...Percent difference in mass of each egg after soaking in the sucrose solutions Experimental Question: If we change the amount of sucrose in each solution that the eggs will sit in, how will this affect the difference in the mass of the eggs? Hypothesis: If an egg is placed in a 4 M sucrose solution overnight, then that egg would lose a greater percentage of its mass than the eggs placed in any other solutions tested, because the solution it is in has a higher concentration of solute (sucrose) which makes the solution hypertonic so the water will diffuse out of the egg. Control: Distilled Water (0.0 M solution) Constants: How long the eggs are...

...The Effect of Calcium on Hatching Brine Shrimp Eggs science fair project will investigate how the addition of various amounts of calcium to brine shrimp eggs will affect their hatch rates. I was drawn to this area because I have an interest in how several outside factors can affect the nature of a process. My hypothesis for this lab is that the larger amount of calcium added into a petri dish will result with a faster hatching rate due to the extra nutrients. The independent variable of this lab is the concentrations of calcium, while the dependent variable is the brine shrimp eggs hatch rate. The constant is petri dish A that will have no calcium added. I plan on measuring this rate through observing the individual petri dishes every twelve hours under a magnifying glass and counting the number of eggs that hatch. The science of this lab can be traced back to the background...

...an experiment which involved putting an egg without a shell in three different substances. We put the first egg in water, the second egg in corn syrup and the third egg we wrapped in saran wrap and placed in an empty cup. We used an egg in place of a cell because they both have similar qualities, such as the cytoplasm being the inside of the egg and the nucleus being the yolk. Diffusion is the movement of cells from an area of higher concentration to an area of lower concentration. Osmosis is the movement of water molecules across a semi-permeable membrane. Diffusion and osmosis are important because they help with cellular respiration, which is how we stay alive. We conducted this experiment...

...Mealworm Response Lab Mealworms are the larvae of the Mealworm Beetle, also known as the Darkling Beetle. The Mealworm Beetle life cycle consists of four stages: the egg, the larvae, the pupa, and the adult. Mealworm beetle eggs are small elongated spheres, about the size of a dime. The eggs hatch anywhere from four to nineteen days after being laid. When the mealworm beetles hatch, mealworm larvae emerge. These larvae feed on plants and dead insects. As these larvae grow, they periodically molt and shed their exoskeleton. Mealworm larvae are high in protein and make good food for birds and reptiles. Mealworm beetles spend eight to ten weeks in their larval stage. After the larvae have completed their last larval molt, they transform into an...

Ronald Olson became vice-president of marketing Poultry Industry In the beginning, poultry and egg production was done in the family background. In the 1930’s, in order to improve the efficiency of production, farmers decided to use henhouses. In the 1950’s, there was a bigger concentration of the poultry industry with the use of cages. In 1974, there were 2.5 million of birds in U.S.A. California, North Carolina and Georgia accounted for 25% of the nation’s chickens, while 9 additional states accounted for an additional 36% of the chicken population. There were basically 3 sizes of firms: 1. Small Firms(lower than 10,000 birds)- Usually family operated. The birds would be housed in henhouses. The number of such farms has been declining at the rate of 25% per year 2. Medium Firms(10,000-50,000 birds)- These firms are professionally operated farm of...

...Farm factory This documentary awakens many feelings inside me. I am so concerned about this fact and to have learned and saw how it actually happens, I think that more than one could be saddened about it. Animals feed us, in fact it is their fundamental goal, the reason they are created. I believe we should be thankful and deliver some respect. They are inferior beings but they should not be cruelty treated. They do not have our rationality and cannot defend themselves against us. Besides the fact that they give their meat and derivatives from it, we humans abuse their generosity. They also have the right to live and die decently. I am not voting for becoming vegetarians all the way, but to change the industry for farm animals. Laws should be created in order to follow a certain procedure with a higher quality standard of living for these animals in the factory. Also, to support these farms caring for the lives of animals. In the documentary, we clearly can see that they have feelings and they also can feel the pain and desperation to learn that they are going to be killed. It also hurts us, those that care about them. I am extremely concerned about this issue, it makes me not eat meat anymore but that is not the point. In fact, I have always cared much about animals, sometimes even more than caring about a person. The way I see it’s that animals cannot defend themselves, and somehow humans have the ability to do that, to speak out, but animals do not. I have saved lives of...

