If you are looking for something fun and educational to do in Maryland, why not visit the Maryland Science Center? It is located at 601 Light Street, Baltimore, MD 2. The ticket prices vary depending on ages, groups and the exhibits you choose.

The Maryland Science Center is basically a museum, but it gives everyone a chance to learn through experience and play, rather than just glance at an exhibit.

You can learn about various topics, including outer space, the human body, dinosaurs, electricity, marine(海洋的) biology, energy, and much more. You can also take part in the interactive activities, such as racing bubbles, digging for dinosaur fossils, using puzzle pieces to construct cars, and so much more.

At the Davis Planetarium, you can lie back in a chair and look at the stars while still inside the Science Center. The stars will appear on the ceiling of the theatre as you watch them.

There are different shows to catch at the Davis Planetarium. You can learn about the galaxy and astronomy during the Dark Matters show. Learn about the stars and planets during the Sky Live show. The One World One Sky show allows children to explore the stars. The Live from the Sun show will teach you all about the hot sun.

For children, they can’t miss the Kids Room. They will be able to play in a water area, construct dams and water towers, push buttons, ring doorbells, build with blocks, and more, and definitely they will learn a lot. In addition, there is also an area for kids of two years old and under, where they can crawl, walk and explore safely with soft toys.

Some of my earliest memories of Mother come from the time we lived in Prairie Village. I was about 3 years old. Mother would take me on nature hikes along the small river’s banks.

In the bushes we found insects, cocoons (茧) and butterflies. She made a butterfly net for me. While running after a butterfly in our back yard, I put the net down. Mother and I built snowmen, much taller than I, and we laughed aloud after a snowball fight. In the season of rain and flowers, singing birds and sunny mornings, the cocoon broke open, and a brilliant white butterfly came out.

One of our favorite books was “The Tale of Mr. Jeremy Fisher.” I would sit at Mother's side as she read the story. I consider the years spent with Mother “On the River” a foundation to a lifelong interest in science, inspiring me, in part, to choose a career in medicine. I recall sitting with Mom on the front of the house in Baldwin late one June evening. Dad’s tail-lights were disappearing quickly as he drove off to see his Dad, who was dying in Garnett.

Mom said, “Oh, kids, we’re only here for such a short time....” Her words were also kind of scary to me at the time, because what I heard her say was that we are all destined (注定) to die, and she had told me once before that she was afraid to die. I guessed her message was more than “Our life on earth is short and we are all destined to die” She meant that “Make the most of life while you can, here on earth. Reach for the stars!” Mother also said “Oh, kids! We’ll have the stars!” She had 5 of the stars she’d brought onto this earth. In 1963, 6th star was added, named Kip.

All of us did well in our life. 1971 found me attending Baker University, and I found a star and married her in the middle of medical school. I have added four more stars: Dean, Christine, Dan, and Dave. Dean found a star and married her. He and Shakeena now have 3 stars: Demetrius, Olivia, and Maxwell. Mom loved babies, children, and youth so much... We have the stars!

Marco Springmann and his colleagues, at the Oxford Martin School's Future of Food Programme, built computer models that predicted what would happen if everyone became vegetarian by 2050. The results indicate that if the world went vegan, the greenhouse gas emissions declines would be around 70%.

In the US, for example, an average family of four emits more greenhouse gases because of the meal they eat than from driving two cars——but it is cars, not steaks, that regularly come up in discussions about global warming.

Food, especially livestock, also takes up a lot of room. 68% of agricultural land in the world is used for livestock. When these lands become grasslands and forests, they would capture carbon dioxide and further ease climate change.

However, if the whole world went vegan, there would be negative effects too. First, it is necessary to keep livestock for environmental purposes. "I'm sitting here in Scotland where the Highlands' environment is very man-made and based largely on grazing by sheep," says Peter Alexander, a researcher in socio-ecological systems modeling at the University of Edinburgh. "If we took all the sheep away, the environment would look different and there would be a potential negative impact on biodiversity. "

Plus, meat is an important part of history , tradition and cultural identity. Numerous groups around the world give livestock gifts at weddings, celebratory dinners such as Christmas with turkey or roast beef.

And nowadays, moderation in meal-eating's frequency and portion size is key to solving these conflicts. "Certain changes would encourage us to make healthier and more environmentally friendly dietary decisions," says Springmann, "like putting a higher price lag on meat and making fresh fruits and vegetables cheaper. "

In fact, clear solutions already exist for reducing greenhouse gas emissions from the livestock industry. What is lacking is the will to implement those changes.

Chengdu, the capital of Sichuan province, has an ancient competition with Chongqing, a city to its south-east. Residents of Chongqing accused their Chengdu cousins of being pompous (自大的). The people of Chongqing were hotheads, Chengdu residents shot back. Both cities share a love of spice-laden Sichuan cuisine, which in recent decades has occupied Chinese dinner tables. But they are at war over which has the best Sichuan hotpot—a type of DIY-cooking that involves boiling vegetables and slices of meat with chillies and numbing peppercorns.

A private museum in Chongqing, opened several years ago, makes the case for the Chongqing-style hotpot. It describes how it developed from a method used to make cheap offcuts of meat taste delicious. But Chengdu is playing catch-up. In January the city sold a plot of land on condition that the developer build a hotpot museum on part of it.

The two cities are among many in China with their own styles of hotpot. Hotpot restaurants in China are more profitable than other kinds. Haidilao, a well-known Sichuan-based hotpot chain, raised nearly $1bn when it was listed on the Hong Kong Stock Exchange (股票交易所) in September.

Not all Chinese warm to hotpot. Some older Sichuanese refuse to be connected with it. They complain that it is causing overuse of chilli in other dishes that cover up the original genuine flavours.

But Chengdu’s plans for a museum suggest that Sichuan hotpot is not only growing in popularity, but is also becoming symbolic. If it can set the West on fire, officials may hope it will become a delicious new source of Chinese soft power. There will be plenty of glory for both Chengdu and Chongqing to take pride in if that happens.
