5 Questions
What is the purpose of an experiment?
An experiment is carried out to support or refute a hypothesis, or determine the efficacy or likelihood of something previously untried.
What is the importance of experiments in student learning?
Experiments are very important to student learning in the science classroom as they can raise test scores and help students become more engaged and interested in the material they are learning, especially when used over time.
How do experiments provide insight into cause-and-effect?
Experiments provide insight into cause-and-effect by demonstrating what outcome occurs when a particular factor is manipulated.
Give an example of a basic experiment a child might carry out.
A child may carry out basic experiments to understand how things fall to the ground.
How do experiments vary in goal and scale?
Experiments vary greatly in goal and scale but always rely on repeatable procedure and logical analysis of the results.
Study Notes
Experiments
- An experiment is a procedure carried out to support or refute a hypothesis, or determine the efficacy or likelihood of something previously untried.
- Experiments provide insight into cause-and-effect by demonstrating what outcome occurs when a particular factor is manipulated.
- Experiments vary greatly in goal and scale, but always rely on repeatable procedure and logical analysis of the results.
Types of Experiments
- Natural experimental studies exist, where observations are made without interference.
- Informal, personal experiments can be conducted, such as natural comparisons (e.g. tasting a food).
Importance of Experiments in Learning
- Experiments and hands-on activities are essential for student learning in the science classroom.
- Conducting experiments can improve test scores and increase student engagement and interest in the material being learned, especially with long-term use.
- Experiments can be conducted by individuals, like a child, or by teams of scientists, taking years to investigate a phenomenon.
