One of the simplest working models of a volcano involves the use of baking soda and vinegar. The biggest benefit of the volcano is that simulates a volcanic eruption and it uses materials that aren't toxic.Continue Reading
To create this model, the first thing you have to do is make a cone for the volcano. Do this by mixing in six cups of flour, two cups of salt, four tablespoons of cooking oil, and two cups of water. This will create a mixture that is both smooth and firm. If it isn't easy to work with, then add more water.
Next, set a bottle into a ban and mold the dough around the bottle in the shape of a volcano. Make sure to leave the hole of the bottle open and to not drop in any of the dough. Now fill the bottle with warm water and red food coloring. Add six drops of detergent to the warm water, which will help trap the bubbles to produce better lava. Finally add two tablespoons of baking soda to the solution and slowly pour vinegar in the bottle. The addition of the vinegar will cause the eruption similar to that of a volcanoes.Learn more about Crafts for Kids
To build a composite volcano, get a cookie sheet, cardboard box, newspaper, brown paint, glue, tissue, baking soda, vinegar, dish washing liquid, a plastic bottle, modeling clay, red food coloring and glitter. Work on a large surface that is easy to clean.Full Answer >
To make a composite volcano, mix vinegar and baking soda together to create a mock eruption. The base in the form of baking soda neutralizes the acid in the vinegar and produces carbon dioxide gas, which causes the mixture to bubble and rise.Full Answer >
Make a volcano project by building a paper-mache volcano, measuring out the baking soda and adding vinegar. For this project, gather a 1-liter empty plastic bottle, a piece of cardboard, newspaper, flour, water, paint, dishwasher detergent, food coloring, baking soda and vinegar.Full Answer >
One idea for a fun middle school science project is investigating which ratio of vinegar to baking soda produces the best chemical volcano eruption. Other ideas include examining whether different brands of soda spew the same amount when shaken equally, whether different brands of potato chips are equally greasy and whether different types of bread grow different types of mold.Full Answer >
