Students may write a two page, typed, double spaced report on a genetic disease.

Must include the following information:

a. Name of disease

b. How it is inherited

c. Symptoms

d. Prognosis

e. Who is affected (is the disease known to target certain races, genders, or ethnic groups, etc.)

d. Sources (separate page)

e. Title page (separate page)

f. Pictures are always great if they can be obtained but are not considered part of the two typed pages.  There should be an extra page designated for pictures if included.

 *Please be aware that plagiarism will not be tolerated
(no cut and paste, or copying word for word).  All sources must be cited. 

 Extra Credit Option #2:  Worth two test grades (200 points)     Due:  Monday, March 7^th

Students may construct a model of DNA.  No purchased kits may be used.

·         Sugars, phosphates, and bases should be represented consistently.
      (Meaning all sugars look alike, all phosphates look alike, all adenine bases look alike, etc.)

·         Base pairing should be accurate (A-T, G-C). 

·         Must include a key that shows what represents each part of the DNA model. 
(The key should show what is representing the sugar, the phosphate, and each base pair.)

·         The model must be a double helix.

*Information can be obtained from the textbook (chapter 6), reliable online sources, or you can contact me if you have any questions.

Impact of School Closure Thursday

 

Impact of school closure Thursday, 2/10

In class yesterday, we discussed the impact a delay/closing would have on the plants test scheduled for Friday.  Please see the following notes for details regarding what the students were informed of yesterday in class:

• The test will go on as scheduled, regardless of delay or closing.  (Due to the snow days and delays, all 7th grade science classes are adhering to a tight schedule in order to complete the required material before the Alabama Science Assessment.)
  
  
• Scroll down to view other resources will be available for review.
  
  
• I have posted the study guide and key. Please remember, it is just a review of the material that has already been covered and will not be required.
  
  

***If your student has remaining questions on this unit, I will be available before school Friday beginning at 7:00 am.  Students will be given 10-15 minutes to study or ask questions prior to beginning the test. 

We have thoroughly covered this material, with many review & reinforcement activities.  Students who participate in class and complete their work should have no problems with this test!
