Phospholipid and Membrane Transport KitExplore the structure of a phospholipid, then construct a phospholipid monolayer. Features include the amphipathic structure of phospholipids with their hydrophilic heads and hydrophobic tails. Additional kit components allow students to construct lipid bilayers and consider how transport proteins move ions and small molecules across membranes.FB2149 I $53.55CELLS, CONTINUEDFLINN SCIENTIFIC I MIDDLE SCHOOL LIFE SCIENCECell Membrane Permeability—Student Laboratory KitThe model organism Saccharomyces cerevisiae provides drama in studying yeast cell permeability and cell membrane function. Use indicators to discover that cell membranes play a vital role in regulating what goes into and out of a cell. Substances’ ability to cross the phospholipid bilayer offers amazing visual evidence for facilitated diffusion and active versus passive transport.2 options available at flinnsci.com$42.35–$92.95Make Your Own Cell— Student Laboratory KitStudents design their own cells, gather internal cell structure materials and use the Flinn Cellgel™ polymer to mold their own unique 3-D models of cells. The easy melt-and-pour polymer sets up as a “permanent” clear gelatin that doesn’t mold and can be stored for years.FB1612 I $47.50Plasma Membrane ModelBring the fluid mosaic membrane out of textbooks and into the classroom with this model. Students view molecular structure of the phospholipid molecules and membrane structure as a whole. Rock the model back and forth to demonstrate the membrane’s fluid nature. Model includes a membrane protein that can be moved with a magnet to represent different membrane proteins and show how the membrane structure is not disrupted by the protein motion. FB1768 I $57.50The Cell Cycle—Simulations of Chromosome Behaviors—Super Value KitLet students model the processes of mitosis and meiosis with hands-on chromosome simulation materials. Magnetic centromeres and pop bead arms allow students to visual-ize and compare the two processes. Built by students, the chromosome models can be physically manipulated through the various stages of the cell cycle. FB1443 I $132.70
