Jadyn and her family have a beach house in Galveston. Jadyn loves spending most of her summers there but always seems to get stung by jellyfish. This summer, she wants to have a good time without having to worry about the jellyfish. Jadyn wonders if jellyfish will sting her legs if she puts scented lotion on them. She believes the scented lotion will keep the jellyfish away buts wants to know for sure before she spends her allowance on expensive lotions.
Jadyn decides to conduct an experiment and recruits 16 of her friends to help out. She divides them into two groups of 8 each.One group spreads a scented lotion on their legs before going into the ocean while the second group does not use any lotion. The results of her study can be found in the data table below:
Group 1 with Lotion
Group 2 without Lotion
Stung
1
7
Not Stung
7
1
Complete each of the following:
Identify Jadyn's hypothesis: Scented lotion will keep the jellyfish away instead of without lotion.
Identify the independent variable: Scented lotion.
Identify the dependent variable: How much more people get stung without having scented lotion on.
Identify the other variables Jaydn needs to consider/control during this experiment: Brand of lotion, scent, how much lotion, is the lotion waterproof, their skin tone, how far they go into the ocean, and the type of jellyfish.
Identify the control group in this experiment: The group that does not have any lotion on.
Identify the experimental group: The group with the lotion on.
What conclusions might Jadyn draw from this data?Jadyn's conclusion from the results might be that the scented lotion does help to not get stung by jellyfish.
What recommendations might you suggest for further study or for improvement?An improvement could be to let the one group with no lotion in a tank with the same species of jellyfish, have them stay in the tank for a while. Then put the second group in with the lotion on in the same tank, and have them stay in the tank for the same amount of time. This will eliminate any problems with variables. Making sure that they are the same. Like the tempature of water, the kind of jellyfish, the amount of time in the water, the depth of water, etc. It will all be constant.
