A conclusion has four parts:
1. Reflects back on the original hypothesis and states whether it was supported by the results of the investigation or not.
2. Answers the original question that started the investigation and includes the results that were used as the basis for that answer.
3. States any inferences that can be made from the results of the experiment.
4. Mentions any additional questions that could be investigated or information that could be researched in the future.

Question: Here is the details to help you out
What effect does adding soap to water have on the number of drops that can be placed on a penny?
Trial 1: Tap Water 42 and soapy Water 30
Trial 2: Tap Water 43 and soapy Water 29
Trial 3: Tap Water 42 and soapy Water 31
Average mean: Tap Water 42.333 and soapy
Water 30
The data collected from the experiment show that when soap is added to water, the number of drops that can be placed on a penny decreases compared to tap water alone. The average mean number of drops for tap water was 42.333, while the average mean for soapy water was only 30. This indicates that the addition of soap had a significant impact on the surface tension of the water, making it more difficult for water drops to stay on the penny. Each trial consistently showed fewer drops for soapy water compared to tap water, suggesting a clear trend in the data.
The independent variable in my science project is the types of water. Tap vs soap.
The dependent variable in my project is the number of water drops on the surface of the penny.
hypothesis: If a penny is covered with soap, then it will not hold as many water drops because the soap does not allow for adequate surface tension to occur.
Prediction: Soap reduces the surface tension of water, allowing the penny to hold more drops with soap compared to without soap. The relationship between the water molecules is broken by the soap molecules, allowing the drops to more easily spread and cover more of the surface of the penny.
