Ellipse_Drawer

The Dutch mathematician Franz Van Schooten (1615-1660) came up with a simple device for drawing ellipses. As the point O is dragged along the horizontal axis, the point P (pen) traces out an ellipse. ........ Green flag to start - Space bar to clear.

Ellipsograph_Proclus

An ellipse drawer attributed to Archimedes (or trammel construction). The point A is attached to the horizontal axis in such a way that it can slide along the axis. Similarly, the point 0 is attached to the vertical axis and allowe to slide along it. The point at the end of the segment traces out an ellipse................. Green flag to start.

ellipse000

An ellipse can be defined as the locus of points, the sum of whose distance from two fixed points (the FOCI E1, E2) is constant. Green flag to start.

Champs(9-12)

Champs(9-12) Imagine, a magnetic field (champ magnétique in french) and magnetized needles. Imagine a field (un champ) and squalls of wind. Imagine a brook and whirlwinds. Imagine, last but not least, the differantial equations... For others champs : Look at Champs (1-4).and Champs(5-8) ----------------------------------------------------------------+Use the slider bar to change the champs+Use the slider bar to change the needles. And press on the green flag ...----------------------------------------------------------------Those i prefer : C10 N7 ; C9 N16 ; C11 N3 and C12 N6 . Send me the parameters of those you like ! -------------------------------- Suite de Champs(5-8), je prépare Champs(13-16)

this is a remix of peterthegeeks spectrum by lines so I could see how it worked

Orange_Square,_Purple_Circle[1]

What Scratch projects could start with a square and a circle? Reimagine, recreate, and remix me! -________-________- note: works better offline, its a bit laggy online

Enter the two numbers and the function and the npress enter to make this calculator calculate

Curlicues

Press the green flag *********************** Ten examples of fractal curlicues . A special program for Scratch .Physicists will recognise a curlicue as a discrete version of Cornu's spiral in optics, and indeed curlicues can be interpreted as diffraction experiments too. ********************** Use the sliders to choose examples and colors and press the green flag. ********************** Reference: F. Berry and J.Golbert,"Renormalisation of Curlicues"in Nonlinearity n°1

GeoShapes

You can make many different shapes with this exciting 7 piece puzzle. GeoShapes Consist of two right, an equilateral and an isosceles triangles, a rectangle, a Kite, and a parallelogram. You can make many interesting shapes with these pieces and many important concepts in geometry can also be explored with them. Press Competition to see how you can remix your own version of GeoShapes and later enter into a competition that will be announced. I would like to thank my collaborator ffred for all his great comments and testing and debugging the project. I have borrowed the chimes from 97Castle's Music Balls. Thanks 97Castle. ***(Last Update 9/24/2008)*** Entry 1 - Right Fist by ffred

TRIGRAM

You can make many different shapes with this exciting nine-piece Tangram like puzzle. Consisting of one large, three medium and five small right triangles, these TRIGRAM pieces can be arranged to show many geometric relationships for a variety of interests: dinosaurs, aircraft, animals, people, geometric figures, Alphabet and more! To get your plastic copy packed in a CD-style plastic case for easy storage. go to www.stokespublishing.com or Call 1-800-550-5254 The puzzle booklet that is enclosed will motivate your creativity with 75 different designs I would like to thank my collaborator ffred for all his great comments and testing and debugging the project.

Pattern Blocks

You can make a lot of interesting designs and tiling with Pattern Blocks. Have fun! Pattern Blocks also form the basis of a number of mathematical activities in schools. I will make some of these later but please go ahead and remix this project to make your activities in Scratch. I would like to give credit to Jacobo Bulaevsky who made the first Pattern Blocks on the Web in 1998. This version owes much to his work. I would also like to thank my collaborator ffred for all his help and comments on all my virtual manipulative projects.
