Review of Venus Flytrap Experiment Presentation

Investigate experimentally how Venus flytrap catches and digests prey. Reviewer Chris Kalemkeris analyzed the strengths and weaknesses of the presentation. Some key points include the lack of hypothesis, variables, and method details, as well as the absence of labeled pictures. The opponent highlighted missing measurements, unfocused questions, and redundancy in discussing quantitative results. Questions raised relate to chemicals used, fly size, needle pressure, and origin of flytraps.

Presentation Transcript

1. Venus Flytrap Topic 9 Reviewer: Chris Kalemkeris

2. Task Investigate experimentally how Venus flytrap (Dionaea muscipula) catches and digests its prey. 1

3. Reporter Strengths Weaknesses Showed how prey is captured No hypothesis,variables,method, materials no errors Visual aid is present-videos showing method The change in the chemical composition not explained Explains theory-5 phases Didn t fully focus on experiment Tested 5 traps Pictures not labelled 2

4. Opponent Strengths Weaknesses Pointed out the absence of some measurements and missing data from the presentation Unfocused questions in discussion Pointed out lack of tables Wrongly stated that reporter didn t mentioning that the plant is a carnivore Questioned control of variables(size of fly) and how they affect the results (time taken to digest) redundant focus on the quantitative results Didn t question number of plants used /trials 4

5. Questions asked by Opponent-Discussion Do you know the chemicals that were used to feed the plants? Fly Size Needle Pressure control Origin of the Flytraps 4

6. Suggestions For Reporter: Conduct more trials (with a variety of insects, and a larger quantity of the plants) Try to focus more on observations made rather than general theory For Opponent: Focus more on the errors in the reporter s experiment and question reliability 1
