Presentation Transcript

  1. Viscosity 6th grade science (integrated with art)

  2. Featured Artist: Laura Trevey

  3. Featured Scientist: Jean Louis Poiseuille (1799 - 1869) • Poiseuille is pronounced “pwaz” . The French do not sound out the vowels “U”, “I”, “E,”, or the letters “LL”. • He was a doctor who wanted to learn more about blood pressure. This led him to preform tests on the resistance of liquids. • The equation for flow of liquids through a tube is called Poiseuille's Law.

  4. Viscosity • Determines the amount of friction, which in turn determines the amount of energy absorbed by the flow. • The thicker the substance, the more friction between the molecules there will be. • More friction = slower flow

  5. What substance flows easiest? • Honey • Soap • Soda • Salsa

  6. WHY??

  7. Color wheel • The natural progression of colors. • Defines the light value of color.

  8. Directions • Get into groups of 3 and 4 • Find supplies and set up a station in the classroom that has plenty of space and will not be disturbed. • Discuss with your group what you need to do in order to complete the whole project (including experiment and poster board)

  9. Supplies • Four 50 ml test tubes • Three liquids of your choice and one water • Poster board • Markers • Tape • Stop watch
