Title
Problem Statement
Hypothesis
Data table
Diagram (sketch Nov 11 and Nov 30)
Conclusion
-two things you learned and one question you have.
Abiotic factors experiment due Monday.
20pts.
Turn in your own work, not a group product.
Problem- You should have two testable questions.
Hypothesis- You should have a hypothesis for each question.
Graph- This should be a line graph with four lines on it. Each line represents one plant. You should plot growth vs. time. Use a different color for each line.
Conclusion- Answer your two questions with data. Accept or reject each hypothesis.
Include the rectangle of the walls of the classroom to scale as well as the three lab benches also drawn to scale.
Create a legend to include student desks, teacher desk, doors, eye wash station, cell phone pouches, and safety goggle storage area. These do not have to be scaled, just approximated.
Write a response to the New York Times article on antibiotic resistant bacteria. Use the following format:
Cause and Effect
Paragraph 1- Discuss the chain of events leading to antibiotic resistant bacteria. What is the cause of this issue?
Paragraph 2- What are the current and future effects of this problem? What is your opinion on the best course of action or solution to this problem?
In your essay be sure to include specific strains of bacteria and specific antibiotic drugs. Explain how antibiotic drugs work and how the bacteria evolve resistance to the drugs.
Design an experiment to investigate factors that affect mold growth on bread.
The goal is to grow the most mold possible in the class.
Follow the lab report format on my webpage as a guide for this experiment.
Your background info should include information about the type of fungi that bread mold is, the phylogeny of this fungi, and how preservatives inhibit mold growth.
Make sure your have a treatment and a control group.
Go to this link. Cladograms
Watch the intro video.
Make your data table.
Create the Venn diagram.
Build the cladogram.
Show Lynn when you are finished.
If you have time, explore the site and read about cladistics(birds and reptiles).
Learning Goal: Construct a decay curve for a hypothetical radioactive isotope which has a half life of 2 minutes. Practice with the concepts involved in radiometric dating.
Cut out 100 .5x .5 inch squares out of printer paper. (you can use random.org coin flipper to model this if you don't want to use paper)
On one side write H and the other write T on each piece.
Drop the 100 pieces from eye level and allow them to fall to the floor.
Count the number of heads and tails.
H represents parent isotope atoms and T represents daughter atoms.
Repeat the above procedure but only drop the parent isotopes. Remove the daughter atoms.
Construct a decay curve for this isotope. On the Y axis plot number of parent atoms remaining. On the x axis plot the number of half lives.
Each time you do a drop represents a half life.
Complete each drop every two minutes.
Repeat the procedure until you have no more parent isotopes remaining.
How long did it take for all of your parent isotopes to decay?
How many half lives took place?
How old would a fossil be after the 4th half life according to your graph?
What questions do you still have about radiometric dating?
What was the ratio of parent to daughter atoms for each half life?
Use your graph to find the age of the sample when 30 parent atoms remain.
Skin moisture is controlled by the following alleles. D = normal d=dry
Teeth are controlled by: T= straight teeth t= crooked
Cross a heterozygous father for both traits with a homozygous normal skin and crooked toothed woman.
Write the genotypes for each parent.
Make a punnet square and show the possible outcomes.
What are the phenotypic ratios?
10 pts
Write a two paragraph essay over a genetic disorder of your choice. In paragraph one, describe the genetic problems which lead to the disorder taking place. In paragraph two describe the disease itself. Each paragraph needs to be at least 5 sentence. Provide an MLA source citation at the bottom of your paper. Be prepared to read to the class on Monday. 25pts
The plate boundary maps will be completed in class today and students should turn in the map page into the inbox today. We will go through the analysis questions as a class.
Have Lynn check your surface area to volume ratio data table from Tuesday.
Reading questions chapter 10 due Friday.
Turn in the agar cube diffusion lab from Wednesday today!
Attendance- you will have difficulty passing if you have more than 10 absences for the semester.
Test Corrections-a lot of the grade is based on tests 60%, if you do not do well make sure you complete test corrections within one week and be sure to follow the posted guidelines.
Organization- you should keep a notebook and binder just for science and keep them in the classroom.
Effort- science can be a difficult subject for some, effort goes a long way towards learning. If you try your best, then you will succeed!
Today we will wrap up the Earth models and do a remote sensing activity in class. Make sure you have Lynn inspect your model along with the data table for a grade.
Study the image in your text on the light reactions. What is the goal of these reactions? What are the raw materials and byproducts? Know what happens at each photosystem and why.
