Scenario+8

The Mice

A scientist observed that mice fed seeds appeared to grow more than mice fed leafy green and yellow vegetables. The scientist wondered if this might be caused by the higher concentration of protein in the seeds than in the vegetables. He decided to conduct an experiment to find out. The scientists got 200 mice of the same age, size, and gender and divided them into two groups of 100 mice each. He weighed each and fed Group A- a diet low in protein and Group B- the same food except he added a protein supplement. Both groups received the same amount of food each day. He checked the mass of each mouse each day and kept accurate records for 14 days. The results from his experiment are found in the data table below:
 * =  ||= Group A - diet low in protein ||= Group B - diet high in protein ||
 * = Average mass gained ||= 12 grams ||= 8 grams ||

Complete each of the following:
 * 1) Identify the hypothesis: Mice fed with low protein in their diet will gain a higher average mass than the mice fed with a high protein in their diet.
 * 2) Identify the independent variable: The independent variable is the amount of protien the scientist is putting in their diet because on group (A) is getting a low protien in their diet, and the other group (B) is getting a higher amount of protien.
 * 3) Identify the dependent variable: The dependent variable is the mice in which are being fed the different diets.
 * 4) Identify the other variables the scientist needs to consider/control during this experiment: Some other Variables they could consider trying a medium protein for an additional group, how much the fed the mice, where each (high, and low) protien is being stored, keep the brands of fed the same, keep the same type of food for the mice the same just make sure one of the feeds is high in protien and one low in protien, also make sure the mice are all getting the same amoung of exercise, and same amount of sleep and keep the mice all in the same environment, with the same amount of sunlight.
 * 5) Identify the control group in this experiment: The Control group is Group A-.
 * 6) Identify the experimental group(s): The experimental group is Group B-.
 * 7) What conclusions might be drawn from this data? The group with the diet in low protein has a higher average mass than the group of mice with the high amount of protien in their diet.
 * 8) What recommendations might you suggest for further study or for improvement? Some recommendations are that they could have a wider variety of food for the different mice, or a different amount of protien for each and every group.
