General Lesson Information
 Lesson Plan ID: 34789 Title: Where's the Water? Overview/Annotation: The majority of Earth's surface is covered by water, but only a small percentage of this water is freshwater.  In this lesson, students will learn where saltwater and freshwater are found.  Then they will use models to show the distribution of different types of water in different reservoirs and depict this information using bar graphs and pie charts.  Finally, they will use their data as evidence to support the idea that freshwater should be conserved.This lesson was created as part of the 2016 NASA STEM Standards of Practice Project, a collaboration between the Alabama State Department of Education and NASA Marshall Space Flight Center.
Associated Standards and Objectives
Content Standard(s):
 Science SC2015 (2015) Grade: 5 15 ) Identify the distribution of freshwater and salt water on Earth (e.g., oceans, lakes, rivers, glaciers, ground water, polar ice caps) and construct a graphical representation depicting the amounts and percentages found in different reservoirs. NAEP Framework NAEP Statement:: E4.10: The supply of many Earth resources such as fuels, metals, fresh water, and farmland is limited. Humans have devised methods for extending the use of Earth resources through recycling, reuse, and renewal. Unpacked Content Scientific And Engineering Practices:Using Mathematics and Computational ThinkingCrosscutting Concepts: Scale, Proportion, and QuantityDisciplinary Core Idea: Earth's SystemsEvidence Of Student Attainment:Students: Describe and graph the amounts of salt water and fresh water in various reservoirs to provide evidence about the distribution of water on Earth.Teacher Vocabulary:Fresh water Salt water Oceans Lakes Rivers Glaciers Ground water Polar ice caps Reservoir GraphKnowledge:Students know: Nearly all of Earth's available water is in the ocean. Most fresh water is in glaciers or underground; only a tiny fraction is in streams, lakes, wetlands, and the atmosphere.Skills:Students are able to: Graph the given data (using standard units) about the amount of salt water and the amount of fresh water in each of the following reservoirs, as well as in all the reservoirs combined, to address a scientific question: Oceans. Lakes. Rivers. Glaciers. Ground water. Polar ice caps. Use the graphs of the relative amounts of total salt water and total fresh water in each of the reservoirs to describe that: The majority of water on Earth is found in the oceans. Most of the Earth's fresh water is stored in glaciers or underground. A small fraction of fresh water is found in lakes, rivers, wetlands, and the atmosphere.Understanding:Students understand that: Standard units are used to measure and describe physical quantities such as the amounts of salt water and fresh water in various reservoirs.AMSTI Resources:AMSTI Module: Dynamics of Ecosystems Alabama Alternate Achievement Standards AAS Standard: SCI.AAS.5.15- Identify the distribution of freshwater and saltwater on Earth (e.g., oceans, lakes, rivers, glaciers, ground water, polar ice caps).

Local/National Standards:

Primary Learning Objective(s):

The students will:

• use water to model the distribution of freshwater and saltwater on Earth.
• create pie charts to show the percentages of water found in different reservoirs.
• use data regarding the distribution and amount of freshwater on Earth to support water conservation.
