Learning targets for this lab
Students can describe a Non-Newtonian fluid.
Students can describe how this substance changes viscosity with pressure.
Students can use terms related to the viscosity of materials.
Students can describe what a non Newtonian fluid is.
Students can describe how this substance changes with pressure.
Students can describe thixotropic and dilatent.
Ideas for hypothesizes: (these are not hypothesis yet.)
How would it act under vibration?
How would different temperature objects affect the substance?
How would different shape objects affect the substance?
Does this substance show thixotropic or dilatent behavior?
Propose a new hypothesis to the instructor for approval.
Cups Mystery substance Water
Don’t eat the substance
Keep your area clean
Not part of the lab but fun to try:
Quickly poke substance with your finger then slowly push finger into material
Pour into hand and roll into a ball
Go outside and toss to a friend. See how far apart you can get.
Cover work area with a piece of paper.
1. Mix material until it is a thick liquid
2. Depending on your hypothesis you should do some of the below procedures.
3. Take material to the caster or other vibrating surface
4. Place a ball of it and see how long it take to flatten (time it with clock)
5. Take same size ball and see how long it takes with the vibration off.
6. or Time how long it takes to make a circuit of the cup with your finger when you are pushing hard, then time it when you are not pushing hard.
7. or Time how long it takes for a warm object to circle the inside of you cup (your finger) then time how long it takes for a cool object (a pencil) to do the same.
1. In your own words explain how this material is able to change from a solid to a liquid and back with only pressure?
2. Please list 2 factors that would limit how far you could throw a ball of this material.
3. Please describe the types of non-Newtonian fluids
Two ways to explain the behavior
