This online article is from the Museum's Seminars on Science, a series of distance-learning courses designed to help educators meet the new national science standards. "Profile: Albert Einstein," part of the Frontiers in Physical Science seminar, briefly covers Einstein's life and work including his Special Theory of Relativity and the paper that gave the world E=mcĺ_, his Nobel Prize in Physics, his influence yet exclusion from the Manhattan Project, and his promotion of peace and human rights.

In this exercise, students relate large-scale features on Earth's surface to lithospheric plates, the underlying asthenosphere, earthquakes, and volcanoes. After creating a cross section showing elevation using GeoMapApp, students add additional features by hand.

We publish novice-friendly, peer-reviewed tutorials that help humanists learn a wide range of digital tools, techniques, and workflows to facilitate research and teaching. We are committed to fostering a diverse and inclusive community of editors, writers, and readers.

The Programming Historian en español publica tutoriales revisados por pares dirigidos a humanistas que quieran aprender una amplia gama de herramientas digitales, técnicas computacionales y flujos de trabajo útiles para investigar y enseñar. Estamos comprometidos en la promoción de una comunidad diversa de editores, autores y lectores.

The Programming Historian en français publie des tutoriels évalués par des pairs destinés aux humanistes qui souhaitent apprendre un large éventail d'outils numériques, de techniques de calcul et de flux de travail utiles pour la recherche et l'enseignement. Nous nous engageons à promouvoir une communauté diversifiée d'éditeurs, d'auteurs et de lecteurs.

This is a culminating activity for the MMS Mission Educator's Instructional Guide. Learners should complete the four previous activities in the guide before moving to this activity. Learners will choose and complete three activities about the MMS mission. Activity formats can include creating videos, composing songs, developing written materials, constructing models, investigating current events, utilizing mathematics to explain concepts, and more. Depending on the project(s) chosen by a student, the project activity may require student access to internet accessible computers. This is lesson five as part of the MMS Mission Educator's Instructional Guide.

The soup-to-nuts exercises take students through the entire process of research with statistical data, from the very beginning when they first access the original data, through cleaning and processing the data to prepare them for analysis, to the very end when they generate the results that they present in a written report. Throughout each exercise, there will be an emphasis on adopting a transparent workflow and constructing replication documentation that ensures all the work done for the exercise can be independently reproduced.

Students have to determine the dimensions of a Quaternary rhyolite flow from a topographic map, employ a mineral thermometer to establish magma temperature, calculate density of the magma from its chemical composition, and use the Jeffreys equation relating flow velocity and viscosity.

In this activity students explore the evolution of proteins by comparing 2D and 3D alignments of orthologs and paralogs.

En esta infografía se describen las proteínas como biomoléculas, se indican las funciones que realizan y como están constituidas, haciendo incapíe en las estructuras por medio de imágenes

Simplified datasets for SPSS covering public opinion on social issues. The same questions were repeated over the course of several surveys from 1974 to 2004. Students can work with data both over time and for a single survey. Teaches students data analysis skills as well as about changes in beliefs over the past thirty years.

The programming language Python is widely used within many scientific domains nowadays and the language is readily accessible to scholars from the Humanities. Python is an excellent choice for dealing with (linguistic as well as literary) textual data, which is so typical of the Humanities. In this book you will be thoroughly introduced to the language and be taught to program basic algorithmic procedures. The book expects no prior experience with programming, although we hope to provide some interesting insights and skills for more advanced programmers as well. The book consists of 10 chapters. Chapter 5 and Chapter 6 are still in draft status and not ready for use.

Delve into a microscopic world working with models that show how electron waves can tunnel through certain types of barriers. Learn about the novel devices and apparatuses that have been invented using this concept. Discover how tunneling makes it possible for computers to run faster and for scientists to look more deeply into the microscopic world.

This fun Web site is part of OLogy, where kids can collect virtual trading cards and create projects with them. The site opens by telling kids that people have learned to change the food we eat. The first comic strip looks at a farmer who works to produce a larger, redder, tastier tomato. The second comic strip tells kids about genetic modification and imagines a scientist putting the flounder's "anti-freeze" gene inside the DNA of a tomato. Food for Thought presents kids with two scenarios about genetically modified food, asking them if they think they're good ideas.

This is a lesson about generating hypotheses and testable questions. Learners will use critical thinking and a collaborative approach to pose questions related to the study of Mars and evaluate the quality of their questions. They will explore remote-sensing data collected by a camera orbiting Mars - the Thermal Emission Imaging System (THEMIS) and develop a team science question. Students will practice critical thinking skills, use a collaborative approach to this first critical step of the scientific process. Exploring the images of the surface of Mars in Visible (VIS) images, students will come up with a topic of study, their team science question and hypotheses. The lesson models scientific inquiry using the 5E instructional model and includes teacher notes and vocabulary.
