Abstract

You can measure the viscosity of a fluid using a glass tube and a marble with slightly smaller diameter than the tube. Seal one end of the tube. Fill the tube with the fluid to be tested. Drop the marble into to the tube and measure the time it takes to fall a fixed distance. Repeat the measurement several times, and use the average value. How does viscosity change with the amount of sugar dissolved in water? How does viscosity change with temperature?

What makes it possible to create high-technology objects like computers and sports gear? It's the materials inside those products. Materials scientists and engineers develop materials, like metals, ceramics, polymers, and composites, that other engineers need for their designs. Materials scientists and engineers think atomically (meaning they understand things at the nanoscale level), but they design microscopically (at the level of a microscope), and their materials are used macroscopically… Read more
