We are Mrs.Laguna's favorite group and we all despise potatoes and love science. DOWN WITH THE RED SOX!!! [] Plane Lab Question: Does the surface area of the wings change the distance of the airplane Hypothesis: the more surface area of the wings will make it fly farther IV: How you throw the airplane(Same person throwing it) DV: How far the airplane goes Constants: How you throw it, number of planes, who throws the planes, weight of the airplanes, number of sheets of paper to make an air plane. diagram ||= Test 1 ||= Test 2 || Test 3 || Avg ||
 * = procedure
 * = plane 1 ||= 4.56m ||= 7.6m || 6.08m || 6.08m ||
 * = plane 2 ||= 7.56m ||= 8.17m || 9.69m || 8.47m ||
 * = plane 3 ||= 8.72m ||= 10.4m || 7.07m || 8.73m ||

Summary:Our group found that by having a bigger wingspan on our plane, made it fly less futher than the ones with a smaller wingspan. So the answer to our hypthosis was No, the bigger the wingspan, the less futher it will fly. Our dependent variable was how far the airplane goes, and the independent was how you throw it and the suface area of the wings.

Mass and Volume Lab

Question: Does the mass of an object affect its volume Hypothesis: No, because mass is the measure of grams, or the measured weight of an object, and volume is the measure of centimeters cubed, or the length of an object. Dependent variable: zeroed out scale, gradulated cylinder at fifty milliliters Independent variable: mass and volume Constants: triple beam balance, gradulated cylinder


 * Object || Mass || Volume ||
 * Aluminum Prism || 22.8 || 8 ||
 * Nylon Prism || 23.6 || 20 ||
 * Plastic Screw || 10.6 || 10 ||
 * Nylon Spacer || 6.5 || 6 ||
 * Copper Cylinder || 56.9 || 6 ||



Summary: We learned through this lab that the volume of the objects does not depend on the mass of the objects. Through various experiments on many objects, we have learned how some objects that look lighter, but their density is the highest. Some objects look heavier than others, but their density is teh highest.

Clay Lab Question: Does the mass of the clay affect its volume? Hypothesis:No, because mass is not directed impacted by volume. Independent Variables: Mass Dependent Variable: Volume Constants: Shape, same type of clay


 * Clay Size || Mass || Volume ||
 * Small Ball || 6.3 || 3 ||
 * Medium Ball || 11.5 || 6 ||
 * Large Ball || 21.4 || 12 ||



Summary Our question for our clay lab was "does the mass of the clay affect its volume?" Our hypothesis was that it wouldn�t but it turns out that it actually does. Since we measured the mass and volume of objects made with the same substance the mass is then directly affected by its volume. That�s why it turned out that mass is directly affected by volume if the objects are made with the same substance. the only way it wouldnt directly impact the volume is if the objects were hallowed out with the same amount or clay.

Marble Lab Question:How does the density of Five marbles, compare to the density of one marble? Hypothesis: Yes, because the density of an object will always stay the same. IV: Marbles DV:Density Constants: 50mL of water, number of marbles.

Summary: We found that the density of five marbles, is the same as the density of one marble. Density is a characteristic property of matter, so no matter how small or big the items are, they will have the same density. In this case, the density stayed the same for five and one marble.

Ice Lab

Question:What happens to the mass of ice as it melts? Hypothesis:We think that it will decrease because the air will be let out of it, making it lighter. DV:State of Matter IV: Mass of Ice Constants: amount of ice


 * Procedure || mass of ice || mass of water || change in mass ||
 * Test || 16.7 || 16.7 || none ||

Summary: Our group found that the the mass of the ice has not changed when it has turned to ice. This means that the same amount of water in the ice, has not changed while going through the stages of water to ice. Our hypothesis was wrong, the mass of the ice did not change because of the air was let out of it.

Temp. Lab ( Dry) Q. What will happen to the temp of the thermometer it you fan it? H. We think that the temp of the thermometer will go down IV. fanning DV. temperature C. person fanning (this graph goes in the interval of 20 seconds) average || stop average || overall average ||
 * speed || start || stop || start || stop || start || stop || start
 * slow || 26.2 || 26.1 || 24.8 || 24.7 || 24.3 || 24.2 || 25 || 25.1 || 25.05 ||
 * medium || 24.1 || 24.1 || 28.1 || 28 || 24.6 || 24.4 || 25.6 || 25.5 || 25.55 ||
 * fast || 24.4 || 24 || 24 || 23.8 || 23.5 || 23.3 || 23.96 || 23.7 || 23.83 ||

Summary: In conclusion, our hypthesis was right and wrong. It was right, because the temperature did go down. It was wrong,

because the temp only went down a few degrees, or a tenth of a degree.

Temp. Lab ( wet) (water)

Question: How will fanning affect the temp of a wet themometer?

H. We think that the temp of the thermometer will go down as it is fanned.

IV: Fan

DV:Temperature C: water amt, alcohol amt. ( this graph goes in the interval of 20 seconds)

Temp Lab (wet) (alcohol) average || overall average || Summary: the alcohol had given the affect that it was colder and it evaporated quicker, than the plain water, in which it had evaporated slower. Absolute Pressure Lab Question: How does he volume of air in a syringe get affected by pressure? Hypothesis: If the volume increases, the pressure decreases, if the volume decreases, the pressure increases. IV: Volume of the Air (mL cubed) DV: Pressure (Kpa) Constants:Syringe, trials
