Our volcano is similar to the Taal Volcano in the Philippines, it is a caldera type of volcano and is currently active as of now. The types of rocks that can be found around the volcano are Olivine Basalt (a type of mineral) and Andesite.

To make our volcano, we first decided which type of volcano we would make, a normal dome volcano or a volcano which shows the inside, similar to the diagram above. We first made a border to draw what it would look like inside the volcano, then we started creating the inside by using scrunched up newspaper. We then used some strips of newspaper and glue to smoothen the top. After leaving it to dry, we then painted it.
Elephant's Toothpaste
To replicate a volcano's reaction we did the elephant's toothpaste experiment. Using Hydrogen Peroxide, Potassium Permanganate Crystals and some detergent we made elephant's toothpaste.
We first tested it out to see if it would work, it worked, but we weren't so sure if the reaction was strong enough. So we tried soaking the crystals in warm water, next adding 1-2 drops of detergent, then immediately adding in the hydrogen peroxide. This made a reaction better than the previous one, so we used this method.

Hey Lyan!
ReplyDeleteThis is an epic post! I really like how you have laid this blog post out and the information you have shared! Great idea putting in the diagram explaining the different types of volcanoes, I liked looking at how they are all different. What was your favourite part of the project? Awesome blog post! :)
