The Case of the Sleeping Frog The following paragraphs tell about an investigation carried out by a life science student named Kara. See if you can put the paragraphs in the correct order. Place the number 1 next to the paragraph that describes what you think happened first. Put the number 2 beside what you think happened next and so on. Then answer the question. __ Kara obtained two liter jars and placed a live frog in each.She inserted a thermometer through a hole in the screened lid of each jar. She then placed each jar inside a larger jar. Kara filled one of the larger jars with ice cubes.The ice cubes surrounded the smaller jar that held the frog. Kara did not put any ice cubes in the other set of jars. __ Kara went to the library to find out about hibernation. She read several articles on the topic. __ Kara noted that in the jar with the ice cubes, the frog began to move more slowly and finally seemed to go to sleep. The frog's rate of breathing became slower too. These changes did not occur in the other jar. When the ice was removed from the first jar The frog gradually became more active. __ Every 30 minutes Kara recorded the temperature inside each of the two smaller jars. She also recorded the breathing rate of the frog and other observations about the frog's appearance and behavior. __ After reading about the topic, Kara made an educated guess. She guessed that she could make a frog hibernate by making it cold. Questions: 1. What was the problem that Kara wanted to investigate? __ __

Answer

Kara wanted to investigate whether she could induce hibernation in a frog by lowering its temperature. Explanation 1. Identify the initial action Kara went to the library to find out about hibernation. She read several articles on the topic. 2. Formulate a hypothesis After reading about the topic, Kara made an educated guess. She guessed that she could make a frog hibernate by making it cold. 3. Set up the experiment Kara obtained two liter jars and placed a live frog in each. She inserted a thermometer through a hole in the screened lid of each jar. She then placed each jar inside a larger jar. Kara filled one of the larger jars with ice cubes. The ice cubes surrounded the smaller jar that held the frog. Kara did not put any ice cubes in the other set of jars. 4. Conduct observations Every 30 minutes Kara recorded the temperature inside each of the two smaller jars. She also recorded the breathing rate of the frog and other observations about the frog's appearance and behavior. 5. Analyze results Kara noted that in the jar with the ice cubes, the frog began to move more slowly and finally seemed to go to sleep. The frog's rate of breathing became slower too. These changes did not occur in the other jar. When the ice was removed from the first jar, the frog gradually became more active.
