3 Water Usage Log Instructions How do you use water? How much do you consume in a week? You will be tracking your water usage for one whole week. You will need to calculate the flow rate of some of the taps you get water from. (Ex. Water fountains at school, bathroom sinks where you wash your hands, kitchen sink where you wash vegetables.) ANY TAP YOU RUN WHERE THE WATER RUNS DOWN THE DRAIN. Other times you will fill a 1L bottle with water so you already know the total and you don t need a flowrate. Find your flowrate in L/s. This will help you to calculate how much water you are using every time you wash your hands or run the tap. FR = V_ t Sometimes you can find the flowrate for your shower head or a reasonable estimate can be found in an internet search. This might be a better way to calculate the water used in the shower. (For a shower, it is best to find the flowarate in L/min) Other devices, like a washing machine or a dishwasher are harder to calculate flowrate for. You can look up how much water is used for your dishwasher each load or find a rough estimate on the websites provided on Mrs. van Beek s website. You should consider your own personal usage. So if your family runs the dishwasher 8 times a week and you are a family of 4. Consider that 2 of those dishwasher loads were for your needs. If your family does 10 loads of laundry in a week and you are a family of 4 consider that 2.5 loads are yours. You may record your log by hand on the sheets provided, but a more impressive way to present this would be in google Sheets where all your calculations have been shown. (An example will be shown in class.) You can also break down your weekly usage into major categories: Bathing, Toilet Flushing, Laundry, Showers, Washing Hands etc. Create a Pie Graph to show the breakdown. Use of colour will also be impressive. Marks will be rewarded based on how thoroughly you collect data, how you organize it, use of calculations in Google Sheets and use of colour and legends to explain your data. Be creative and have fun! 2 pages have been provided for you to keep track of your water usage. You may choose to keep track in a different way. They are there for you to use as you see fit. Submit all Google Sheets trough Google Classroom. Additional resources for this part of the assignment are also available on Google Classroom.

4 (5) Track your water usage for the next week. Write down when you use water and for what purpose. How long you use the water is also important; it ll tell you how much you use. DATE TIME ACTIVITY

6 Chapter 10 Safe Drinking Water Describe a water particle: Diagram of water in its three states: Label the water cycle diagram: Describe how the states of water and changes of state affect the environment:

7 Add labels to the water table diagram: Complete the pie chart to show the distribution of water on Earth: State of Water Percent of Total Convert to Degrees Salt Water 97.0 (x 3.6) Fresh Water - Solid (Ice) 2.5 (x 3.6) - Liquid 0.4 (x 3.6) Degrees - Gaseous 0.1 (x 3.6) 360º

8 Label the seven steps of the water treatment process diagram: What Did You Learn? Try these questions: Indicate whether each statement is true or false. If the statement is false, change the statement to make it true. A particle of water contains one particle of hydrogen and two particles of oxygen. The energy to drive the water cycle comes from within Earth. Freezing and condensation involve the loss of thermal energy.

9 Which of the following processes involves water particles gaining thermal energy? (a) freezing (c) sublimation (b) deposition (d) condensation Which substances can be destroyed or eliminated from water using UV treatment? (a) salts (c) bacteria and viruses (b) sediment (d) calcium and magnesium Which of these is typically the last step in water treatment? (a) filtering through a screen (c) filtering through sand and charcoal (b) adding chlorine to kill bacteria (d) adding alum to make sediment stick together How is reverse osmosis different from filtration? How are the processes similar? Describe three of the changes of state that water can undergo in the environment, and identify where on Earth each change might occur. The water contamination crisis in Kashechewan, Ontario, has been but one example of a Canadian community that has been affected by problems with their water supply. How would you be impacted if our water supply was jeopardized in the same way?

10 Chapter 11 Water Quality Create a concept map for the contaminants in water: Testing Water Quality list and describe what we test to be sure of our water quality:

11 Describe how the continental divide affects the flow of water: Label the diagram (right) to show the flow of water from the continental divide to the oceans: What is a watershed? Label the steps in the wastewater treatment process diagram:

12 What Did You Learn? Try these questions: Indicate whether each statement is true or false. If the statement is false, change the statement to make it true. Salinity is a measure of the amount of salt dissolved in water. Bioremediation involves using chemical reactions and filters to remove contaminants from water. About 97 % of the water on Earth is salty and cannot be used for drinking. Match each term in the left column with the best example in the right column. chemical contaminant (a) a factory releasing hot water into a lake biological contaminant (b) road salt used in the winter thermal pollution (c) wastes from chickens and other livestock Which of the following is an example of a biological contaminant? (a) acid (b) nitrates (c) parasites (d) sediment A scientist measures and records the concentration of salt in a solution. Which of the following could be the scientist s measurement? (a) 30 g (b) 30 g/l (c) 30 L (d) 30 % Which of the following scenarios is an example of bioremediation: (a) chlorine being added to treated wastewater to kill bacteria (b) pesticides being applied to a farm field to kill harmful organisms (c) organisms in a wetland consuming nutrients in stormwater runoff (d) solid wastes settling out of a mixture of blackwater and greywater The city of Vancouver is in the Pacific Ocean watershed. Which of the following statements best explains what this means? (a) All the water in Vancouver comes from the Pacific Ocean. (b) Precipitation that falls on Vancouver also falls on the Pacific Ocean. (c) Surface water in Vancouver ultimately ends up in the Pacific Ocean. (d) Water that falls on Vancouver has evaporated only from the Pacific Ocean.

13 Which of the following steps in sewage treatment occurs after the wastewater passes through the grit tank and before it passes through the clarifier? (a) Chlorine is added to kill bacteria. (b) A bar screen removes large objects. (c) Micro-organisms break down organic matter. (d) Treated water is released into surface water bodies. Describe the watershed in our area. Where does the water flow in the region around Barrhaven and Ottawa? What main waterways are there? _ Imagine that you have been asked to assess the water quality in a nearby stream. Describe three tests you would use to do this. For each test, describe the tools you would use and identify the results that would indicate poor water quality.

14 Chapter 12 Water, Weather and Climate What Did You Learn Try these questions: Indicate whether each statement is true or false. If the statement is false, change the statement to make it true. Weather is the average environmental conditions for an area over the last 30 years. Areas near large bodies of water tend to have milder climates than inland areas. Flash floods occur along coastlines when hurricanes come ashore. Which of the following situations is most likely to cause a flash flood? (a) a hurricane moving toward a coastal area (b) seasonal rains falling along a river valley (c) the ice on a lake beginning to melt in the spring (d) a storm developing suddenly and remaining in one area City A and city B are located at approximately the same latitude. City A is very close to the ocean. City B is far inland. Which of the following statements about the two cities is most likely true? (a) City B receives less snow in the winter than city A. (b) City B receives less energy from the Sun than city A. (c) City A has warmer summers and cooler winters than city B. (d) City A has cooler summers and warmer winters than city B. A student fills four cups with different materials at the same initial temperature (Table 1). Table 1 Cup A B C D Filled with soil clay water sand She places the bulb of a thermometer just below the surface in each material. She shines a heat lamp on each material for 10 minutes. In which cup will the thermometer probably have the lowest temperature reading after 10 minutes? (a) cup A (b) cup B (c) cup C (d) cup D
