After conducting the associated activity, students are introduced to the material behavior of elastic solids. Engineering stress and strain are defined and their importance in designing devices and systems is explained. How engineers...

Students learn about the fundamental strength of different shapes, illustrating why structural engineers continue to use the triangle as the structural shape of choice. Examples from everyday life are introduced to show how this shape is...

In this lesson and its associated activity, students conduct a simple test to determine how many drops of each of three liquids can be placed on a penny before spilling over. The three liquids are water, rubbing alcohol, and vegetable...

After students conduct the two associated activities, Density Column Lab - Parts 1 and 2, present this lesson to provide them with an understanding of why the density column's oil, water and syrup layers do not mix and how the concepts...

Students apply everything they have learned over the course of the associated lessons about waves, light properties, the electromagnetic spectrum, and the structure of the eye, by designing devices that can aid color blind people in...

This curricular unit contains two lessons that let students actually do the work of scientists as they design their own experiments to answer questions they generate. In the first lesson and its associated activity, students conduct a...

Students learn the basic properties of periodic and harmonic motion, and how the rearrangement of the simple pendulum equation can be used to solve for gravitational acceleration, pendulum length, and gravity. At lesson end, students are...

For this activity, students explore nine scatter plots to develop their understanding of how two quantitative variables are related. Through an exploration of the properties of this association, they come to understand the standard...

Get the definition and properties of a polygon. Then explore such topics as: 1) types of polygon 2) area 3) Perimeter 4) angles associated with polygons and 5) names of polygons.

In this lesson unit from the Science Teachers' Association of Ontario (STAO), students fold paper to explore the properties and shapes of materials that give structures their stability and strength. They record their ideas as they...

This site introduces the iteration of circle inversions and describes the associated properties.

This site introduces the iteration of circle inversions and describes the associated properties.

This lesson plan for primary students gives students hands-on practice in using a ruler and understanding customary measurements, length and width in inches. Students also create simple one and two digit addition problems related to the...

An advanced investigation of Greatest Common Factors (Divisors) and a look at related algorithms and properties) comutative, associative, and more). Contains links to relevant topics.

Based off of the hit television show NUMB3RS, this lesson has students examine a set of transformations to determine if certain properties (such as associativity and closure) exist for equilateral triangles. Students create tables of...

DENSITY is a physical property of matter, as each element and compound has a unique density associated with it. Density defined in a qualitative manner as the measure of the relative "heaviness" of objects with a constant volume. For...

An online activity which illustrates the magnetic property of diamagnetism associated with water. Contains a simple procedure and then a good explanation of the magnetic interactions that were displayed by the grapes.

Everyday we are surrounded by circuits that use "in parallel" and "in series" circuitry. Complicated circuits designed by engineers are composed of many simpler parallel and series circuits. During this activity, students build a simple...

Students are introduced to the concepts of air pollution and air quality. The three lesson parts focus on the prerequisites for understanding air pollution. First, students use M&Ms to create a pie graph that expresses their...

The purpose of this task is to explore reflections in the context of paper folding. Each fold is associated with a line of reflection and understanding each step in the construction requires careful analysis of angles and of the...

The Chinese character mark formerly known as "Tan" is the first of two lessons to introduce first grade students to geometry using tangrams. This lesson incorporates history, math, and language arts. In this lesson students will be able...

How do we recognize this figure as Shakyamuni Buddha? This is the traditional representation of the Shakyamuni Buddha or the historical Buddha. The statue shows the moment of his enlightenment at a place called Bodh Gaya in India, which...

This is a brief biography on the life and scientific work of Otto Stern, a physicist honored with the Nobel Prize in physics for his "development of the molecular ray method and his discovery of the magnetic moment of the proton."

This site provides a chart of properties associated with silver, ranging from silver's melting point to conductivity.
