       Bicycles are a great way to get around. They’re fun to ride, especially down hills. And, as you speed along the road, you might also think of ways in which you could improve your bike— make it safer, more efficient, or more comfortable. In fact, the two-wheeled machines make for some cool science projects.

This year's Intel International Science and Engineering Fair (ISEF), held last May in Cleveland, featured(had)three bicycle projects from three countries. Like many of the other experiments presented at ISEF, the bike projects showed that some of the most interesting scientific research often begins by taking a closer look at things you care about.

       Renato Angulo Chu had even grander ambitions. The 12th-grader from Lima, Peru, wanted to address some of his country's economic troubles.

"I see a problem in my country," Renato said. "If you go to the forests in Peru, in some places you cannot find electricity. If you go with my bicycle, you can turn on the lights."

Renato, 16, spent 3 years designing his special Multibike. The device looks like a fixed exercise bike. It has wires fixed along the frame and a blender strapped(fastened) to the back. Turning the pedals operates the blender. The same principle can be used to sharpen knives or sweep city streets.

       The Multibike can work either as a fixed bike or as a bicycle able to travel city streets and country roads. It's made from inexpensive materials, and the user gets exercise while pedaling to operate a machine.

"You pedal the bike, and you can mix any drink you want," Renato said. More importantly, he added, the same concept could be used to bring light to houses in remote regions of the rainforest.

Every child is unique and has interests and wants that are specific to him or her. As parents of many children, it takes a lot of effort to identify the special qualities of each child and use them to be an effective influence in their young lives. What’s more , parents need to work to guide each child into their place in the family and make sure that the child is content and able to grow as a person.

Establishing  tasks in the home for each child helps  begin to lay  relational boundaries  in place. Each child should have an area  that becomes his or hers to maintain. Household chores (家务活 ) fall into this category. However, an order for answering the phone or doorbell can also be a task.  Reward each accomplished task in small ways like a compliment ( 赞扬). Money is not as  effective as personal attention.

Don’t buy a gift or treat for one without including the others. Even on birthdays give every child a small gift that they can enjoy opening while the birthday child opens his or her pile of gifts or larger gift. It’s not a really pricey thing. Our children never felt left out at the other child’s birthday or special occasion.

When buying clothes or other necessities, it can often be too much of a budget strain ( 紧张) to buy everything for all at once.  Make sure every child understands that their turn will come. If you buy back to school clothes, be certain to have each one a new outfit to wear by the first day of school.  Start early so each child can receive  parental attention before heading out.

Don’t fall into the trap of bragging ( 夸耀) on A’s by a smart or overachieving child and ignoring the C’s of a average child. Encourage them to do their best and brag on their best , not the letter grade received.
