C-ROADS is a simplified version of a climate simulator. Its primary purpose is to help users understand the long-term climate effects (CO2 concentrations, global temperature, sea level rise) of various customized actions to reduce fossil fuel CO2 emissions, reduce deforestation, and grow more trees. Students can ask multiple, customized what-if questions and understand why the system reacts as it does.

This is an assessment activity for the The Cosmic Ray Telescope for the Effects of Radiation (CRaTER) educational kit. Learners will make a poster that explains possible origins of cosmic rays, how they affect people, and what protects us here on Earth. Alternately, they will make a poster describing CRaTER’s goal and how it works.

This lesson introduces the formal problem solving process that students will use over the course of the year, Define - Prepare - Try - Reflect. The lesson begins by asking students to brainstorm all the different types of problems that they encounter in everyday life. Students are then shown the four steps of the problem solving process and work together to relate these abstract steps to their actual experiences solving problems. First students relate these steps to the aluminum boats problem from the previous lesson, then a problem they are good at solving, then a problem they want to improve at solving. At the end of the lesson the class collects a list of generally useful strategies for each step of the process to put on posters that will be used throughout the unit and year.

This lesson has students recognize that computer science can help people in real life. First, students empathize with several fictional smartphone users in order to help them find the “right app” that addresses their needs. Then, students exercise empathy and creativity to sketch their own smartphone app that addresses the needs of one additional user.

Binary is extremely important in the world of computers. The majority of computers today store all sorts of information in binary form. This lesson helps demonstrate how it is possible to take something from real life and translate it into a series of ons and offs.

In this lesson, students will create an interactive Virtual Pet that looks and behaves how they wish. Students will use Sprite Lab's "Costumes" tool to customize their pet's appearance. They will then use events, behaviors, and other concepts they have learned to give their pet a life of its own!

This task was developed by high school and postsecondary mathematics and agriculture sciences educators, and validated by content experts in the Common Core State Standards in mathematics and the National Career Clusters Knowledge & Skills Statements. It was developed with the purpose of demonstrating how the Common Core and CTE Knowledge & Skills Statements can be integrated into classroom learning - and to provide classroom teachers with a truly authentic task for either mathematics or CTE courses.

Esse material didático é resultado das experiências do projeto de atuação na linha ambiente e sociedade do Programa de Pós-Graduação em Rede Nacional para o Ensino das Ciências Ambientais (PROFCIAMB), pela Universidade Federal do Amazonas (UFAM), tendo como base a dissertação “Abelhas nativas e educação ambiental: uma sequência didática interdisciplinar na formação do discente em agropecuária” que foi orientado pelo Prof. Dr. Neliton Marques da Silva.
Ele apresenta as sequências didáticas (SD’s) aplicadas junto a turma do 1º Ano do Curso Técnico de Nível Médio em Agropecuária na Forma Integrada, ofertados pelo IFAM campus Coari, com o objetivo de servir como um norteador para utilização das abelhas nativas sem ferrão como ferramenta educacional, especialmente na disciplina de ciências.

This exercise uses a number of Excel spreadsheets to calculate mineral formulae from compositional (microprobe) data. Numerous computational models are presented for most mineral groups (e.g. amphiboles, pyroxenes, micas), and students must critically evaluate which of these models is most applicable. Stoichiometry and charge balance are used to determine ferric/ferrous ratios--which is important for further applications such as geothermobarometry. Students are also asked directed questions about: compositional variation of the rock-forming mineral groups; representative complete, limited, and coupled solid solutions; site occupancy of major elements, as determined by the various computational models used; graphical representation of the calculated mineral formulae; and the composition and significance of certain varieties of these rock-forming minerals are addressed.

This is a spreadsheet that I use in petrology to walk students through calculating Rb-Sr isochrons and talking about isotope heterogeneity and sampling at various scales. The example exercise is the Tuolumne intrusive series. The file, available for download below, contains workbooks (see different tabs) with example isochrons and a spreadsheet of data for the homework problems.

This learning activity is designed to give nursing students confidence and skill with calculating safe dose medication ranges used in the clinical setting. It is designed to supplement textbook and classroom information.

This short exercise refreshes students memories about converting chemical analyses to mineral formulas, and mineral formulas to oxide and element weight percents.

Students convert between formulae and weight percents, showing all work.
The problem set handout has enough introductory material for students to be able to complete the problems without any instructor lecturing or textbook reading.

In this Biodiversity Counts activity, students learn how scientists calculate a biodiversity index using a page from the phone book as their data source. The printable five-page PDF handout includes a series of inquiry-based questions to get students thinking about what they already know about biodiversity and how living and non-living things are connected, step-by-step directions for calculating a biodiversity index, and a worksheet that includes brainstorming questions and areas for recording answers.

This is a very short exercise designed to get students to understand how the Gibbs energy equation is used to calculate the location of a reaction in P-T space. I use it in-class and have students work on it in groups.

Besides calculating the location of one reactions, students also have to think a bit about the significance of volume and entropy with regard to mineral stability.

This exercise is very straightforward EXCEPT that students get the units (bars, Kbar, cc, etc.) confused.

In this lab activity, students learn about the relationships between sea level and glaciers during glacial and interglacial periods. First the students need to calculate the maximum sea level rise assuming all water stored in glaciers and ice caps will melt. Then, they are asked to calculate the ice sheet distribution during the last glacial maxima based on the information that sea level dropped by 125 m.

Science students often have difficulty thinking about large spatial scales. The purpose of the exercise is to redo Eratosthenes' calculation of the radius of the Earth using data from to sites in ancient Egypt. The excercise teaches about the methodology of science - how Eratothenes figured it out - rather than worried about what the "right" answer is. It can also be used to discuss the role of models in geological thinking.
