Now that you have learned about Density, Boiling Point and Solubility, you will now have a chance to apply your knowledge and skills to a Water Analysis.
To begin today, we are going to revisit what we started with in this unit…a video on Why Water?
After, I am going to have you partner(or triple) read this article about Hong Kong’s water situation.
We will then come together and brainstorm a list of potential pollutants and sources of those pollutants in water around the world. As your team does this, please list them on your sheet of paper. You will be rotating from group to group adding on to each paper.
In preparation of looking at samples of water next week, we will conclude by watching this video on the PH of different liquids.
1. Read ,with a partner, the blue paper “Reading- Water is the Universal Solvent”. You will answer the question at the bottom of the reading but you may want to look at video 2 and 3 before answering.
2.. Watch this clip to learn a little more about the importance of water in our lives and why Water is the universal solvent: Add some notes about water into your science notebook.
3. Water Pollution: The Dirty Details: This video clip explains about the kinds of water pollution and how the a community and others are working to reduce the amount of pollutants going into our waterways. Gives tips for individuals to reduce their harmful impacts on surface waters. Take a few notes as you are watching this clip in your science notebook and then later add some details into your Scrapbook.
4. While most water pollution is occurring due to agricultural reasons, here is a video clip Pennsylvania Farmers Protect Water Quality to show what some farmers are doing to help protect the water in the community Record some of the way these farmers are trying to reduce water pollution.
The Pulse: Hong Kong’s Water Supply Compared with other places in the world, Hong Kong’s freshwater consumption charges aren’t really that high. Whether we actually have enough water to drink currently depends on supplies, and agreements that only run to 2014. Our pipes and water mains are often old, and Hong Kong’s leakage rate in 2011 was an astonishing 19%. So what can Hong Kong do to make itself more self reliant in future? Well, one option is desalination. Discussing alternative approaches to our water supply are Vincent Mak, a Chief Engineer with the Water Supplies Department, and Ho Man-kit of the Momentum 107 group.
The video is a full episode from RTHK on water pollution in Hong Kong. The video takes a look at one of Hong Kong’s main source of water and what is happening that may cause Hong Kong to rethink solutions for getting drinkable water.
