Practice Writing a Lab Report Hagrid has just found out that Hogwarts is holding a dog competition in a few months, and the winner gets a lifetime supply of dog food! He really wants to win, but he thinks that Fluffy, his dog, needs to lose some weight first in order to pass the agility test. So, he decides to conduct an experiment with the purpose of testing the effects of different types of food on Fluffy’s weight. Hagrid thinks that if Fluffy is given a diet of raw whole organic foods, then he will lose weight. He creates three groups of food types. He is going to observe Fluffy after eating each of the food groups for 1 week and measure his weight. Group A is his normal diet of whatever Fluffy catches to eat. Group B is a diet of whole organic foods mostly consisting of vegetables and low fat grass fed meats. Group C is Purina One dog food. Hagrid measures Fluffy’s weight after a week of eating each type of food group. He feeds Fluffy 25 pounds of food twice a day at the same time of day. He also weights Fluffy at the same time of day on the same scale. He does not give Fluffy any other food during the experiment. After a week of eating Group A, Fluffy’s weight did not change. After a week of eating foods from Group B Fluffy lost 5 pounds. After eating foods from Group C Fluffy gained 10 pounds with a net gain of 5 pounds over the previous week. Data and Observations: Group A Normal diet Group B Raw whole organic foods Group C Purina One Pounds gained or lost in 1 week 0 Lost (-5) Gained (+10) Instructions: Use the information above to complete the practice lab writing assignment below.
