Any flying object, whether it is aircraft, spacecraft, soccer ball or fly a kid, experience four aerodynamic forces of :. Lift, weight, thrust and drag
Plane uses a propeller or a jet engine to generate thrust. The wings create lift. The smooth, pencil-thin shape minimizes drag. And molecules that make up the plane qualities that weight.
Let’s find out what are all the parts for the planes. You need to get a cheap balsa wood airplane for this next part – check local drug store or toy store. I even find them in grocery stores for about $ 2.
Take Balsa wood plane and try to fly just on the body (no wings or fins). It flips all over the place. Try to fly just large wing (no). Heljarstökk!
Now slide the large wing in the body and fly (fewer somersaults, but still sickening to fly!).
Now add the horizontal stabilizer (lift) tail, and when you throw, add a slight curve so the plane “fish tails” in the air (like a car) … but did you notice that there are no more somersaults?
Add vertical tail (rudder) and see how it currently manages directly no matter how curve-throw
Sneaky Tip :. If you remove the metal clip on the nose in advance, you can add it last to really see what it is … notice where most of the weight is without clamping
Let’s do more things that show these ideas fly
Helicopters 😕 Cut out paper rectangle 5 with 2 inches. Cut lengthwise down the strip, stopping inches away. Tape this uncut inches to the tip end of a Popsicle stick. Fold “rabbit-ear” flaps down in opposite directions. Throw off the balcony and watch the whirl and Gyrate! (Optional: You can notch end popsicle sticks to make sling shots helicopter Make a quick slingshot launch of the loop a rubber band to another Popsicle stick end ..)
Butterfly Cups: Tape two Dixie paper cups together, bottom bottom. Chain together six rubber bands. Loop one end of the rubber band chain of thumb and hold your arm straight out horizontally, palm up. Drape the rest of the chain along the arm. Set glued butterfly cup free end (near the shoulder) and slowly wind the rubber bands around the middle part of the cup. When you wind the end, stop, chain stretching back to the elbow, make sure the rubber band comes from the underside of the cup and release. Cups should quickly turn and take the air, then gracefully down below the landing lights. Try to do one of four cups
Hot Air Balloons :. Shake out garbage bags to its maximum capacity. Ribbon (use way or masking tape) open end almost-closed … you still want a small hole the size of a hairdryer nozzle.
Use a hair dryer to blow the bag and heat the air inside (make sure you make the melt bag).
When the air is at its warmest, loosen your hold on the bag while turning off the hairdryer. It should float up into the air and stay there for a while. This experiment works best on cold mornings. The greater temperature difference between of air the bag is and the air around, the longer will float
Para Chutes :. Attach a piece of yarn or thin band to the four corners of the tissue. Attach a stick, a small wad of stones wrapped in another tissue, pine cone, etc. for central band. Practice dropping them from the balcony and see who falls slow that load
Ring Thing :. Cut the index card thirds lengthwise. Loop one strip in a circle and tape the ends together. Place two remaining panels together end-to-end and tape, then loop in a large circle and tape in place. Put a piece of tape over one end of the straw and gently ensure a round of table. Repeat on the other end with the remaining circle. Make sure that the two rings are concentric (you can see through both a telescope). Throw a little-end first
Free Form Machines: Make an obstacle course with some or all of the following different challenges
hits the target balloon (arm machines with opened paper clips)
-Go over and under pending length of the string
-Make through Hula Hoop postponed vertically or horizontally
-Carry gel bean passengers definitely over shark- infested Lakes (two tablets spread apart)
-Dangle large paper airplanes (from 11×17 “paper or two 8.5×11” adoption papers together to make a 11×17 “) from the air ‘Dogfight’ to earn points if you mean one
– Shoot through a basketball hoop, and dive into the cart.
