Name: ____________________________________________ Date: ________ Partners: ________________________________________ Group: ______ Edible Mitosis In this activity, students will be recreating the phases of mitosis using edible materials. Students will be placed in groups of four, with each member being responsible for one phase of mitosis. THE INSTRUCTOR MUST INITIAL THAT THE PHASE WAS COMPLETED 100% CORRECTLY TO RECEIVE CREDIT FOR THE LAB. Materials: Frosting - glue Skittles (6) - centrioles Twizzlers pull n Peel-cell membrane Twizzlers Pull n Peel - nuclear membrane Jelly beans (6) - centromere Twizzlers pull n Peel - spindle fibers Paper Plates (4)- cytoplasm Starburst- chromosomes and sister chromatids Procedure: 1. The lab manager for each group will obtain the necessary materials. 2. Using your notes and the key above, recreate the phase each phase of mitosis. When finished, make sure you have teacher’s initials for correct phase. MAKE SURE YOU CAN EXPLAIN EVERY CELL PART INVOLVED IN THE PHASES!! ________ Prophase_TEACHER’S INTIAL ________ Metaphase_TEACHER’S INTIAL ________ Anaphase_TEACHER’S INTIAL ________ Telophase_TEACHER’S INTIAL 3. Clean up materials and answer analysis questions. Analysis Questions: 1. The purpose of mitosis is to produce: a. Copies of chromosomes and cells that are different than their parents. b.
