Diffusion across a Selectively Permeable Membrane
7th - Higher Ed
Lab groups fill a section of dialysis tubing with glucose and starch solutions and suspend it in a water bath. They use iodine as a starch indicator and a glucose test strip to find out if either of the materials crossed the selectively...
Cell Division: Frog Egg Division Observation and Modeling
7th - 9th
Students create and test a hypothesis about cell division. After observation of Frog Egg cell division, students write obervations and refine process and hypothesis. The use of scientific method, group work and inquiry are fostered by...
Cell Size and Shape; Diffusion and Osmosis Processes
9th - 12th
Use salmon eggs as a cell model for demonstrating the movement of water over concentration gradients. Junior scientists examine the same process microscopically with an onion cell. They use a thistle tube and a semipermeable membrane to...
AP Chapter 9: Respiration - Extra Credit 3 Peter Mitchell & How Cells Make ATP
10th - Higher Ed
Critical thinking is required to answer these five questions on cellular respiration. Advanced biology learners consider transport across the mitochondrial membrane and the metabolic pathway in ATP synthesis.
