*An astrolabe is an ancient tool used in solving problems that involve time and the position of the Sun and stars. Astrolabes can be used in timekeeping, surveying, geography, and astronomy to name a few disciplines. One of its most well-known uses is navigation.
Drawing papers, pencil, eraser, scissors, ruler

Copies of the prototype model for inspiration and to give ideas to students
Colored pencils, sharpies (black and assorted colors)
fasteners (for connecting various parts and for rotation)
Step 2. Students use 1-2 mixed-media papers to create their volvelles: Students will use available templates in the classroom to trace the 2 volvelles circles and divisions on their mixed-media paper (see below for image 1, for the template. Teachers should copy image 1 for students to use. There are 2 circles that need to be traced separately and the opening needs to be cut out using a Xacto knife to reveal the information). Students tape this template to their mixed-media paper and trace each circle, 1 at the time and separately, using a pencil by "indentation." Students must indent the center of the circle each time to identify where the fastener must go through for joining the 2 circles. Process of indentation: Students need to press hard enough so that the volvelle's template creates an impression on the mixed-media paper. After they see the impression, students may trace it with a pencil or a pen to make the volvelle's traced lines darker.
Step3. Students add details such as numbers, illustrations, colors, texts, etc., according to their chosen subjects, to their traced volvelles and then cut 2 circles out. The volvelle reveals information about fruits and veggies. Information could be calories, vitamins, fibers, etc.
Step 4. Students assemble the 2 circles using a fastener in the center to finish their volvelles
