Teen Life Magazine
The School Science Festival will start next week. We are looking for students’ ideas for new inventions to put on the school website. Please write an article about your idea for a new invention and send it to us.
Wang Yao drew a mind map before she wrote about her idea for a new invention—a flying car. Look at the mind map and read her article to find out how she organized her idea.

A flying car
My invention is a flying car. It is fast, convenient and green.
The flying car has four wheels and two wings. It can run on land and fly in the air. It has a top speed of 300 km/h. You can travel farther distances in less time. The car can be controlled by voice. If you shout “Fly!”, the car will turn into a plane in 30 seconds. Then you can fly in the air. You will be as free as a bird. Instead of petrol, the car uses solar power, so it will not pollute the air.
As there are more cars on the road, there are more traffic jams. My invention will help people avoid traffic jams. It will make driving a more exciting experience too. People can fly anywhere they like and enjoy the view at the same time.

A Multifunctional Schoolbag
My invention is a multifunctional schoolbag. It is light, smart and full of surprises for students.
The schoolbag looks like a common one but has many special parts. It has a small solar panel on the back, several hidden pockets and a built-in tablet. It can light up when it’s dark, so you can find your books easily. If you press a button on the side, it will weigh your books and tell you if you’re carrying too much through a small speaker. It also has a USB port, so you can charge your phone or watch when you’re at school. Instead of being made of heavy material, it’s made of light and waterproof cloth, so it’s easy to carry and can protect your books on rainy days.
As students have to carry many books every day, some may feel tired or even hurt their backs. My invention will make school life easier and more enjoyable. It can help you manage your school things well and bring you more convenience.
A Smart Pet Feeder
My invention is a smart pet feeder. It is automatic, convenient and helpful for pet owners.
The smart pet feeder is round and has a digital screen on the top. It has a food container and a water container. It can feed pets automatically. You can set the time and amount of food through the screen. For example, if you set it to 8 a.m., it will give your pet food at that time. It can also play soft music to make your pet feel relaxed when eating. Instead of needing you to feed pets manually every day, this feeder saves your time, and it is very easy to clean.
Nowadays, many people are busy with work and often forget to feed their pets on time. My invention will help pet owners solve this problem. It will make taking care of pets much easier. Pets can get food regularly and healthily, and owners can feel more at ease even when they are not at home.
