The Elements Revealed: An Interactive Periodic Table In the October 2011 issue of Scientific American, we celebrate the International Year of Chemistry. Learn more about its impact on our daily lives in our Special Report. UPDATED: 06/18/2013 In honor of the 2013 Lindau meeting, which focuses on chemistry, we have updated our interactive periodic table with links to Nature Chemistry's In Your Element essay series.

Interactive by Krista Fuentes Davide Castelvecchi Davide Castelvecchi is a freelance science writer based in Rome and a contributing editor for Scientific American magazine.

The Path of Blood through the Human Body When a heart contracts and forces blood into the blood vessels, there is a certain path that the blood follows through the body. The blood moves through pulmonary circulation and then continues on through systemic circulation. Pulmonary and systemic are the two circuits in the two-circuit system of higher animals with closed circulatory systems. Humans and other mammals have two-circuit circulatory systems: one circuit is for pulmonary circulation (circulation to the lungs; pulmo = lungs), and the other circuit is for systemic circulation (the rest of the body). The intertwined circulatory system pathways: Pulmonary circulation and systemic circulation work together. Pulmonary circulation Blood that is lacking oxygen is said to be deoxygenated. Superior means higher, and inferior means lower, so the superior vena cava is at the top of the right atrium, and the inferior vena cava enters the bottom of the right atrium. Systemic circulation The pulmonary veins enter the left atrium.

WebElements Periodic Table Il grafene, nuovo materiale delle meraviglie Impostazione della lezione La lezione può prendere l’avvio da una discussione sul significato di allotropia, le caratteristiche dello stato solido e dell’importanza del carbonio in natura e nelle attività umane. Le proprietà del nuovo materiale delle meraviglie: “Il grafene” A cosa serve il Grafene? Il carbonio è certamente il più versatile tra gli elementi chimici, in quanto è in grado di formare una grande varietà di molecole, i cosiddetti composti organici, in numero di gran lunga superiore a quello tutti i composti formati dagli altri elementi. Il carbonio è presente in natura in forme cristalline diverse dette allotropiche, dal greco αλλοσ, altro, e τροποσ, modo. Nel diamante gli atomi di carbonio sono legati l’uno all’altro mediante legami covalenti che formano una struttura tetraedrica. Si pensava, fino a pochi anni fa, che non fosse possibile isolare un singolo piano di grafite, in una forma tale da poter effettuare misure di tipo elettrico. Applicazioni del grafene

Explore Shale geology, water, gas, oil The Nine Planets Solar System Tour Science Interactive Student Notebook I wanted to post some pictures that could help describe my last post. With the wedding coming up and me living over an hour away from school, my visits to school have been minimal to say the least. I'll get into school at the end of August and I'll post pictures of the classroom then. I hope these help you out :) Composition Notebooks These are the BEST. This is just some scrapbook paper that I found in Michael's that was on clearance AND another 15% off because I had my teacher ID. Can't Live Without Supplies - most of them :) I've said it before, I'll say it again, I LOVE COLOR! Glue sticks and tape (missing) are a must, must, must for this to be successful. We mostly use tape in my class. Let's start with the pencils. Highlighters are fun and colorful and bright. I love colored paper. Just for Fun! Pinterest (Follow Me!) ISN Bins Ok, so before you take a look at the pictures below, I just want you to know this is the bin that I use in my class.

VESTA 1. Introduction VESTA is a 3D visualization program for structural models, volumetric data such as electron/nuclear densities, and crystal morphologies. Some of the novel features of VESTA are listed below. Deal with multiple structural models, volumetric data, and crystal morphologies in the same window. VESTA is a successor to two 3D visualization programs, VICS and VEND, in the VENUS (Visualization of Electron/NUclear and Structures) software package. VESTA runs on Windows, Mac OS X, and Linux. 2. Visualization of crystal morphologies Superimposition of multiple structural models, volumetric data, and crystal faces on the same Graphic Area Visualization of isosurfaces with multiple levels An extended bond-search algorithm to allow more sophisticated search in complex molecules, cage-like structures, etc. 3. 4. VESTA is originated from two GLUT- and GLUI-based applications, VICS and VEND, developed by R. Oct. 4 2016 ver. 3.3.9 Refined automatic bond search behavior further.

Molecular Workbench - Database Molecular Workbench offers interactive, visual simulations and activities that have been widely used in science teaching for students of all ages. Our database is designed to provide teachers and students with easy access to our model-based activities. The activities are derived largely, but not entirely, from projects of the Concord Consortium sponsored by the National Science Foundation (NSF). The models are primarily of interactions of atoms and molecules, or rule-based genetics. All activities are accompanied by: colored icons to indicate degree of support technological requirements links to concepts and disciplines links to standards links to some textbooks Activities can be accessed by typing an activity number in the field Jump to Activity at top right. Note: This database is in development.
