Water and Mud: Linking hydrogeology and landscape change part of Cutting Edge:Hydrogeology:Activities
Hydrogeology textbooks usually do a poor job in linking groundwater to Earth's surface processes, yet the two are closely linked. It is important for the hydrogeology student to understand that surface and subsurface water play a role in shaping the land where they live. This session will demonstrate the importance of hydrogeology on the rates and styles of landscape change through simple numerical models and by using a case-study of a local landslide.
'Radioactive' decay of chewing gum part of Cutting Edge:Introductory Courses:Activities
This activity allows students to see (and feel) the decay of chewing gum as it relates to ½ lives. One or two students chew gum during class and each minute they weigh the gum. At the end of the experiment students calculate the half-live of chewing gum.
