What would be the best way for Tim to turn this demonstration into an experiment?
What would be the best way for Tim to turn this demonstration into an experiment? He could add different amounts of vinegar to the same amount of baking soda and time how long it bubbles each time.
What are the independent and dependent variables in Sam’s investigation?
During an investigation, Sam observes the number of hummingbirds that come to his large bird feeder at different times of day. Time is the independent variable, and the number of birds is the dependent variable. The type of bird food is the independent variable, and the number of birds is the dependent variable.
What statement describes the independent variable?
Answer: An independent variable is exactly what it sounds like. It is a variable that stands alone and isn’t changed by the other variables you are trying to measure. For example, someone’s age might be an independent variable.
Which of the following best describes the independent variable in this research design soil?
Which of the following best describes the independent variable in this research design? The sample of material chosen as the potential container material is the variable being tested, so it is the independent variable. Which of the following is the correct order of soil particles in order of increasing size?
What variables should the scientist control in the experiment?
In a controlled experiment, an independent variable (the cause) is systematically manipulated and the dependent variable (the effect) is measured; any extraneous variables are controlled.
Which description best defines a test independent variable in a scientific experiment?
An independent variable is defines as the variable that is changed or controlled in a scientific experiment. It represents the cause or reason for an outcome. Independent variables are the variables that the experimenter changes to test their dependent variable.
What do experiments actually do in regards to hypothesis?
When conducting scientific experiments, researchers develop hypotheses to guide experimental design. A hypothesis is a suggested explanation that is both testable and falsifiable. You must be able to test your hypothesis, and it must be possible to prove your hypothesis true or false.
What is the best description of a dependent variable?
A dependent variable is what you measure in the experiment and what is affected during the experiment. The dependent variable responds to the independent variable. It is called dependent because it “depends” on the independent variable.
Which is true about a dependent variable in a research study?
Which is true about a dependent variable in a research study? It is: the cause of changes in other variables in a research study.
How do I run an experiment to test my hypothesis?
Run an experiment (a way to test this hypothesis by changing some things in your product or service to see if those changes achieve a predicted level of improvement) 1. Observe In this example, we want to improve our retention rate.
How are hypothesis used to design experiments?
Hypotheses, which are proposed explanations for scientific observations, help us properly design experiments because experiments are used to test those hypotheses. Experiments are designed based on the measurable variables defined in a given hypothesis. But this is only the first step.
What is a good hypothesis for an experiment with three foods?
You have three different foods that you can test in this experiment, and a good hypothesis for your experiment might be: When the goldfish are offered the three different foods, they will prefer food A. This is a good hypothesis because it meets a number of criteria. First, it’s a clear statement that is testable.
