Fieldwork Techniques 9 - Humidity with Danielle Leggo @ Sydney Olympic Park. www.sydneyolympicpark.com.au/education_and_learning - Hi. I'm Danielle and I'm here to show you how to measure humidity. Humidity is the amount of moisture in the air. The piece of equipment you will need for that is called a hygrometer, or a wet and dry bulb thermometer -- the reason being is that we have a wet bulb and a dry bulb here.The first thing we have to do is make sure that the reservoir below our wetbulb has some water in it, and that the wick coming up and surrounding that wet bulb is wet itself. Now, we can conduct the test. We make sure that wehold it away from our body, our arm, or our hand so that we don't interact with the thermometer itself and change the results. We leave it out in the air for about two minutes and we start to take the readings. We take, first of all, the dry bulb reading. Today, the dry bulb reading is 23 degrees. We then take a reading from the wet bulb thermometer. The wet bulb thermometer today is 21 degrees. We now minus the wet bulb from the dry bulb. So, 23
minus 21 gives us a two degree difference. We have a difference column up here at the top of the hygrometer. We go to the two degrees. We work our way down until we come to the dry bulb thermometer reading. We go down the two degree difference column until we get to 23 degrees on our dry bulb, and we take the reading. That reading is 82; that means 82%. So, today our humidity in the air is 82%. That is how you measure humidity.

Water Cycle Song Lyrics:
The Water Cycle
Takes the water and moves it
Up and Down and all around the Earth
When the heat from the Sun
Warms up all the groundwater
Then it turns to water vapor
Condensation takes over
It goes up to the clouds
Water vapor cools down
And it changes to a liquid, now
When the drops get big
It falls like Rain, Snow, Sleet, and Hail upon my head
I know it's the water cycle happening again
Evaporation, Condensation, Precipitation
Learn about the role of the sea in global warming.
The global conveyer belt is part of the large-scale ocean circulation that is driven by differences in the density of the waters. It plays a key role in keeping the climate at balance and Europe warm. Global warming may change it forever with unforeseeable consequences.
Short videos, explaining things. For example Evolution, the Universe, Stock Market or controversial topics like Fracking. Because we love science.
We would love to interact more with you, our viewers to figure out what topics you want to see. If you have a suggestion for future videos or feedback, drop us a line! :)
We're a bunch of Information designers from munich, visit us on facebook or behance to say hi!
The climate change and global conveyor belt
Also: We made a brief intro for kurzgesagt videos! Tell us how what you think about it :D
Help us caption & translate this video!
Did you know that a basic understanding of the clouds can help you predict the weather? Its true. Cumulonimbus clouds are a sign of rain and cirrus clouds often indicate a change in the weather. Learn more at http://www.untamedscience.com/clouds
A brief synopsis of latitude and longitude and how they are used to accurately describe locations on the surface of the earth.
Feel free to use this video! If you do, please leave a comment and let us know how you used it.
I made this for my final project in Chemistry in 11th grade. Hope you enjoy! This video details how we understand global warming, and the chemistry behind how it affects each and every one of us.
