Today we did a demonstration about covection currents, using bunsen burners, beakers, styrofoam and food colloring. We used the bunsen burners to heat up the water in the beakers, then we put in the food colloring to help show the movemnet of the bubbles. The styrofoam is an example of the magma that moves during the process of convection currents.
I observed that the styrofoam that was put into the water moved with the currents. They moved around like the rocks would have. I also realized that the currents have to move fast for them to move the rocks around.
We did this observation to help learn about the process of convection currents. Also to learn about how convection currents move the plates.
