Which type of shoe makes you run faster, Nike or Adidas?

Examples of scientific questions and hypotheses

If one of the variables cannot be varied, it is impossible to conduct an experiment. Write 3 more testable questions about the tomato plant by following the steps in question 4. Testable: Does wearing a sweatshirt during gym affect how warm you get? Just remember: Testable questions do not ask about things that are NOT considered to be phenomena! Updated April 24, By Yvonne Garcia A testable hypothesis is one that can be used as the basis for an experiment. How do you turn a topic into a testable question? If your question does not require collecting data qualitative and quantitative observations , then your question is NOT "testable". How does a paper airplane fly? What is NOT a testable question? The process could be repeated several times to create enough data to determine whether there is a correlation between water temperature and how long it takes to freeze. Something that we will measure in an experiment 5 What is an Independent Variable? If more than one variable is changed, the results are inconclusive. Testable: Does doing tests affect student success? The water temperature and the time it takes to freeze are measurable, and one of the variables, the temperature of the water, can be varied.

The dependent variable — the thing we would measure. How do you turn a topic into a testable question? For example, you could boil water, pour it into ice cube trays and put the trays in the freezer, then note the time it goes into the freezer and how long it takes to freeze.

writing testable questions practice

This can be in the form of a question, such as, "Which freezes faster, hot water or cold water? Also consider how to keep all other variables, such as the size of the ice cube trays and their placement in the freezer, constant so that only the temperature of the water changes.

Independent variable Dependent variable 16 Problem 1 Non-Testable: What happens if you wear a sweatshirt during gym?

how to write a hypothesis

You could then take cold water and do the same thing. Watch the video below on how to write testable scientific questions for investigation!

Non testable questions

Consider how you would test the variables to explore your observation. If more than one variable is changed, the results are inconclusive. In other words, a testable question can only be answered by gathering evidence. Watch the video below on how to write testable scientific questions for investigation! How do you turn a topic into a testable question? Follow the steps for turning the topic "Cafeteria Pizza at MS 88" into a testable question. What are the two parts of a controlled experiment that are in every testable question? Another way to think about is in terms of a controlled experiment. Testable questions are not related to personal preference, moral values, the supernatural, or things that cannot be measured. Decide what you are going to measure For example: Distance the plane will fly Length of time the plane stays in the air 20 Make the Question Testable Now select decide what will be changed. Testable questions examine cause and effect relationships. How does a paper airplane fly? The water temperature and the time it takes to freeze are measurable, and one of the variables, the temperature of the water, can be varied. The process could be repeated several times to create enough data to determine whether there is a correlation between water temperature and how long it takes to freeze. If the variables cannot be measured, the hypothesis cannot be proved or disproved.

In each case, you would measure the temperature of the water before putting it into the freezer. To write a testable hypothesis, it is important to consider how it will be tested and what makes for a valid experiment.
