Observing Deformation

WARNING: Do not taste or eat any lab materials. Wash hands when finished.

Procedure

1. Remove the wrapper from three bars of taffy. 2. Hold a bar of taffy lengthwise between your hands and gently push on it

from opposite directions. 3. Hold another bar of taffy and pull it in opposite directions.

Analysis

1. Which of the procedures that you performed on the taffy involved applying tension? Which involved applying compression?

2. Infer how to apply a shear stress to the third bar of taffy.

Modeling an Eruption

Procedure

1. Place red-colored gelatin into a self-sealing plastic bag until the bag is half full.

2. Seal the bag and press the gelatin to the bottom of the bag. 3. Put a hole in the bottom of the bag with a pin.

Analysis

1. What parts of a volcano do the gelatin, the plastic bag, and the hole represent?

2. What force in nature did you mimic as you moved the gelatin to the bottom of the bag?

3. What factors in nature cause this force to increase and lead to an eruption?

Disruptive Eruptions

Lab Preview

Directions: Answer these questions before you begin the Lab.

1. Why are safety goggles especially important when doing this lab?

2. Based on what you know about the activity from question 1, what can you expect to happen that might resemble a cinder-cone volcanic eruption? Explain.

A volcano's structure can influence how it erupts. Some volcanoes have only one central vent, while others have numerous fissures that allow lava to escape. Materials in magma influence its viscosity, or how it flows. If magma is a thin fluid--not viscous--gases can escape easily. But if magma is thick--viscous-- gases cannot escape as easily. This builds up pressure within a volcano.

Real-World Question

What determines the explosiveness of a volcanic eruption?

Materials

plastic film canisters baking soda (NaHCO3) vinegar (CH3COOH) teaspoon 50-mL graduated cylinder

Goals

Infer how a volcano's opening contributes to how explosive an eruption might be.

Hypothesize how the viscosity of magma can influence an eruption.

Safety Precautions

Procedure

1. Watch your teacher demonstrate this lab before attempting to do it yourself.

2. Add 15 mL of vinegar to a film canister. 3. Place 1 teaspoon of baking soda in the film

canister's lid, using it as a type of plate. 4. Place the lid on top of the film canister,

but do not cap it. The baking soda will fall into the vinegar. Move a safe distance away. Record your observations in the Data and Observations section. 5. Clean out your film canister, and repeat the lab, but this time cap the canister quickly and tightly. Record your observations.

WARNING: This lab should be done outdoors. Goggles must be worn at all times. The caps of the film canisters fly off due to the chemical reaction that occurs inside them. Never put anything in your mouth while doing the experiment.

Data and Observations

Trial 1 2

Observations

Conclude and Apply

1. Identify Which of the two labs models a more explosive eruption?

2. Explain Was the pressure greater inside the canister during the first or second lab? Why?

3. Explain What do the bubbles have to do with the explosion? How do they influence the pressure in the container?

4. Infer If the vinegar were a more viscous substance, how would the eruption be affected?

Communicating Your Data

Research three volcanic eruptions that have occurred in the past five years. Compare each eruption to one of the eruption styles you modeled in this lab. Communicate to your class what you learn.
