Scenario 3: Learning About Sea Life In Mr. Miyagi's fifth grade Science class the students had been reading about different salt-water sea creatures. After reading they began to ask questions on how they survive in the ocean. Mr. Miyagi decided to do an experiment to help the children learn more about ocean life. He found it best if the students were divided into five groups. Group A observed a horseshoe crab. Group B observed a sea urchin. Group C observed a snail. Group D observed a spider crab. Group E observed a starfish. After each group had observed the sea organism for 15 minutes, they were asked to record the information about what they discovered. Data included size, shape, color, protection from predators, and how they eat and move. After they had recorded the information, each group was asked to share with the rest of the class what they learned about their creature. The students finally discussed how each sea organism was alike and different. QUESTION: In the scenario, identify the hypothesis and 3 different types of variables or experimental groups. ​
