We will sample bacteria from around our school.
HYPOTHESIS:
Create a hypothesis about what area of the school will yield the fastest growing bacteria and the most number of colonies.PROCEDURE:
Use agar plates and q-tips to sample different surfaces around our school. Store the plates UPSIDEDOWN in a secure location in the classroom. Note where you found the sample
OBSERVATION
Next, create a data table showing in the following columns
1. names
2. a. location of sample
2.b. is this a high traffic location for human contact?
2c. is this a dry, sticky, wet, warm, cold location, or don't know?
3.a count the number of colonies
3b. and their relative size of colonies (estimate size of each dot or circle diameter based on petri dish size
4. colour of colonies
5. Any mold sample?
Note that a nil result tells you something too!
ANALYSIS
1. Tell me some patterns that you are noticing in the collection of these samples.
2. Which locations are yielding the most samples.
3.Why might some samples yield more bacteria or faster growing bacteria?
4. What are some limitations of this study and some sources of experimental error?
CONCLUSION
Write a well reasoned conclusion based on your observations.

EVALUATION IS OUT OF 25 IN TOTAL ...create a ppt for this assignment!
5
presentation is out of 5. for 5/5 it is typed with illustrations or photos and emailed to for 4/5 it is pretty good but there are a few spelling mistakes. for 0-3 out of 5 it is in pencil or messy.
10
Clear writing is out of 10. for 9/10 or 10/10, it is written with no English mistakes and it clearly communicates each part of the lab report. 7-8/10 it is very well written for 5-6/10 some parts are not so clear and the reader must guess what you are trying to say. 0-4/10, it is minimally communicating what happened
10
Paragraphs are insightful and your observations are well done. this is out of 10.
9-10/10, your observations and conclusions are well written and logical. It is brilliant
7-8/10 your observations and conclusions are very well done
5-6 your conclusions don't really logically follow from your results
0-4 your conclusions are not relating to your results at all
