Fitting Conics by Martin Cantos I. Objectives: - to apply the knowledge about conics to make useful things - to know the difference between a circle, ellipse, parabola and hyperbola II. Description: A regular box with four holes on it, one hole is shaped as a circle, the other is shaped as an ellipse, another shaped as a parabola, and another shaped as a hyperbola. Outside the box, there are four solid objects, one shaped as a circle, another shaped as an ellipse, another shaped a parabola, and another shaped as a hyperbola. Each solid object corresponds to hole in the regular box. Can you fit the objects in the regular box? III. Materials: - regular shaped box (shoebox), scissors, compass, ruler, pencil, cartolina, tape, pentel pen IV. Procedure: 1. Using the scissors, cut holes shaped as a circle, ellipse, parabola and hyperbola on the rectangular box. 2. Measure their sizes, then make the solid objects congruent to the holes, one as a circle, ellipse, parabola and hyperbola 3. Use the cartolina, masking tape, and scissors to do these objects. Make sure that they have the same measurements as the holes in the box. 4. After making the objects and the box, you can design them. V. Applications/Uses: This instrument can be used by children. This will test their skills in logical thinking and cognitive reasoning. This instrument can be helpful for their development. VI.
