QUES: Grim disappeared upstairs himself, and returned about ten minutes later in the uniform of a Shereefian officer--that is to say, of Emir Feisul's Syrian army. Nothing could be smarter, not anything better calculated to disguise a man. Disguise, as any actor or detective can tell you, is not so much a matter of make- up as suggestion. It is little mannerisms--unstudied habits that identify. The suggestion that you are some one else is the thing to strive for, not the concealment of who you really are. Grim's skin had been sun-tanned in the Arab campaign under Lawrence against the Turks. The Shereefian helmet is a compromise between the East and West, having a strip of cloth hanging down behind it as far as the shoulders and covering the ears on either side, to take the place of the Arab head-dress. The khaki uniform had just enough of Oriental touch about it to distinguish it from that of a British officer. No man inexperienced in disguise would dream of choosing it; for the simple reason that it would not seem to him disguise enough. Yet Grim now looked so exactly like somebody else that it was hard to believe he was the same man who had been in the room ten minutes before. His mimicry of the Syrian military walk--blended of pride and desire not to seem proud--was perfect.

QUES: You may wonder if there are other examples of static discharge. The answer is yes. Lightning is a form of static discharge. It is much more dramatic than what happens between you and the door knocker, but it is the same principle. You can see how it occurs in the following diagram and animation. You have no doubt seen lightning in a rainstorm. What does lighting have to do with static electricity? As it turns out, everything! During a rainstorm, clouds develop regions of different charges. This happens due to the movement of air molecules, water drops, and ice particles. The negative charges are concentrated at the base of the clouds. The positive charges are concentrated at the top. The negative charges repel electrons on the ground below. The ground then becomes positively charged. Over time the differences increase. Eventually the electrons are discharged. This is what we see as lightning. You can watch an awesome slow-motion lightning strike below.

QUES: Plants also detect the daily cycle of light and darkness. Do you know how plants respond to these changes? Some plants open their leaves during the day. It is during these hours the plant can collect sunlight. At night, the plant closes its leaves to prevent water loss. Many plants respond to the change in the length of the day. As days grow shorter, some plants respond by going dormant. Dormant is when a plant suspends its growth. It does this in order to survive. Shorter days signal the coming of winter. Winter in most areas means extreme cold. It is also very dry in the winter months. As winter approaches, some plants respond by their leaves changing color. After the change in color, they fall off. This dormancy period helps trees. It allows them to survive the cold and dry winter. Plants only want to grow when conditions are right.

QUES: Josie started planning her new garden in the winter. She chose flowers and vegetables that could grow in her area. She looked through the seed magazines. She ordered the tastiest kind of each vegetable and the prettiest kind of each flower. She talked to a friend about her plans. It seemed like the snow would never melt. But Josie didn't have to wait for spring to get started. Six weeks before the last frost, Josie planted seeds indoors. The tiny seedlings pushed up through the soil and began to grow. Finally spring arrived. Each day, Josie moved the seedlings outside for a few hours so they could get used to the cooler temperatures. Josie worked in her garden, digging the soil. She added a special growing mix from the garden store to make the soil better. When everything was ready, she removed the seedlings from their trays and planted them in her garden. The warm sun and rich soil helped her vegetables and flowers grow.
