Fair Testing
Conducting a fair test is one of the most important ingredients of doing good, scientifically valuable experiments. To insure that your experiment is a fair test, you must change only one factor at a time while keeping all other conditions the same.
Scientists call the changing factors in an experiment variables.
We brainstormed all the different things we could change (vary or measure). We then decided on two things we could change eg light/dark and hot/cold. We then decided on how we would measure what we saw happening. Each of us asked a question and recorded this on our sheet. Over the next few weeks we will watch what happens and record our measurements. Lastly we will write what happened.
We will let you know how things are going next week.
