Show your students that algebra and trigonometry can be close to their heart. These are .gif images of Valentines drawn from Math Equations. The equation for each heart is written at the top of the Valentines. There are six different equations that produce a heart shape. Some of the Valentines have been drawn as Fractals. The images have a transparent background, so they can be drawn on top of text or other pictures in a Word document. Black and white versions are included so they can be

The Dragon Fractal Lab is a computer program that draws fractals of the Dragon Fractal type. Students adjust the fractal parameters to draw many interesting fractals. They are encouraged to experiment with the parameters to create fractals of their own. A Microsoft Word lab book is included that guides the students through the process and includes several preset examples for them to explore. Junior High and High School Math students and Computer Lab students should enjoy making these fractal

These 10 math valentines are GIF images of hearts produced on the computer using polar coordinates. The equation used to generate the hearts is written at the top of each valentine. The background is transparent, so the pictures can be printed on colored paper or in documents allowing the background to show through. Use them on documents that you hand out to the students, or let the students place the images on paper and make their own valentines. Although the Valentines can be used by child

This is a mystery story about a group of high school students who attempt to investigate a secret moonshine operation, but fail miserably. Their misled antics do result in one positive note when they provide a valuable clue that helps the police capture the ring leaders of a drug operation. The students learn to listen to their teacher and obey his directions trusting that he knows best. They also learn that it is dangerous to prejudge people on first impressions. The text is laced with sci

This is a story about some young science students who while attempting to perform an experiment in ocean wave modification discover a mysterious substance that is causing local wildlife to go crazy. They find that not only does the mysterious substance cause psychological effects, but their experiments are affecting wildlife too. Their attempt to create an underwater parabola to focus the waves into a fountain in Looking Glass Bay ends in a disastrous shipwreck. It is a learning experience fo

A 1-page handout showing the math equation for drawing a 3-leaf and 4-leaf shamrock using polar coordinates. A graph of the equation using the Cartesian Coordinate System is included for comparison of the two coordinate systems. Students can use the equations in Excel, a graphing calculator, or other software and play around with the formulas. Instructions are not included.

This is a software app in which students create fractal Christmas Trees and decorate them. Math equations are provided for each component of the tree and decorations. An easy user interface allows students of all ages to draw a tree and decorate it, then save their creation to an image file for printing or adding to another document. The sample tree pictures show some of the hundreds of possibilities for tree design. You need to have Java loaded on your computer to run this executable.

This packet consists of a five page Microsoft Word document describing how rainbows are formed and five computer simulations tied to the text to reinforce students understanding of the concepts of rainbow formation. This computer lab material was written by Dr. David Long who believes in using computer simulations to reinforce student interest and understanding of concepts. The product can be used as a high school or college physics or general science lab in studying the formation of a rainbow
