Teacher's Toolkit : Reforming cookbook labs
The majority of ancillary materials provided with any textbook includes a large quantity of labs that have step-by-step instructions. Although it is important in science for students to learn how to follow directions, offering only cookbook labs limits students' access to exploration. Presented in this article are 11 different ways of altering cookbook labs so that students understand the intention of the procedure. The altered labs do not fully achieve the status of inquiry-lab, but they are a

Science Sampler : Fossil detectives
Middle school students are transformed into Fossil detectives as they examine the fossil record and use evidence about paleo-environments to develop an understanding of structure and function in living systems and changes over time in Earths history. In this enrichment activity, students work in teams to research an assigned geologic time period. They determine available habitats, food sources and types (animal, plant; woody, herbaceous, etc.), cover sources, methods of getting food, defense, an

Angles
This Java applet enables students to investigate acute, obtuse, and right angles. The student decides to work with one or two transversals and a pair of parallel lines. Angle measure is given for one angle. The student answers a short series of questions about the size of other angles, identifying relationships such as vertical and adjacent angles and alternate interior and alternate exterior angles. In addition to automatically checking the student's answers, the applet can keep score of correc

Cold Clouds and Water in Space
This article from Astrobiology Magazine reports on the discovery of water in cold regions of space. Using data from the European Space Agencys Infrared Space Observatory, astronomers have determined that water is abundant in these cold, or quiescent regions of space where there are no stars, and that the majority of it occurs as ice with a small amount of water vapor. It is thought that these cold regions of space might be the future birthplaces of low-mass stars like our own sun. Links to other

The future of energy, efficiency
Energy-efficient appliances and vehicles can greatly reduce the amount of energy Americans use. This informational piece, part of a series about the future of energy, introduces students to the consequences of using energy more efficiently. An example about baking a pie provides students with a practical definition of efficiency. A discussion of energy-efficient appliances and processes follows as students read about the Energy Star label. The overall efficiency of a power plant is described, sh

Nanomedicine : Problem Solving to Treat Cancer
Students rarely have the opportunity to delve into the unknown and brainstorm solutions to cutting-edge, unsolved science problems that affect thousands of people. To counter this trend, the following activity was developed to expose students to issues and problems surrounding cancer treatment using an inquiry-based approach. Through this activity, students step into the role of ?real? scientists and brainstorm possible treatment options by working collaboratively, utilizing problem solving stra

Student time on task is the most influential factor in student achievement. To maximize time on task, teachers need to make decisions about the systems they install in their classroom well before any students enter the room. Beginning the school year by explicitly teaching process skills and having classroom operating systems that reinforce process skills are two strategies that lay the foundation for logical thinking throughout the year, which are discussed in this article.

Stats for Schools
Stats4schools, developed by the United Kingdom's Office of National Statistics, is about helping teachers and pupils to get more from statistics. The project has posted here datasets collected by the Office for National Statistics as part of the Omnibus survey and made them available for students to download free of charge. Teachers will also find lesson plans, worksheets and datasets that can be used in their classrooms. The lesson ideas are organized by topics and involve using statistics to a

New York Times Daily Lesson Plan: Mathematics
These lesson ideas from the New York Times offer suggestions for ways to draw on real world issues and statistics to develop lessons in mathematics. For example, in one lesson students convert statistics about gun injuries into visual presentations, then use these as the basis for a poster campaign to teach children about the dangers of guns in home while another lesson idea involves designing brochures that are intended to explain specific mathematical concepts to a popular audience. Each lesso

What's That Stuff?
What's That Stuff? Well, the Web site provided by Chemical and Engineering News answers this question on many of those everyday items that are just a bit curious. For example, Silly Putty is a dilatant compound, which means it has an inverse thixotropy--that is, as a viscous suspension or gel, it becomes solid under the influence of pressure. The site explains the history and characteristics of this and over twenty other substances such as sunscreen, cheese whiz, baseballs, fluoride, new car sme

Activity : Fusion Reactions
This activity gives students an opportunity to learn about the elements created in the cores of high-mass stars by fusion reactions. They will discover that all stars start by burning hydrogen and end up creating many heavier elements inside their cores, elements that will be released into space when it dies in a supernova explosion. Students associate a layer with an element that is being produced by the high-mass star. This will illustrate that as the temperature of the star increases with dep

2.4.1 Multimode distortion
Optical-fibre communications became commercially viable in the 1970s and innovation continues today. This unit will illustrate how very high data rates can be transmitted over long distances through optical fibres. You will learn how these fibres are linked, examine the technology used and assess the future direction of this continually developing area of communication.
