The identification of a sea-floor microorganism that single-handedly conducts anaerobic oxidation of methane changes our picture of how the flux of this greenhouse gas from the ocean to the atmosphere is regulated.

Are you interested in using inquiry based learning in your classroom but are not sure of how to implement a new program? This post discusses the importance of planning and takes you through a step-by-step look at techniques you will use to effectively implement inquiry learning. Many additional resources are provided.
The “typical” high school science class consists of a large number of “cookbook” labs where the focus is on following the steps provided and collection of data. The majority of the lab is focused on filling in a certain number of “blanks” in order to complete the exercise. Not enough emphasis is put on the collection and interpretation of data. Application of science typically focuses on developing and testing a hypothesis, solving problems as part of this process, and using techniques to collect and interpret the meaning and significance of data. The protocols used are a tool to obtain the data and should not be the focus of the lab. The focus should be on the problem at hand (hypothesis testing), what the data means in terms of that problem and the conclusions that can be drawn from that data. This learning program is designed to help students gain more experience with how science really works. As part of this experiential learning process (i.e. hypothesis testing), students will be exposed to many powerful tools currently used to manipulate, clone, and analyze DNA.
Google’s Search Education feature gives educators free access to lesson plans and classroom activities intended to help students cultivate better online search skills.
The site is broken out into four categories:
Lesson Plans & Activities
A database of in-class lessons, from “Picking the Right Search Terms” to “Narrowing a Search to Get Better Results” to “Evaluating Credibility of Sources.” Each lesson is aligned to Common Core Standards and is available in three tiers: beginner, intermediate and advanced, depending on the age and skill level of the learner.
These free courses offer tips and tricks to finding online information quickly and efficiently. Students and teachers choose an instructor-led course (registration required) or a self-paced version to be completed at their leisure—plus, advanced search techniques for more skilled research and membership in an online community of search enthusiasts and researchers.
“A Google a Day” Challenges
Encourage students to use their newfound search skills to complete online skills challenges divided into four categories: Culture, Geography, History and Science. Each challenge includes a difficult topical question, hints to help students begin their search, the answer, and background for further classroom discussion on the topic.
An archived series of webinars focuses on helping teachers integrate search literacy into existing lesson plans. Learn how to use Google’s tools for education or get an expert tutorial in Google Maps before attempting to use it with students in class. The site also accepts suggestions from educators for future tutorials.
Educreations' Interactive Whiteboard is great for teachers, who can use it to create video tutorials or animated lesson plans. Scientists in a forgotten era always loved to draw out mathematical formula data or vectors on a blackboard. This is a high-tech example of the same thing. It’s not a bad idea for coaches or managers either.
