Function machine (grades 6-8)
Applying a machine metaphor for functions, this virtual manipulative allows the learner to examine the relationship between input (domain) and output (range). The learner inputs numbers from one to four and the virtual machine generates output information in a table. The learner is challenged to find the output for values five through seven and enter them in the table. Errors are noted automatically. Using a new function button, different types of functions are randomly offered for investigation

This informational piece, part of a series about the future of energy, introduces students to a three-stage process for viewing media. The three stages are preparing, viewing and listening, and reflecting. A student tip sheet explains each stage and enables students to work through the processes in a step-by-step manner while seeing how the information is tied together. Students prepare, examine, and critically summarize their new information. A graphic organizer provides students with an opport
Science Sampler : Weathering database technology
Collecting weather data is a traditional part of a meteorology unit at the middle level, but making connections between the data and weather conditions can be a challenge for students. One way to help students make these connections clearer is to enter the data into a database. This allows students to quickly compare different fields of data and recognize which readings are associated with certain types of weather.
Examine the sun at different wavelengths
This Earth science resource enables students to observe and compare the sun's appearance under different types of electromagnetic radiation. Students are instructed to move the cursor across the spectrum to see images of the sun under radio and microwaves; infrared, visible, and ultraviolet light; and gamma rays. Each image includes a label that indicates the portion of the electromagnetic spectrum, the wavelength in angstroms and meters, and the layer of the sun in view. Copyright 2005 Eisenhow

Quick take on action with fractions
Really understanding what fractions are, how they fit on the number line, and how to operate with them-add, subtract, multiply, divide-is central to learning decimals and percentages. According to the NCTM Principles and Standards, students in the middle grades should be expected to acquire a deeper understanding of fractions, decimals, and percents and an increased flexibility in using them to solve problems. Yet students may reach even the higher grades of middle school without a firm grasp of
LEARN was created to increase middle school science teacher knowledge of and interest in the atmospheric sciences. The original project began in 1991 with funding from the National Science Foundation (NSF). Much of the instructional and science content foundation for the LEARN workshops came from the teaching modules developed by LEARN teachers in collaboration with more than 60 National Center for Atmospheric Research (NCAR) scientists. The modules (Ozone in Our Atmosphere, Atmospheric Dynamics
