What is Science???

Johnny heard that he can show the way the Earth is tilted by studying the length of daylight. Every day Johnny would calculate the time of the sunrise and the sunset to determine the length of the day. After collecting this information every day for a year, what would be his next step?

• Form his hypothesis

• Write his conclusion

• Analyze the data he collected

• Create a question

Brian was flying to Orlando. When he took off in his hometown it was raining. Brian noticed the clouds were dark when the plane was taking off the ground. But, once the plane got above the cloud cover, he noticed the clouds were white. If Brian was to create an experiment about this observation, what would be his next step?

• Form a question

• Create an experiment

• Analyze data

• Create a conclusion

Analyze the data in the chart. If you were to add a 7th subject, according to the data, what would you infer to be the relationship between the pupils in the light and dark?

• Pupils in the light would be larger than in the dark

• There would be no change in the pupil diameter

• Pupil diameter would be larger in the dark than in the light

• There is not enough information to make this inference

The first classification of life was presented by Aristotle who indicated that all life was either Plant or Animal. Now in science we have 7 levels of classification. Why was science allowed to change?

• Science is unchangable

• Science is always changing as new technology and information is presented.

• Science cannot be disproven

At one time scientist believed that hippos were related closely to pigs due to physical features. But now we know they are closer related to whales and dolphins. How is this change possible?

In many experiments that deals with reactions in liquids, water is used as one of the subjects the experiment. Describe the importance of doing the experiment to water.

• It is what you change in the experiment

• It is what is being affected and changed in the experiment

• It is used to make a negative result

• It allows for comparison to measure the changes in the experiment
