Formulating Hypotheses: Intro to Scientific Method

What is the learning intention mentioned in the document for formulating hypotheses?

• To understand the importance of hypotheses in science.

• To describe the structure of a hypothesis.

• To list the different types of scientific investigations.

• To analyze the outcomes of an experiment.

According to the content descriptor, what are students expected to do with questions, problems, and claims in scientific investigations?

• Disprove them using scientific methods.

• Identify and investigate them scientifically to make predictions.

• Memorize them for future reference.

• Share them with peers for collaborative research.

What is the success measure for a student learning to formulate hypotheses?

• To accurately record data during experiments.

• To develop a hypothesis to make predictions of expected results from an investigation.

• To present the hypothesis in a scientific conference.

• To publish a paper on the formulated hypothesis.

What is a prediction in scientific research?

• A guess about what might happen

• A reasoned statement about what will happen, based on scientific knowledge

• A random outcome of an experiment

• A summary of an experiment's results

What is a hypothesis?

• A simple question that can be answered with yes or no

• A detailed report of an experiment

• A reasoned prediction that can be used to create a testable experiment

• A collection of data from various experiments

Which of the following is considered primary data?

• Data collected by reading scientific journals

• Data you have collected yourself through observation or experimentation

• Data collected from online sources

• Data quoted from textbooks

What is secondary data?

• Data you have imagined or hypothesized

• Data collected through your own direct experiences

• Data others have collected through observation or experimentation

• Data that is not relevant to the hypothesis

Why must you be able to explain your reasoning when making a prediction?

• To ensure the prediction is based on personal beliefs

• To make the prediction more convincing to others

• To follow the scientific method and support the prediction with logic

• To guarantee the accuracy of the prediction

What is a dependent variable in the context of an investigation?

• The variable that is changed to observe its effect on the outcome

• The amount of water a plant receives

• The factor that is measured during an experiment

• The number of hours spent playing soccer

What does the independent variable affect in an investigation?

• The hypothesis

• The dependent variable

• The control group

• The experimental group
