In this lesson, students will be making and studying the properties of their own mud using pH experiments.
They will be thinking about how pH affects microbes, and the ways that mudstones form, erode and break down.
They will look at water, earth and air as they explore the science of evolution and wonder about how to identify traces of early life on Mars.
