(This is our graph!) __ Two experiments involving surface tension: One experiment involved putting pennies into a glass filled to the rim with water. When pennies were put into one glass many times no water came out. but in the other glass we found out there was a small amount of soap in the glass which caused water to constentley spill out. The force acting on the particles at the surface of a liquid that causes the liquid to form spherical drops is Surface Tension. The other experiment involved a pan full of water, soap, toothpick, paper boat, and surface tension. A paper boat with a key shaped hole was placed into a pan full of water. Then a toothpick with a small amount of soap was touched to the boat the boat swam away then. When the soap was added the surface tension changed which caused the boat to move through the water pan on its own. __period 1 group 1 wikispace__** Time ( s ) Absolute Absolute Pressure, Run #4 Time ( s ) Absolute Pressure ( kPa ) Absolute Pressure, Run #4 Time ( s ) Absolute Pressure ( kPa )**

 * Boats sometime float and sometimes sink for several reasons: The walls of the boat made thinner help the boat float and curved walls help the boat float. But if the boat is too heavy or not built right it will sink. If the boat flaots it should displace about 10g of water, because there is 10g of clay. a floating boat average is 10.7g. If the boat sinks the average water displaced is about 6.23g. The density of the clay is about 1.67g/cm. Therefore boats will only float if they are made a certain way. They will other wise sink.**

Gas is the state in which matter changes both shape and volume. The amount of empty space in a gas can change. The atoms or molecules in a gas move fast enough to break away completely from one another. Particles of gas move very fast. The relationship between the volume and pressure of a gas is know a the Boyles law because it was first discribed by Robert Boyle an Irish chemist. Boyles law states that a fix amount of gas at a constant temperature the volume of a gas increases as its pressure decreases.**
 * __Gasses__

SUSPECTS __MASS__: the amount of matter something is made up of. The triple bean balance is how you measure the mass. measured in grams.**
 * __MISSION POSSIBLE__

The graduated cylinder is used to measure.
 * __VOLUME__:The amount of space that something occupies or the amount of space that something contians

__WEIGHT__: a measure of the gravitational force exerted on an object, usually by the earth.

__TEXTURE__: How something looks or feels.

__MALLEABILITY__: The ability of a substance to be pounded into thin sheets.

COLOR: red, blue, purple......

DUCTILITY: the ability of a substance to be drawn or pulled into wire.

INERTIA: big, hard to start and hard to stop.

WHAT WE THINK: Some of us think it has to do with weight and others of us think it has to do with shape or maby even all the suspects have something to do with it.**


 * MAIN SUSPECTS: Weight and Inertia.**

The data shows no coralation. In one case the volume was greater than the uolume but the others mass was greater. (The screw and rod.) In another case the volume of the prism was 8cm and the mass was 23.0g and the spacers was 5cm and its mass was 6.5g. The dots on the graph are all different. This concludes that the data shows no coralation**
 * Mass and Volume of Iregularlly Shapped Objects



intresting that group 1 had no difference. This concludes that mass is conserved**
 * Class data experiment**
 * Mass was conserved in this experiment. The mass of the alchohol and water is seperately measured and averaged at about 45 grams. Massed together they were 45 grams. It was




 * This is a drawling of our group. This was part of our story.**
