This activity teaches students about the value of planning, knowing, and explaining the limitations of a systems diagram. Students are taught to follow the following four steps when assessing the limitations of a systems diagram: identify the question, identify the scope, identify the missing sources, identify the level of detail. Students then assess the limitations of a systems diagram they previously created, and reflect on how assessing the limitations of a systems diagram also allows them to identify ways to improve their systems diagrams.

The goal of this exercise is to illustrate how each municipality needs to have a energy portfolio that is specific to their needs.
The students analyze a spreadsheet that links % of energy types to 6 output categories; cost, environmental impact, NIMBY, and three types of industrial emissions. As the students input % values for each energy type the overall value of each output category is calculated.
The challenge is for the students to come up with energy plans for multiple cities. Each of these cities would have different limits on either the maximum % of an energy type or one of the specific categories.
Example: Detroit, Michigan would use a low cap on the cost category so their energy plan would need to be very affordable. Seattle, Washington would only allow for 2-3% solar because climactic conditions don't favor solar energy.
For the last portion of the activity the students would come up with a plan for their own town and then be able to look up the current plan at https://www.epa.gov/egrid/power-profiler#/. They could then discuss how their plan and the currently implemented plan compare.

In this task students figure out how to draw the longest line on a map of the United States without hitting a border. They use color and line plots to keep track of their results.

The purpose of this task is for students to compare two options for a prize where the value of one is given $2 at a time, giving them an opportunity to "work with equal groups of objects to gain foundations for multiplication." This context also provides students with an introduction to the concept of delayed gratification, or resisting an immediate reward and waiting for a later reward, while working with money.

In this lab students will explore first hand what sorts of processes occur when scientists and engineers try to identify a landing site for a mission to Mars. This will mimic the process used to select the MER rover landing sites, and what will be used for future missions. First, students briefly become a planetary geologist, engineer or astrobiologist. Second, from the point of view the students feel is appropriate for their new position, and using the same constraints employed by the scientific teams preparing for forthcoming Mars missions, students will identify their top list of candidate landing sites and submit a short report describing them to me by the following class period. Third, in the following class period, all three groups of experts will work together to narrow down the site selection to a top candidate. Where would you send the next lander if the choice was up to you? Each student group, constituted randomly, is provided with the appropriate role-playing sheet from the lab assignment.

Open courseware for Macroevolution, focusing on research methods and software packages, such as R.
Course description Evolutionary thinking provides the underpinnings of modern biology. In recent decades, the field of macroevolution (evolution above the species level) has matured into a rich discipline with a well-developed mathematical theory for testing hypotheses of species diversification, for understanding trait evolution, and evaluating patterns of covariation across the tree of life. This course will provide a synthetic view of biology and how life on earth has changed over time.
Course Outcomes Upon completion of the course, students will: Understand patterns of diversity in the fossil record, and changes in that diversity over time Understand macroevolutionary patterns and processes, and the difference between gradualism, stasis, and punctuated equilibrium Become familiar with ‘tree thinking’, and understand the principles of using a phylogenetic perspective to address evolutionary questions in biology Gain experience in applying cutting-edge phylogenetic methods for testing hypotheses in macroevolution

This exercise is centered around a suite of rocks from the Sierra Nevada batholith. The activities are designed to give petrology students a capstone experience for the igneous portion of the upper-level Petrology course. Students are given thin sections with hand samples, a map and a table of geochemical analyses (in Excel format) and asked to record hand-sample and thin section observations with the idea that these will be used to understand processes that were active during batholith generation. By the time they encounter this lab, the students have spent at least 7 lab periods looking at a variety of igneous rocks and their textures. Because students are given geochemical analyses, they are also expected to experiment with the use of graphs (e.g., Harker and spider diagrams) to better understand tables of geochemical analyses. The students use observations about rocks and geochemistry to build a coherent story around these rocks; the final product is a short paper in which they use petrographic observations and geochemical diagrams to back up their interpretations.

Dissolved ions are present in all freshwater systems, but humans can change the chemical composition of freshwater in several ways. In this activity, students will examine the concentration of major ions in freshwater systems over time and reason about potential drivers of these changes.

Many people live in regions prone to earthquakes, tsunamis and volcanic eruptions, but the hazards and risks inherent in our communities may be very different. Making connections with learners from another location is a great way to share knowledge and practice science communication skills. Video conferencing applications like Zoom and Skype make it possible to connect with learners anywhere in the world. This activity provides a simple protocol, and a form for submitting a request to connect with a classroom teacher in Anchorage, Alaska.

The goal of this maker challenge is to demystify sensors, in particular the ambient light sensor, and to map its readings visually. In today’s world, we make sense of the environment around us by filling it with sensors, and we use output devices to display real-time data in a meaningful way. Take any smartphone as an example. Aside from the embedded camera and microphone, a number of other sensors collect a wide range of data. Depending upon the model, these sensors may collect data on proximity, motion, ambient light, moisture, compass, and touch. Some of these data are directly visualized through an app, while many operate internally and without a user interface, just below the surface of the screen. In order to become more familiar with the technology that we use (and often take for granted) on a daily basis, your challenge is to assemble a light sensor circuit, observe its readings using the Arduino Serial Monitor, and then create your own unique visualization by interfacing with the Processing software. Students learn how to use calibration and smoothing to capture a better picture of the data. Afterwards, they share their visualizations with the entire class. The time required for this challenge depends on students’ prior knowledge of Arduino and Processing software. Background resources for beginners help students get up to speed on microcontroller hardware and offer additional challenges for intermediate and advanced users.
