Title: Earthquake Lab, Gianna Milano and Jack kennedy and Jess Anderson Teacher, Mrs Meyers and Mr Sheng Date January 8 2012
Lab Question/Problem: How do the Earth’s plates sometimes stick and then move past each other?
Hypothesis: If I make a model of an earthquake, then I can better understand how an earthquake occurs.

Materials: Cup, water, sticky notes ,

1. Stick the self-stick note to a table. Be sure that about 1 in. of the short side of the self-stick note is hanging over the edge of the table. Also make sure the self-stick note is firmly stuck in place.
2. Fill the cup ¼ full with water. Place the cup on the center part of the self-stick note that is on the table.
3. Carefully and firmly pull the self-stick note straight out from under the cup. The sticky part of the note will stop you from easily pulling it all the way out. Observe what happens to the water.

Observations: add observation - what happened to the water? I observed a vibration in the cup of water, it was little ripples of water going in all directions.

1. How is snapping your fingers like the movement of the self-stick note?
answer this It sticks for a second then, then snaps away quickly. If you do it slowly you can feel the vibrations from your fingers when it pulls away.
2. What did you observe about the water in the cup when you pulled on the self-stick note? answer this I observed the water ripple alot when I pulled the self stick note.
3. Scientists often infer things based on their observations. What can you infer might happen when plates are moving past one another if the pressure between the plates is suddenly changed? answer this I can infer that the vibrations most likely will cause an Earthquake, No one can predict how strong it will be . You have to wait and see the richter scale.

Title: Volcano Lab, add your name, your lab partner's name, teacher names, and date. Gianna Milano my partners were Jack Kennedy and Jess Anderson, Teachers Mrs Myers and Mr Sheng January 8 2012
Lab Question/Problem: How is a volcano like a balloon?
Hypothesis: If I make a model of a volcano, then I can better understand how a volcano occurs.

Materials: add materials Two 1 litre bottles and one 2 litre bottle. Two air pump's one electric and one manual , Rice cereal .

1. Attach an air pump to the hole in the bottle that is filled with rice cereal.
2. Pump air into the bottle. Observe what happens.

Observations: add observations - what happened to each bottle and why do you think what happened happened? The first bottle 2 litre bottle cap fell off when we pumped air into it. The one litre bottle with the most cereal did not shoot out ceral there was not enough air pressure in the bottle. The second one litre bottle with less cereal had the most pressure ,so the cereal came out the top the most.

1. What happened to the cereal when you pumped air into the bottle?
answer this It came out the top. Each bottle had a differn't observation because the amount of cereal was not the same in each one.
2. How could you make more cereal shoot out of the bottle? answer this The more air with less cereal shot out the most. I think it was because there was the most air pressure in that bottle.
3. Scientists often make a model to help them understand things that happen in nature. How is the bottle used to model an erupting volcano?
It showed that when pressure builds up in the the bottle it explodes up and out. When pressure in the Earth builds up it causes the lava to shoot out the volcano.
