Background Information: From FOSS Pebbles, Sand, and Silt Overview: The Pebbles, Sand, and Silt Module consists of four sequential investigations, each designed to introduce concepts in earth science. The investigations provide experiences that heighten students’ awareness of rocks as earth materials and natural resources. They will come to know rocks by many names in a variety of sizes. Pebbles and sand are the same material – just different in size. Main Topics/Activities: Investigation 1: First Rocks Part 1: Three Rocks Part 2: Washing Three Rocks Part 3: First Sorting Part 4: Sorting Games Part 5: Start a Rock Collection Investigation 2: River Rocks Part 1: Screening River Rocks Part 2: River Rocks by Size Part 3: Sand and Silt Part 4: Exploring Clay Investigation 3 Part 1: Rocks in Use Part 2: Looking at Sandpaper Part 3: Sand Sculptures Part 4: Clay Beads Part 5: Making Bricks Investigation 4: Investigating Soil Part 1: Homemade Soil Part 2: Soil Search Part 3: Studying Local Soil Conservation Exploration Part 1 Natural Resources Part 2 Conservation Materials: All materials for Investigations 1-4 are included in FOSS module kit. This includes tabbed section of Investigation Duplication Masters for recording sheets, home/school connections activities, and parent communications. Materials for Conservation Exploration are attached. Extensions/Centers: At the end of each investigation section in the FOSS module teacher’s guide is a section called Interdisciplinary Extensions. These include reading, math, and art ideas, as well as further science explorations. Any of the ideas could serve as center activities; some would require a parent volunteer or teacher-recorded directions. FOSS module includes a book of Science Stories: Pebbles, Sand, and Silt. The tabbed section, Science Stories, includes ideas for using these stories to integrate reading and language skills while reinforcing science concepts. Includes directions for reading the stories, discussion questions, and ―extending the story‖ activities. The ―extending the story‖ activities make excellent science station/center activities. FOSS website at www.fossweb.com includes a Pebbles, Sand, and Silt page. Includes photo gallery of a rock quarry and a great interactive game called, ―Find Earth Materials.‖ The BrainPop website has a brief video on recycling. Appropriate for young children to introduce or reinforce lessons on conserving resources. Check out the related features on the start page. Go to http://www.brainpop.com/science/ourfragileenvironment/recycling/. The Brainpop Jr website has a video on soil. Appropriate for young children to introduce or reinforce lessons on soil. Check out the related features on the start page. Go to http://www.brainpopjr.com/science/land/soil/. Discovery Streaming Videos o Uses of Rocks and Minerals (18:00) The rocks and minerals that form within the Earth are used to make many important materials. Witness how rocks are mined, processed, and then constructed into glass, cement, bricks, houses, roads, and other objects used in our everyday lives. o Rocks: The Solid Earth Materials #1 (20:00) With the help of a Rock Wizard and a little imagination, students discover that the Earth is made up of rocks, and rocks are made of minerals. Discover the three ways rocks are formed and many of the properties of rocks and minerals—like size, shape, color, and texture. Assessment: FOSS module includes +, √, - teacher observation checklists for content knowledge and inquiry skills in tabbed sections, Assessment and Assessment Duplication Masters. FOSS module includes an end-of-module performance assessment, an end-of-module written assessment, and an end-of-module portfolio assessment checklist. All are appropriate for first graders; teacher would need to read written assessment to children. Inquiry Possibilities: Each FOSS investigation includes hands-on, structured or guided discovery activities. Other possibilities for structured, guided, or open inquiry activities are listed below. Structured Inquiry: Students are given hands-on problems to investigate as well as the procedures and materials, but are not informed of expected outcomes. Guided Inquiry Teacher provides the materials and a problem for students to investigate. Students devise their own procedure to solve the problem. Open (Student-Initiated) Inquiry – This is similar to guided inquiry, but students also formulate their own problem to investigate. o Rock Hunters Guided Inquiry on Rocks – Children can go on a rock hunt around the school, making detailed observations of rocks and developing understanding of geologic attributes. Children record their observations with drawings, words, and even quantitative measures. Find complete directions at Science NetLinks at www.sciencenetlinks.com/lessons.cfm?BenchmarkID=4&DocID=365. o Soil Sizes Structured Inquiry on Soil – Children can choose from three different activities to further understand soil. Good reinforcement of FOSS Investigations 1 and 2. Find complete directions at www.chemistry.org/portal/a/c/s/l/wondernetdisplay.html?DOC=wondernet%5 Cactivities%5Csoil%5Csoilsizes.html. o Erosion Structured Inquiry on Erosion – Children can try three different activities to understand the interaction of water and earth materials. Great extensions to FOSS Investigations 1 and 2. Find complete directions at www.chemistry.org/portal/a/c/s/l/wondernetdisplay.html?DOC=wondernet%5 Cactivities%5Cerosion%5Cerosion.html. o Water/Earth Materials Open Inquiry – Provide the rock and soil materials, containers, and screens from the FOSS lessons. Provide measuring cups, pitchers, straws, and large bins/dish tubs to allow for pouring of water. (If allowed at your school, you could conduct this investigation on the playground, using just the playground sand.) Ask children to investigate any questions they have about how water, wind, and earth materials interact. Children can form mountains, valleys, and river beds; they can pour water to simulate rivers or streams. They can explore how rivers carry water; how water and wind erode earth materials; etc. Use the attached form to help children formulate their questions, formulate their plans, and record their discoveries and answers. Careers in Science: Strand 2 History and Nature of Science, Concept 1 History of Science as Human Endeavor S2C1PO1 Give examples of how diverse people use science in daily life. S2C1PO2 Identify how diverse people and/or cultures, past and present, have made important contributions to scientific innovations (e.g., Sally Ride, Neil Armstrong). S3C2PO2 Describe how suitable tools help make better observations and measurements.
