All trials contained different amounts of baking soda and vinegar.

From your research you should discover why chemical reactions occur when certain substances are mixed. From this you will predict which mixed substances (yeast and hydrogen peroxide, baking soda and vinegar, or baking soda and lemon juice) will produce the most explosive eruption in your volcano.

But, all trials required me to put an amount of baking soda into the plaster volcano.

Volcanoes are extremely powerful, though often beautiful natural phenomenon. Power and beauty are two of the strongest natural basic needs or drives in a human soul. Therefore, when we simulate an explosion that replicates even a fraction of the depth of the power and beauty of volcanoes, we have done something great.

After the baking soda is placed into the volcano, I then added vinegar.

I did some research and thought that doing this project would bring back great memories and teach me something new!
Hypothesis
I feel that if I put the same amount of baking soda and vinegar in the volcano, the eruption will be the largest.

Conclusion: Analyze the data. Which of the three experiments provided the most realistic duplication of an actual volcano? (Was that what we were looking for?) We were actually looking for the most explosive substances. Let’s rephrase our conclusion. Which substances produced the most explosive reaction?

"Science Projects on Hypothesis for Volcanoes."

The first trial had 2 tablespoons of baking soda and 3 tablespoons of vinegar.

Research volcanoes and their eruptions. Try not to get distracted for too long with the literature on how people sacrificed other people to these purported volcano gods. (That is another scientific discipline, called anthropology.) Instead, learn about what powers their eruptions in scientific terms; what are acid/base reactions? What are --s? Build an answer to this question: how can a volcano be simulated? Does anything happen when acids and bases are mixed? Why? What is a decomposition reaction?

Week 3: Sample Week A Volcano Hypothesis and Analyses
Last week you did PBL Steps 1-6. This reading provides sample responses that someone could have made after reading the Volcano Scenario and applying the ESS and PBL approaches.

In Week 2 you were to read and analyze the Volcano Scenario (PBL Step 1), which contains an event and situation that tie together the ESS and the PBL Model approaches of the course. Step 2 of the PBL Model is to list hypothesis , ideas, or hunches. You were to focus your hypothesis, ideas, or hunches around the volcano event you read about in the scenario.

Here is an example hypothesis, idea, or hunch relating to the Volcano Scenario you worked with in Week 2:

Writing a Hypothesis for Your Science Fair Project

Finding an idea for your project can be the hardest part. Many students have sent us questions on topic ideas. Ideas for science fair projects can come from many sources, of course, but the following sites are great places to start to look for topic ideas!

In a volcano project, a hypothesis may try to explain why a ..

The steep terrain around the volcano would cause heavy runoff and less water getting into the ground water. As some stream valleys become filled with sediment, new stream values would form, further altering the landscape.

H > A > L
Water vapor emitted from the volcano can be precipitated in heavy, intense rain on the flanks of the volcano, which mixes with loose ash, creating massive mud flows. The mud flows mobilize any loose debris as well, forming lahars.

L > H > B
Tephra deposits can cover the ground around the volcano for hundreds of miles in diminishing depths further from the eruption. These deposits, and later erosion from their combination with water runoff, have the potential to scour fertile soil from farm and range lands, damaging their ability to support food and grazing crops.

E > H > L > B
As with Mt. St. Helen's, the heat of the eruption would melt vast quantities of ice. During the pre-eruption of a snowcapped mountain, a noticeable meltdown of the snow due to the increase in internal heat occurs. This meltdown will increase the water flow into small streams, creeks, and rivers. As the snow cover continues to melt, it eventually will pick up more dirt, mud, and debris from the runoff. The larger the amount of ice available to melt, the larger the potential mud flow that wipes out living things in its path.

E > L > A > H > B
Tephra, or volcanic ash, will be carried downwind and will fall to produce a deposit that covers a broad area, including rivers, streams, and oceans. The resulting silt will affect turbidity and oxygen-carbon dioxide cycles. This in turn will affect the biosphere and lithosphere as the silt filters through and is deposited on the ocean bottom.
