What is the fault in this design of experiment to catch fruit flies?
Fault in the design is…
- Keeping all three bottles at the same place that too beside a very clean dustbin
- Tomato used were fresh and they were not full ripe but kinda soft and red from one side and little yellowish at other side as u can see in the bottle
- Fruit flies are attracted to fermenting fruits so… Should have used something that was stinks a bit like rotten tomato or banana etc
- Should have kept these bottles at different place to trap flies
Design for this experiment was…
Aim: To trap native fruit flies from Bandra, Mumbai
Objective: To trap fruit flies using Tomato (You can try with any fruit, curd, butter milk & vinegar too)
Research question: How to trap fruit flies at home
Hypothesis: Would get approximately 20 flies in 3 bait bottles
Materials - 3 empty bottles (for bait), 1 empty bottle (for transferring to media), tomato (or any other fruit),
Method:
- Put pieces of tomato in 3 empty bottles
- keep these 3 bottles near the dustbin
- Cover the mouth of the bottle when you see many fruitflies
- transfer the fruitflies in an empty bottle
- now transfer the fruitflies from empty bottle to the media bottle
Precaution: be careful while transferring the fruitflies as they might fly away
Design: Check the bottles 2 hours after keeping near the dustbin
Expectations: there would be at least 5 fruitflies in each bait bottle
Observation: Got no flies first day and only 2 flies on second day
Will work on the design and try to improve it!
