True or False: In an experiment, you must always have a control group, which is the group where no details/characteristics are changed, so that you have something to compare your experimental data to.

• True

• False

True or False: An experiment is still accurate and valid if you change more than one detail or characteristic (variable) at a time to see how the outcome is effected.

• True

• False

True or False: Only one detail or characteristic (variable) should be changed at a time to get more accurate data of how these variables effect an outcome.
