labs

For lab report samples from your classmates scroll down and find it under Writing AP BioLab reports.There are 12 college board required labs - most schools try to cover these (that means everything you want to know about the labs is available online and plagiarism is easier to spot than you think). We will do the same and attempt to do a few more beyond the required labs! The reason why your AP Bio course is more intense than say APUSH is because we have to cover labs and all the material in that really voluminous text in 8 months (oh! btw college board has finally caught up to this burden on AP BIO students and has decided to reduce the load by streamlining the curriculum next year!). Labs are the fun part of AP Bio and since you will write some lab reports in groups, it can be relatively pain free. Remember you have to use turnitin to submit lab reports to check for originality!

Scientific method ,'variables vs controls', hypothesis: 1) Class powerpoint
2) Scientific Method - Review of Variables and Controls - practice h/o
3) Writing if-then-when hypothesis statements practice h/o

Prelab:
Word document on how to write a prelab - needs to be completed BEFORE every lab in your 60 page lab notebook

Writing Ap Bio Lab Reports:
1) lab report format, check list, and self-assessment (word document) - Download and print a self-assessment for every lab report unless instructed otherwise.
2) lab report samples from the web- by no means are these complete or aligned with my expectations. Use as a quick reference check only! Remember no plagiarism!
3) Lab report samples from your classmates- click on yellow highlighted words: Pill bug lab report sample, DO lab report sample - use these to see how the Introduction and Discussion sections need to be organized for flow of concepts and application of web based research.

Using Microsoft Excel - Tutorial A (19 minutes long; data tables construction, simple functions such as average and standard errors; statistical test for significance using Student's t test), Tutorial B (graphing - 20 min long - if you are having trouble viewing these tutorials - download VLC player from the internet (click here) for free and it will work if you right click and specify 'open with' vlc player! You have to right click (Mac - ctrl + click) on 'Save as' - and download tutorial video to your computer first! Quicktime does not work - you will hear me but not see anything - USE VLC!

Web Resources:
1) ap labs - Prentice Hall Biology Place - Best lab link
2) Writing in Science - from George Mason Univ. Click on individual sections so see samples and also go to Practical tips on Writing. One item that is missing there - use active voice when writing (not passive).

ap labs word document downloads

Unit 1: Biochemistry - click on yellow words to download word documents accompanying the labs
1) Macromolecule Lab -
you will be given 4 unknown powders. You will bring positive and negative controls of Benedict's test, Iodine Test, Biuret's test, and Lipid test from home. Compare the unknowns with the positive and negative controls and rate the unknowns as instructed. Use this h/o and complete the discussion section and data tables.
2) Enzyme lab AP LAB #2 - has several parts. First part is a simulation for you to be a remarkable, outstanding ENZYME yourself (every high school student's secret ambition)! You will become 'toothpickase' and simulate the effect of temperature, pH, or inhibitors/activators in this activity on the rate of enzyme catalyzed reaction by getting creative! The third part is designing and doing an actual experiment using Lactaid pills and milk and testing the effect of pH and temperature on the enzyme activity. Click - Excel Document - Class Data for toothpickase lab! This excel document tells you what graphs you need to have in lab report for Part A! Second part may be skipped. Lactase lab report guidelines - click here! Lactase lab class data click here!

Unit 2

1) Diffusion/Osmosis - AP Lab #1 - Too many parts... First there is the milk magic and understanding how hydrophobic and hydrophilic interactions work in this spectacular color kaleidoscope display (a paragraph comparing the 3 milks and a Scientific explanation of the events leading to the "Aurora Borealis" like colors in milk to be submitted;
Formal lab: Part 1- Demo using glucose/starch/IKI to determine how both solute concentration and pore size matters when it comes to diffusion/osmosis; Part 2- Next you will investigate how osmosis works in dialysis bags as a model of the semipermeable membrane using Sucrose solutions; Part 3 - pick a veggie (sweet potatoes, the regular spud, or zucchini) and design an experiment to determine the water potential of the cells in this plant tissue. Part 4: Elodea and mystery of the shrinking chloroplasts - why do they seem so withdrawn and leave an empty space in the cell (sigh) when exposed to the mystery solution! Can they be revived with water?. Lab report for Parts 1 through 4. Guideline questions are in the
lab h/o at the very end. Class data - click here..

2) AP Lab # 5 - Cell Respiration Lab: Crickets and peas what could they have in common - well they both respire duh! How much (more or less) does a cricket respire compared to 20 germinating peas? Hmmm care to wager? Investigate the rate of respiration and factors (not again!) that influence rate of respiration of these organisms using respirometers. For postlab ANALYSIS of lab data questions click here (this analysis has 10 questions). For your lab report - there are no guideline questions. You will write the report using the basic checklist and your own "lab report writing skills" that you have so finely honed... and if they are not, read some samples first. Class data here!

3) AP Lab # 4 - Photosynthesis Lab: Spinach leaves - boiled, unboiled; exposed to light and placed in the dark - what difference does it make? Fall leaves and summer leaves - how did the autumn colors develop? And there is more.... Complete the prelab - fill in blanks. Go to LabBench website choose Lab #4, and read through BOTH SECTIONS on chromatography and photosynthesis. Take the quiz and bring answers written on a piece of paper. Print lab handout - click here. Lab handout has postlab analysis questions. Class data click here.

Unit 3

1) Mitosis and Meiosis lab handout - AP Lab #3: Several parts - complete bead simulations of mitosis and meiosis; peek into onion root tips and whitefish blastula to see the stages of mitosis;complete lab bench online activities; investigate independent assortment, crossing over, and linkage via Sordaria recombination and map distance calculation.

2) DNA Fingerprinting lab: AP Lab # 6:Prelab here. the plot thickens and death is imminent. Your classmate Carmen Soret has been betrayed by someone in your AP Biology class! Circumstantial evidence places three suspects in the hands of the police - you will view the FULL details of their court hearing in a video during class. Using RFLPs you will determine the identity of the criminal - CSI style. Postlab questions and overall lab handout here.

3) The glowing bacteria lab: AP lab #6: Insert firefly genes into bacteria to make them glow in the dark! Click here for handout.

4) Nasonia genetics: AP lab #10 and #7: The secret life of bees and birds - is courtship behavior genetically programmed or is it a learned behavior? This part of this lab connects with Unit 8. Mate male and female Nasonia wasps and observe courtship behaviors. Let the Nasonia parasitize the Sarcophagus pupae and then determine the eye color inheritance patterns in these critters....handout here.

Unit 4: Evolution
