1 . Blowing Up Balloons with CO₂
Chemical reactions (化学反应) make for some great experiments. You can make use of the CO₂(carbon dioxide) given off by a baking soda (小苏打) and lemon juice reaction to blow up your balloon!
What you’ll need:
●Balloon ●About 40ml of water ●Soft drink bottle
●Juice from a lemon ●I teaspoon of baking soda
Instructions:
●Before you begin, make sure that you pull the balloon long to make it as easy as possible to blow up.
●Put the 40ml of water into the soft drink bottle.
●Add the baking soda and mix it with water.
●Put the lemon juice in and quickly put the balloon over the mouth of the bottle.
What’s happening?
If all goes well, then your balloon should inflate! Adding the lemon juice to the baking soda creates a chemical reaction and produces CO₂. The gas rises up and escapes (逸出) through the soft drink bottle. It doesn’t, however, escape the balloon, pushing it outwards and blowing it up.

| C．250 ml water. | D．A teaspoon of baking soda. |
| A．Heat the water. | B．Drink some juice. |

4 . Colors can affect (影响) our feelings. Blue is a calm (冷静的) color. If you are feeling nervous (紧张), you can wear blue clothes or stay in a blue room. Blue is also the color of sadness. When someone says he’s feeling blue, he means he is sad.
White can also make you feel calm. So you can wear white too if you are nervous. And white often means a new beginning.
Green is the color of nature. It can give us more energy when we are feeling tired.
Some colors can make you feel warm. In cold areas, people usually use warm colors in their homes, like orange and yellow. Yellow is also the color of wisdom. Some people prefer this color when they study for exams. For example, they may use yellow school things.
Red is one of the strong colors. It often makes us feel active. But this color can also mean danger. So it is often used in stop signs (停车标志) and lights.

5 . It is known that not all heroes wear capes (披风), but Chris Van Dorn does, who has saved dozens of animals in animal shelters (收容所). He has given these animals a second chance of life while dressed as the Dark Knight.
Van Dorn has been a big fan of Batman and grew up watching the TV series about animals. He also became a fan of animal rescue (营救) when his family took in a shepherd dog named Mr. Boots.
“While dressing like Batman is not necessary to rescue animals — anyone can be a superhero by adopting (收养) shelter animals — it does keep the focus on saving animals, not the man behind the cape. The dress just makes everybody happy and smile. It’s special to see Batman walking around, and when they find out that he’s doing a good deed in the world, they get even more excited,” Van Dorn said.
Van Dorn always wanted to be an unknown hero. “When I was first starting out, I would sign everything ‘Bruce Wayne’ and not put my real name out there,” Van Dorn said.
Van Dorn will spend long hours in his Batmobile — a Honda Accord — to take four rescued animals at a time to their new homes. He hopes to be able to buy a large truck so he can transport even more animals. He also hopes to use his pilot’s license as a means to transport animals further away quickly.
Now Van Dorn wants to share what he does with more people, saying, “I challenge anyone to go to their local animal shelter because it’s a sad place, but if you can help out in any way — whether that’s to adopt a dog or just volunteer your time, then you should do it.”

6 . Compared with the obvious environmental issues we hear about every day, littering often takes a backseat-but it’s more pressing than we may think.
Some may say that a banana peel out of your car along the motorway would be a harmless action. Actually, they are wrong. A banana peel can take up to two years to decompose(分解)，and with a third of motorists admitting to littering while driving, that’s a whole lot of discarded banana peels, or much worse. An orange peel and a cigarette butt has a similar biodegrading(生物降解)term to that of a banana, but tin and aluminium cans last up to 100 years, and plastic bottles last forever, so do glass bottles and plastic bags.
Despite the fact that longer-lasting materials will serve to damage the environment and its animals for longer, we can’t only measure the severity of a certain type of rubbish by its lifetime. For example, despite having a fairly short biodegrading span, more than 120 tons of cigarette-related litter is thrown away in the UK every day. Similarly, our regular littering here and there has caused the UK’s mouse population to increase by 60 million. This suddenly isn’t so mysterious when you consider that since the 1960s our annual littering has increased by an amazing 500%.
It’s not a cheap habit either: UK taxpayers spent $500 million on keeping the streets clean. So, it’s not surprising that if caught fly-tipping, you could face a $20, 000 fine. Regardless of how severe the punishment might seem, however, among the reported cases only 2, 000 were punished out of 825, 000, so we still have some way to go in making sure people observe the rules.
To take back our beautiful cities, we need to do more than simply not leaving rubbish where it ought not to be. We need to care more about the world around us.

9 . The great increase of waste that you find around the world is hard to ignore. Depending on where they live, people produce between 0.11 and 4.54 kilograms of waste every day. Even more alarming, that number is expected to increase by 70 percent by 2050.
Is there anything specific you can do to help the situation? One thing is to shop smart. Buy from companies that promote sustainable (可持续的) business practices and use recycled materials in their products.
Here are some products and companies that hit the mark for being environmentally-friendly.

10 . Animals are natural resources that people have wasted all through our history.
Animals have been killed for their fur and feathers, for food, for sport, or simply because there were in the way. Thousands of kinds of animals have disappeared from the world forever.
Hundreds more are on the danger list today. About 170 kinds in the United States alone are considered in danger. Why should people care? Because we need animals. And because once they are gone, there will never be any more.
Animals are more than just beautiful and interesting. They are more than just a source of food. Every animal has its place in the balance of nature. Destroying one kind of animal can create many problems. For example, when farmers killed large numbers of hawks(鹰), the corn and grain they stored would be destroyed by rats and mice. Why? Because hawks eat rats and mice. With no hawks to keep down their numbers, the rats and mice multiply(繁殖) quickly.
Luckily, some people are working to help save the animals. Some groups raise money to let people know about the problem. And they try to get the governments to pass laws to protect animals in danger.
Quite a few countries have passed laws. These laws forbid the killing of any animal on the the danger list. Slowly, the number of some animals in danger is growing.
