The Scientific Method
Fill in the Blank
1. A systematic approach to problem solving is called the __________________.
2. The first step of the scientific method is to state the __________________ or ask a _________________.
3. Before you create a hypothesis, you must gather __________________, and is known as the second step of the scientific method.
4. Before experimenting, you must state the __________________, which is the third step of the scientific method. A hypothesis is a suggested __________________to a scientific problem.
5. In which step of the scientific method does the scientist test their hypothesis? __________________
6. A step by step plan for your experiment is called a __________________.
7. In an experiment there are two variables, the __________________ variable, and the __________________ variable.
8. The scientist changes the __________________ variable, and the __________________ variable responds to the __________________ variable. The purpose of the independent variable is to have a variable that gets__________________.
9. A controlled experiment has two different types of set-ups…the__________________ set up, and the __________________ set up. __________________ are the factors that remain the same in an experiment.
10. In an experiment, the setup without the independent variable is the__________________.

The Scientific Method in Action
A scientist wanted to see if fertilizer would affect the growth of tulip flower plants. The scientist put both tulips in the sunlight for the same amount of time, and gave them an equal amount of water each day. The scientist gave one of the tulips fertilizer and didn’t give it to the other plant. She compared the growth of the tulip without fertilizer to the tulip with fertilizer. The tulip with fertilizer was much taller.
