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 beforegoing into the ocean while the second groupdoes 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 better than no lotion.
Identify the independent variable: Scented Lotion
Identify the dependent variable: How many times each group gets stung..
Identify the other variables Jaydn needs to consider/control during this experiment: amount of lotion, type of lotion, time span they had the lotion on, age of lotion, scent of lotion, how far they are in the water, time span they were in the water, how many jellyfish are in the area, health of jellyfish.
Identify the control group in this experiment: Second group- No lotion
Identify the experimental group:First Group- Sented Lotion
What conclusions might Jadyn draw from this data? That the Scented lotion prevented most of them from getting stung by the jellyfish.
What recommendations might you suggest for further study or for improvement? Changing the type of lotion, The time of day, the amount of jellyfish in the area. You could collect some jellyfish and put them into a pool of salt water, and have the people get into the pool.
