Physics 11 Egg Drop: Writeup

1.Discuss the structure of the plasma membrane and explain the process of active and passive transport through the membrane.

In the broken eggs problem my task is to find out how many eggs she had when she hits a pothole and fell. Every egg broke and the only information she knew was the following:

The egg drop project is designed to use what we have learned in science and apply it to a more hands on project. The goal is to keep a raw egg from cracking or breaking after a 3 meter drop. There are quite a few constraints that go along with this project such as materials, time management, and deadlines. The only materials allowed to be used on this project are; 10 straws, 2 sheets of paper, 30 cm of tape, 5 Kleenexes, 1 sandwich sized plastic bag, 25 cotton balls, and 50 cm of string. The plastic bag must be used to contain the egg in case of breakage and the final product must fit into a 15 cm cube. All of the building work must be done in class.

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

In the lab of “The Falling Eggs and Automotive Lab”, we had to design a protective device able to hold the egg and allowing it survive from the impact of hitting the ground from the top of the staircase. We did this lab to investigate newton’s Laws and prove how they work. In the lab, we have to observe the forces that act on the egg and evaluate the way they work. We do this lab with an egg to relate to a real life collision with a car. The egg is essentially the person and the device that the egg is in is the Airbag. We use our knowledge about airbags and apply that to this lab in order to make the egg survive and not crack.

Crumple zones are designed to absorb the energy from the impact during a traffic collision by controlled deformation. This energy is much greater than is commonly realized. A 2,000 kg (4,409 lb) car travelling at 60 km/h (37 mph) (16.7 m/s), before crashing into a thick concrete wall, is subject to the same impact force as a front-down drop from a height of 14.2 m (47 ft) crashing on to a solid concrete surface. Increasing that speed by 50% to 90 km/h (56 mph) (25 m/s) compares to a fall from 32 m (105 ft) - an increase of 125%. This is because the stored kinetic energy (E) is given by E = (1/2) mass × speed squared. It increases by the square of the impact velocity.

The purpose behind the egg drop project is for students to understand the concept of momentum, collision, impulse and force. To do this, they will create a protective carrier that will surround the egg. The egg will then be dropped from a certain height. The device that is created should weigh enough to increase the time of impact, therefore decreasing the force of impact on the egg so it doesn’t crack.

In light of our final exam, the chuck a duck project, we are to learn about projectiles, trajectory, and the factors that affect these things.

The lab we did required multiple similar steps, with small variations between them. To begin, we weighed out separate amounts of baking soda (NaHCO3) for separate test tubes. We had 6 test tubes labeled 1 through 6. Each test tube held 0.180g, 0.350g, 0.520g, 0.700g, 1.000g, and 1.700 g of baking soda respectfully. We also used six balloons to each hold a certain amount of vinegar (CH3COOH). Each balloon held 10 ml of vinegar. We used the balloons as a way to get the vinegar into the test tubes by fixing the balloon over the mouth of the test tube, being careful not to let the two materials inside mix. This was the beginning of our lab.Our hypothesis was that balloon number 5 would be the largest balloon due to the nearly even ratio of baking soda to vinegar, we were proven wrong through the experiment. Balloons 1 through 3 had an excess of vinegar, which means that all baking soda was dissolved. Balloons 4,5 and 6 had excess baking soda, which means that the vinegar was unable to dissolve all the baking soda. Balloon 6 was the largest balloon.

We had to do an egg drop so when it is dropped from 20 ft it wouldn’t crack.. But I really didn’t have any background knowledge on egg drops because I never did one. But I did know that by putting a plate on the bottom it would make it float down and not fall. So when it was dropped from 20ft it wouldn’t crack.

Place 100 ml of distilled water in a 250-ml (or 400-ml) beaker. Add 1.26g of oxalic acid dihydrate (H2C2O4.2H2O) and 1 ml of concentrated ammonia. Stir the mixture until the solid has dissolved completely.

Have you ever heard of drop the egg challenge? Well, I’m here to tell you about my drop the egg challenge. You have to drop the egg from a distance in the air, but the egg cannot crack. Yes, it is possible. Here’s the supplies my partner and I used. We had a bowl, rocks, cardboard, four paper towel rolls, gorilla tape, hot glue gun, and of course an EGG! First we placed the rocks in the bowl, then glued a square foot piece of cardboard on top of the bowl, next we glued/taped the paper towel rolls (on top of the cardboard glued to the bowl), after we cut a small circle in a small square piece of cardboard (so the egg can fit in it), therefor we glued the egg in the circle and we cut a half of a bottle and put it

"Bluebeard's Egg" is Margaret Atwood's short fairy tale retelling of the Bluebeard tales. Atwood is a writer who reveals an awareness of women's identity. In her fairy tale, she introduces the theme of heroine's identity struggling in her relationships between her and Ed, Sally's husband. Sally is a woman who attends a college for taking night courses and to keep her busy, and she thinks her husband, Ed is dull and stupid. However, Ed is always in the center of her life, and so she is described to be insecure in her marriage. Later, in the main part of the story, Sally's identity becomes more uncertain after she witnessed an affair between Ed and her best friend, Marylynn. Unlike she used to think Ed as idiotic, the story seems to represent

Four eggs that were previously soaked in vinegar were placed into four beakers with different levels of a glucose solution. The four beakers were filled with distilled water, 0.5M glucose, 1.5M glucose and 2.0M glucose. After the eggs were placed in the solutions, they were left for 60 minutes but weighed every 15 minutes to record whether there was an increase or a decrease in mass. The various masses were recorded as well as the percent change in mass. These were then recorded as line graphs. From this it was able to be determined if the egg had been in a hypotonic, hypertonic or isotonic solution, thus being able to determine if osmosis had occurred.

The main aim was to see if scapula-stabilising exercises could influence the velocity and accuracy of the tennis serve. This experiment focused on recreational tennis players due to limited research in this area of tennis.
