Sometimes you have a question. You can do a test to find out. In a fair test, you change one thing. You keep everything else the same.
Try it together
Mia tests two paper towels. She drips the same water on each one. She watches and sees towel B soaks up more. Now she can answer her question: towel B works best.
Good to know
Change only one thing at a time. If you change two things, you cannot tell why.
Test one thing, watch closely, then answer your question.
