...Science Project: Air Pressure (Egg in a Bottle) Introduction Atmospheric pressure is the force that acts on any object by the weight of tiny air molecules. Molecules in the air are invisible but they still have weight and they occupy space. Air Pressure changes with the change in the altitude. As the altitude increases the Air Pressure decreases and the altitude decreases Air Pressure increases. At an higher altitudes we have to breathe more often than at the sea level. If you are on Mt Evans then your ears pop to maintain the pressure. This happens because we have to maintain the outside and inside pressure. Our weather patterns change because of the air pressure. Figure – 1 – Shows the air pressure based on the altitude Figure – 2 – Graph shows Pressure vs Altitude Objective There are various experiments that can be conducted to show Air Pressue. Let us do an Egg in a bottle experiment to show Air Pressure. Doing this experiment we will develop the hypothesis on the effects of air pressure on the egg and how it squeezes it into the bottle. Experiment: Egg in a bottle Things or items required to perform egg in a bottle: 1. Eggs 2. Saucepan and stove to boil the eggs. 3. Wide-mouth bottle and bottle mouth should be smaller than the boiled egg. 4. Vegetable oil. 5. Matches 6.

...Introduction: Our challenge was to create a water bottle rocket, using 2-liter soda bottles, that will fly on demand to at least an altitude of 100 feet (30 meters) and land safely so that the raw egg aboard remains unbroken. Some specifications that our rocket needed to meet were to have a nose cone, 3-4 fins, and a crash proof container. Our rocket was required to be completely finished by the launch date, which caused us to rush through some parts of the construction process. One constraint that we had to deal with the entire time building was having no formal instructions to follow.We found this complicating because no one in our group had a lot of background knowledge nor experience about this subject matter before. Another constraint...

...Eating this delicious ice cream is much more satisfying than just drinking beer straight out of the bottle and would taste absolutely amazing sandwiched between two cookies or served on top of chocolaty brownies. For the ultimate ice cream, try sprinkling bacon bits on the top or covering the ice cream with decadent chocolate shell, yuuum! Step 1: Gather Ingredients Ingredients • 5 egg yolks • 12 oz of beer (one bottle) • 1 cup heavy whipping cream • 1 cup milk • about 1/4 cup sugar • a pinch of salt (optional) • a splash of pure vanilla extract(optional) For this recipe you will need one bottle of beer. I asked Bricobart himself and he suggests using a dark beer because the end result will be sweeter. You should use a malty beer versus a hoppy beer because the hops in the beer will turn bitter when cooked whereas malty beers become sweet. Think of a malt shake or Whopper malt candies, they're all very saccharine. I highly recommend asking an employee what beers that they recommend when shopping. I went to my local Whole Foods and picked up this Vanilla Porter that the employee recommended to me because he said it was very sweet and is great for desserts. Since all beers are different, you might need more than 1/4 cup of sugar. I would start off with 1/4 cup and then add more as needed. Same is for vanilla and salt. Vanilla and salt can definitely enhance the flavors of the ice cream but sometimes they aren't necessary. I didn't need any vanilla extract...

...four and you eat only farm fresh eggs? Number of chickens needed. If we are a family of four and consume an average of 10 dozen eggs per month, means that we will need our chickens to produce 120 eggs per month. Eggs needed monthly: A dozen = 12 eggs. So, 12 eggs times 10 dozen = 120 eggs. Eggs needed per week: We will need to find the number of eggs we consume per week. 120 eggs divided by four weeks in a month, gives us the total of eggs needed per week. 120 ÷ 4 = 30 eggs needed per week (Almost 3 dozen eggs per week; more specifically 2 ½ dozen eggs). After doing the calculations my partner and I discovered that we were going to need six chickens; five hens and one rooster. The breed of the chickens we decided upon are the Rhode Island Red hens. We decided on the Rhode Island Reds because they are noted for their brown and delicious eggs. They can end up producing up to 200 eggs a year and a healthier one can lay even more. Healthy hens lay up to 6-7 eggs per week depending on their care and treatment. Additionally, Rhode Island Red hens lay many more eggs than an average hen if provided with plenty of quality feed. Looking at the information we have gathered we will need: 30 eggs per week, thus 5 hens will be sufficient to cover that quantity. 7 eggs times 5 hens will give us the amount of eggs that we are going to have per week. Thus 7 ×5 = 35 eggs per week. And 4 weeks (one month) × 35 eggs will give us 140 eggs per month. This means that our...

