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

Watersheds
This web page focuses on watersheds, the topic of one of the books in the curriculum series that the larger web site accompanies. The page mentions why it can be beneficial for students to investigate local watersheds. The term watershed is defined, and examples of different sizes of watersheds are given. In addition, the page explains why local governments often manage watersheds. Links are provided to water quality experiments, to related online materials on other sites, and to information abo

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

Service-Based Engineering Design Projects
This unit describes a general approach to guiding students to complete service-based engineering design projects, with specific examples provided in detail as associated activities. With your class, brainstorm ideas for engineering designs that benefit your community or a specific person in your community. Then, guided by the steps of the engineering design process, have students research to understand background science and math, meet their client to understand the problem, and create, test and

Introduction to Circuits and Ohm's Law
Students will explore the basics of dc circuits analyzing the light from light bulbs when connected in series and parallel circuits. Ohm's Law and the equation for power dissipated by a circuit will be the primary equations used. Using these two equations circuits connected in series and parallel will be explored. Students will measure and see the effect of power dissipation from the light bulbs. Kirchhoff’s voltage law is used to show how two resistor elements add in series. While Kirchhoff

A New Angle on PV Efficiency
Students examine how the orientation of a photovoltaic (PV) panel relative to the sun affects the efficiency of the panel. Using sunshine (or a lamp) and a small PV panel connected to a digital multimeter, students vary the angle of the solar panel, record the resulting current output on a worksheet, and plot their experimental results.

The Challenge Question
This lesson introduces the “Walk the Line” Challenge question. Students are asked to journal responses to the question and brainstorm what information they will need to answer the question. The ideas are shared with the class (or in pairs and then to the class, if class size is large). Students then read an interview with an engineer to gain a professional perspective on linear data sets and best-fit lines. Students brainstorm any additional ideas and add them to the list they produced alrea

Bernoulli’s Principle
Bernoulli’s principle relates the pressure of a fluid to its elevation and its speed. Bernoulli’s equation can be used to approximate these parameters in water, air or any fluid that has very low viscosity. Students learn about the relationships between the components of the Bernoulli equation through real-life engineering examples and practice problems.

Through eight lessons, students are introduced to many facets of dams, including their basic components, the common types (all designed to resist strong forces), their primary benefits (electricity generation, water supply, flood control, irrigation, recreation), and their importance (historically, currently and globally). Through an introduction to kinetic and potential energy, students come to understand how dams generate electricity. They learn about the structure, function and purpose of loc

Heave Ho!
Students will discover the scientific basis for the use of inclined planes. They will explore, using a spring scale, a bag of rocks and an inclined plane, how dragging objects up a slope is easier than lifting them straight up into the air. Also, students are introduced to the scientific method and basic principles of experimentation. Finally, students design their own use for an inclined plane.
