1. Using the glossary of your book, please look up the definitions of the following words

a. Viscosity
b. Volatiles

2. Name a substance that has HIGH viscosity _____________________________

3. Name a substance that has LOW viscosity ______________________________

4. List three (3) qualitative observations you made while watching the video of Pahoehoe lava flow.

5. List three (3) qualitative observations you made while watching the video of A'a lava flow.

Different liquids have different viscosities due to their chemical makeup.Other factors can affect the viscosity of certain liquids. Today we are going to compare the viscosity of water and corn syrup. We will then look at the effect of temperature on the viscosity of the corn syrup.

6. Question:

7. Hypothesis:

8. Data collection:

Water and Corn Syrup Viscosity Data

9. Analyze & Results:

Questions:

1. Which has a higher viscosity, water or corn syrup?

2. What effect did heating and cooling have on the viscosity of corn syrup?

3. What are the two factors that affected viscosity in today's lab?

4. What are the two factors that specifically affect the viscosity of magma in a volcano that we looked at in this lab? What is one factor that affects the viscosity of magma in a volcano that we didn't look at?
