[Note: For embedded comments, checks for understanding (CFUs), and key additional information on transitions and key parts of the lesson not necessarily included in the below narrative, please go to the comments in the following document: Whole lesson w/comments. Additionally, if you would like all of the resources together in a PDF document, that can be accessed as a complete resource here: Whole lesson [PDF]. Finally, students may need their Earth Science Reference Tables [ESRT] for parts of the lesson (a document used widely in the New York State Earth Science Regents course) as well.]
Students come in silently and complete the (attached) Do Now. In this case, the Do Now is a review of some "hot standards" from the current unit - latitude/longitude and the differences between continental and oceanic crust. After time expires (anywhere from 2-4 minutes depending on the type of Do Now and number of questions), we collectively go over the responses (usually involving a series of cold calls and/or volunteers), before I call on a student and ask them to read the objective out loud to start the lesson.
As a general note, the Do Now serves a few purposes:
This lesson is actually relatively straightforward. The first page of the Directions & Map details the specific procedure necessary for mapping out the earthquakes and volcanoes. I gave out different colored pencils for them to use (pens are harder to erase with, and they will make mistakes, so use pencils if you can), and had them do all of the earthquakes before moving onto the volcanoes. After modeling 1-2 quick "points" with them, I allocate the rest of the time for independent work-time (I don't allow them to do this in groups, as I want them to get the uninterrupted chance to plot points on the latitude-longitude system independently).
[Note: For obvious reasons, it's important that students understand the latitude/longitude and coordinate grid system in order to plot the points effectively. Just for context, my lesson on this can be found here, which I taught earlier in the unit].
The Analysis & Lab Rubric section is completed immediately after they're finished with their point plotting. There are specific questions that ask students to infer the primary location of earthquakes and volcanoes based on the map points created. When they compare that to a similar image in the Earth Science Reference Tables [ESRT], they're able to see the similar pattern between plate boundaries and the location of major earthquakes and volcanoes (which is the entire point of the lesson!).
As you can see above, I try to make sure that students have the majority of class to perform the actual lab of plotting the latitude and longitude of the respective earthquakes and volcanoes. Since this is a laboratory-based lesson, there is no accompanying exit ticket for the lesson (Note: their scores are used by me to think about next steps from an instructional perspective, so the rubrics basically serve the same function in terms of student learning gaps – more information is on the reflection in this section). When time is up, I usually nominate a student volunteer to collect the colored pencils while I pass out the "Hot Spots" Homework and have students pack up.
As usual, I end the class at the objective, which is posted on the whiteboard, and ask students two questions:
Once I take 2-3 individual responses (sometimes I'll ask for a binary "thumbs up/thumbs down" or something similar), I have students leave once the bell rings.
