Learning with Legos For more than 60 years, Lego bricks(砖块) have developed children's imaginations. Now, a new form of these toys is called Lego Braille Bricks. It is being tested around the world.

Lego Braille Bricks are designed to help people learn Braille(盲文). That's a system of writing in which letters are replaced by raised knobs(凸起). The small knobs on the bricks are put as Braille letters. Blind children can use their fingertips to read the knobs to learn Braille. According to the World Health Organization, 36 million people worldwide are blind. In the United States, only 10% of blind children learn Braille. Lego Braille Bricks can help change that.

Braille Bricks will be launched(上市) by Lego in 2020. For some schools, it will be free. The Danish Association of the Blind was one of the first organizations to come up with the idea of using Lego bricks to teach Braille. Thorkild Olesen, the president of the organization, is blind. He says many teachers don't have the tools and skills to help kids learn Braille. So they teach with audio tools, such as audio books. "Like any other people, we need to express ourselves in writing, " Olesen told TIME for Kids." Audio is great. But it can never replace Braille. Braille is the most important tool for us. It is the best way for blind people to learn to spell correctly, write, and read like common people."

Olesen's organization shared his idea for Braille Bricks with the Lego Foundation(基金会). Olesen explained to the toy maker that the knobs on Legos are similar to Braille letters. Stine Storm is a project manager at the Lego Foundation. She liked the idea of turning Lego bricks into a learning tool. "It was a fun and playful way to teach Braille to blind children," she says, "Lego Braille Bricks will also have printed letters on them that match the Braille letters, so sighted children and blind children can play with the Legos together."

The way to see water's temperature

Here's how to tell whether a glass contains(容纳)hot water or cold water-without ever touching it!

You'll need

•2 drinking glasses that are exactly alike

•Ice cubes(块)

•Adult helper

•Bathtub(浴缸)or shower

•Pencil and paper

1.Fill one glass with cold tap water and cool it with ice cubes. Don't use a lot of ice; just cool it a little.

2.Fill the other glass with very hot water.

3.Pour both glasses out into the tub at the same tirme and speed.

Repeat this process(过程)a fewtimes,and watch closely each time.

4.Ask your helper to fill the glasses again and not tell you which is which.

When you see the water splash in the tub.guess which one is the hot water.

5. Repeat several times. Keep score on your paper.

You should be able to guess correctly more than half the time.

Cold water is more dense(稠密的)than hot water.so a cup of cold water is just a little bit heavier than a cup of hot water.

When you pour hot water onto a hard surface,it splashes(溅起)around more than the cold water because it's less dense.
