Making Learning Irresitable for Over 25 Years. Making Learning Irresitable for Over 25 Years.
End of the Year

Here are a few pictures of our end of the year projects. The first set are of students picking through owl pellets...owl puke, not owl poop! Owls do not digest hair and bone so they compress these materials and spit them out at a later time. The skeletal remains allow us to study owl and rodent populations, such as which animals are prey in a given ecosystem, if a particular prey is in danger of becoming extinct, and the carrying capacity of a given habitat.

Bacterial Transformation Successful

Last week, students inserted a jellyfish plasmid into bacteria. The jellyfish gene codes for Green Fluorescent Protein (GFP) and is resistant to the antibiotic ampicillin. Students who successfully performed this transformation were able to produce bacteria that fluoresced green under UV light and are resistant to antibiotics. A podcast will follow soon!

Jellyfish and E. coli

To conclude our unit on genetics, students will be engaging in an amazing transgenics lab. Students will take a DNA plasmid extracted from a jellyfish and insert it into the DNA of bacteria, designing a new species of bacteria which manufactures a protein that fluoresces under UV light and would otherwise not exist in the wild. Our students are getting an authentic look at how genetic scientists are using new technologies to create treatments (and hopefully someday even cures) for diseases such as diabetes, hemophilia, and sickle cell anemia to name a few.

The jellyfish we will be stealing DNA from is the Aequorea victoria. This awesome bioluminescent jellyfish actually glows in the dark thanks to its genes for GFP, or Green Florescent Protein. To check out what we'll be doing this week, click on the pGlo Transformation Student Manual.

Cloning by Cutting

Cloning is the genetically identical duplication of an organism through asexual reproduction. Scientists have made some mind boggling achievements with cloning, including the asexual reproduction of sheep and cows. There is much ethical debate as to how far and for what purpose cloning should be used. However cloning, or asexual propagation, has been common practice in the horticultural world for hundreds of years. Simply taking a stem cutting from a ‘parent or mother’ plant, rooting and planting it to create a new plant is cloning or asexual propagation in it’s most basic form.

Selective Breeding

Today students learned about selective breeding. Selective breeding is when two organisms with desired traits are selected to serve as the parents to the next generation. We are studying two types of selective breeding, inbreeding and hybridization. Inbreeding involves crossing two individuals who have identical or similar sets of alleles, which will result in the offspring's traits being very similar to their parents. An easy example or model for students to understand is dog breeding. For example, two pug parents make pug puppies. Hybridization occurs when breeders cross two genetically different individuals, which results in the offspring inheriting the best traits of both parents. Examples of hybrid dogs include puggles, cockapoos, labradoodles, goldendoodles, pomapoos, and so forth.

Inbreeding -

Pug+Pug-1 = Exqisit1-1

Hybridization -

Pug-2+Beagle-Dog = Dippy.Jpg

Diagnosing Genetic Disorders

Years ago, doctors only had pedigrees and Punnett squares to help predict the inheritance pattern of genetic disorders. Today, thanks to modern technology, doctors use tools such as amniocentesis and karyotypes to help detect genetic disorders. During amniocentesis, doctors use a long needle to remove a small amount of fluid that is surrounding the developing fetus, or baby. The fluid contains cells from the baby that can be examined and used to create a karyotype. A karyotype is a picture or arrangement of the baby's chromosomes and can reveal whether the baby is developing the correct number of chromosomes.

Genetic Disorder Library

A genetic disorder is a disease that is caused by an abnormality in an individual's DNA. Abnormalities can range from a small mutation in a single gene to the addition or subtraction of an entire chromosome or set of chromosomes. To learn more about different genetic disorders, browse through the Genetic Disorder Library by clicking on THIS LINK.

How do we get mutations in our genes?

We can get mutations in several ways:
1. Mutations can be inherited, or passed from parent to child. This type of mutation is called a germline mutation.

2. Mutations that arise sporadically throughout our lifetime (in non-sex cells) are called somatic mutations. Most of the time, our cells are very good at fixing somatic mutations when they occur. In the rare instances when they are not repaired, a medical condition may result.

3. A third type of mutation, called a novel germline mutation, is a combination of a somatic and an inherited mutation. The novel germline mutation arises in a parent's germ cell - either the father's sperm cell or the mother's egg cell. The child conceived through the union of sperm and egg carries the novel germline mutation.

