Procedures (step by step instructions someone would follow in order to do this experiment):
This experiment uses the scientific method; include all of the steps in the think.

Answer 1

A scientific experiment is conducted to test a hypothesis by manipulating an independent variable and observing the effect on a dependent variable, while controlled variables remain constant. The scientific method includes formulating a hypothesis, designing an experiment with clear variables, collecting data, and verifying results by repetition. Proper recording and clear presentation of the experiment are essential for replication and verification by peers.

Step-by-step explanation:

Components of a Scientific Experiment

An experiment is a procedure carried out to support, refute, or validate a hypothesis. Experiments provide insight into cause-and-effect by demonstrating what outcome occurs when a particular factor is manipulated. In the context of the scientific method, the steps to create a solid experiment include:

1. Observing an event and identifying an answerable question about the event.
2. Formulating a hypothesis that offers a tentative explanation.
3. Designing an experiment to test the hypothesis, which involves identifying independent, dependent, and controlled variables.
4. Collecting and accurately interpreting data.
5. Drawing conclusions based on the results.
6. Determining the validity of the hypothesis as correct or incorrect.
7. Verifying results through repetition.

In any experiment, the independent variable is the factor that the scientist manipulates, while the dependent variable is the factor that is observed and measured, changing in response to the independent variable. Controlled variables are the factors that are kept constant to ensure that the effects observed are due to the manipulation of the independent variable only.

During the experiment, a scientist must:

• List all materials required.
• Describe procedures detailutely to allow replication by others.
• Run control tests alongside the experimental tests.
• Keep detailed records of all observations and results.

Presenting the work in a specific layout improves clarity and enables peer verification. This openness to scrutiny and potential disproof is a core tenet that distinguishes science from non-science.
