First we are going to talk about real volcanoes and what makes them erupt and then we are going to talk about different ways to build a volcano and then we are going to talk about different ways to make your volcano erupt. So the materials that we are going to be using today to make our volcano, first of all we have Air-dry clay which we are going to use to actually construct volcano itself.
Why and how do volcanoes actually erupt? Volcanoes erupt when molten rock called magma rises to the surface. Magma is formed when the earth's mantle melts.
In this Education video tutorial you will learn how to do a cool volcano experiment at home. You will need a bottle of tonic water, mentos and some paper. Wrap the paper around the mentos to make a tube for releasing the mentos in to the bottle. Now pour about half a packet of mentos in to the paper tube and prevent them from falling off with your finger.
Mentos candies combined with diet cola will result in a powerful explosion. The soda can spray feet up in the air and will create a sticky mess. If you can find a red, carbonated soda this might work better to mimic the color of lava in a volcano eruption. As soon as the candies are dropped into the 2-liter soda bottle, it will begin to erupt. The eruption is due to the gelatin and gum arabic.
What chemicals make a volcano erupt? Since ketchup has vinegar (a dilute acetic acid), which reacts with baking soda (a base), this is an acid-base reaction experiment. When you mix baking soda with the dilute acetic acid in ketchup, carbon dioxide gas is produced. This is what will make the bubbles rise and fizz steadily to the top of the volcano. See Full Answer. 6. How do you make a volcano.
Making a volcano model is one of the most popular activities set in school and despite everyone being set the same task, the variety of models produced is a testament to the creativity of young learners today. We have collated a range of images of volcano models to inspire you. Plus you can find templates of volcano models that you can print off and make at home. Why not make a volcano model.
The data collected from eruption durations from the Diet Coke and Mentos eruptions can be applied to actual volcanoes. Like with the eruption heights, magma reacts to volatiles and heat like Diet Coke reacts to Mentos and heat, so some assumptions can be made about how a volcano will erupt based on how the Diet Coke erupts.
How does a volcano erupt facts? 11 Facts About Volcanoes. A volcano is a mountain that opens downward to a pool of molten rock below the surface of the earth. When pressure builds up, eruptions occur. In an eruption, gases and rock shoot up through the opening and spill over or fill the air with lava fragments. See Full Answer. Share. Upvote 9 Downvote 3.
