CRYSTAL GARDEN FINALE

Guiding Question for this project was: How do crystals grow?
Crystals grow from when solids in a water solution stay put and the water evaporates, leaving crystals behind.


Over the last two weeks, the crystals are still minute. On day one, I covered the trees with magnesium sulfate solution. I also, put several drops on the ground. I then used borax and put some in the bushes. The next day some crystals appeared on the "grass". However the cardboard still showed so i gave a more generous amount to all of it. Several days later, I put some more magnesium sulfate on the trees and the house and the rock.2 days later, I put some foil where the river should be and poured in sugar. My river filled with glucose sugar has dried up. It was really full and what do I get? A tiny crystal trimming. And my trees still have no crystals despite how much stuff i put on. The stuff that has grown is the grass and the red house and that uses magnesium sulfate. Talk about really slow growth The levels of crystals weren't high. In fact it was rather low. It was fun making the crystal garden, but i'm not that impressed with the out come.

Mapping volcanoes and earthquakes lab

In this lab, I noticed several volcanoes near the faults and subduction zones such as the ring of fire and the fault area of the Euraisian plate. Also, most of the volcanoes and earthquakes are in lines-squiggley and not straight-and make similar shapes to the ones of the tectonic plates
