Liquid
Travel Time 1st 2nd 3rd Average
water
syrup/honey
cooking oil
ketchup
Guide Questions:
1. Is your prediction correct?
2. Which liquid is the most viscous? How do you know?
3. Which is the least viscous?
4. Compare how these liquids flow with how you think lava flows. Why does
some lava travel faster than others?
Part B
1. Put 100 mL syrup in a clear glass.
2. Using a drinking straw, blow some air from the bottom the liquid.
Observe.
3. Repeat procedure 2 by blowing harder from the bottom of the liquid.
Observe.
Guide Questions:
1. Compare the movement of the liquid as the bubbles move on the
surface.
2. In this activity, you have observed that different liquids have different
viscosities. If the liquid represents the magma, then its rate of flow depends
on several factors.

Answer: Q1. Is your prediction correct?
Q2. Which liquid is the most viscous? How do you know?
Q3. Which liquid is the least viscous?
Q4. Explain viscosity in your own words.
Q5. Compare how these liquids flow with how you think lava flows. Why do some types of lava travel faster than others?
Answers
1. Indeed, my prediction is correct.
2 based on Table 2 travel time seconds, the oil is the most viscous.
3. The least viscous honey
4. Viscosity is the time taken, or how long it takes for a liquid to flow.
5. The more viscous the liquid, the longer it takes to flow. Many types of lava flow quicker than others because of factors influencing the magma temperature chem composition and the amount of gas it contains, if it has a high temp low content of silica and more gasses it becomes less viscous, and is easier to flow.

Explanation: sometimes it is yes but sometimes it is no because when you are predicting,there is no confirmation on your prediction unless you test with an experiment and you gathered informations about it to confirm that your prediction is correct.
