The Speed of the Bubble Tube Set consists of three 22-inch-long transparent plastic tubes containing colored fluids with three different viscosities. A bubble in each tube rises at a constant speed which depends on the type of fluid, the angle at which the tube is inclined and, to some extent, the temperature. This great introductory activity gives students practice setting up experiments, graphing data and making predictions. Each set of tubes comes with complete instructions.
Perfect for teaching the concepts of precision, accuracy, graphing, slopes, uncertainty and extrapolation. Great beginning of school activity for science students of all ages.
