The short experiment appears to defy gravity like magic, but don’t be concerned, Youngsters can Learn the way science makes it perform!
A Manage is often a neutral “reference point” for comparison that means that you can see what shifting a variable does by evaluating it to not shifting anything. Trustworthy controls are sometimes quite not easy to acquire. They are often the hardest Section of a project. Without a Management You can't make sure that altering the variable will cause your observations. A number of experiments that features a Management is termed a “controlled experiment.”
