1. The Median isn't the Message, discussed
2. Selection Lab , continued
Part C: survey the Fast Plants, posting the data to the shared set (3A data here, 4A data here). As a class, decide on and select a sub-group for the trait. Discard all plants not meeting the criteria. Water and return the selected lucky ones to the light bank.
Part B: Choose a 'beak', different from the beaks of the others in your group. Agree upon a procedure for the lab model. Identify variables, constants, objective, procedures, etc. Record in lab notebook as pre-lab.
HW: • Define the vocab (through Bottleneck Effect only)
• Correct sloppy SOAPS work on Median if you want the stamp. See the models on this handout if you are unsure.
1. Reviewed and Stamped:
15.1-15.2 notes; SD/SE Practice; Malthus excerpt
2. PPT - Variation...so what?
3. Variation Lab results discussed, written analysis
• Tell what you studied (organism*, variable)
• Describe, quantitatively & qualitatively, your sampled population
• Compare your population with another
• Address this Essential Q: Is this population varied? Does it have the potential to undergo natural selection? Justify with evidence.
* Common names: mesquite, palo verde, lodgepole pine, peanut. Look up scientific name! The
sea shell is the most challenging - try the link.
• Complete #3 above
• Bring in a grasping tool for a 'beak'
• Read from the Buffet: The Median Isn't the Message. Write a SOAPS* analysis.
15.1 & 15.2 notes stamped
1. From S to SEM
2. Compare your population with a second of the same species; same or different? Graph the two means with SE; compare the two in light of all descriptive stats.
HW: Make sure lab work is complete and up to date; Finish SD Buffet page (graph means + SE; analysis questions); Malthus essay analysis page
1. Got graphs and descriptive statistics?
What do they mean? PPT: StDev
2. Practice SD calculations: carrots v celery
HW: In the Buffet
• s'math page "Statistics in Biology". Complete the SD/SE calculations for each method the students used. Wait to do the questions.
• Finish 15.1-15,2 notes and questions (free-response q, NOT the MC)
• Read & annotate the Malthus essay "..On the Principles of Populations" Wait to do the analysis.
1. Text 1.1 notes/questions & Frog decline work stamped; finish frog discussion.
2. PPT - Evolutionary processes
3. Lab, continued
• organize data into columns in Sheets
• generate a histogram (bar graph)/data set
• generate/record the following descriptive statistics: population size, min, max, range, mean, median, mode, & standard deviation*
* use the formula =STDEV, highlight the column, hit return.
a) • Open your groups spreadsheet and save a copy for yourself.
• Finish the graphing and generating of data, as in 3, above.
• Paste the graphs into your lab notebook
•Record all the descriptive statistics above) for each of the graphs (no 'raw data')
•Title and date the page; subtitle as Pre-lab
b) Finish notes 15.1 & 15.2.
Review 15.3 (evidence of evolution) as needed
c) intimidated by Sheets? Go through this tutorial
1. Text 1.1/1.4 HW reviewed
2. Frog data: graph and claims shared
3. Begin Evolution via Selection Lab : Recognizing Variation
4. Evolution Buffet picked up
HW: • Finish WWD: Frog Decline (& 1.1 notes and questions as needed)
• Start the reading/notes/vocab on evolution syllabus (15.1 and 15.2)
DO NOT complete the Bufet work - its a units worth! I'll tell you what to do when.
1. Welcome! Grab Course Info, 'syllabus, Working With Data handouts
2. About the course
get texts! 12:55; 3:00
3. Dive right in: Planting Wisconsin Fast Plant seeds random groups of 4
4. Working with Data: Frog Declines
HW: • Continue with Working with Data through #3. Read about Hayes' work in the New Yorker
• Read/take notes/analyze the graphs in in the text as directed on syllabus
• Bring a lab notebook for next class
Come prepared to class with the usual materials: a sturdy lab notebook, writing implements (pen, pencil, highlighter, dry erase marker), calculator, etc.
If you are not familiar with Excel or Google Sheets, spend some time before class starts doing so. This tutorial is an adequate introduction.
See you Tuesday!
