Title-
|
|
|
Background-
|
| Main Fresh Water Sources Worldwide, transportation issues, regional issues with acquiring fresh water, ground water, participatory water, non-potable sea water |
| |
|
Expected Outcome Of This Lesson Plan-
|
1.Students will understand why some water is drinkable while other water is not.
2.Students will understand how much of the Earth's total water is fresh-water
3.Students will understand where the water in their house likely comes from. |
| |
|
Teacher Objectives-
|
1.Students will know that sea water makes up almost 97% of all of Earth's water.
2.Students will be able to list at least 3 sources of fresh water.
3.Students can give at least one reason why water is either scarce or abundant regionally. |

1. Lesson Introduction-
1.What do you guys already know about fresh water?
2.Fresh water is all the water in the world that isn't salt-water.
3.It comes from many places, today, I'm going to show you the main ones and what separates salt water from fresh water. (Talk Energetically, excitedly, tell story about falling glaciers in Alaska maybe; don't talk in boring scholarly way) Kris Huysken, Fredrick, Holden, |

2. Lesson Progression-
1.Here is a 3D model that illustrates all of the ideas we're going to go over today.
2.The first thing we're going to look at is this beach, people obviously can't go down to the beach and drink this water because it has salt in it. Not only does it taste bad, but it also will make you sick and more thirsty if you drink it. But this is where a lot of fresh water first comes from. Some of the ocean water evaporates when it gets hot outside, but the salt stays in the ocean because its too heavy to evaporate. Now, we have salt in the ocean and fresh water in the air (student puts water into watering can using cup to scoop it out and watering can has cloud glued to the front of it, labeled "fresh water")
3.Now that the fresh water is in a cloud, the only way it can get to us is when it rains. And this brings us to where we get fresh water from. Our first source of fresh water is water from rivers and streams. Rivers and streams come from melted snow and rain water up on top of mountains or high ground that is simply flowing downhill. All we have to do is collect the water and treat it to remove bacteria and rocks.
4. The second way we collect fresh water is from lakes. Lake Michigan is actually a huge source of freshwater for the United States. Again, the water is just collected and treated to make it clean.
5. The third way we get freshwater is through wells. Wells are places where water has collected underground. We simply dig a hole and get the water out of there.
6. For our final method of water collection, we can use springs. Have you guys ever heard of spring water, chances are, if you have a water bottle it says thats where it came from. Springs work just like rivers and streams except that they're underground. The water simply sinks into the ground and if it builds up enough preassure, it springs up in another spot further downhill.
7. The last idea we have to cover here is how water collection and transportation effects us in our region.
One important issue is cost. If you want to get lake Michigan water from here to another state, you either have to send it through a pipe: in which case, you have to pay someone to build that pipe. Or you have to put it in bottles and sell it; we sell water from lake Michigan to London in bottled form: then you have to pay someone to put it in bottles, pay someone to drive the truck and sail the ship that carries the water. It can get very expensive. But here in the area, you don't have to take the water very far, so it costs less. Although, even some very close communities use well water, because it costs them less than piping water in from lake Michigan. |

3. Guided Practice-
| 1.Students will be doing an activity where: On a sheet of paper there are all the steps involved in getting fresh water to our homes. Students will be directed to put the steps in order. |
| |
|
|
4. Student Practice-
1.On the same sheet of paper, students will be asked to write a short paragraph describing where they think their water comes from: a lake, a well, a spring, etc., why they think this, and how they think it gets from that water source, to their house.

5. Learner Accommodations-
1.For one thing, if I have any students who have a hard time paying attention, I can call their name to help me with the demonstration if I see them losing focus.
2.For the lower ability students I will check their paragraph for understanding and help all the students who didn't understand through individual instruction during our next free-learning/laptop time.

|
6. Assessment-
| 1.As I mentioned previously, I'll be reading the student's paragraphs and helping the students who didn't understand through one-on-one help, and any student who doesn't turn in their paragraph by the next day, will be asked to describe their answer to me one-on-one, also during free-time. |
| |
|
|
7. Lesson Closure-
1. We'll review the lesson about a week later. I will photograph the 3D model and ask students to describe what is going on in each photograph to help visually make the lesson more memorable.

Measuring Student Progress-
|
| 1. Unit will conclude with review and science test on topic. |