These things are can be but are not limited to folate and folic acid, vitamin D, protein, and Iron. A few ways you can obtain these are through peanut butter, milk, eggs, poultry, meat, and cereal. There are things that could happen to your child if you do not watch what you eat as for as disease and health concerns in general. A few of those concerns could be abnormal brain development, higher risk of diabetes, obesity, heart problems and possible lower IQ. There are always things that can be eaten that are good for you and things that are bad for you. You always want to stay toward the good side of food but if for some reason you were to have to eat bad food you can eat in small quantities. Some of the foods you can eat that are good for you are carrots, eggs, brown rice, and chicken. Some things that you should not eat on a daily basis are overly sweet foods, sushi, or undercooked or raw meats. When I ask people how they prefer to feed their baby, if it is with breast milk or if it is with formula. I also looked up the pros and cons of each to see when I have a baby what I would prefer to do.

...SIMPLE SCIENCE EXPERIMENTS HANS JURGEN PRESS 1. Astronomy Image of the Sun Place a pair of binoculars in an open window in the direct path of the sun’s rays. Stand a mirror in front of one eyepiece so that it throws an image of the sun on to the opposite wall of the room. Adjust the mirror until the image is sharp, and darken the room. You would risk damaging your eyes if you looked directly at the sun through binoculars, but you can view the bright disc on the wall as large and clear as in the movies. Clouds and birds passing over can also be distinguished and. if the binoculars are good even sunspots. These are a few hot areas on the glowing sphere, some so big that many terrestrial globes could fit into them. Because of the earth’s rotation, the sun’s image moves quite quickly across the wall. Do not forget to re-align the binoculars from time to time onto the sun. The moon and stars cannot be observed in this way because the light coming from them is too weak. 2. Sun clock Place a flowerpot with a long stick fixed into the hole at the bottom in a spot, which is sunny, all day. The stick’s shadow moves along the rim of the pot as the sun moves. Each hour by the clock mark the position of the shadow on the pot. If the sun is shining, you can read off the time. Because of the rotation of the earth the sun apparently passes over us in a semi-circle. In the morning and evening its shadow strikes the pot superficially, while; it midday, around 12 o’clock...

The Resin Identification Codes assigns these resins with a number from 1 to 6, which are polyethylene terephthalate (PETE); high density polyethylene (HDPE); polyvinyl chloride (PVC or vinyl); low density polyethylene (LDPE); polypropylene (PP); or polystyrene (PS). The coding system also includes a seventh code which is labeled as "other." The principal roles of coding system for these resins are to provide a consistent national system to help consumers and manufacturers efficiently identify and sort plastics for recycling. The coding system is also enable individuals to maintain and perform quality control before recycling, which help to make sure the recycled plastic is as homogenous as possible. Hence, all...

...The problem addressed is how to drop an egg from approximately 18’ and enable the egg to survive the impact unscathed. There are many simple solutions available for purchase on the open market, but one of the constraints placed on this project is materials should be recycled or repurposed and not obtained from a retail store. The mission at hand is to obtain recycled materials, design a solution to the problem out of those materials, test the design and modify as necessary to improve the outcome to ensure the eggs safe landing, document the finding and lessoned learned. The materials available were obtained from a neighbors Radio Controlled (RC) Hoby Shop. Usually, there are more exotic materials available, such as old RC tires, or plastic bodies, servos, and motors. This week all that was available was empty aluminum soda containers, glass bottles, cardboard, and steel wool. I examined several manufacturing ideas which involved cutting the aluminum soda containers into strips of aluminum to be reassembled into a new shape. Ultimately this was too time-consuming and there is a safety factor due to the nature of the sharp edges of the aluminum. I decided to keep the package simple and use two different sized aluminum soda containers....

For instance if you are looking to control dandruff and to sooth an itchy scalp, then you would add Tea Tree oil and Chamomile to your shampoo base. If you wanted to add extra shine to your hair with a great scent, then you would add Lemongrass and Rosemary. Here are some oil and herb combinations that you can used based on creating a shampoo that begins with 4oz of castile soap for placement in an 8oz bottle. * Dandruff Control: 1/2oz Tea Tree oil and 2 1/2oz strained Chamomile Tea. * Extra Shine: 2 1/2 oz strained Lemongrass Tea and 1/2oz Rosemary oil. * Control Oily Hair: 1/2oz Lavender oil and 2 1/2oz strained Sage tea. * Thicken Hair: 1oz Rosemary oil and 1/2oz strained Nettles. Once you have created your at home organic shampoo, you'll want to store the bottle in a cool and dark area. Because you are creating something using natural and organic ingredients, the product must be used and cannot have an indefinite shelf life as the chemical additive shampoos that are on the market today. * Making Your Own Organic Conditioner To create your own organic conditioner at home there is no need to use a base of castile soap.
