PRODUCT DESCRIPTION

Lab: The Effect of Concentration on the Rate of Diffusion

Free biology lab perfect for biology or life science students in grades 8-12


PURPOSE: This experiment will explore the concentration gradient by measuring the rate of diffusion in a number of theoretical cells.

The objectives for this lab are:
(1) To define concentration gradient
(2) To explain experimental data concerning different concentration gradients
(3) To complete a data table and prepare a graph to illustrate the data
(4) To apply information from this experiment to other related problems.

MATERIALS: 6 pieces of dialysis tubing, sucrose solutions of varying concentrations, String, Balance, 6 beakers or plastic cups, Stopwatch

NOTE: This product is also included in a large, bundled unit lesson plan and can be viewed here: Cell Structure and Function Complete Bundled Unit Plan
