lay up to 100 eggs. Several independent studies have shown that the. To prevent yolks from drying out‚ cover them with a little cold water. Drain the water before using. When storing hard-cooked eggs‚ you may notice a "gassy" odour in your refrigerator. The odour is caused by hydrogen sulphide‚ which forms when eggs are cooked. It’s harmless and usually dissipates in a few hours. Fresh shell eggs By best before date Leftover yolks or whites Within 2 to 4 days Hard-Cooked eggs Within 1 week

Helicopter Experiment Prediction: As the mass on the helicopter’s copters increases‚ the speed taken for the rotors to spin down faster‚ this is because there will be more downward pull from gravity‚ as the terminal velocity for a paper helicopter is low. Variables: Independent variable will be the mass that we change throughout the experiment. The dependant variable will be the time that we measure for the helicopter to reach the floor. Finally the controlled variables include‚ the helicopter

Kevin Doherty Experimenting with Plant Growth Team Rocket Science Introduction: The purpose of the experiment was to establish whether the concentration of Schultz fertilizer that was added to the radish seeds effects the speed of growth during the six-week time frame of the study. The major variables with this study are proficient communications among the team‚ the seeds‚ soil‚ water concentration‚ fertilizer‚ light exposure‚ temperature of the room‚ consistency of following watering (watering

In order to find the connection between the level of education and income‚ research methods need to established. To find the relationship between the two‚ I would use the methods of survey and experiments. Survey method allows a collection of a specific population and from that populations a sample population can be extracted to represent the whole. Given a random survey preformed at a local festival would give the general population a chance to participate since all sorts of people attend community

In this laboratory experiment‚ our control was the Daphnia that gets spring water‚ whereas the drugs were the independent variable and the heart rate was the dependable variable. The first step our group did was to place the Daphnia into a clean depression slide. Next‚ we added a small drop of the spring water and put a cover slip over the slide. Then‚ we waited for one minute prior to placing the slide

SUMMARY The aim is to observe distillation process of ethanol-water solution and to measure the alcohol content after process in this experiment. 500 ml of solution with an alcohol content of 32% (v/v) is used for this experiment. Temperature values are recorded for every 10 ml alcohol obtained in the flask. The process is repeated in our experiment and for the first process‚ the data collection process continues until the distillate reaches to 200 ml. The concentration of alcohol is measured for

The effect of varying temperature on thee Rennin enzyme Abstract The purpose of this experiment was to see what affect different temperate had on the reaction rate of the enzyme rennin. The experiment was performed by placing test tubes filled with renin and milk into water bath which was heated or cooled to one of the temperatures trialed. The hypothesis justified because it found because it though data that the enzyme reacted faster with the 45° temperate because it was

Chemical Properties of Egg Tempera Art is traditionally viewed as a creative process far removed from science. However‚ beyond the imaginative efforts that contribute to the creation of a work of art are the physical materials that are used as the medium. While science is not an essential part of the thought and design process‚ an understanding of the chemical properties of different art media is integral to creating a work of art that will not only match the artist’s vision but will also stand
