CHEMystery: An Interactive Guide to Chemistry As of July 1, 2013 ThinkQuest has been discontinued. We would like to thank everyone for being a part of the ThinkQuest global community: Students - For your limitless creativity and innovation, which inspires us all. Teachers - For your passion in guiding students on their quest. Partners - For your unwavering support and evangelism. 50 Awesome Chemistry Videos For The Busy Science Teacher Though we don’t often recognize it, chemistry defines nearly every element of our everyday lives. From the reactions that fuel the sun to the biology of our bodies to the technology in our gadgets, chemistry is at the heart of everything we do and is the central science that unites biology, physics, geology, astronomy, medicine, and countless other fields. Yet chemistry doesn’t always get the credit and recognition it deserves for playing such an awesome role in, well, everything. If you’ve been slighting chemistry, there’s no better time to give the field the credit it deserves than National Chemistry Week. Founded in 1987, the week-long event has helped bring awareness to the role chemistry plays both in our lives today and in our future.

NASA Johnson The "Space to Ground" web series, available every Friday, features a short wrap-up of the week's activities aboard the International Space Station that showcases the diversity of activities taking place aboard the world's only orbiting laboratory. If you have questions or comments, use #spacetoground to interact with us. You might just see them in one of our episodes! Space to Ground: Coming and Going: 7/25/14 NASA's Space to Ground is your weekly update on what's happening aboard the International Space Station. Got a question or comment?

How many moons? We on Earth have just one moon, but some planets have dozens of them. Others don’t have any. Which planets have moons, and which don’t? Hot/Cold Pack Problem - Part 1 Page loaded on Thursday 12. Nov 2015 11:59:05 Name:__________________________ kinetics-equilibria Chemical equilibria . . . An introduction to the ideas surrounding chemical equilibria including the concept of a dynamic equilibrium, Le Chatelier's Principle, and a detailed look at the equilibrium aspects of the Haber Process, the Contact Process and the manufacture of ethanol from ethene. Plus an introductory look at equilibrium constants, Kc and Kp.

Science for Kids Water is an amazing substance! It can form into a beautiful snowflake in its solid state or evaporate into the air as a gas. Experiment with solids, liquids and gases to learn more about these states of matter. Physics Simulations at The Physics Classroom Welcome to Physics Interactives! This section of our website features a collection of HTML5 interactive pages that allow a user to explore a physics concept. Some Interactives are simulations that allow a user to manipulate an environment and observe the effect of changes in variables upon the simulation.

The Moon's phases in Oreos The Moon's phases in Oreos The Moon has "phases." That means it looks a little different to us each night during its one-month orbit of our planet. ReO3 - Rhenium trioxide: Interactive 3D Structure loadScript ../j2s/core/package.js loadScript ../j2s/core/corejmol.z.js

Virtual Labs The Virtual Lab is an online simulation of a chemistry lab. It is designed to help students link chemical computations with authentic laboratory chemistry. The lab allows students to select from hundreds of standard reagents (aqueous) and manipulate them in a manner resembling a real lab. More information and offline downloads. Please scroll below to find our collection of pre-written problems, they have been organized by concept and ranked by difficulty. Stoichiometry The Mole, Molarity, and Density Glucose Dilution Problem In this activity, students use the virtual lab to create a 0.025M glucose solution from a standard 1M glucose solution.

249 Bloom's Taxonomy Verbs For Critical Thinking Bloom’s Taxonomy’s verbs–also know as power verbs or thinking verbs–are extraordinarily powerful instructional planning tools. In fact, next to the concept of backwards-design and power standards, they are likely the most useful tool a teacher-as-learning-designer has access to. Why? They can be used for curriculum mapping, assessment design, lesson planning, personalizing and differentiating learning, and almost any other “thing” a teacher–or student–has to do. For example, if a standard asks students to infer and demonstrate an author’s position using evidence from the text, there’s a lot built into that kind of task.
