    Today I Ate a Rainbow is a useful game about our health. It makes eating a rainbow of fruit and vegetables fun for kids! In the game, the teachers or parents use a colorful rainbow chart(图表)and bright colorful magnets(磁铁). Children know about the fruit and vegetables they eat the whole day.

    "Sometimes it can be really difficult to get children to eat their fruit and vegetables, "says Mrs Welles. "My little son is weak, and he doesn't like fruit or vegetables. He likes to eat junk food. I think this chart can help him know about how much fruit and vegetables he eats every day. I'm sure the idea can work well."

    Fruit and vegetables have vitamins, minerals and nutrients. Many nutrients give fruit and vegetables bright colors. The brighter, the better! The chart is made up of these important colors: red, orange, yellow and green. The different bright colors show the different nutrients that each fruit or vegetable has. So we can use the rainbow colors as a guide to know what we should eat today.

    Up to two thirds of children don't get as much sleep as they should do. and this can make them nervous and slow at school, researchers say.

    So how long should young people sleep each night? The answer is between and 10 hours. If you don't get enough sleep at night, you'll have less energy the next day.

    But the researchers say many children have missed out on 4,500 hours of sleep by the time they are seven years old. They say that children miss sleep because they have TVs and computers in their rooms, and busy parents don't read to their younger children at night any more. The traditional "bedtime story" helps children to relax and fall asleep peacefully. Children with TVs and computers in their bedrooms were more likely to sleep badly, and to get less than eight hours' sleep. Even losing one hour's sleep a night can mean that children do less well at school.

    German scientists think that your brain keeps working while you're asleep. To show that they were right, they gave two groups of people a problem to work out. One group went to sleep, and the other group stayed awake. The result? The people who slept worked out the answer more quickly, suggesting their brains had been trying to find the answer while the people were asleep. So, make sure you get enough sleep tonight, and you'll be at your best tomorrow!
