This week we re-exploded our volcano and we pinned some things on a map. Re-exploding the volcanoes taught me that some volcano can get something to plug the top so that the magma can't get out. What this taught me is that when it does get plugged up the pressure inside of the volcano builds up and causes the volcano to blow the plug off. When we were pin pointing things on the map I realized how many volcanoes there are. Another thing that we did is we started to figure out what we are going to do for a project. The two choices for the project were earthquake country and land form detective but everyone in the class did land form detective. What we did for this is we started to research about the Siberian Traps but I did not find much.
S&EP:
This week we created a model of a lava dome. What we did is we used our existing volcano model and we placed a tube of powder into the hole of our volcano. After we placed the tube in we got some liquid and poured 1/3 of it in the hole then put a cork on top of the tube and waited. After a few seconds the cork flew off of the volcano and the liquid flew up a little. If the cork did not fly off, you had to shake it and it would fly off because all the pressure built up. We got to do this three times with the same tube and the liquid each time we only used a little so we kept using that. The closest thing that we did is we exploded our volcano . The similarities is that we used powder, our volcano models and liquid. The differences are that this time we used a clear liquid not one with color, that this time we only used 1/3 of the liquid and not the whole thing, and that we had to put a cork on the tube after we were done.
