In this egg drop project, a container was built to house one egg and was then dropped at various heights. The purpose of this lab was to find how impact time affected the force with which an object, the egg container, hits another surface as the momentum moves to zero. Our hypothesis states that if the impact time is stretched longer then the force exerted on the egg would decrease, making the egg less likely to break. The independent variables for the egg drop project was the height at each drop; the dependent variables were impact time and survival of the egg. The controls were mass, design of the container, and the egg.
Egg Drop Activity was one of my favorite experience that I was excited to explore in this class. while working on this activity, I had a fun time to cooperate with my classmate, Briana to try different ways to protect the egg. However, I was struggling to layering materials provided to protect the egg because I needed to hold the egg carefully. While exploring with this activity, I learned that from this experience that everybody had different techniques, and they also used diverse materials to protect the egg. Personally, I took a long time to think critically and creatively to make the protection for the egg. I also learned through play that I needed to add more bubble wraps and tissue papers probably to protect the egg. In addition, this activity also fostered my communication skills because I used languages to discuss and design the protection for the egg from breaking when it hit the ground. I learned from my peers that she was very patient to cover the egg by using the bubble wrap, tape, and tissue papers.
The Pop Rocks have a very small amount of carbon dioxide in them. When the Pop Rocks are in your mouth they dissolve and the carbon dioxide is released making the pieces of candy explode in your mouth. When the Pop Rocks come in contact with the soda, the gas in the Pop Rocks escape after disolving and the carbon dioxide escapes from the liquid into the balloon. When this happens it causes the gas to make the balloon expand bigger and bigger until the air can escape.
For each of the condition, about 35 milkweed bug eggs will be placed in clear container (5”x7”x4”) with a fine netting between the lid of the container and the container walls. The netting prevents the milkweed bugs from escaping while allowing for air to come in. Each container
Starting with the food chain in Chesapeake bay, the plants and algae play the basis role in food chain. They make their own food by sunlight. These plants and algae are bay grass and free floating algae. The plants and algae not only feeds all other organisms in the water but also gives homes and shelter for other organisms. Frogs lay their eggs on the bay grass, giving the tadpoles a home. Fish use the grass for shelter, to hide and protect themselves. Next in the food chain are copepods, which are very small organisms in the animal community, which are mostly referred to as zooplankton. These zooplankton consume the algae and bay grass. The next link in the food chain are anchovies. Anchovies consume the zooplankton. The anchovies are then eaten by tertiary consumers, which are the bigger fish. The last link in the food chain are humans. We then eat the bigger fish (Food Web).
The egg we experimented on went through many dramatic changes. In its original state, the circumference was 14 cm, and it was 66.8 grams in mass. However, it was much larger after it was put in the vinegar for 48 hours, the circumference was 17 cm, and the mass was 89.1 grams. This occurred because of osmosis. Since the vinegar had more water molecules than the egg, it was transferring the molecules to the egg to create equilibrium; therefore, the egg became larger.
As the marble slides down the first drop it will lose much of its potential energy corresponding to the loss of height. The marble subsequently gains kinetic energy – kinetic energy is contingent to the mass and the velocity of an object. The marble speeds up as it loses height, consequently, their potential energy is transformed into kinetic energy. Newton’s Second Law states that an object’s net external force is equal to its mass times its acceleration; simply, the acceleration is proportional to the force applied and also the mass of the object.
When using a hypertonic and hypotonic solutions they can be shown in many different ways one way we showed this is putting an egg in corn syrup. The purpose of this lab is that students can observe and predict what is happening to an egg when you put it in hypertonic and hypotonic environments. The environments we put the egg in are vinegar, corn syrup, and water with food coloring. Using these materials we learned about osmosis, hypertonic environments, hypotonic environments, and passive transport. The purpose of this lab was to learn and get a better understanding of what is happening in the movement of molecules. If we put an egg into different environments then we will observe osmosis, passive transport, hypertonic environments, and hypotonic environments because the egg has a permeable plasma membrane and we will observe the effects of osmosis.
DESIGN PSOW Ajit Rajendran 13H To Determine the Time Taken for a muffin paper cup to reach the ground, while Changing the Height of each experiment Introduction: In this experiment the aim is to determine the time taken for an empty muffin paper cup to reach the ground, by changing the height the empty cup is dropped from. Both variable mentioned are going to measured (height and time taken), when conducting the experiment. In order to have a fair experiment, certain factors will be kept the same throughout the experiment: the same paper cup will be used, the dimensions of the paper cup will be constant (where external factors do not affect the shape), the method in which the paper cup will be dropped.
These factors include the size and shape of the object. For example, the shape and size of paper of a rock differs from that of paper. But paper, because of it shape and size, would float down slower with more air resistance than the rock which has less air resistance. For example, in a well known article on the fall of an object, states, “More massive objects will only fall faster if there is an appreciable amount of air resistance present” (The Big Misconception 1). This shows the fall of an object does not care about mass but size and shape.
The Head of the Rain God Tlaloc is a Pre-Colombian statue that appears to be massive and could possibly weigh almost a thousand pounds due to its size and material composition. The statue appears to be made up of ceramic and stucco that was once beautifully painted with vibrant colors. Due to the monument being very large, one could infer that it would be placed atop of a large structure such as a pyramid with a temple on top. The scale of the design and the symbolism gathered from the various features aid in adding vibrancy and meaning to the sculpture.
I taped the back of two plates together which is a wheel of the car, and used sticks to connect all four wheels, then I putted the balloon to the car and start our first trying. Surprisingly, the car didn’t move at all! Why, it is not as well as I thought. I failed in the first trying. I told myself, “One fail will not prove anything, I can do it”.
Get an entire package of Pop Rocks into a balloon. You might be able to pour the candies into the balloon 's mouth, but you could use a small funnel. Place the narrow end of the funnel into the mouth of the balloon and empty the Pop Rocks packet into the funnel. Make sure all the candies are in the balloon by giving the funnel a few firm taps. Place the balloon over the mouth of a bottle of soda.
