If you're scratching your head all the time, get your parents, a doctor, or the school nurse to check your hair out. If you do have lice, you'll have to wash your hair with a special shampoo and then get your mom or dad to use a special lice comb to comb out the eggs that are still stuck in your hair. The shampoo will kill the lice right away and the itching should stop within a few days. You also need to wash all your clothes , blankets, hats, combs and brushes in water that's hot enough to kill any lice that are still hanging around. Remember, the best way to prevent lice is not to share stuff that other people put on their heads. Don't try on another kid's hat and never share combs or brushes.

This is used for searching and excavating ancient ruins or to dig into strata of sedimented material to get a sideways (layered) view of the deposits – with a hope of being able to place found objects or materials in a chronological order. The advantage of this method is that it destroys only a small part of the site (those areas where the trenches, often arranged in a grid pattern, are located). However, this method also has the disadvantage of only revealing small slices of the whole volume, and modern archeological digs usually employ combination methods. [4]

The first descent to the bottom of the Mariana Trench took place on January 23, 1960. The French-built . Navy-operated bathyscaphe Trieste —with Swiss ocean engineer Jacques Piccard (who helped his father, Auguste Piccard , design the bathyscaphe) and . naval officer Don Walsh aboard—made a record dive to 35,814 feet (10,916 metres) in Challenger Deep. The next person to descend into that location did so more than 50 years after Piccard and Walsh. On March 26, 2012, Canadian filmmaker James Cameron piloted the submersible Deepsea Challenger (which he had helped design) to 35,756 feet (10,898 metres), in the process establishing a new world record depth for a solo descent.
