Testable vs General Interest Science Questions Quiz

Questions and Answers

What is a testable question?

It is a question that can be answered through hands-on investigation.

What is the difference between a 'general interest science question' and a 'testable question'?

A testable question is about changing one thing to see how it affects another object.

What does this article tell you to use in order to make a good question?

Make a hypothesis about the outcome based on the research or their own knowledge.

Study Notes

Testable Questions

A testable question can be answered through hands-on investigation.
It involves manipulating one variable to observe the effect on another.

General Interest Science vs. Testable Questions

General interest science questions are broader, while testable questions are specific and focus on causal relationships.

Creating a Good Hypothesis

Formulating a hypothesis should be based on existing research or personal knowledge.
A hypothesis should be clear and measurable, avoiding ambiguous language such as "may."

Observations vs. Inferences

Observations are factual data collected through senses.
Inferences are interpretations or conclusions drawn from observations.

Qualitative vs. Quantitative Observations

Qualitative observations are descriptive and derived from sensory data.
Quantitative observations involve numerical data obtained through instruments (e.g., rulers).

Writing Effective Hypotheses

A hypothesis should be definitive, stating what is being tested and predicting an outcome.
Effective hypotheses must be measurable to allow for experimentation.

Variables in Experiments

Only one variable should be changed at a time in an experiment to isolate effects.

Importance of Sufficient Sample Sizes

Utilizing multiple subjects in both control and experimental groups enhances the accuracy of results.
Larger sample sizes provide a better basis for conclusions.

Data Presentation Methods

Graphical data can be presented using various methods, including defining questions, forming hypotheses, gathering resources, and planning data collection.

Reasons for Unexpected Data Results

Discrepancies between data and hypotheses could arise from an incorrect hypothesis or flawed data.
