Inside Earth Lab
Convection Cells Lab
In this lab, students witness the rise and fall of fluids based on the level of heat energy & density. As things warm up near the source, it makes the molecules in the fluid vibrate more and faster - this means that they need more space to move. When this happens, the fluid becomes less dense than the surrounding material and it begins to rise. Once it reaches the top, the fluids cool down and become slightly more dense than the surrounding materials and the fluid begins to drop.
Lab & Demo Ideas:
- How to find the depth
- Using P wave analysis to create a Stress Tensor ball
- Soil Wave Analysis - dragging a cup full of water on a brick
- Liquefaction - sand and objects in a cup - shaken
- Stress/Tensor Coulomb
- Block Modulus
- Stress v. Strain on rock materials
- Speed of sound through compressed materials
