Building blocks (积木) are still one of the most popular traditional toys today. Their interesting design and easy use attract children of all ages. Most traditional toys, like building blocks, were first made of wood. Today, wooden building blocks are still used, and now there are several other types of building blocks to choose from, like plastic building blocks.

Children build all kinds of things that they see in everyday life with building blocks. This gives them the chance to learn new things and life skills.

Building blocks can help children practice their language skills. Most children talk to each other as they build things with these traditional toys. This type of toy also helps develop the skills that children need in life. As they begin to join groups playing with building blocks, they learn to take turns, share, and solve problems with others. However, these are not the only advantages of playing with building blocks.

Building blocks can also help develop children’s skills in math and science. They allow children to work according to the steps of scientific discovery. Traditional toy building blocks also come in different shapes, colors and sizes. These types of building blocks encourage children to develop skills in dividing things.

Playing with building blocks is not only fun but also very helpful. Maybe that is the reason why building blocks are still popular today.

Will there be gardens in space?

Astronauts on board the International Space Station (ISS) recently made history by taking bites of some red romaine lettuce(生菜). They became the first humans to eat food that was grown entirely in space.

The lettuce was planted on the ISS in a small greenhouse called “Veggie”, which uses LED lights to help plants grow in space.

First, astronauts cleaned the lettuce with special sanitizing wipes and then ate it with some salad dressing.

“It was one small bite for man, one giant leap for our journey to Mars,” one astronaut Scott Kelly later posted on social media.

Space vegetables are part of the NASA experiment called “Veg-01”, a study on how plants grow away from the effects of Earth’s gravity. It will allow astronauts to grow and eat their own food during long space explorations.

“If we’re ever going to go to Mars someday, we’re going to need a spacecraft that is much more self-sustainable in its food supply,” said Kelly.

Growing fresh plants on a spacecraft may also provide oxygen and help astronauts alive, NASA said.

“Veg-01” started in May 2014. The first batch of vegetable took 33 days to grow in space before they were taken back to Earth for a safety check.

After making sure it was safe to eat, astronauts planted a second batch on July 8. They let the plant grow for another 33 days and were then able to eat it.

Astronauts usually only get some fruit and vegetables when a supply ship comes to the ISS. Now with the vegetables grown in space, they can eat whenever they want.
