Description of the activity/assignment
- In this brief pre-lecture quiz, students are asked to consider concepts that they have learned in previous lectures, and to answer the questions in a short period of time; hopefully without the aid of lecture notes. The quiz allows students to settle into the lecture, arrive late (many are coming from work), and refresh their geochemical knowledge from previous weeks.
- In this worksheet students balance chemical equations, work out numbers of moles and masses of compounds, and determine delta H and delta G for a common Earth-surface reaction. This is appropriate for first-year Geology/Earth Sciences students.
