Science Fair Project: How to Make a Volcano

Science is a subject that requires practicals and demonstrations, along with theory, to make the topic more understandable and easy to grasp. Science fair projects make studying science fun and interesting. A science fair project displays commonly asked queries on any science topics; be it math, physics, chemistry, biology, microbiology, earth science, technology, health and medicine.

There are certain tips for a successful science fair project such as - the project title should be an interesting one and it should not be very costly to make the necessary arrangements. The project should not be time-consuming, otherwise there are chances of the students getting bored and not completing the project. Let's take a look on how to make a volcano model.

Science Fair Project: How to Make a Volcano

The volcano science project is common and interesting among students. It helps the students in understanding how a volcano erupts and also about the triggering factors of a volcanic eruption. There are several ways of making a volcano model. However, the simplest one is by using baking soda and vinegar. Following is a step-by-step procedure for making a volcano model.

• The requirements for making a volcano are baking soda, vinegar, clay/play dough, food coloring either red or yellow (preferably red) and a plastic funnel or plastic water/soda bottle.
• First of all, take a strong base for placing the volcano model. You can make use of plywood or a hard cardboard and make sure that the base has boundaries, in order to prevent overflowing of the fluid after the volcanic eruption.
• Place the plastic funnel or bottle at the center of the base. You can secure this by using tape. The top center of the plastic funnel or bottle should be cut open, as it is the opening (crater) from which the lava will erupt.
• Once the plastic funnel or bottle is secured properly, mold the clay or play dough around it, to make the shape of a volcano. While putting the clay or dough, you should not cover the opening.
• For the eruption part, mix about 6-8 drops of detergent and a pinch of red food color. Add this mixture to a cup (about 500 ml) of warm water and stir well. The water quantity depends upon the size of the plastic funnel or bottle that you have used. Ensure that the solution fills about 2/3^rd of the plastic funnel or bottle.
• Now, add about two tablespoons of baking soda to the solution. Allow the mixture to settle for about 2-3 minutes. To make the volcano erupt, you can pour vinegar gently from the sides of the opening. The volcano will erupt in a few minutes due to the chemical reaction between baking soda and vinegar.

Well! This way, you can test volcano theories practically and understand the subject even better. In case, you find it hard to make a volcano model on your own, you can purchase volcano making kits that are available in the market and follow the procedure, as mentioned in the kit. To make it look more real, you can prepare the background with a scenery of forests and place pebbles and rocks on the volcano sides.
