When you think of a museum, I bet you don't think of a place where children run around. But the Science Museum is different. It's noisy!

You can get to the Science Museum by going on the London Underground from Waterloo on the Jubilee line to South Kensington. When you walk out, take a look around you, and you could see it.

What to bring: at least two bottles of drink for the kids and 10 pounds to spend in the cafes. Entrance is free!

The most interesting part of coming here is to go to the kids' area, the Launch Pad on the 3rd floor. At busy times, you may have to wait in line, but staff will provide science. It should indulge(满足) you as you will learn about science in a funny way. There are also simulators(模拟装置) in the 3rd floor, so think of Floor 3 as a "fun floor".

If you want to learn about the museum, then go to the ground floor. They have some things which will interest you.

Overall, it's a fun experience for the kids and you may enjoy it too. It's also free to get in!

Many children use the Internet to get useful knowledge(知识) and information, and to relax in their free time. But some of them are not using it in a good way. Here are some rules to make sure you are safe and have fun on the Internet.

◆Make rules for Internet use with your parents. For example, when you can go online, for how long and what activities you can do online.

◆Don't give your password(密码) to anyone else, and never give out the following information: your real name, home address, age, school, phone number or other personal information.

◆Check with your parents before giving out a credit(信用) card number.

◆Never send a photo of yourself to someone in e-mail unless(除非) your parents say it's OK.

◆Check with your parents before going into a chat(聊天) room. Different chat rooms have different rules and attract different kinds of people. You and your parents will want to make sure it's a right place for you.

◆Never agree to meet someone you met on the Internet without your parent's permission(允许). Never meet anyone you met online alone.

◆Always remember that people online may not be who they say they are. Treat (视为)everyone online as if they were strangers.

◆If something you see or read online makes you uncomfortable(不舒服), leave the site. Tell a parent or teacher right away.

◆Treat other people as you'd like to be treated. Never use bad language.

◆Remember—not everything you read on the Internet is true.

How do you deal with plastic bags from the supermarket? Throw them away or reuse them? How about eating them?

Envigreen in India has made a bag with 12 natural ingredients (食材), such as potatoes, vegetable oils and bananas. It looks and feels just like the usual plastic bag, but can break down. The bags aren^’t harmful to the environment. Both humans and animals can safely eat them. The founder of Envigreen, Ashwath Hedge, spent four years trying them out.

Although the Envigreen bags are much more expensive than those usual plastic bags, they are good for our environment. Usually, it takes about 1000 years for usual plastic bags to break down. But an Envigreen bag can naturally break down in less than 180 days. It also dissolves (溶解) in less than a day in water, and in about 15 seconds in boiling water. Maybe the Envigreen bags are a solution to the world problem of plastic pollution.
