Microbes : too smart for antibiotics?
This lesson packet builds on a peer-reviewed article about antibiotic resistance in microorganisms. The packet contains discussion questions about the article, instructions for an activity about hand washing that uses fake, fluorescent 'germs,' and two handouts of ideas for student activities. The first handout is appropriate for general biology students, and the second is designed for advanced, AP, or first-year undergraduate students. In many of the activities, students create a product, such

Examine the seasonal migration of snow cover
In this Earth science animation, middle and high school students observe the changes in snow cover on Mount Rainier over the course of one year. Accompanying text explains what a snow line is and instructs students to locate the snow line by examining the animation frame by frame. The animation is equipped with control buttons that allow students to play, pause, scroll, and step through the video. Students can click a button labeled 'Where on Earth?' to open a U.S. map showing the location of Mo

Quick take on the wide, wide world of geometry
As the social studies, art, and music classes in the middle school widen students horizons, some of your students may become fascinated with the art, costumes, and customs of other peoples in this and other times. The NCTM Principles and Standards calls for middle school students to be able to recognize and apply geometric ideas and relationships in areas outside the mathematics classroom, such as art, science, and everyday life.

Observe an animation showing evidence of the carbon cycle
In this visual resource about the carbon cycle, students are presented with an animation and accompanying text that focus on carbon and plants. The text addresses how plants fit into the larger carbon cycle, including how carbon enters and leaves the biosphere, and it explains what students are viewing in the animation. The animation shows false color images on a flat map of the world. When the viewer clicks on the image (or the play button), the animation plays, and color patterns reveal change

Science Sampler : The sweet Earth
A great number of geologic processes either take unimaginable lengths of time to complete, or happen in places that cannot be directly observed, such as under the Earth's crust. It is, therefore, necessary for an Earth science teacher to find a connection between students' experiences and the geologic process they are studying to help them better understand that which is often unobservable. One Earth science topic with a tendency to be beyond the reach of direct observation for students is rock

Scope on Safety : Waste not, want not
Planning chemical use and disposal is critical to a safe laboratory environment. It is irresponsible to simply go out and purchase laboratory chemicals without considering why they are needed and how they will be disposed of when they are no longer needed. An OSHA-based Chemical Hygiene Plan (CHP) should be adopted by the science department as the first step in this vital process. The procedures and operations for the purchase, use, storage, and recycling of hazardous chemicals are addressed in

Decarteret matches pole vault record at Florida State
The Northeastern women's track & field team recorded 15 top-10 marks, including another record-breaking performance by Jillena Decarteret, amidst stiff competition at this weekend's Florida State Relays in Tallahassee, Fla. Decarteret tied the school record in the pole vault with a winning performance of 4.06m (13'3.75), beating out 20 others for the title. The sophomore's vault matched Laura Chmielewski's mark set back almost seven years ago on May 8, 2004. Decarteret has continued to make upw

7.342 Systems and Synthetic Biology: How the Cell Solves Problems (MIT)
A millennial challenge in biology is to decipher how vast arrays of molecular interactions inside the cell work in concert to produce a cellular function. Systems biology, a new interdisciplinary field of science, brings together biologists and physicists to tackle this grand challenge through quantitative experiments and models. In this course, we will discuss the unifying principles that all organisms use to perform cellular functions. We will also discuss key challenges faced by a cell in bot
