*Note: This is an abbreviated Project Idea, without notes to start your background research, a specific list of materials, or a procedure for how to do the experiment. You can identify abbreviated Project Ideas by the asterisk at the end of the title. If you want a Project Idea with full instructions, please pick one without an asterisk.
AbstractYou 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?

Materials Scientist and EngineerWhat 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 (at the level the eye can see). From heat shields in space, prosthetic limbs, semiconductors, and sunscreens to snowboards, race cars, hard drives, and baking dishes, materials scientists and engineers make the materials that make life better.
