Scientific Knowledge Assignment

What does it mean to say that science is a "systematic" process?

Science is a systematic process, which means it follows a careful method that involves observation and experimentation. Through experimentation, information is collected that supports or refutes a scientist's hypothesis.

Which statements best describe science? Check all that apply.

Science is supported by facts and processes. Science involves observation and experimentation. Science continually changes and is constantly updated.

Explain how scientific knowledge develops through making observations about the natural world.

Scientific knowledge develops through making observations about the natural world. An observation may generate a scientific question, which may lead to a hypothesis. The hypothesis can be tested through experimentation. The results of experimentation lead to changes in scientific knowledge.

Which is a component of pseudoscience, but not science?

beliefs

How can a scientist ensure that his or her data are reliable?

by repeating trials during an experiment

Explain how creating a model provides a practical solution for some scientific research.

Models are simplified representations that make it possible to study very large, very small, or very complex objects or systems.

The Flat Earth Society states Earth is flat and shaped like a disc, as pictured, despite scientific evidence that demonstrates Earth is shaped like a sphere. Are the statements of the Flat Earth Society an example of science or pseudoscience? Explain your answer.

This is an example of pseudoscience. It is based on beliefs rather than facts. In addition, it has not been updated based on scientific information indicating that Earth is shaped like a sphere.

Match each statement with the characteristic of scientists. In chemistry class, Roberto sees that traces of lithium makes a flame appear bright red. Roberto wonders if the presence of other elements also affects the color of a flame. Roberto's friend tells him the color of a flame cannot be changed, but Roberto is still unsure. Roberto designs an experiment to test flame color in the presence of different elements.
