Growing crystals is a popular science fair project that teaches students about crystal formation, evaporation and saturation. Usually, a saturated solution is made and then allowed to evaporate to form molecular structures in the form of crystals. Growing crystals using traditional methods can take several weeks. You can expedite the process by using several different techniques and ingredients. Generally, crystals that are made in a couple of hours are finer and less resilient than crystals formed over the course of several weeks. Make crystals using salt instead of sugar as s faster. Fill your jar or glass 3/4 full with water. Place the water in the pot and bring it to a boil. Pour the water into the glass until it is 1/2 full. Mix 1 tbsp. salt into the water at a time until no more

We know that many of you struggle with having to wash your hair every day because the excess oil is unbearable, but getting to the root of the problem в quite literally в makes more sense than battling the beauty affliction (although some of these are hella cute). So here are 8 things to stop doing that could be the cause of your greasy hair. 1. Touching your hair too often Like constantly touching your face ( ) fiddling with your hair в flirtatiously or out of boredom в transfers oils from your fingertips to your strands. Also try and (nicely) discourage your boyfriend from touching your hair too much in bed в feels nice but doesn't look nice come morning. 2. Over-washing Yes, you wash it to cleanse the grease, but no, it doesn't help. Unfortunately daily shampooing can strip your scalp
Molecules of food are held together by chemical bonds that contain stored energy, explains Scitable by Nature Education. When the digestive system breaks down these foods by breaking those bonds, it releases that energy, as noted by GroupHealth. GroupHealth further explains that the energy is then converted into a form that cells can easily use, usually glucose, to fuel their operations. The glucose transitions from the digestive system to the circulatory system, where it travels throughout the body through the blood vessels, according to the University of Illinois at Chicago. The blood delivers this energy to all of the body's systems and organs. Heart cells, for example, need energy to keep the heart beating, as explained by the McKinley Health Center, and the lung cells need energy to

Do youВunderstand the importance of getting a good nightвs sleep, every night? Itвs refreshing, healthy and generally beneficial to our lifestyles. And besides, there s rarely aВmore enjoyable experience than settling down snugly in aВcomfortable bed and drifting off to a nice, restful sleep. But do we actually need 8 hours sleep? Thatвs the number that most people quote and that regularly springs to mind when discussing sleep length. But, is eight hours sleep enough, or is it too much, or too little? Well, letвs kick off the debate with the view of, director of Loughborough Universityвs Sleep Research Centre, who quite firmly states that we donвt need 8 hours at all. In fact, he says: Itвs nonsense. Itвs like saying that everybody should have size eight shoes, or be five foot eight
If you know a few computer languages and a little history you probably have some ideas about how they relate to one another. If informal ideas aren't quite what you want, how about a full taxonomy derived as if the languages were species? I need to say right at the start that most of the conclusions of this research fit in with your preconceptions of how languages fit together - or they should. Sergi Valverde and Ricard Sol working at the Santa Fe Institute have taken the methods of computational evolutionary theory and classified languages into clades to form a phylogenetic network or evolutionary tree. The aim of the research is to clarify whether cultural evolution is like biological evolution, but the specific results about programming languages are still interesting to us
General Zaroff bought the island after he got bored with hunting ordinary game. P Zaroff was an aristocrat that got forced out of Russia with the revolution. P His family had been very rich, and he managed to hold onto his money despite the economic turmoil that followed. PP "After the debacle in Russia I left the country, for it was imprudent for an officer of the Czar to stay there. Many noble Russians lost everything. I, luckily, had invested heavily in American securities, so I shall never have to open a tearoom in Monte Carlo or drive a taxi in Paris. P P Zaroff continued to travel the world hunting more and more exotic game, but it was boring for him. P He had been a hunter since he was a child, and it was the only thing he found exciting in life. P When Rainsford asks Zaroff what
Twelve-year-old Cindy woke up one morning and felt familiar pain in her lower belly. She knew what it was and grumbled, "Oh, no. Here comes another period. " Cindy started her period over a year ago. She's learned to handle using pads and tampons, but the cramps are really bothering her. Sometimes Cindy feels so bad that all she can do is lie down. Let's find out what cramps are and what to do if you're a girl who gets them. What Are Period Cramps? Lots of girls experience cramps before or during their periods. Cramps are caused by prostaglandins (say: pross-tuh-GLAN-dinz), chemicals a girl's body produces to make the muscles of the uterus contract. The contracting muscles help push the blood out through a girl's vagina during her. You probably know periods usually come once a month.
What is Easter about? Easter is a Christian festival that celebrates the resurrection of Jesus Christ. The Bible says Christ died on the cross on Good Friday and came back to life three days later. Easter is on different dates each year, between 21 March and 25 April, depending on when there's a full moon in spring. There are some unusual modern traditions associated with it. Why do we have Easter eggs? A lot of us may chomp on chocolate eggs at Easter, but originally eating eggs was not allowed by the church during the week leading up to Easter (known as Holy Week). So any eggs laid that week were saved and decorated to make them "Holy Week eggs", then given to children as gifts. Victorians adapted the tradition with satin-covered cardboard eggs filled with Easter gifts. ...
