd week of Nov 10th

Vocab and Questions part 2

Today we continued our work on enhancing this unit with vocabulary and questions:

Chapter 12 section 3  Vocab p 300
                                    Section Assessment p 306 #1-5

Vocab and Questions

Today we practiced DNA to RNA using questions out of the Biology textbook

Chapter 12 section 2  Vocabulary p 295
                                    Analyzing Data p 296 #1-3
                                    Section Assessment p 299 #1-5

DNA vs RNA

HOMEWORK:  DNA Base Pair Sheet # 13-16
Today we took some notes on DNA vs RNA as seen here:

We completed #6-12 on our DNA Base Pair Sheet from last week.
We then used pop beads to demonstrate Transcription and translation using a student created 12 base pair sequence.  The colored beads directions are as follows: Pop Bead Activity


Pictures of what the students created:

Friday DNA wrap up

Today we took a quiz on DNA and the homework from yesterday was checked

We also completed the lab questions from yesterday.  A link to what the students should have completed is here: DNA Checklist

A link to the lab questions can be found here:  DNA Extraction Lab and Questions
The answers are in the reading as well as in their notes.  We did many of the questions together as a class.   Question 12 and 13 we did with a visual as seen here:

Lab notebooks were collected as students left the classroom.
Reminder DNA model due November 21st!!!

QOTD week Nov 3rd

Here are the Warms up from this week.  Warm up notebooks will be graded the week of Nov24th.

QOTD week Nov 3rd

DNA extraction lab

Students completed the notes from  yesterday.

Students set up today's lab in their notebooks with Title (TOC), Purpose, and answer questions 1 and 2 in their notebook.  They will complete the rest of the questions tomorrow.  Science notebooks will be collected tomorrow for grading of the Epidemiology, Classification, DNA, and DNA extraction content completed the last two weeks.
Students then used Gatorade, dawn dish washing liquid and rubbing alcohol to extract DNA from their own cheek cells.  A power point we used in class can be found here: DNA Extraction

We also were given a homework packet that students will be using for the next two week.  Tonight homework is #1-6 due Friday Nov 7th.  We started this in class so all students should have at least number 1 completed.

DNA UNIT Homework

DNA Timeline

Today we created a fold able for the major discoveries around DNA's structure.  This is along side a video going into more depth of each discovery after 1944.
 We used the following page for the pictures, names and dates: DNA Timeline Fold able

We will be completing this assignment on Friday after our Quiz as tomorrow we are extracting DNA from our own cells.

Here is a  link to the video: DNA secret of life

DNA - Episode 1 of 5: The Secret of Life - PBS Documentary

Voting day

Today we did not have school but I spend my day asking voters to vote yes on issue one!!!  Can't wait till you are all d enough to vote and help out country make decisions that last a lifetime 

DNA

Today we used the colored DNA we made last week and took note on the basic building blocks of DNA.
The DNA model project was handed out today.  it is due NOVEMBER 21st!!  it is 100 points so please do your best and DONT SLACK!

Fernald preserve field trip

Yesterday we went in a field trip to fernald preserve in Ross ohio.  The student did great considering it started sprinkling on our hike and had to be cut short.    They seemed to love to feel the animal pelts and watch the field cameras    Here are some examples of fun. All day
