.  ___________________________________________________________________________________________________________________________

9/13 – Monday – A Day – Academic Study will be tomorrow

Main focus 
     a) To observe % germination and phenotype on Day 3 of fast plants
     
     b) Calculate with central tendencies using the germination percentages of the class.

Period 8  – AP Biology Class – 
 
1.  Day 3 – FAST PLANT Data Collection and observations- 
      Students will draw a grid in their lab notebooks to identify phenotype and germination.  
      Height of plants will also be measured.
What is happening right now with our FAST PLANTs

We will calculate the mean, sd and SEM of our germination data as an activity tomorrow.

9/13 – Monday Homework: –

1: Answer questions to the Ant Research Article –  I am giving you a research article to read and interpret. I will help you understand this in the Academic Study Hall tomorrow. Please try your best to answer the first 6 questions. You can make edits to these answers up until Friday when it is due.  The skill of interpreting biology research is the skill that I want to develop for you and one that you need for this course.  Think what the dependent and independent variable are!

Whole article due Friday  9/17 at 4:30 am  – The Ant Odometer Article: (quiz x3)
Tonight – Questions 1 – 6 are due Tomorrow but the whole set of questions are due Friday

    a) I will share a google doc with questions that I want you to answer with your personal email that we used this summer. 
 
Make sure that you are logged into google with your personal email NOT the school gmail!
 
I will give you a hard copy of this tomorrow.

9/14 – Tuesday – B Day – Academic Study Hall Today

Main focus 
     a) Research Ant Article analysis.
          (Be able to identify the IV DV and hypothesis of an authentic article.)  
     
     b) Continue with Fast Plant data collection for germination, growth rate, and     
          phenotypes.

 

1. Review the basics of the Ant Article – 
    with NPR Video of the ANT research media.
h
2: Observations on Fast Plants/Marble notebooks –     
      Measuring germination only today…New observations
     Notes on seed coat and Life cycle.
 
3. Excel activity with Height data begins
 

 NPR Video of that will help in the investigation of Ants:  .

Notes for the Lab will come from the following presentation:

9/14 – Tuesday Homework: –

1. If you have not already completed last nights form using 3 submissions please do so tonight.
 
2. Please continue with the article’s questions – Due This Friday!
 
3. Review Whisker box statistics/if needed – 
– The Ant Odometer Article:
j
The following is a short video on whisker box statistics that they use for their error bars. You will need this to understand the data.  The error bars they use on the boxes are not Standard error.  I did go over theses box plots in both classes but if you need to review the video is waiting.
 
Remember the box plots are just middle 50’s which just mean 50 percent of the middle of the Normal Distribution of values with the Median in the middle.  They call these box plots IQR’s  (Inter Quartile Range’s) .  The whiskers are the outliers AND WE DO NOT use the outliers (or whiskers)  to see if they overlap!!!  I am an outlier (+2 or more SD from the mean in height) and you would not judge or make any statistical  judgements on my height FOR the entire population. Example:  How does the airline industry determine the size of seats and the distance between them? Would they use the my height to make these determinations?  We care about the population around the norm (mean or median) and we care about the majority of the ants are doing and not the outliers.  So we look to see if the boxes overlap or not for a determination of significance.

 Box Plots and Wiskers Statistics explained for the ANT research Article.  .

End of Tuesday!

9/15 – Wednesday – A Day – 

Main focus 

     a) Continue with Fast Plant data collection for germination, growth rate, and                                 phenotypes.

     
     b) Use Excel to setup spreadsheets to calculate mean, sd, SEM And graph first three 
           days of height data.                                                                                                                                    

We are measuring the heights of our Fast plants grown in fluorescence lights and those growing in under the LED lights to see if there is a statistical difference using the Standard Error of the mean.

1: Observations on Fast Plants/Marble notebooks –  
   – DAY 5   – we will split some groups into the LED testgroup
      Measuring germination only today…New observations