Genetic Disorders

During the next few days, students will be studying genetic disorders. We will explore the causes and symptoms of various genetic disorders, study the inheritance pattern of genetic disorders, explain how genetic disorders are diagnosed, and describe the role of genetic counseling through biomedical technology. Here's a sneak peek at a few images and articles we will be referring to during class.

Crime Scene Investigation

Students are studying the different uses of DNA fingerprinting by participating in a mock Crime Scene Investigation. Students received police reports, collected DNA samples from the four suspects, and evaluated the DNA found at the crime scene. Students evaluated the base pairs, Adenine, Thymine, Guanine, and Cytosine, and charted their molecular weight to form a unique pattern of bands. These bands are used by police and investigators to assess the DNA evidence of victims, suspects, and perpetrators.

This week, students are learning about DNA and its effects in the courtroom. Technological advances in DNA have revolutionized how crimes, paternity, diseases and other medical cases are studied. Tomorrow, students will try to find the guilty party in a mock crime scene by collecting and analyzing evidence. Attached is an article that may be of interest to some of you Forensic Science fans. The article, DNA On The Witness Stand, highlights the investigation into the real-life mass murder of 15,000 Argentineans during a period of political unrest in the 1970s.

Blonde Chias?

When we began our Chia experiment, students designed an independent variable that would test the effect of light on the growth of a plant. Group C was locked in a dark cabinet for almost two weeks, with no exposure to sunlight. Most students predicted the Chias would not grow any hair at all, but when the cabinets were opened yesterday, students were in for a surprise! The Chias did grow hair, but because they were not exposed to sunlight, the chloroplasts were not able to effectively produce the green pigment chlorophyll. The result was yellow and white grass!

Rotten Eggs

At last, the eggs have been laid to rest! Remember, last night students soaked their eggs in a solution of their choice. We had some really cool results! Here are some pictures of an egg that was soaked with a peppermint tea bag (and now smells like peppermint) and another egg that was soaked in laundry detergent and formed a light blue, shell-like coating.

Dsc01357Dsc01354

In the next pictures, you can see what happens when water diffuses out of the egg and into the cup. Notice the cup of blue detergent now has a layer of water sitting on top, water that was once inside the egg. Check out how deflated one egg looks next to another. Can you guess which egg was sitting in a fluid with a higher water concentration?

Last Night of the Eggcellent Eggsperiment!

So was the dye inside the egg or only on the membrane? Did you guess correctly? Check out the broken egg on the floor. When the egg went splat, notice that its insides were red. This is because the red water in the cup diffused inside the egg through the cell membrane. Now check out the eggs in the cup. Last night we soaked the eggs in clear salt water, so why is the water colored again? This is because the colored water inside the egg diffused out through the membrane and into the cup of salt water. The process of water moving from an area of higher concentration to an area of lower concentration is known as osmosis.

Why Pigs?

As you may already know, the pig organ system is most similar to that of the human. But did you know major research is going on to see if pig organs can help ease the demand for humans in need of life saving organ transplants? Check out some of the articles below.

Piggy Week is Next Week!

Students will be exploring the human body by participating in a pig dissection next week. As you may already know, the organ systems of pigs are most similar to that of humans and are becoming a major resource for organ transplants. The dissection will take place Monday-Thursday, with a lab test scheduled for Friday. Each day, students will follow an instruction and question packet to guide them through the dissections. Each night, students should review the packet, as its content will make up the majority of the test.

Hey Mom, look what I did!

As many of you may know, our students participated in a genetic transformation lab. Students took a DNA plasmid extracted from a jellyfish and inserted it into the DNA of a bacteria. For a week, they grew this new microorganism in the lab. They have completed a cutting-edge transgenic lab, designing a new species of bacteria which manufactures a protein that fluoresces under UV light, indicating that the new DNA has been successfully inserted into the DNA of the bacteria. Our students are getting an authentic look at how genetic scientists are using new technologies to create treatments (and hopefully someday even cures) for diseases such as diabetes, hemophilia, and cystic fibrosis to name a few.

3rd Period Parents

Dear 3rd Period Parents -

Please be patient with me as I try to finalize your child's grade. It has been very difficult merging three different teachers' grade books into one! I am in the process of entering each teacher's assignments, and then exempting your students who did not have that teacher originally...what a nightmare! Do not be alarmed if your child has a lot of exemptions (E), missing work (M), or if their class average is a 37. Everything should be back on track by Monday. Thank you for your patience!

No Homework Left Behind Misinformation

Dear Parents -

There has been much confusion for both teachers and parents concerning the No Homework Left Behind Policy (NHLB). I recently spoke with Dr. Tyson in an attempt to clarify the misinformation.

