Notes on Paper airplanes:

10.Your plane should weigh less if you want it to glide.
 * 1) If an object is not moving, it will not start moving by itself. If an object is moving, it will not stop or change direction unless something pushes it.
 * 2) Objects will move farther and faster when they are pushed harder.
 * 3) When an object is pushed in one direction, there is always a resistance of the same size in the opposite direction.
 * 4) Big wings with the back of the wing bent, for lift.
 * 5) if one side of the plane is bigger the plane will fly in.
 * 6) []
 * 7) airplanes wing drag is decreased by increasing the wing span.
 * 8) you want the tip of the wings to be the highest part of the plane.
 * 9) your plane must be aerodynamic

Question: Do the flaps on the end of the wings effect the flight time and patterns of the planes? Hypothesis: The plane with flaps with go farther, but fly slower. Constant: paper used in the airplane & throwing force. Independent: flaps & wing size Dependant:Time Pictures of planes- Data Table- **3** || **Average Time** || Summary of Paper Airplane Lab: The plane with the biggest flaps flew the longest. The plane with small flaps flew for the shortest time. The plane with no flaps flew longer than the plane with small flaps, but shorter than the plane with big flaps.
 * **P lane Experiment ** || **Trial 1** || **Trial 2** || **Trial**
 * **Plane with no flaps** || 3.41 sec. || .91 sec. || 2.00 sec || 2.11 sec ||
 * **Plane with small flaps** || 1.30 sec. || .94 sec. || 2.00 sec || 1.41 sec ||
 * **Plane with big flaps** || 3.00 sec. || 4.41 sec || 1.84 sec || 3.08 sec ||

Conclusion of Paper Airplane Lab: The bigger the flaps the longer a plane will fly in the air. We think that this will happen because the flaps give lift to the plane and it also helps the plane glide in the air.

= = =Notes on Clay=

Question: Does the mass of the clay affect it's volume? Independent Variable: Mass(g) Dependent Variable: Volume(cubic cm) Hypothesis: The mass of the clay will affect it's volume.

Conclusion- The mass of clay affects the volume because the more mass the more volume. Summary-Mass does affect volume and both affect density.

=Float or Sink? A bouancy lab:= This is the website we modified to fit our experiment. @http://www.newton.dep.anl.gov/askasci/phy00/phy00615.htm [] - we don't trust all of the info but the pictures are higher level thinking Bouancy Lab: Question: Will the length of the boat effect it's bouancy? Hypothesis: The longer the boat is the better it will float. Independent variable: The length of the clay. Dependent variable: Will the clay float? Constant: The water used in the pan & the amount of clay used. The shape of the boats. Procedure Diamgram- We measured the length of the bottom of the clay boats to see if it affected how the boats floated in the pan of water. Data Table- Scatter plot-
 * number of boat || length of the bottom of the boat || float || sink ||
 * 1 || 5.5cm+_ .5cm || * ||  ||
 * 2 || 6cm+_ .5cm || * ||  ||
 * 3 || 2.5cm +_ .5cm || * ||  ||
 * 4 || 4.7cm+_ .5cm || * ||  ||
 * 5 || 3.4cm +_ .5cm || * ||  ||
 * 6 || 7.5cm+_ .5cm || * ||  ||
 * 7 || 9cm+_ .5cm || * ||  ||
 * 8 || 10cm+_ .5cm ||  || * ||
 * 9 || 7cm+_ .5cm ||  || * ||

Conclusion- The length of the bottom of the clay doesn't affect its bouyancy.

Summary-We changed the lengths of the bottom of our boats and debated wether it changed the bouyancy of our boats.

How to further the experiment-To further the experiment we could see if different types of clays affect bouyancy and we could see what does affect clay bouyancy.

What we learned-Our lab on bouyancy was great information to have,but our experiment still leaves our group with questions.

Question- Will a Chemical change affect the mass of the tablet? Hypothesis- The mass will stay the same. Independent Variable- Tablet (first dry then in water) Dependent Variable- Mass (g) Constant- Water and the Tablet Conclusion- The mass stayed the same even after the lab. Summary- We tried the mass of everything before and after the chemical change. The mass stayed the same. Our hypothesis was right! Question: How will the mass of ice compare to the mass after melting? Independent Variable:state of water Dependent Variable: mass Constant: the cup and balance Hypothesis:The mass will expand of the ice when melted. Conclusion-The water had a greater mass then the ice by.2g Summary-Water has a larger mass then ice. This is because there are more molecules spread out. This was shown by the .2gram difference.
 * Mass before Tablet || 41.6 grams +_ .05g ||
 * Mass after Tablet was added to water || 41.6 grams +_ .05g ||
 * Item || Mass ||
 * Mass of cup || 3g+_.05g ||
 * Mass of cup with ice || 14.8g+_.05g ||
 * Mass of cup with water || 15g+_.05g ||
 * ice mass || 11.8g+_ .05g ||
 * water mass || 12g+_.05g ||

= **Temperature Lab** = **Question- Will fanning a thermometer have an effect on the temperature?** **Hypothesis-The more the time you fan= less temperature expressed in degrees celcius.** **Independent variable-time** **Dependent variable-Temperature** Room Temp. 23.7 30 Seconds- 23.6 45 Seconds- 23.5 1 Fan. 60 Seconds- 23.5

Room Temp. 23.8 30 Seconds- 23.7 45 Seconds- 23.8 4 Fans. 60 Seconds- 23.9

Inference- The fans directed hot air towards the thermometer. Summary- The longer and more fans you use the higher the temperature.

secret liquid-
30 seconds- 12.1 45 seconds-12.4 60 seconds- 12.6 Room Temperature: 23.0 Conclusion: In this lab we found out that fanning a thermometer will not cool it down, because your just putting more hot air on it so it's remaining the same temperature. The alchol cooled the temperature down faster because it was already cool, and wet, so the temperature dropped more fast, but once the thermometer was dry the temperature rose again.
