Effectively demonstrates convection currents for middle school students.
Uses only very simple supplies!

This investigation is very effective as either a student investigation or a teacher demonstration of convection currents. The supplies are simple - hot and cold tap water, large beaker, small cup, rubber band, food coloring, and plastic wrap. The worksheet leads students (or the teacher performing the demonstration) step-by-step through a simple process, and then provides a section for observations and analysis questions. Year after year, this lab proves to be a "light bulb" moment when teaching middle school students about convection currents.
There are two very similar versions of this lab provided - one has more of a focus on convection in Earth's mantle and the other is strictly focused on convection currents. Take a look at both and use the one that fits your needs better.
