Scientific Method and Engineering Design

Scientists conduct experiments to answer their questions about the world. They follow a set of procedures, known as the scientific ______.

First, scientists ask a testable question based on their observations. Then, they do ______ to learn about the topic they’re investigating.

Scientists form a hypothesis, or an educated guess, about what they think will happen based on the patterns they’ve seen. This is actually in the form of a cause-and-effect relationship: if we change _____, then _____ will happen.

Scientists design and conduct an investigation to test the hypothesis. This usually involves changing one variable to see how it affects another. The experiment might involve several ______.

During the experiment, scientists use tools to collect ______ that will help answer their question.

As we learn new information, our scientific knowledge ______.

Scientists organize and analyze the data to determine the answers to the testable ______

Scientists use the data to form ______ and support arguments about the problem they studied

Scientists share the results and conclusions with ______

Every experiment involves ______

The factor that is changed by the experimenter is the independent ______

The factor that changes because of the independent variable is the dependent ______

Other factors that can affect the data and must be kept constant are called ______

Scientists can collect qualitative or quantitative ______ during the experiment

Qualitative data is observable through the senses, like color, texture, and ______

Engineers use scientific knowledge to solve problems by developing objects, tools, processes, and ______
