The purpose of this experiment is to see how does a pressure change as the volume of air in the syringe changes. Our hypothesis is greater volume of air then there is a higher air pressure. Independant varible: Volume, which is measured in cm3.
 * Volume || 15 cm3 || 10 cm3 || 5 cm3 || 0 cm3 ||
 * Pressure || 150 kPa || 200 kPa || 375 kPa || 400 kPA ||

Dependant varible: Pressure, which is measure in kPa Constance: Same syringe and the same gas (air).

Liquids oct. 29, 2007
· State in which matter takes shape of its container and has a definite Volume. · To measure liquids you use a graduated cylinder. · Look under the meniscus to find the volume of a liquid. · Liquids contain: density,mass,volume. · The atoms or molecules in liquids move fast enough to over come, some of the attractions between them



In order for a clay boat not to sink you might want to think about having thin walls and sides that curve in. Also your boat will float if your water displacement is around 10g. Then there's a good chance your boat might float.Your floating boat average is 10.7g. This is the amount of water displaced by the boat. If your boat average is 6.23g water displaced there's probably a good chance your boat will sink.

The summary of volume and mass: The data shows no correlation between volume and mass in a specific liquid. Even though the red rod had a large mass with a little volume. This means that the density would also be a large number. So this shows that there is no correlation between the volume and mass of different irregularly shaped objects.

Todays Mission is... Determining which of the Physcial Properties may have had a part in the sinking of the clay boat and collecting evidence that will support our case. Here's the information we have so far. We'll keep you in detail. - To measure mass you use a triple beam balance. - To measure weit you use a newton scale. -To figure out the volume of an object you use a graduated cylinder. - To get things pounded into small sheets you use a mallet. - To find a texture of an object you......... -.............
 * Mass- a matter is made up of mass.
 * Weight- is a measurement of gravitational force acting on an object.
 * Volume- of a solid object is a three- dinensional concept of how much space it occupies.
 * Mallebility- pounded into small sheets.
 * Texture- refers to the properties held and sensations caused by the external surface of objects received throught the senses of touch.
 * Ductility- is the mechanical property deformations due to tensile stress without fracture.

In science class this week with Mrs.Laguna gave us a lab to try to figure out if mass is conserved. Here is the lab data all 6 groups had and the averages we came up with.Our data is under group number 4.At the end of this lab we found out that mass is conserved.
 * Group # || Mass & Water || Mass of Alcohol || Sum Of Masses || Mass Mixed || Diff. ||
 * 1 || 20.8 || 24 || 44.8 || 44.8 || 0 ||
 * 2 || 24.9 || 21.9 || 46.8 || 45.9 || -0.9 ||
 * 3 || 20.2 || 20.6 || 40.7 || 40.75 || 0.05 ||
 * 4 || 24.3 || 21 || 45.3 || 46.7 || 1.4 ||
 * 5 || 24.2 || 22.7 || 46.9 || 46.7 || -0.2 ||
 * 6 || 23.9 || 22.6 || 46.5 || 45.4 || -1.1 ||
 * average || 23 || 22.133333 || 45.166667 || 40.04167 || -0.125 ||