...Hatched a Chiken Egg in an Incubator Can you remember the last time you were passionate to learn something new? Neither can I. But we have all been passionate to learn at some point in our childhood. To kids the world seems like a magical place, full of mysteries waiting to be discovered. I’m sure all of us can recall some pleasant memories experiencing with science as a child. In this essay I’m going to talk to you about an experiment I did in my childhood with an incubator. It was a joyful experience for me. The first important thing I needed to do in order to hatch chicken eggs was to find an incubator. That was the easy part since I could borrow one from my school. It wasn’t actually an incubator. it was a device that students in 5th grade had to make, and it worked like an incubator with a few differences. The device could only be used to maintain the temperature needed for the experiment. The rest I had to do by hand. It was plugged into electricity 24 hours a day, and it had a lamp inside it to make the area warm and light. Finding the incubator was pretty easy. Using it was a little harder. I had to find the right eggs, if I wanted to hatch them and turn them into chickens eventually. First I had to make sure they weren’t stored for more than 7 days. Old eggs weren’t going to turn into chickens. And I also had to make sure that they were stored in a cool humid area, and were not damaged, and didn’t have any holes or cracks. Size of the eggs was important...

...Europe due to its unique packaging. It is another egg containing a surprise - and therefore a member of the Kinder Sorpresa family - but it is decidedly more technological. It is made up of two plastic valves, half of which contains the food which you eat with the spoon provided while the other half contains the surprise. These two parts are joined and when opened make a noise that children love, a “clack” that heralds the surprise they will find inside. This extremely modern and amusing product was born of highly specific needs which in this case consisted in taking Kinder Sorpresa to those parts of the world where distance and climate might have hampered its distribution (chocolate shell, packaged in an aluminium film cannot be sold in hot and humid countries). Instead, Kinder Joy withstands humidity and high temperatures and is a hyper-protected and hygienic product suitable for emerging markets such as Africa, South America, India, or places where the climate is not conducive to chocolate. Here the packaging is technically highly advanced and the content integrates perfectly with its packaging… Exceptional research was carried out on barrier, multi-layer and thermoformed materials. Our objective was to protect the product totally. You can easily imagine the difference in terms of costs between Kinder joy and the egg wrapped in aluminium. The format is identical but they are worlds apart. The little surprises contained in the eggs have reached an incredible level of sophistication...

...a single hen as a sign of his gratitude for my contribution to his farm. Since then, chicken became my pet and rearing poultry became my hobby. This goal was further motivated by my agriculture lessons in class were I learnt best practices for rearing poultry. As at now, I have over 5000 chicken, more than half are layers and the rest are broilers. Besides chicken, I rear ducks, geese and turkeys, all of which are profitable. Chicken farming has become my livelihood and I do not intend to look for formal jobs. Benefits of keeping poultry on your homestead 1. Egg production If you are a non-vegetarian as I am, then you definitely consume eggs unless they give you some abdominal discomfort. Keeping poultry on your homestead, specifically layers gives you a chance to enjoy eggs without limits. Eggs have numerous healthy benefits in your body because they contain vital mineral elements. I keep White Leghorns for egg production and their yield has never discouraged. 2. Meat production Poultry meat is irresistible. Poultry meat is my favorite and you know what, keeping poultry on the homestead ensures that you enjoy fresh meat, which is free from chemicals additives found in their feeds and antibiotics. Meat poultry matures fast provided you give them the required feeds. To be specific, it takes a broiler two months to be mature...
