Did you miss a day of school? Looking to get caught up?
Missing your copy of an assignment from history class?
Take a look below for some info to get back on track.
***IMPORTANT - this info is just a watered-down reminder of what we talked about in class. It is your responsibility to take part as much as possible, do the readings, look up the information and complete the assignments with detail in order to be successful.***

1. WARM UP! LET'S START THINKING ABOUT WATER SYSTEMS!
Use the knowledge you acquire from the Bill Nye episode to complete the question page below. After finishing, place your answers in the class Hand In Bin. Yes, it is worth marks. :)
2. WHAT IS WATER???
![Picture](/uploads/3/9/5/3/39532231/1430270463.png?250)
Water is the most common liquid on our planet, vital to all life forms. In spite of the chemical simplicity of the water molecule, its physical properties are quite remarkable and weird! -- and have been a major research topic for many years. Many experiments give great insight into the structure and dynamics of water, but these often require the resources of a major research laboratory. Fresh water is one of our most important resources, and when our water is polluted it is not only devastating to the environment, but also to human health.
TASK!
Spend some time getting to know the science of water by doing the reading below. As you read, create some notes and think about...
- What is a water molecule made of?
- Is water a pure substance or a mixture? Explain how you know!
- What are the three states that water can take?
- Brainstorm a list of 5 different human wants and needs related to water. How does water help make our lives better?
- Brainstorm three ways that humans have a negative impact on water resources.
- Think of two questions that you have about water. What are you curious or wondering about water at the beginning of our unit?

When finished, use the STATES OF WATER page to write and draw your thoughts.
3. MAKING WATER DRINKABLE
![Picture](/uploads/3/9/5/3/39532231/1403214.gif?300)
In Canada, we usually get our drinking water from wells, lakes or rivers. Sometimes it is pumped from these sources or stored behind dams or reservoirs. However, in nature, water often contains impurities or toxins. How is fresh water made safe for drinking?
1) Complete the reading and questions below.
2) View the video below to learn how water is made drinkable in Winnipeg, Manitoba. The video clip is more specific than the reading above. As you watch, think: what are the specific details added to the video about water treatment that are not included in the reading?
3) Working with your science group, create a chart-paper poster to show one of the major steps in the water treatment process. Your poster should:
- explain how your step works
- have a diagram to show the step visually
- show information with words (points, labels, etc) to explain what is happening in the diagram
- be readable from far away :)
Each group has a different step in the process. When finished, we will post your creations in order on the science board.

4. FRESH WATER AND SALT WATER
![Picture](/uploads/3/9/5/3/39532231/2618078.jpg?250)
Questions to ponder...
- How are fresh water and salt water different?
- What is desalination, and why is it important?
- If we can desalinate water, why don't we just create a big machine to create drinking water for all of the people of the world?

After completing the reading/questions below, view the Dr. C Density and the Floating Egg videos. Use the venn diagram to compare your knowledge on how fresh water and salt water are different, and how they are alike. You should provide 4-5 clear points for each section of your venn diagram.
