All groups were reared at 300C, 75% humidity, 12 hours of sunlight, and given unlimited water supply. Twigswith leaves were also added to the cages to make them more comfortable. .(All other environmentalconditions were the same for all groups) This experiment was repeated (5 replicates) for statistical accuracy.Data Table: Number of egg cases produced with different percents of Vitamin CCage # #1 #2 #3 #4 #5Amountof Vitamin C 0% 10% 20% 30% 40%# of egg casesReplicate 1 10 20 30 40 50Replicate 2 10 21 19 27 34Replicate 3 10 20 30 40 5Replicate 4 10 10 10 15 23Replicate 5 10 9 8 0 0I.

Experimental Group(s): ATTACHMENT PREVIEW Download attachment HW SM Praying Mantis (2).pdf HOMEWORK 1 Scientific Method Initial Observation: Praying Mantis in Florida has a higher reproductive cycle than Praying Mantis in Illinois. Background Information: ◊ Studied climatic factors between Illinois and Florida when Chinese mantis are present – no major difference during the summer ◊ grasshopper/crickets are the main food items eaten by praying mantis √Analysis disclose that Florida grasshopper/crickets contain larger amounts of vitamin C than Illinois ones ◊ Library research suggests that vitamin C may affect the reproductive cycle in other insects ◊ Library research also allowed us to determine the type of praying mantis that lives in our area (the Chinese mantis = CM) Inference? Vitamin C increases the reproductive cycle in praying mantis Hypothesis: (IF, THEN form) If vitamin C increases the number of egg cases laid in Chinese mantis, then as the amount of vitamin C is increased in the diet of Chinese mantis the number of egg cases laid will increase Design Experiment: purpose is to test the hypothesis 500 Chinese mantis (250 males/250 females) Randomly (without bias) divide into 5 groups (50 males & 50 females) Group #1 #2 #3 #4 #5 #of CM 100 100 100 100 100 Amount of Vitamin C 0% 10% 20% 30% 40% All groups were reared at 300C, 75% humidity, 12 hours of sunlight, and given unlimited water supply.
