Mosquitoes, Be Gone!

What scientific claim did the young scientists make regarding mosquitoes? *

6 points

A. The young scientists claimed that mosquitoes are easily repelled using DEET and over the counter products.

B. The young scientists claimed that plant extracts from the Bixa orellana plant may repel mosquitoes and kill mosquito larvae.

C. The young scientists claimed that citronella plants and candles are not effective in repelling mosquitoes.

D. The young scientists claimed that mosquito larvae is no affected by the extracts of the Bixa orellana plant.

This is a required question

What scientific evidence do the scientists have to support their claim? *

5 points

A. Candles that were made using the Bixin, orellina, resin, and volatile oils prevented the scientists from being bitten by any mosquitoes during their experiment.

B. The young scientists applied DEET bug sprays to one group of 15people and another group of 15 people did not receive any bug spray. The group who received bug spray had fewer than 5 mosquito bites during a 2 hour period. The (control) group with no bug spray had 37+ mosquito bites after a 2 hour period.

C. After applying the individual extracts to the larvae containers, significant numbers of larvae did not survive.

D. After separating 4 extracts from the seeds (bixin, orellina, resin, and volatile oils), the scientists tested each extract on mosquito larvae. None of the individual extracts killed many (if any) mosquito larvae in their experiment. Using all 4 extracts together, killed all of their mosquito larvae sample (about 70-100 larvae). Additionally, the scientists added the extracts to candle wax. When the candle was list, there seemed to be fewer instances of biting insects (adult mosquitoes).

Do you think that their scientific explanation is correct? Why or why not? (you may choose more than one answer for this question) *

6 points

A. Yes- I believe the young scientist claim that bug sprays are sufficient deterrents for mosquitoes. The young scientists conducted a thorough investigation and their evidence supports their claim.

B. No- The scientists did not conduct an investigation that is thorough enough to support their claims.

C. Yes- I believe their scientific explanation is correct because the sample of larvae that was exposed to all 4 extracts did not survive when exposed to those extracts. I do not believe the claim that the extracts used in scented candle form was accurate.

D. No- I do not believe their claim/explanation. The scientists' claim that the candle wax with extracts is able to repel mosquitoes is not a valid claim. They did not conduct a thorough investigation on this claim and more research is needed to support this claim.

This is a required question

What do you think needs to be studied further to fully support the scientists' explanation? *

6 points

A. A formal experiment is needed. Numerical data should be recorded and analyzed.

B. The scientists did not have enough experimental groups in their investigation. This experiment should be done again with more experimental groups.

C. A formal experiment should be conducted and data should be reported regarding the reliability that the candle wax with extracts to repel mosquitoes. Additionally, another experiment should be conducted to determine if all 4 extracts are required to kill mosquito larvae (as opposed to 2 or 3 combined extracts).

D. The scientists should use a larger control group and experimental group to test the efficiency of the DEET bug spray in various areas of the metroplex.
