Spring SAVY 2018, Day 1- Earth Explorers (1st/2nd)

Posted by on Monday, January 29, 2018 in Grade 1, Grade 2, SAVY.

We started off our Earth Explorers course with a bang! Beginning the fundamental force of gravity we worked our way through basic concepts that are central to Earth’s structure including, matter, mass, and density. A number of exciting experiments involving liquids of different density illustrated how different layers can float on top of one another! This is just like how the layers of the earth are differentiated by density. In particular, Earth’s crust floats on top of the mantle, which is a sort of silly-puddy like mass that has currents that push and pull the continents that ride along on top. We ended class with an experiment that showed convection currents developing in a plastic basin of water with ink blots that highlight the currents. An example of this video is attached here. Looking forward to next week when we begin to look at how rocks are made!
