Since laboratories were introduced in the late s, the goals of high school science education have changed. Today, high school science education aims to provide scientific literacy for all as part of a liberal education and to prepare students for further study, work, and citizenship. Educators and researchers do not agree on the definition and goals of high school science laboratories or on their role in the high school science curriculum. The committee defines high school science laboratories as follows: laboratory experiences provide opportunities for students to interact directly with the material world or with data drawn from the material world , using the tools, data collection techniques, models, and theories of science. Science laboratories have been part of high school education for two centuries, yet a clear articulation of their role in student learning of science remains elusive.

Many types of apparatus are used for scientific work in the laboratories. Some of the items of common laboratory apparatus used in the laboratory are shown below. A Bunsen burner is a source of heat or mechanical appliances for which absolute safety is required while using Bunsen Burner. Mostly a knob is used to adjust the gas flow amount and a pivot collar that manages airflow. Both the knob and collar must be adjusted to get an excellent flame for heating things. It is usually made of stainless steel or Aluminium having three supporting legs. The apparatus to be heated is placed on the tripod stand.

Tripod stand

 Нет. Мы к нему не прикасались. Мой друг испугался. Он хоть и крупный, но слабак.  - Она кокетливо улыбнулась Беккеру.

 - Я… я не могу. Дэвид даже вздрогнул. Он смотрел в ее глаза, надеясь увидеть в них насмешливые искорки. Но их там не. - Сью… зан, - заикаясь, начал.  - Я… я не понимаю.

Похожий скорее на крепость, чем на танцевальное заведение, он со всех сторон был окружен высокими оштукатуренными стенами с вделанными в них битыми пивными бутылками - своего рода примитивной системой безопасности, не дающей возможности проникнуть в клуб незаконно, не оставив на стене изрядной части собственного тела.

Далее в заметке сообщалось, что, хотя алгоритм вызвал громадный интерес в Японии, несколько американских производителей программного обеспечения, прослышавших о Цифровой крепости, считают эту информацию нелепой - чем-то вроде обещания превратить свинец в золото. Формула, утверждают они, - это мистификация, к которой не следует относиться серьезно.

Сьюзан быстро проскочила мимо него и вышла из комнаты. Проходя вдоль стеклянной стены, она ощутила на себе сверлящий взгляд Хейла. Сьюзан пришлось сделать крюк, притворившись, что она направляется в туалет.
