This document provides a lesson on evaporation and drying. It explains that the rate of drying depends on conditions like temperature, air movement, humidity, and weather. Drying is fastest in hot, windy, and dry conditions, like outside on a sunny day or inside a clothes dryer, which maintains heat and circulation to quickly remove moisture from clothes.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
Synthetic Fiber Construction in lab .pptxPavel ( NSTU)
Synthetic fiber production is a fascinating and complex field that blends chemistry, engineering, and environmental science. By understanding these aspects, students can gain a comprehensive view of synthetic fiber production, its impact on society and the environment, and the potential for future innovations. Synthetic fibers play a crucial role in modern society, impacting various aspects of daily life, industry, and the environment. ynthetic fibers are integral to modern life, offering a range of benefits from cost-effectiveness and versatility to innovative applications and performance characteristics. While they pose environmental challenges, ongoing research and development aim to create more sustainable and eco-friendly alternatives. Understanding the importance of synthetic fibers helps in appreciating their role in the economy, industry, and daily life, while also emphasizing the need for sustainable practices and innovation.

This is a picture of damptowels on
a towel rack.
On Week 1, the rack of damp towels
was placed in an enclosed, cool
room.
On Week 2, the rack of damp towels
was placed on the patio, on a sunny,
windyday.
On which week do you think the
towels dried faster?

8. EXPLANATION
DRYING: The process by which moisture is removed from a material or substance. (Chung,
2017)
The rate of drying depends on several conditions.

9. A CLOTHES DRYER
A clothes dryer replicates
these ideal conditions by maintaining
high temperatures, and low humidity,
while constantly moving the clothes
around.
Some clothes dryers even blow hot air
over the clothes.
That is why a clothes dryer works so
fast!
10. SUMMARY
● Drying is the process by which moisture is removed from a material or substance
● This moisture is removed via evaporation.
● The rate of drying depends on conditions that will either speed up or slow down
evaporation.
● The main factors affecting the rate of drying are: temperature, air movement, humidity and
weather.
● Hot temperatures, windy conditions and low humidity are ideal for the drying of clothes.
● A sunny day is best for drying clothes.
● A clothes dryer replicates these ideal conditions by maintaining high temperatures, and low
humidity, while constantly moving the clothes around. Some clothes dryers even blow hot
air over the clothes. That is how a clothes dryer works so fast!
