Aviation Memories
'Aviation Memories' is described as a 'virtual multi-channel video installation.' The work begins as an introduction to possible installations of video work, showing (with diagrams and animation) how monitors and related objects would be placed in a gallery setting. As the content of the video itself is described and presented, the work blurs the line between art object and planning document. Many of the images presented are derived from the illustrations of Jan Vredeman de Vries (1527-1604). Ar
RocketModeler
RocketModeler was developed at the NASA Glenn Research Center in an effort to foster hands-on, inquiry-based learning in science and math. RocketModeler is a simulator that models the design and flight of a model rocket. The program works in two modes: Design Mode or Flight Mode. In the Design Mode, you can change design variables including the size of the rocket body, the fins, and the nose cone. You can also select different materials for each component. You can select from a variety of standa
Chromatography theory and modes
This site is an introductory lecture in outline form about chromatography. It appears directed toward biochemical separations. The coverage is broad but not deep. Discussions of counter-current separations, gel permeation, and ion exchange are accompanied by some mention of partition, paper, and gas chromatography
Chromatography Theory
This site contains standard definitions related to chromatgraphy similar to treatments found in analytical textbooks. It introduces the beginning student to LC concepts relevant to biochemistry and includes a good example of choosing a mobile phase pH for a protein separation based on ion exchange.
The Periodic Table of Elements
This website developed by the Faculty of Chemical Technology in Croatia provides an interactive Periodic Table of Elements. Students and educators can find information dealing with each element's discovery history, thermal properties, ionization energy, minerals and use, isotopes, and reduction potentials. Besides the standard periodic table, this easily navigable website features an online remote control where visitors can quickly obtain information about the chemical either by name or symbol a

The NOVA documentary Search for a Safe Cigarette recounts the tobacco industry's decades-long attempt to engineer a safer cigarette. This companion Web site offers a number of interesting and informative features, as well as a lesson plan for grades 5-8 and 9-12. The interactive feature titled Anatomy of a Cigarette offers a fascinating tour of the conventional cigarette and two safer versions. The Web site also includes: a review of the safer cigarette's checkered pedigree; an animated introduc
The Golden Ratio
This Web site provides a basic introduction to one of the most amazing discoveries in mathematics: the Golden Ratio. Created by David L. Narain, this site offers a particularly engaging way to bring together math and the natural sciences in the classroom. Seven straightforward activities have students construct a golden rectangle and spiral, and also explore the Golden Ratio in nature and in other contexts. The site also includes a quiz; answers are not provided, though. The activities are desig

This virtual manipulative with an interactive three-circle Venn diagram can be used to model set operations for union, intersection, and subset. For each statement, the student uses an onscreen paint function to find and highlight the region that is the solution. The student can click a button to find out if his or her solution is correct. In addition to the manipulative, there are 13 progressively more difficult logic statements to challenge the student. Instructions for use and a link to the N
Number puzzles (grades 6-8)
This virtual manipulative challenges students to solve number puzzles using one- and two-digit addition. Each puzzle requires students to arrange a given set of numbers on either a triangular or square grid so that sides or the rows, columns, and diagonals add up to a given number. Students are able to check their answers on the web site, which includes instructions for using the applet, a description of related activities, and information for parents and teachers. There is also a link to the Na

The MathPARTNERS web site contains instructional materials that include background mathematics and pedagogical information arranged in four grade bands (K-2, 3-5, 6-8, and 8-9 algebra). Materials are designed for use by instructors or mentors in after-school programs and other informal education situations. In each grade band, there are four units focused on topics such as number and operation, geometry and measurement, statistics and probability, and patterns and functions. Units within grade b

This online activity opens with a map that illustrates three intersecting airport runways. The introduction calls students' attention to the numbers present at both ends. One runway number is missing, and students are challenged to determine what the number should be. This activity is one of 80 applied mathematics challenges featured on the FigureThis! web site. The importance of navigation to pilots, explorers, and scouts is noted. Students are encouraged to begin the activity by adding a zero

In this activity, students are asked to decide which would melt faster: a large block of ice or the same block cut into three cubes. The activity is one of 80 mathematical challenges featured on the FigureThis! web site. The animated introduction to this activity notes that surface area and volume are important to the work of architects, interior designers, and chemists. Students are encouraged to compare the surface area of the ice cubes to the larger block. The complete solution demonstrates h

This activity challenges students to interpret a bar graph to determine the average number of hours teenagers work per week. The activity, part of the Figure This! collection of 80 real world math challenges, explains how averages are used to describe data on academic performance, athletics, and wages. The Hint suggests that students assume that 100 students participated in the survey. Related questions ask students to calculate averages for additional data sets. The Did You Know feature offers
VCR : do you always get 6 hours of recording on a 6-hour tape?
This activity challenges students to use proportions to estimate how many 30-minute television shows can be recorded on a VCR tape using the SP (standard play) and the EP (extended play) modes. It is part of the Figure This! collection of 80 math challenges emphasizing math in the real world. The activity begins with the observation that fractions, ratios, and proportions are used in comparison shopping, making scale models, and describing population densities. The Hint suggests that students be
Gone fishing : my, my little fish, how you've grown!
Opening with a cartoon showing the weights of three combinations of fish, this activity challenges students to determine the weight of each fish. This activity is part of the Figure This! collection of challenges emphasizing real-world uses of mathematics. The introduction discusses algebraic reasoning and notes its importance to scientists, engineers, and psychologists. Students are encouraged to begin by adding the weights on all three scales. The answer page describes three strategies for sol
Auburn vs. Stetson (1953)
"Auburn opened its 1953 season with a 47-0 trouncing of Stetson in Montgomery. Auburn fans got their first look at "One Platoon Football" and saw the Plainsmen show a strong running attack and a stubborn defense. The Plainsmen scored in every period of the onslaught with seven men figuring in the scoring. Fob James scored twice on runs of 13 and 3 yards and Jim Pyburn scored twice on passes from Bobby Freeman. Other scorers were Charles Hataway, Bobby Freeman and Charlie Littles, who scored one

In this activity, students explore the nature and impact of friction. Students will observe, predict and record an object's motion over smooth, slippery and rough surfaces. These tasks will include an introduction to basic statics and dynamics in engineering through a discussion of forces and friction and a hands-on activity. Learners conduct 2 demonstrations using marbles and coins to learn about friction. Forces, simple vectors and free body diagrams which depict the forces can be discussed wi
Measuring (Const)
The purpose of this lesson is to introduce students to measuring with both the Standard Ruler and the Metric Ruler. Six attached worksheets will give students practice on measuring. A PowerPoint slide show is provided to introduce the pieces of a ruler. Working with their partners, students will complete worksheets representing equal portions of the inch (i.e. 1/4 and 3/4, or 1/8, 3/8, 5/8, and 7/8). This lesson provides background information for teachers and instructional procedures. Copyright
