My name is Peter Watson, and I am the Public Pro­grams Manager at SciTrek, the Science and Technology Museum of Atlanta. Our museum has over 100 exhibits which help to show the principles of science in our every­day lives. Each exhibit is designed for you to do more than just look at it. You can actually experiment with the equipment to learn more about science. One of our ex­hibit halls is the Hall of Simple Machines. In this hall we also have exhibits about Bernoulli's princi­ple. This is the principle about relative air pressure which engineers use to design the wings of airplanes.

We also have a Hall of Electricity and Magne­tism, a Hall of Light, Color, and Perception, and a special area for children under the age of 7 which we call "Kidspace." In addition to these exhibit halls, we have the "Mathematics" exhibit area which is all about the different areas of mathema­tics. This exhibit was first made for the World's Fair in New York in 1964. Our museum also has an electric technologies hall which we call "Power Your Future" and a large theater where we perform our science shows.

We perform our science shows while the mu­seum is open for all of our visitors. We have per­formances and demonstrations about electricity, bubbles, and Newton's Laws of Motion. Can you name the three laws of motion? Our newest show is about the weather in Atlanta. It explains and il­lustrates the scientific principles behind our hot summers, mild winters with hardly any snow, and about the thunderstorms we have that sometimes bring tornadoes.

The museum also has a summer camp where children come to spend the day having fun with science and an overnight camp-in program for all-night science excite­ment. When children and adults come to our overnight camp-ins they sleep on the floor of the museum, right there under all the exhibits!

On selected weekends during the year, our museum is also the site where Atlanta residents can bring items to be recycled and to learn more about how recycling can help the environment. Everyone in our museum recycles everything possible at work. Our waste paper is recycled, our aluminum cans, and even our newspapers are all saved for recycling. Every time we recycle, we save the energy, waste, and pollution associated with production from raw material. We also teach classes for students and their teachers about our precious water resources and how to preserve them. Do you know where your drinking water comes from? What are you doing to help keep it clean and safe?

I hope that you get to come visit us someday and see our museum. You can learn so much by doing, that is one of our guiding principles; and you will be able to do so much at our museum. But even without leaving your home, here is an experiment you can do with your pa­rent's help. Boil some red cabbage and set aside the pur­ple juice or rub a red radish on some white paper. The purple cabbage juice and the red radish paper are acid/ base indicators. They will change color in the presence of acids or bases (alkalis).

Test some lemon juice or baking soda or aspirin or salt or other safe household substances. Acids will turn pink. Bases will turn blue/green. Neutral substances will not change color at all.

I hope you enjoy experimenting and having fun with science!

 

1. Прочитайте текст без использования словаря для общего понимания прочитанного.

2. Если вам это удалось, то озаглавьте текст. Если вы с трудом поняли содержание текста, то прочитайте текст со словарём для полного понимания прочитанного, выписывая при этом слова и выражения в словарь, т.е. выполняя следующий пункт плана. Только затем озаглавьте текст.

3. Составьте словарь по тексту, содержащий не менее 30 слов и выражений. Словарь следует составлять и тем, кто не испытывает трудности в понимании текста при беглом чтении. В этом случае в словарь нужно внести слова и выражения, о значении которых вы догадываетесь, но не знаете его точно, либо важные на ваш взгляд для пересказа, для чтения текстов по вашей специальности и т.д.
