Organization of the Text Set
Introduction Day 1: The videos and texts are organized for the student. In the introduction phases of the lessons the links are on the page for whole group, small group, or individual instruction. (please reference the documents below)
Research in Library Day 2-4: The texts are arranged in categories based on the question they are working on. Each student is doing choosing some texts to read . Each student is answering every question. Then they are collaborating their gathered evidence and making a presentation to the class.(please reference the documents below)
Text Sequence for Lesson/Unit | Learning Objectives |
1.Introduction with 3 video clips | To introduce problems with water. i.e. Why is it a human right to have access to clean water?; the importance of fresh water; drought in California. |
2.Map reading | To discover the limited amount of fresh water on Earth, what is happening in aquifers. Introduce students on how read graphic information. |
3.Humans and Water Use | Where are the sources of fresh water found?; what are the major demands of fresh water; explain the supply/demand of fresh water? |
4.Freshwater crisis | Look at the inefficiency of food production; i.e. hamburger. Make a correlation of population growth and freshwater demand. Students will discover water stressed regions. |
5.National Geographic | To discover and understand how rivers are at risk, the issue of diminishing groundwater, climate change and how agriculture/residential/industry are affecting water pollution. |
6.Taking the Water Footprint Quiz or Freshwater 101 Quiz | Students discover their water comsumption or test their knowledge of water resources. |

Student Tasks
- What are the data charts or graphs telling you?
- What are the toxins or cause of water ecosystem changes?
- Describe how these activities are contaminating our freshwater.
Formative Assessment:
- Students take the Freshwater Quiz 101 (preferred) or "What is your Water Footprint?"
- Discuss results in class and clarify major points.
Summative Assessment:
- Students will make a collaborative Google Docs presentation that will be assessed by teacher for critical thinking skills. (See Rubric below).
The summative assessment of this assignment was the group presentation which was graded upon the rubric. See rubric below.
Day 1 Work in class in small groups (2-3) to do the Introduction with video clips, Map Reading, Human Appropriation of the World's Fresh Water Supply, Freshwater Crisis, National Geographic, and Water Footprint Quiz or Freshwater 101 Quiz. The student will complete individual homework for work not completed in class. 45 minutes in class plus 20 minutes for homework.
Day 2- 4 Students will work in groups of 2-3 to research their five essential questions in one of the three category case studies: Agriculture, Residential, Industry. 45 minutes each day in the school library.
Day 5-6: Presentations and Discussions
Pre-Requisite Learning
- Students previously learned about the water cycle.
- Students previously learned about humans influencing global climate change and animal extinction dangers through the World Wide Fund for Nature (WWF) app.
- Students had formal assessments on the cycles in the ecology unit. Class discussions on water as a precious resource were conducted after students viewed video clips of water scarcity. Students previously researched animals and how their environment was impacted on the World Wide Fund for Nature app.
- Through class discussions and the previous assignments, students indicated they had limited knowledge of water as a scarce resource and they were surprised the human impact on water sustainability.
- How will we use pre assessment data to revise our teaching and challenge students at an appropriate level? A realization that we needed to be more clear about what specific items to be looking for. Students were unsure what was real "research" was. Students were not aware that data/numbers derived from data charts should be included in their analysis.
First as a class, we viewed the video clips and the map and had some informal discussion questions. Next each student was given a copy of the document and using Edmodo they opened the document electronically to access the web links. Individually each student answered questions on three separate background readings in class. Unfinished work was assigned as homework. For the next three days, students conducted research in the library using the web links for each case study or they could choose other appropriate sites. Each individual student used the document and reviewed the text. Students broke into groups of 2-3 students. Each group was assigned one of three categories to research. Students shared sources using Noodletools and then created a Works Cited page which was then shared with their teacher. Students worked collaboratively to analyze the causes of contamination and provide some possible solutions. Students used Google Drive to create one presentation which was shared with the group. The five essential questions including solutions were presented in a Google Slide presentation.
Students were given additional days outside of the library to complete the assignment, but very few needed the extra time.
We followed up by conducting freshwater studies on local pond water.
Organized Instructional Activities
INQUIRY COMPONENT:
- Students will ask questions and define problems in their small groups as they relate to their category (Agriculture, Residential, Industry).
- Students will construct explanations and design solutions to help preserve water resources and/or increase water quality.
- To increase the level of inquiry change the groups from 2-3 to an individual student researching the category.

Day 5 Student Presentations 45minutes.
Teacher assigned groups enabled students with below grade level reading ability to learn from their peers.
On the days students were in the library, the teacher and the librarian were available to assist students. The teacher individually worked with students who needed direct instruction. Only one student was ELL and had no difficulties.
