Hotspot Animations

Today in our double period 9KMn made play-doh animations of Auckland's volcanic hotspot.

Auckland sits above a hotspot of magma, about 100km under our feet. 

A hotspot is an extremely hot area bordering the crust and the mantle, where temperatures are so high they melt the surrounding rock. There is a plume of hot rock rising out of the mantle as part of the mantles' constantly moving convection currents. It melts the rock and rises through the crust. It forces its way up to the surface and erupts to form a new volcano in Auckland.

How we made animations

Students used play-doh to create the crust, the hotspot, show rock melting, and showing the magma moving up through the crust to erupt at the surface. 

They set up the initial scence and took a photo using their Chromebooks. 

Then students moved the playdoh slightly, acting out what happens in the hotspot under Auckland. After each tiny movement another photo was taken.

One student got the job of adding each individual photo (one group took 51 photos!) to it's own Google Presentation slide. When the presentation is shared to the internet and plays automatically, it looks like a stop-motion animation! 

The final step was to add a few slides at the end of the animation for each student in the group to explain what their animation showed. The student who had added the photos to the presentation shared it to the other students in the group with full editing rights, and students were able to add their paragraph all at the same time (using their own words of course)

Students share their creations

Autymn, Nathan, Paris and Dante made an animation and Auymn posted about it on her blog here.

Please go and leave Autymn's group a comment about what you liked, learned or even what they could improve on next time we make stop-motion animations!
