Homepage for a hypertext about the different families of musical instruments. From this page, users can retrieve information on a the acoustics of a variety of specific instruments: stringed instruments, woodwind instruments, brass...

Medieval and Renaissance-era scientific instruments are catalogued and displayed. Find references to the makers of the instruments and the ways the tools were once used.

A great resource for teachers, students, and performers of string instruments. Very indepth "how-to" descriptions, care information, procedural movies, and more.

Learn all about the basic meteorological instruments.

Based off of the hit television show NUMB3RS, this lesson introduces students to one of the prominent algorithms in graph theory used to find shortest paths -- the Djikstra Algorithm. The lesson includes four graphs of increasing...

Solve equations and find zeroes of functions using the TI-83 in this lesson. Keystroke instructions and calculator screenprints are included to help students with the activity.

Based off of the hit television show NUMB3RS, this activity shows students how money invested at different interest rates grow differently. The lesson focuses on aspects of interest such as compounding, length of time between...

Challenge your advanced algebra or pre-calculus students to finding the equation of an angle bisector given two intersecting lines. Students can do this in several ways; the lesson plan here walks through two of them in this interesting...

In this activity, students learn to identify geometric series. They determine if a sequence converges and also learn to calculate the sum of numbers in a geometric series.

Students explore and use the concept of ratio in a real-world situation. They will make judgments regarding accuracy and precision of measurement.

The interactive Cabri Jr. geometry application makes it easy to measure the area of triangles and quadrilaterals. In this activity, students will explore some interesting area relationships in quadrilaterals.

In this activity, students will draw and color scaled drawings of traditional quilt block designs. They then find the appropriate fraction, decimal, and percent of the overall design for each color.

This TI InterActive! activity is an algebra test which examines the student's understanding of Rational Functions.

This tutorial shows you how to enter a set of data and find the line of best fit.

Students examine the USA TODAY Snapshot "More of U.S.", construct a graph from the data, produce a mathematical model (linear) for the data, determine the rate of change for the data, and make predictions about future population levels.

In this activity, students will find and compare function rules for a given pattern. They also evaluate variable expressions.

This activity will use the capabilities of their graphing calculator to illustrate the symbolic derivative product rule.

Students study quadratic relationships and explore the process of graphing quadratic inequalities and systems of quadratic inequalities. They will solve these inequalities algebraically and graph them on a coordinate plane.

The following LearningCheck file was created for educators in Texas to have supplemental assessments in preparation for the 9th grade TAKS exam. The assessment involves topics covered in Objectives 1-4 in the 9th grade objectives.

Students will examine the current and predicted population data from the countries included in the USA TODAY Snapshot "Growing bigger by the decade".

In this activity, students will perform a series of experiments with inclined planes. They will learn that as the angle of inclination of the inclined plane approaches 90 degrees, the value of the acceleration of the cart traveling down...

The student is given actual data and asked to find a line of best fit and to give "real world" interpretations of the slope and y-intercept. A great introduction to the 83/84 and its features.

In this activity, Students can use colorimetry to determine the concentration of a colored species in a solution and use a linear relationship to model Beer's law. They use Beer's law to determine the concentration of...

This activity center is used to illustrate the difference between the slant height and the actual perpendicular height (of the given square pyramid) by the use of the distance formula.
