This is one of my favorite activities from our minerals and mining unit. It takes about 1 whole class period to explain the activity, collect data, eat the cookie (& crumbs), and clean up. We discuss our results the next class and determine who made the most profit.
When determining the value of the chocolate ore, I have the students place their chocolate pieces close together in one area of the map. When they are done, I go around and circle the area of chocolate and give their chocolate a rating. They count the number of boxes their chocolate covers and enter it into their spreadsheet.
If there are crumbs attached to the chocolate, I call that ‘slag’ and it lowers the value of the chocolate ore. This leads to a great discussion afterwards when we compare the profits and talk about land use. Is it better to get out as much chocolate as you can, even if you get a lot of slag, or is it better to remove just the chocolate even though you will have less in the end? How is this similar to coal mining? Diamond mining?
to edit this spreadsheet, make a copy for each map, then share editing rights with each group of students who will be working on that map
if you don’t use Google Drive, you can download the Google Sheet as an Excel spreadsheet
ex: Map A data is shared with 4 students from period 1, 4 students from period 2, 4 students from period 3, 4 students from period 4, and 4 students from period 5. When done, they will have 200EQs plotted and color coded on the table top map.
Colored pencils or markers per map
1 Table sized map per lab group (3-6 students) – printed and assembled
The map will remain on the table, as the next class comes in, they will add the data for their assigned region(s) to the same map as the class before them
We are heading into Peak Hurricane Season, with forecasts predicting 12-17 named storms. Using the resources below, students can track Tropical Storms and Hurricanes, as well as learn about how hurricanes form, the parts of a hurricane, the difference between a tropical storm and a hurricane, and the intensities of hurricanes with this mini-unit from my Adopt-a-City Weather Unit (link).
