Inquiry Science Lesson Plan 

Reflection #4

Subject/Gr: Science (Gr.7/8)    Lesson Title: Water Distribution and the Water Cycle

Teacher: Lila Gaertner

Stage 1: Identify Desired Results
Outcome(s)/Indicator(s)/Treaty Outcomes and Indicators:

WS8.1 Analyze the impact of natural and human-induced changes to the characteristics and distribution of water in local, regional, and national ecosystems.

e. Construct a written, visual, or dramatic representation of the water cycle, including showing or explaining how a single particle of water can travel through the cycle over extended periods of time.

Modified Indicator:

e. Construct a written, visual, or dramatic representation of the water cycle. Explain or show how a single particle of water can travel through the cycle. Predict what can happen if this water cycle gets polluted.

Key Understandings: (I Can Statements)

* Construct a written, visual, or dramatic representation of the water cycle.

* Explain or show how a single particle of water can travel through the cycle.

* Predict what can happen if this water cycle gets polluted.

Essential Questions:

 What is the world distribution of water?

What is the water cycle?

Why do we need the water cycle?

Why is having clean water important?

Stage 2: Determine Evidence for Assessing Learning
 –          Once I am done the teaching part of the lesson, the students will either be working by themselves, in pairs or small groups of three where they will create a written, visual, or dramatic representation of the water cycle.

–          They will be marked on their participation in this activity and understanding of the water cycle. They will be marked on how they are able to carry their understandings into practice by creating a representation of the water cycle.

Stage 3: Build Learning Plan
Set (Warm-up, Focusing the learning):      Time: 3-5 mins

Open by saying there will be an assignment due at the end of class, so please pay close attention. Take notes if you need to.

 Ask an opening question:

Why is water important?

Water is an important part of our earth because it is used for drinking, washing dishes and clothes, provides growth, transport, and is a habitat for many types of animals including ones that we eat (ex. fish). Without water, sustainability can not be maintained.

Sustainability – is the ability to continue a defined behavior indefinitely.

Environmental Sustainability – is the ability to maintain rates of renewable resource harvest, pollution creation, and non-renewable resource depletion that can be continued indefinitely.

Development:                                              Time: 30-35 mins

Power Point Presentation (15 mins)

 What is water distribution?

Water distribution is the process of bringing water to consumers. It takes a number of forms around the world from pressurized municipal water that delivers water directly into homes to traveling tanker trunks that distribute water to community access points. Distribution of water resources is usually overseen by a government agency, although private utilities may also be involved.

What is the world’s water distribution?

The distribution of water on the Earth’s surface is extremely uneven.

Total: 97% salt water, 3% freshwater.

Freshwater: 70% glaciers, 29 % aquifers, 1% lakes, rivers, streams.

Aquifers are rocks that hold water in its pores.

Looked at another way, only 1% of the water on the Earth’s surface is usable by humans, and 99% of the usable quantity is situated underground.

What is the water cycle?

– It is the cycle of processes by which water circulates between the earth’s oceans, atmosphere, and land, involving precipitation as rain, sleet, hail, and snow, drainage in streams and rivers, and return to the atmosphere by evaporation and transpiration. Infiltration is to pass through.

Watch The Water Cycle Video – https://www.youtube.com/watch?v=0_c0ZzZfC8c

As we watch this video, watch for evaporation, water storage in the atmosphere, precipitation, water storage as groundwater, water drainage or runoff in streams and rivers back to the ocean, and then the water returning to the atmosphere by evaporation and transpiration.

Transpiration is the process where plants absorb water through the roots and then give off water vapor through pores in their leaves. An example of transpiration is when a plant absorbs water in its roots.

Why do we need the water cycle?

We need water to survive, since we on average are 50-65% made of water. If it wasn’t a cycle anymore, we would be in trouble. Because it would affect ecosystems drastically. Plants and animals need the water cycle to survive too.

What would happen if our water cycle was polluted?

Water would not be great to drink, it could damage the different species in our ecosystem or even kill them, it would take longer to clean the water enough, so that we would be able to use it and drink it.

Why is having clean water important?

We need it to drink, cook, clean our clothes and our homes.

 Work on creating representations of the water cycle (15-20 mins)

Give the students 15-20 minutes to create their written, visual, or dramatized representations of the water cycle.

Dramatized Representations (3-5 mins)

If any students chose to do a dramatized representation of the water cycle, the students must present at this point.

Learning Closure:                                              Time: 2 mins

Get the class’ attention and get them to participate in the closing discussion.

Ask: What did you learn about the water cycle today?

Do you have a greater appreciation for water now that you know how important it is to you, others around you, different species, and the ecosystems around you?

Make sure those who either did a written or visual representation of the water cycle hand in their assignments before they leave the class.

Materials/Equipment:

–          PowerPoint Presentation on Water Distribution and the Water Cycle.

Management Strategies:

–          Explain to the students that it is important to be actively listening to instructions and following them in class.

–          If the students are too loud, get their attention by clapping a pattern that they are supposed to repeat. Repeat the pattern until they are all quiet. Then continue with the lesson.

–          Ask for respect and their attention if students are too loud. Wait until they settle down.

Safety Considerations:

–          Make sure the students are aware of their personal space and their movements/actions while others are close to them.

–          Students must work together as a team to complete the assignment.

Possible Adaptations/ Differentiation:

–          Students are able to work by themselves, in pairs, or in a group of three to complete the representation of the water cycle.

–          Students are able to make a representation in either written, visual, or dramatized form.
