Needle through a Balloon

Pre-Lab Preparations:

Purpose: The purpose of this experiment is to see if the balloon pops when pierced with a wooden skewer or a sharp pin.

Hypothesis: If we lubricate the skewer with petroleum jelly, then it should go through the balloon without popping.

Hypothesis for the 2nd part of the Lab: If we cover the side of the balloon with cellophane tape, then it will not pop when pierced with the pin.

Materials:
• Balloons
• Long wooden skewer
• Petroleum jelly
• A sharp pin
• Cellophane tape
• A pencil
• Paper

Pre-Lab Questions:
1. The balloon is being tested and analyzed
2. We are using sight and touch
3. Independent= petroleum jelly
Dependent= the balloon
4. Controls= Petroleum jelly
Constant= the cellophane tape and a sharp pin

Pre-Lab Questions for 2nd part of Lab:
1. The balloon is being tested and analyzed
2. We used sight as our scientific skills
3. Independent: the pin
Dependent: the balloon
4. Control(s)= cellophane tape
Constant= the air in the balloon
Procedures and Observation:

Procedures: Observations:
1. Blew up the balloon Nothing happened
2. Put petroleum jelly all over the wooden skewer The wooden skewer is completely covered with petroleum jelly. The petroleum jelly feels greasy
3. Put the skewer gently into the balloon It took a while for the skewer to go inside the balloon
4. Pushed on the skewer a little harder The skewer finally went inside the balloon and the petroleum jelly was pushed to the end of the skewer. The entrance point and end point of the balloon is darker than the inside of the balloon.

Procedure for 2nd part of lab:
1. Blew up the balloon Nothing happened
2. Put cellophane tape on the side of the balloon and press down hard Nothing happened
3. Poked the needle through the side of the balloon Needle went right through the tape into the balloon and did not pop
4. After

    NASA Egg Drop Competition

    Procedure: The procedure to make the device was as simple as cutting two bottles in half so that you may then stretch the balloon over the opening that you have created. This is where the egg will rest during the fall. Measuring the device we placed it on a scale to see exactly what its weight was, which turned out to be 76.5Kg. The dimensions of the structure were measured with a ruler using the centimeter side. The dimensions came out to be 9cm x 9cm x 24.5cm. Just below the maximum height. Testing the fall, we took the egg and the structure over to the rotunda to drop it from about 5.3 meters. You would then be judged on how or if the egg survives the fall and given a score that fits well.…

    Egg Drop Project Essay

    For this project, I made a capsule for an egg that is to be dropped from about twenty feet. This capsule that I made was not what I was thinking at first but when I started to build it, I saw that this capsule would hold better than the one that I was thinking which was a triangular capsule with the egg in the middle but I saw later one that the egg would break if it hit one of the flat sides. The capsule is a cube that is made out of the tongue depressors and I used most of the yarn for the big cage and I used the Elmer’s glue to glue the tongue depressors together. I used pieces of the paper clips to hold the popsicle sticks together with the tongue depressors and some more glue. I then made the center, which was made by two popsicle sticks that I had which formed into a triangle and I made a little railing around it with the paper clips. I then put the cotton puffs inside the triangle that was formed with the two popsicle sticks and it is used to cushion the egg while it’s falling so when it hits the floor, then it wouldn’t receive all the damage if the cage were to break and the small egg holder were to fall out of the capsule or if it were to hit the floor straight. I used the pipe cleaners to hole the egg inside the egg holder so that it doesn’t fall out of it and break. I used some glue to glue the cotton puffs to the railing that was made for the egg holder and to the two popsicle sticks.…

    Lab for Chemistry

    The purpose of the Density Lab was to determine the identity of four unknown solids and two unknown liquids by calculating their densities and comparing them to a density chart, taking into account error analysis and finally classifying the substances. In order to calculate this density, we first found the mass of the container that was to be holding the substances. We then found the volume of the substance, and lastly determined the mass of the container and substance. We subtracted (Container + Substance) – Container to find the mass of simply the substance. In order to distinguish density, we took the final mass divided by the volume, and identified the substances based on Density Charts we found online. Originally we hypothesized that we would be able to identify these substances based on the densities we calculated, yet this proved to be harder than it seemed, however our hypothesis was correct. We now could concluded the densities and identification. The density of Unknown Liquid 1 was 1.26 which was found to be Colorless Glycerin (also density of 1.26) and Unknown Liquid 2 was 0.88 or Rubbing Alcohol (colorless). Unknown Solid 1 has a density of 7.20 or Iron, Solid 2 is 2.59 and Aluminum, Solid 3 is 5.47 and Tin, while Solid 4 has a density of 9.81and Nickel? We…

    Obviously I built this device with some prior knowledge to physics and how to make this device successful. I have learned several equations about force, work, power, height, speed, velocity and a lot more. So with force, f=ma, then I can easily discern what the force of the egg will be. Also, since I know all of these things, than I can figure out all of the physics with just the equations. Also I learned, with these things, that if the force of the egg doesn’t have something to fall into, like cotton or balloons, then it will break, because the force needs to be shared or it takes over the egg. With that, I understood a basis of how the device should be.…

    The Red Balloon Essay

    When the boy leaves the balloon outside to buy from a bakery, the schoolboys steal the balloon. And now that they finally have the object of their desires, the boys use slingshots to hurl stones at it. Eventually, the boy manages to rescue the balloon, but the reunion is short-lived, as the schoolboys chase him around town to steal the balloon again. In this encounter, there is clear hostility in the schoolboys' intentions as they physically hold the boy down and continue to pelt the balloon with rocks. And it all culminates when one boy steps on the balloon, popping it. This action fully captures the idea that "if i can't have it, no one can." After being refused the balloon on multiple occasions now, the boys began to lose hope that they would ever get the balloon. However, the lust for the balloon was still there, and the combination of that wanting and rejection quickly evolved into a certain spite for the balloon. Malice in their hearts now, the schoolboys set out to break the balloon for some sense of vengeance, satisfaction, and perhaps…
