1.4.2 Investigating cell division Pupils look at prepared slides of cell division through a microscope. Their task is not to consider individual chromosomes but just look at the cell and the whole nucleus and determine the sequence of events that starts with a single cell and ends with a cell that has divided into two.
Pipe Cleaner Prep Teachers guide to set up the activity using pipe cleaners to represent chromosomes. You'll need lots of white pipe cleaners to represent the autosomes, then pink and blue to match the sex chromosomes. Bead colors can vary
1. Cut the pipe cleaner in half. Press down the cut ends of the pipe cleaner with the point of a pencil so that they are not sharp. 2. Place the two halves of the pipe cleaner together. 3. Place both pipe cleaner halves though the bead. 4. Move the bead approximately to the center of the pipe cleaner halves. 5.
Mitosis and Meiosis Introduction There are two types of nuclear division, mitosis and meiosis. Mitosis is usually used for the growth and replacement of somatic cells, while meiosis produces the gametes or spores used in an organism’s reproduction. Mitosis is the first of these studied in this lab. It is easily observed in … Continue reading "Lab 3 Sample Ap Mitosis & Meiosis"
Modeling Nucleic Acids with Pipe Cleaners, Beads, and Paper Clips - Science and Math with Mrs. Lau A while ago, I brainstormed and came up with some bead and pipe cleaner activities to help my students model proteins, carbohydrates, and lipid molecules.
