Instructional Ideas
- Create balanced groups for this activity, with a mixture of abilities, of two to four learners
- Extend the lesson by assigning research projects regarding drugs derived from marine invertebrates
Classroom Considerations
- Lab experiment requires prior knowledge of agar preparation and assembly of Petri dishes with agar for testing purposes; increase the time allotted for this lesson for classes with little to no prior knowledge
- Provide computers with Internet access to groups for research purposes
Pros
- Procedure is detailed, but it provides clear evidence of inhibited bacterial growth via introduction of plant extracts
- Plan includes a wealth of information and all printable materials
- Multiple opportunities for extension from the basics found in the additional resources
Cons
- None
