Question

You observe your friend rub a balloon on their wool sweater and then stick it to the wall. To investigate, you set up an experiment to test whether other objects will respond in the same way when you rub them against a sweater. What is the test variable in your experiment? The number of times you rubbed the object on the sweater The observation that the object sticks to the wall The sweater you use to rub against the objects The type of objects you are testing in the experiment

Answer 1

Answer:

The test variable is the type of objects.

Explanation:

You're using the same sweater, you're testing if it will stick to the wall in the same way, and you can rub it as many times as you want.

Answer 2

Answer: A test variable is what is being tested for an example like a balloon

Explanation: The independent variable is the one that is changed by the scientist. To insure a fair test, a good experiment has only one independent variable. As the scientist changes the independent variable, he or she observes what happens.
