This week, we discovered how the DNA code works. We discussed how 3 DNA bases code for an amino acid and that a group of amino acids make up a protein (the chemical messenger that tells the cell what to do). We even had the chance to "view" the DNA of a pea when we did our DNA extraction lab on Tuesday. When you get those labs back next week, just remember that you can take the "recipe" home and try to extract DNA from other sources! We began our discussion of selective breeding, cloning, genetic engineering on Wednesday. We watched a video that reviewed the advances and controversies of genetic engineering on Thursday and Friday. We will discuss some of your "ethical" opinions next week! We will take a 50 point "quest" over chapter 6 (DNA) on Tuesday, and then we will begin our next chapter on evolution.

A big CONGRATULATIONS goes out to the 7th grade PC students participated in the District Science Fair on January 24th. Esabelle, Kellyn, Jacob, and Evan all received first place standings. Kevin C., Nolan, Rob, Jason, and Patrick all received second place standings.

This week, students gave their genetic disorder presentations. Overall, I have to say that I was quite impressed with the projects! A large variety of Impress slide shows, brochures, and posters were produced by the students. Each class was able to learn about almost twenty different genetic disorders. Next week, we will discuss how DNA works and discover the basic principles of genetic engineering. We will even do a DNA extraction lab so that students can actually see what DNA looks like!

Saturday, January 24th, is the District 58 Science Fair. Our 7th grade PC students will be taking part in it this year. Come and cheer them on at O'Neill Middle School! The projects are open to the public from 10:30 to 11:30 in the morning.

We spent most of this week in the computer lab working on our genetic disorder projects. Students will be doing their class presentations next week. Students - be sure to follow the rubric closely so that you know what my expectations are! The projects (poster, slideshow, or brochure) will be due on the day of the student's oral presentation. Remember that I will need your white research packet and a copy of your poster text, brochure, or Impress slides on the day of your presentation! The projects are looking great so far, and I look forward to seeing them next week. Next week we will also build an edible DNA model in order to reinforce our learning about DNA's structure.

Our 7th grade Project Challenge students are working diligently to finish their science fair projects. The science fair is a mere week away! If want to check out their projects, you can attend the science fair at O'Neill Middle School on January 24th!

This week, we discussed the structure and history of DNA. We learned how DNA replicates and how DNA nucleotide bases pair up (like puzzle pieces). Students were also introduced to their next big project of the year. Each student (or group) will be required to research a genetic disorder and present their findings to the class. Students may choose to create a slide show presentation, poster, or brochure to inform their classmates about their topic. Students will have FOUR days next week to work in the computer lab, so don't expect to see much work coming home! Students have received a detailed project rubric in order to guide in their research. We began our research on Friday, and it looks like students are off to a good start!
