- write a summary Introduction: The introduction explains the purpose and objectives of the experiment. A goodway to approach this section is to attempt to provide the reader with background, discussing thewhat and why of the experiment. Beginning with a bit of prior knowledge on which the experimentis based, you then try to explain the purpose of the experiment and why it was conducted in a certainway. Often, background information and purpose of the experiment will be found in your sciencetext. The introduction is also the place where you state your hypothesis.Procedure (sometimes called Materials and Methods): This section is importantas it explains to the reader exactly what you used to perform the experiment and how you did it. Itis highly detailed so that another scientist could reproduce your experimental methods in order toobtain the same results and gain extra data.

- The variable is a part of the experiment that varies or changes. True Falsearrow_forwardThe 'control group' is an essential component of an experiment. This is because 1. A control group allows one to determine if a particular result is due to the experimental variable. 2. No, it's not essential in experimentation. A control group is not always necessary it depends on the experiment. 3. A control group allows for multiple variables to be tested at the same time. 4. A control group is required for the development of a prediction.arrow_forwardCompare and contrast random and systematic experimental errors with specific examples either real or fictitious.
