Days to Teach:
one week to complete the lab
Teaching Tips / Activity Overview:
In order to avoid wasted class time, students can learn about Domain Bacteria while they are working on the lab. The lab work will take about a week, but will not take an entire class period every day. During waiting periods, students can be researching information about Domain Bacteria. Have supplemental activities they can work on like charts and concept maps to compare and contrast Archaea to Bacteria.
- Completion of known lab- using Ecoli to go through all the lab procedures (days 1 and 2)
- Start thinking about lab design (days 1 and 2)
- Lab design (second part of day 2)
- Collect bacteria (second part of day 2)
- Begin inquiry lab testing (days 3-5)
- Work on lab write-up or poster presentation (days 3-5)
- Work on supplemental activities about Domain Bacteria and Domain Archaea (days 3-5)
- Work on lab write-up or poster presentation (due one week after lab work in complete) There will be no more class time to work on the lab write-up or poster presentation after day 5.
- If you are short on time, the following can be made ahead of time:
- Agar plates
- Master mix for PCR (completed before start of class)
- Agarose gels
- Do not give the students too many ideas about what they can test. This should be an inquiry lab and you want the students to be engaged and creative.
- Make sure you are clear about lab safety before students complete this lab. (i.e. where to put contaminated materials)
