Miller and Levine 1.1 Review

Modern scientists continue the tradition of the Greek philosophers in their efforts to understand the world around them. They know that the universe consists of objects, organisms, and processes that interact in many different ways, and proper scientific methods can help this understanding. Which two statements state goals of science?

• A goal of science is to use observation, evidence, and experimental testing to understand phenomena in the natural and supernatural world.

• A goal of science is to generate testable explanations for events in the natural world.

• A goal of science is to use the best available tools and methods to gather evidence and conduct experiments that can define and support a permanent database of scientific facts.

• A goal of science is to make useful predictions about natural events, and to understand patterns in nature by using explanations supported by data.

Kari is testing the hypothesis that plants rely on photosynthesis to grow. She conducts an experiment in which she observes the sprouting and growth of bean seeds. The beans are raised either in sunlight or darkness. She records her observations in a data table.

Which statements from Kari’s records convey qualitative data, and not quantitative data? Choose all that apply.

• The beans in the control group have a white spot on day 2.

• The beans in the control group have 1.0 centimeter sprouts on day 3.

• The beans in the control group feel soft on day 2.

• The beans of both groups appear equally green and healthy on day 1.
