Not really, the better expiriment would be if you used both sides of t he penny and compare all of your trials.
Draw a valid conclusion for that experiment.

A valid one. An experiment cannot conclusively prove anything if more than one independent variable is altered at a time. That being said, many dependent variables could show change and the experiment would still be valid, as long as only one independent variable was altered at a time. An experiment that changes only one variable at a time is called a controlled experiment.
Yes, an experiment can be reliable but not valid. Reliability refers to the consistency of the results when the experiment is repeated under the same conditions, while validity assesses whether the experiment measures what it is intended to measure. For instance, a poorly designed experiment may produce consistent results (reliable) but may not accurately reflect the true relationship between the variables being studied (not valid). This highlights the importance of both concepts in research design.
To be considered valid, the results of a scientific experiment must be reproducible, meaning that other researchers should be able to replicate the experiment and obtain similar results. Additionally, the experiment must be based on a well-defined hypothesis and use appropriate methodologies to minimize bias and errors. Valid results should also be analyzed statistically to determine their significance and reliability.

A control is needed in a valid experiment because without controls then more then one variable is being tested. This can mess up the results.

A valid experiment is characterized by a clear hypothesis, a control group for comparison, random assignment of participants, and the ability to replicate the results. It should also have ethical considerations and controls in place to minimize bias and confounding variables.

Scientists use the data from an experiment to evaluate the hypothesis and draw a valid conclusion.
In a valid experiment all the variables are kept the same apart from those being investigated.
