The baking soda and vinegar volcano is a favorite science experiment among elementary students. It is important to make your presentation stand out from the other students at the science fair with an exceptional presentation. Also be sure to follow the teacher's guidelines or science fair guidelines to ensure that your score is as high as possible.
Write an introduction. The introduction is your first impression. Be sure it is concise and accurately introduces exactly what you studied in the experiment. This is also an excellent place to include fun facts, background information or general volcano information. The reaction is due to the properties of bases and acids and would be important to include in your experiment. Identify the variable that you are testing, such as the ratio to vinegar and baking soda. Or maybe you would like to see what other base-acid combinations would produce similar eruptions.
Write a hypothesis. Remember a hypothesis is an educated guess or prediction. Explain what you believe will happen during the experiment based upon your previous knowledge or research. The hypothesis should be written in a declarative sentence.
List your materials. Provide a detailed list of all of the materials you used when you conducted the experiment. Be sure to also include how much of each material was used. Explain whether you made your own volcano or bought a kit.
Write your procedure. The procedure should be written step-by-step, in detail. If someone else could easily reproduce your experiment, you have probably written a fairly clear procedure. Be detailed, accurate and logical in your explanation. Procedures are usually written in a numerical list format.
Explain your results. Be sure your results reflect exactly what you were testing. You can provide observations or measurements. If applicable, you can create a chart or graph to describe any numerical data you may have taken. You may want to describe what the eruptions looked like, how long they lasted or how explosive the reactions were.
Write a conclusion. Basically, sum up what you learned during the experiment. Say whether or not your hypothesis was correct. Point out patterns in your data and explain if they were consistent with your previous knowledge of the subject. Also, do not forget to relate how that information can be used in the real world. This would also be a good spot to place recommendations if there are changes you would make to the experiment.
Items you will need
Avoid writing in the passive voice. Write in short, concise sentences. Be sure each idea is clearly presented.
This experiment should always be performed under adult supervision.
