Paper Airplane Lab

1. __State the problem:__ Does the shape of the plane affect the distance it flies?

2. __Form a hypothesis:__ We think planes go farther with wing flaps than without.

3. __Test the Hypothesis:__ To test it out, We would make 2 paper airplanes, one with wing flaps and one without, and throw them three times from the same starting point and see which one goes farther.

4. __Analyze the results:__ We would make a table showing the distance of the planes after each throw. We would average the results to get our answer.

5. __Draw Conclusions:__ We would state the hypothesis and whether it was right or wrong.

Question: Does wingspan effect the flight length of the paper airplane, if so how?

Hypothesis:

It will effect the flight length of the paper airplane, the wider the wingspan, the farther it will go

Independent Variable:

Wingspan

Dependent Variable:

Flight length of the paper airplane

Constants:

Mass, starting point, Person throwing it, weight

Procedure Diagram:

We researched different designs on this website but created our own versions of the planes on the website.

Mass and Volume Lab
Does the mass of an object affect its volume? Hypothesis: I think the mass of an object doesn't affect its volume.

Dependant Variable: volume(cm)

 * **//Object//** || **//Mass(g)//** || **//Volume(cm)//** ||
 * **//Aluminum Prism//** || **22.9** || **8** ||
 * **//Nylon Prism//** || **23.6** || **20** ||
 * **//Screw//** || **10.5** || **9** ||
 * **//Nylon Spacer//** || **6.9** || **5** ||
 * **//Copper Cylinder//** || **54.9** || **7** ||



__Hypothesis:__ I think the mass of clay does affect it's volume. Since he clay has the same density and is made out of the same materials it will have a large volume with a large mass.

 * Length || Mass(g) || Volume(cm) ||
 * 1.25 || 10.4 || 6 ||
 * 2.5 || 14.9 || 9 ||
 * 3.75 || 25.4 || 15 ||
 * 5 || 37 || 22 ||



====**__Summary~__** Our group's hypothsis was correct. The mass of the clay does affect its' volume. We tested the clay at 5cm, 3.75cm, 2.5cm, and 1.25cm. The more the mass[of the clay], the more the volume will be.====

Clay is not a common boat-building material because clay is more dense than water. We should shape it wide and bowl-shaped just like a real boat. When a boat is put in the water, it displaces the water. a force pushes up on the boat making it float. The density of the boat must be less than that of the water displaced in order to float. []

Question: Does the shape of the boat affect if it sinks or floats?

Dependant Variable: Bouyency

Independant Variable: Shape of the Boat Hypothesis: We think the wide bowl-shaped boat will float, and the square and triangular boats will sink.

Constants: Material of clay, amount of water in beaker, amount of clay used. Ice Cube Lab Question: Does a Physical Change affect the mass? <span style="background-color: transparent; color: #000000; display: block; text-align: left; text-decoration: none;">Hypothesis:We think the mass of the ice will be greater than the mass of the water. <span style="background-color: transparent; color: #000000; display: block; text-align: left; text-decoration: none;">Constants: amount of water, amount of ice, weight of zip lock bag alone

Fanning Lab
Question: Will fanning a thermometer change its temperature?

Hypothesis: The fan will affect the temperature of the thermometer. The thermometers temp. will drop.

Independant: speed of fan, size of fan. Dependant: temperature of thermometer. Constants: fan, thermometer + holder, computer

Summary: The hypothesis was incorrect. The fan did not affect the temperature of the thermometer. The temperature stayed constant at 24.1 degrees Celsius.
 * Fan Speed || Temperature(C) ||
 * None || 24.1 ||
 * Slow || 24.1 ||
 * Medium || 24.1 ||
 * Fast || 24.1 ||

Wet Fan Lab
Question: How will fanning affect the temperature of a thermometer wettened by water? Hypothesis: I think the temperature will go down.

Independant: Fan speed Dependant: Temp. of thermometer Constants: fan, thermometer + holder, computer


 * Fan Speed || Temperature(C) ||
 * None || 16.6 ||
 * Slow || 15.7 ||
 * Medium || 16.3 ||
 * Fast || 15.8 ||

Summary: The hypothesis was correct. The temperature did drop when the fan speed increased.

Wet Fan Lab Part 2 p1g3
Question: How will fanning affect the temperature of a thermometer wettened by alcohol? Hypothesis: The temp. will drop.

Independant: speed of fan Dependant: temp. of thermometer Constants: fan, thermometer + holder, computer, fan size


 * Fan Speed || Temperature ||
 * None || 13.2 ||
 * Slow || 11.2 ||
 * Medium || 10.7 ||
 * Fast || 11.1 ||
