With the goal of making chemistry understandable, this site guides the learner through electron configurations with layman's terms, colorful illustrations, and questions to check learning along the way. The "Purney Cheer" is also...

Dr. Math, in a reply to a student question, shows how to derive the equation of a parabola for situations when the line of symmetry is not || to one of the axes.

The symmetry of a trangle on the coordinate plane is discovered through the 2X2 matrix transformations.

In this chemistry field/class based activity, students investigate snow and, more specifically, why snowflakes have six sides. Students will individually fossilize a snowflake and observe similarities and differences with other members...

A survey of math graphing techniques includes horizontal and vertical shifts, stretching, lines of symmetry, even and odd functions, and absolute value functions.

Learn how to construct convex polygons and the mathematical foundations of symmetry on this site.

Shapes is a fun educational activity to help children learn basic properties of simple geometric figures. Children will practice looking for differences and similarities between shapes to complete puzzles. Shapes! gets progressively more...

[Free Registration/Login may be required to access all resource tools.] This lesson covers how to find the x-intercepts, vertex, axis of symmetry, and y-intercept of a parabola.

[Free Registration/Login may be required to access all resource tools.] The word "worm" is not very scientific. But it is a word that informally describes animals (usually invertebrates) that have long bodies with no arms or legs. Worms...

This StudyCards stack tests students' understanding of translation, transformation, symmetry, dilation, and rotation of a point to form images. Teachers require TI StudyCards Creator Software and students will need the StudyCardApp on...

Review inverse functions with your students using this TI-83 activity. Students will find inverses of given functions, determine whether the inverse is a function, graph both, and check for symmetry through the line y=x. The lesson...

Drag shapes in this geometry and symmetry practice activity.

This task has students link their intuitive notions of symmetries of a triangle with statements proving that said triangle is unmoved by applying certain rigid transformations. The mechanism through which students do this is via...

Given an equilateral triangle, students are asked to explore its symmetries using rigid transformations of the plane. Aligns with G-CO.B.

This article summarizes some key takeaways from a conference on urban design that was hosted by Tufts University. The author describes five innovative ideas for changing cities to make them more interesting and appealing. These include...

The Last Judgement was a common theme in church art, but Michelangelo's interpretation was entirely novel. His vision of the Apocalypse is a swirling maelstrom, filled with thick-set and muscular naked figures. Traditional symmetry and...

This MathWorld tutorial provides detailed overviews of the concepts and theorems associated with geometry. Most of the Math World sites are extensive and some require higher math knowledge to understand, links to terms and topics are...

An excellent compilation of activities that engage parents and children in math explorations at home. Detailed lessons covering a wide range of math topics such as fractions, measurements, money, data collection, and math in newspapers....

If art and math are both passions of yours, this project is meant for you! Spidrons are geometric forms made from alternating sequences of equilateral and isosceles (30 degrees, 30 degrees, 120 degrees) triangles. Spidrons were...

So you've just heard the "Happy Birthday" song and now it's time to blow out the candles. If you are sitting far away from the candles, you know you'll have to blow harder to get them all out than if you were sitting closer. In this...

Have you ever heard the expression "a canary in a coal mine"? In the 1900s and earlier, coal miners brought canaries with them into the mines to act as early warning signals. The canaries were very sensitive to low levels of dangerous...

This online biology book chapter offers definitions and descriptions of the nervous system's components.

This task challenges a student to demonstrate understanding of the concept of measurement.

This website from the John Singer Sargent Virutal Gallery is a very nice website with detailed information on John Sargent's painting, "Lady Agnew." Good quotes, analysis of the painting in comparison to other Sargent paintings, and very...
