What if my hypothesis is wrong?
When a hypothesis fails, the first thing you should do is examine the data closely. Then use your research and data to determine a possible reason why the hypothesis was incorrect. Once you come up with a reason your hypothesis may have failed, you can start thinking of ways to check your assumption.
What is hot ice?
Sodium acetate or hot ice is an amazing chemical you can prepare yourself from baking soda and vinegar. You can cool a solution of sodium acetate below its melting point and then cause the liquid to crystallize. The crystallization is an exothermic process, so the resulting ice is hot.

Mistake is just another word for a failed experiment. The purpose of experiments is to confirm or deny a hypothesis, or in other words, to learn something. Saying that we made a lot of mistakes is also saying that we ran many experiments.
What might cause a scientific experiment to return incorrect results?
Common sources of error include instrumental, environmental, procedural, and human. All of these errors can be either random or systematic depending on how they affect the results. Instrumental error happens when the instruments being used are inaccurate, such as a balance that does not work (SF Fig.