What is the No Homework Left Behind Policy(NHLB)?
All students are encouraged to do all of their homework, at all times. Students will be retained from Connections after arriving to school without homework. After the third offense for an individual teacher, (three for Ms. Larkin, for example), the child will serve a day in ISS Study Hall.

Is my child really in ISS and will it hurt their discipline record?
NO! Your child is not technically serving ISS, only going to a location that is quiet and will allow them to get caught up on their work, while also undergoing a study skills and work habits course with the ISS teacher. The "ISS" will not at all damage your child's conduct or disciple record in any way since they are not truly serving an ISS...think of it as a study hall with guidance.

Can my child still go to Jekyll Island if they serve a NHLB ISS Study Hall?
School policy will not allow any students who have had ISS or OSS to go to Jekyll Island. However, the only exception is for those students who have served an ISS Study Hall in relation to NHLB. Because the ISS Study Hall is not considered a true ISS and is not at all related to discipline issues, those students will be allowed to go to Jekyll Island assuming there are no other major infractions on their disciple record that have resulted in an ISS or OSS.

What are Block Parties and who can go?
Every 9-week grading period students are eligible to attend a 30-minute break or party as a reward for good behavior and hard work in the classroom. Students who may attend have not had ISS, OSS, and have not served an ISS Study Hall during the current 9 weeks. This is not a punishment, it is a reward to students who study hard and behave as young men and women are expected to behave!

Course Description

This year, students will engage in research and inquiry activities that include experimentation, data analysis, and real world issues relevant to science and technology.

Seventh grade science will focus on the study of the characteristics of living things and the cycles and interactions between living things and their environments.

Academic class periods have been extended to include time to also develop reading skills in the content areas.
The seventh grade science curriculum, as defined by the Cobb County School District (CCSD), includes the following Power Standards:

The learner will be able to
• utilize science process skills to engage in scientific inquiry.
• recognize and utilize the SI System of measurement.
• recognize the cell as the basic unit of life and describe the structure and function of its major components.
• demonstrate an understanding of the structure and function of the systems of the human body.
• explain and illustrate how genes work together to create the traits of a living thing.
• explain the methods biologists use to name and classify living things for the purpose of communication and study.
• explain interactions between organisms and their physical environments.
• explain that change over time is evident in the past and current diversity of organisms found on earth.

Visit the CCSD website (http://www.cobbk12.org) to view the complete list of curriculum standards. Select the PICASSO link on the right margin of the page. Stay on the Parents tab and select science from the list, finally choose 7th grade.

posted on: August 09, 2005

Expectations

The seventh grade policies and procedures apply to all science classes.

Safety is a primary concern in the science lab and students need to be well behaved. Students will sign a safety contract as a part of our safety unit during the first few weeks of school. Students who do not follow directions and obey safety guidelines during lab activities may not be allowed to continue the activity for the day. A lowered grade should also be anticipated for the activity. During outdoor learning experiences, students are also required to obey all classroom safety rules and guidelines.

Students are expected to reserve a section of their binder for their science notebook that includes science notes, lab reports, and other activities. Your teacher will give directions for organizing your work. It is the student’s responsibility to maintain a neat science notebook. Quality work is desired and expected. Periodically during the year items from the notebook may be selected to save in a portfolio.

posted on: August 09, 2005

Grading

Grades will be determined using the following guidelines:
o Tests, Major Projects 40%
o Classwork, Activities, Labs, Quizzes 50%
o Homework assignments 10%

Time at home will be required to preview material, complete projects, finalize lab reports, read the textbook, learn vocabulary and content, and review for tests. These items will not be included in the 10% portion of the grade even though many of these things should be done at home (outside of class time).

posted on: August 09, 2005

Student Absences

Students are responsible to make up any missed class assignments or tests when absent. Make arrangements with your teacher when you return to class for a time to make up tests or lab activities. It is the student’s responsibility to communicate with your teacher if you have any concerns about assignments.

posted on: August 09, 2005

Introducing Intelligent Behaviors

Plan for success in science class by modeling intelligent behaviors:

• Decrease impulsivity
• Listen to others
• Practice persistence
• Think flexibly
• Think about thinking
• Strive for accuracy and precision
• Question and pose problems
• Apply knowledge to new situations
• Think and communicate with clarity and precision
• Gather data using all your senses
• Demonstrate ingenuity, originality, insightfulness: creativity
• Respond with wonderment and awe
