ГДЗ по английскому языку, 10 класс, Афанасьева, номер p152.5: Science Across the Curriculum

Мы выберем четыре наиболее распространенных типа термометров для нашего исследования:

• Ртутный медицинский термометр (Mercury-in-glass thermometer)
• Цифровой термометр (Digital thermometer)
• Инфракрасный термометр (Infrared / Non-contact thermometer)
• Биметаллический термометр (Bimetallic strip thermometer)

Ниже представлены короткие тексты на английском языке, которые можно использовать в проекте.

1. Mercury-in-glass Thermometer

This traditional medical device consists of a glass tube with a bulb at one end containing mercury. When exposed to heat, the mercury expands and rises up the tube, indicating the temperature on a scale. Although accurate, these thermometers are becoming less common due to the toxicity of mercury if the glass breaks.

2. Digital Thermometer

A digital thermometer uses electronic sensors, such as thermistors, to measure temperature. The data is processed by a microchip and displayed on an LCD screen. They are popular for home use because they provide quick readings, are easy to read, and do not contain hazardous materials like mercury.

3. Infrared (Non-contact) Thermometer

Also known as a forehead scanner or ear thermometer, this device measures thermal radiation emitted from the body without physical contact. It detects infrared energy and converts it into an electrical signal to calculate temperature. These are widely used in public places for screening large numbers of people quickly and hygienically.

4. Bimetallic Strip Thermometer

This type is often found in ovens, thermostats, and industrial settings. It works based on the principle that two different metals expand at different rates when heated. As the temperature changes, the strip bends, moving a pointer along a dial. It is durable and does not require batteries, making it suitable for high-temperature environments.

Чтобы успешно представить проект, следуйте этим рекомендациям:

1. Визуализация: Подготовьте слайды или плакаты с изображениями каждого термометра.
2. Структура выступления: Начните с введения («Today we will talk about...»), затем по очереди расскажите о каждом типе, используя написанные абзацы.
3. Интерактив: Задайте классу вопрос: «Which thermometer do you think is the most accurate?» (Какой термометр, по вашему мнению, самый точный?).
4. Раздаточный материал: Распечатайте краткие карточки с определениями для одноклассников.
