Scientific Method and Experiment Design

The video tutorial introduces the scientific method, emphasizing its role in ensuring consistent scientific tests. It discusses the Science Olympiad competition, focusing on experiment design using provided materials. The tutorial uses toy cars to explain independent and dependent variables, highlighting the importance of testing and measurement. The session concludes with homework instructions and a reminder to keep the worksheet for future use.

What is the primary purpose of the scientific method?

• To ensure creativity in experiments

• To make tests consistent and reliable

• To reduce the number of experiments

• To increase the speed of experiments
