Please work through your Science in your journals...due Thursday please...be ready for a quiz on viscosity on Thursday.
Science 8: Viscosity
Please complete the following tasks in your Science
journal. You will have a quiz on
Thursday on viscosity. Please ensure
that your work is neat, complete, organized, supported with detail, and in
order.
1.
Watch the Pitch Test video…take a few jot notes.
2.
Create a visual journal page for the words
viscosity, viscous, flow rate. Include
definitions, diagrams, examples. Use
each word in a sentence.
3.
Complete Determining Flow Rate Demo…we will do
this as a class on Tuesday. Calculate
flow rate for each liquid.
4.
Take some notes from your textbook from p.
45-49. Pay close attention to:
Product performance viscosity of liquids &
temperature
Viscosity of gases & temperature superfluids
5.
How does temperature affect the flow rate of
liquids? Explain using particles.
6.
How does temperature affect the viscosity of
gasses? Try your best to explain using
particles.
7.
Read Investigation 1-G Flowing Fluid Floods
City. Answer questions #1-4.
8.
How are viscosity, the size and shape of particles,
and internal friction related?
9.
Asphalt is the black, sticky material that binds
gravel in the pavement that covers streets and highways. Explain why paving is almost always done
during the summer months.
10.
The lower the SAE (10,20,30,40,50) grade of oil,
the faster the flow rate of the oil.
Explain which type of oil you should use in a car engine in the
summer. Explain why you chose this grade
of oil. Explain which type of oil you
should use in a car engine in the winter.
Explain why you chose this grade of oil.
Remember to connect your responses to particles!!
