1 Pebbles, Sand and Silt Storyline Prepared Graduate Competency Evaluate evidence that Earth s geopshere, atmosphere, hydrosphere and biosphere interact as a complex system. Big Idea Earth is a system that is made up of land, water, air and living organisms. Parts of the earth change as they interact with each other. Some of these changes can happen quickly and some take a very long time. Enduring Understandings and Grade Level Expectations Earth s materials can be broken down and/or combined into different materials such as rocks, minerals, rock cycle, formation of soil, and sand of which are useable resources for human activity. Rocks are the solid materials of the earth, and can be sorted according to their properties. Rocks can be found in different sizes. Earth materials are natural resources and can be used in a variety of constructions. Soil is made of a combination of materials, including different-sized particles of rock and humus. Essential Questions What are some of the ways that Earth s materials are formed? Where do these different materials such as soil, sand, rocks and oil come from? What is the process by which the materials were formed? How is Earth s surface changing? How do rocks cycle?

2 Investigation 1: First Rocks Three Rocks Washing 3 Rocks First Sorting Part Four: Sorting Games Part Five: Start a Rock Collection How are rocks different? What happens when rocks rub together? What happens when rocks are washed? How are some rocks the same? How many ways can rocks be sorted? What rocks can we find around us? Science Stories: Exploring Rocks & Colorful Rocks Rocks have a variety of properties. When rocks rub together, some (softer) rocks may be chipped or scratched, or make rock dust. Rocks have a variety of properties. When rocks are washed in water, the colors or sparkling qualities are enhanced. Rocks can be sorted by their properties. Rocks can be sorted by their properties. Rocks are all around us. Rocks are the solid material of the earth.

3 Investigation 2: River Rocks Screening River Rocks River Rocks by Size Sand and Silt + 20 min the next day Part Four: Exploring Clay 1-2 days How can rocks be sorted by size? How else can rocks be sorted by size? Is there an earth material smaller than sand? Is there an earth material smaller than silt? The Story of Sand Peter and the Rocks Screens can be used to sort the sizes of earth materials. Rock sizes include sand, small gravel, large gravel, pebbles and large pebbles. Rocks can be categorized visually by size. Rock sizes include sand, small gravel, large gravel, pebbles, and large pebbles. Rocks larger than pebbles are cobbles. Sand often contains smaller particles, called silt. Water can be used to sort the sizes of earth materials. Clay particles are very small, even smaller than silt. Math Extension Problem A, pg. 30 Math Extension Problem B, pg. 31 Rocks larger than cobbles are pebbles. Math Standard: 3.1a.i. Organize, represent, and interpret data with up to three categories. 1.1c.ii. Identify coins and find value of a collection of 2 coins

4 Investigation 3: Using Rocks Rocks in Use Looking at Sandpaper min per student group Sand Sculptures Part Four: Clay Beads + 20 min another day Part Five: Making Bricks 20 min per student group + 30 min when bricks are dry How do people use earth materials? What does sand do for sand paper? How else can sand be used? What can be made with clay? How are bricks made? Rocks Move Making Things with Rocks Earth materials are natural resources. Earth materials are commonly used in the construction of buildings and streets. Different sizes of sand are used in sand paper to change the surface of wood from rough to smooth. Earth materials are used to make sculptures. Earth materials are used to make jewelry and sculptures. Simple bricks are made by combining clay soil with plant material. Math Extension Problems A and B, pg. 30 and 31 Math Standard: 1.2a.i. Use addition and subtraction within 20 to solve word problems

5 Investigation 4: Soil Explorations Homemade Soil 2-3 days Soil Search 1-2 days Studying Local Soil 2 days What is in dirt? Are all soils the same? How do soils differ? What Is in Soil? Testing Soil & Fossils L Soil is a mixture of earth materials. Humus is decayed material from plants and animals. The ingredients of soil can be observed by mixing soil with water, shaking it, and letting it settle. Soils vary from place to place. Soils have properties of color and texture. Different soils differ in their ability to support plants. Soils can be composed of humus and different amounts and sizes of rocks. Math Extension, pg. 26 Math Standard: 1.2a.i. Use addition and subtraction within 20 to solve word problems
