CELLS, CONTINUEDExploring Plant and Animal Cells—Student Laboratory KitStudents identify and label the parts of animal and plant cells to understand func-tion and variance between the types of cells. Students prepare and stain their own plant and animal cell microscope slides, sketch them and then compare and contrast their sketches of prepared slides. 2 options available at flinnsci.com$47.85–$76.60Prokaryotes vs. Eukaryotes— Super Value Microscopy KitDiscover the key features differentiating prokaryotes and eukaryotes. Students micro-scopically observe and analyze four cell samples and then sketch observations and determine classification. Includes 8 slides, two of each sample, for 8 lab stations. FB2013 I $46.05Introduction to Osmosis and Diffusion—Student Laboratory KitBring passive cell transport to life by creating artificial cells with dialysis tubing and simulated cellular fluid of glucose and a special dye. Dye diffusion is directly observed, mass and volume measurements prove osmosis of water takes place, and glucose test strips confirm molecules diffus-ing through the cell membrane pores. FB1870 I $43.55MIDDLE SCHOOL LIFE SCIENCEDiffusion Demonstration ModelStudents love this functioning diffusion model. The semipermeable membrane in the center of the model allows the passage of “small” molecules while keeping the “large” molecules trapped on one side of the membrane. Randomly shake the model and watch what happens! FB1573 I $22.35Cell Size and Diffusion— Student Laboratory KitWhy are cells so small? Wouldn’t larger cells be more efficient? The answers are obvious when students cut open stained agar cells and see the diffusion pattern for themselves. Measurements and calculations in this hands-on laboratory dramatically clarify the concept of surface area-to-volume ratio, a key concept in understanding cell size limitations.2 options available at flinnsci.com$45.45–$77.70See flinnsci.comfor more kits
