18.104.22.168 Surface Changes
Explain how, over time, rocks weather and combine with organic matter to form soil.
Explain how slow processes, such as water erosion, and rapid processes, such as landslides and volcanic eruptions, form features of the Earth's surface.
MN Standard in lay terms:
The Earth's landforms change over time. Change can occur quickly like an earthquake or more slowly like water erosion.
1. Waves, wind, water, and ice shape and reshape the earth's land surface by eroding rock and soil in some areas and depositing them in other areas, sometimes in seasonal layers. 4C/E1
2. Rock is composed of different combinations of minerals. Smaller rocks come from the breakage and weathering of bedrock and larger rocks. Soil is made partly from weathered rock, partly from plant remains-and also contains many living organisms. 4C/E2

Benchmarks of Science Literacy
In these years, students should accumulate more information about the physical environment, becoming familiar with the details of geological features, observing and mapping locations of hills, valleys, rivers, etc., but without elaborate classification. Students should also become adept at using magnifiers to inspect a variety of rocks and soils. The point is not to classify rigorously but to notice the variety of components.
Students should now observe elementary processes of the rock cycle-erosion, transport, and deposit. Water and sand boxes and rock tumblers can provide them with some firsthand examples. Later, they can connect the features to the processes and follow explanations of how the features came to be and still are changing. Students can build devices for demonstrating how wind and water shape the land and how forces on materials can make wrinkles, fand faults. Films of volcanic magma and ash ejection dramatize another source of buildup
Common Core Standards (i.e. connections with Math, Social Studies or Language Arts Standards):
5.2.1 Read closely to determine what the text says explicitly and to make logical inferences from it; cite specific textual evidence when writing or speaking to support conclusions drawn from the text. For example, students will read text and need to respond to it either written or verbally.
5.2.3 Analyze how and why individuals, events, and ideas develop and interact over the course of a text.
5.2.4 Interpret words and phrases as they are used in a text, including determining technical, connotative, and figurative meanings, and analyze how specific word choices shape meaning or tone.
5.2.7 Integrate and evaluate content presented in diverse media and formats, including visually and quantitatively, as well as in words. Students will use graphs, charts, tables to understand and compare results.
5.2.10 Read and comprehend complex literary and information texts independently and proficiently.
5.6.2 Write informative/explanatory texts to examine and convey complex ideas and information clearly and accurately through the effective selection, organization, and analysis of content.

5.6.8 Gather relevant information from multiple print and digital sources, assess the credibility and accuracy of each source, and integrate the information while avoicing plagiarism.
5.6.10 Write routinely over extended time frames (time for research, reflection and revision) and shorter time frames (a single setting or a day or two) for a range or tasks, purposes, and audiences. Science notebooks would provide the opportunity to meet this standard.
5.8.2 Integrate and evaluate information presented in diverse media and formats, including visually, quantitatively and orally. During science digital media such as webquests, videos are used to help explain a concept, students also are presented with information orally and through experiments in which quantitative data is used to make a point.

- Water cannot wear away solid rock
- Wind and water cannot wear away solid rock to change the path of a river
- Water cannot carry rocks and deposit them in a new location
- Landforms look similar today as they did many millions of years ago. For example, a river on earth today hasn't changed over time
- Water that freezes in cracks in rock cannot break the rock
- Wind and water cannot wear away the solid rock of a mountain.
- Earthquakes are often thought to be only destructive, however, earthquakes are also building landforms.
- Soil and dirt are the same thing.
- Volcanoes are often thought to have only violent eruptions, however, some volcanoes act more like streams of molten lava flowing over the side of the volcano creating land.
- Streams are simply flowing water (with little to no concept of sediment movement).
- Idea that human activities cannot affect geological processes like river flow, flood cycles, etc.
- Most of following are tied to general idea of 'stasis', the idea that the Earth's surface and geological processes do not fundamentally change over time.
- Floods are rare, atypical, almost unnatural events rather than normal river behavior.
In Mrs. H's science class the students work in cooperative groups to work with stream tables to discover how water erodes earth material and makes changes to the earth's surface. Students work with stream tables, earth material,(sand, clay, diatomatious earth) and water to discover how water moves through the earth material eroding and causing change in the landscape. Pictures of streams, the Grand Canyon, other waterways would be posted or shown on a smart board/projector for students to observe and discuss. Mrs. H poses these possible questions to the students, "Why does the stream flow in the direction it does?" "Why do we often see bends or meanders in the stream/river?" "What else do you notice about the water and land?" Students would record their thoughts into their science notebooks and then continue on with the procedures for setting up the stream table.
The cooperative groups work together to set up their stream tables and each group is checked for appropriate set up by Mrs. H. Students begin by observing a slow flow of water through the stream table, using a quart container with a small hole drilled into the bottom. They use timers and record when key events happen so they can later compare the "slow flow" to a "flood flow". They should be noticing that the particles in the earth material are not all the same, (sand, clay, silt) they vary in color and in size. When the container of water is depleted Mrs. H asks the class to make some additional observations and to draw a diagram of their stream table into their science notebook indicating the different particle sizes by using different colors to identify the different materials. Then Mrs. H asks the class some questions which might include..."Which particles moved the furthest away from the earth materials? Why?" "What might have caused the meander in the water-way?"
Use the stream table to come up with a definition for the word "erosion",discuss as a class and agree on a definition that is suitable. You could also introduce the word "deposition" at this time.
Mrs. H then continues the lesson the following day and uses a flood source (quart container with a larger hole drilled into the bottom) to compare the erosion results. Again, students time key events, draw a diagram so they are able to compare the two investigations.
As a possible extension Mrs. H. then challenges the class to come up with designing a community in the stream table, each group must have at least 10 homes in the community, they are given a budget to "purchase" items to help stop erosion, plants, craft sticks, aluminum foil, plastic, paper bags, straws-just about anything you can find in a classroom. When the group is finished planning their community, purchasing their supplies from the "store" they then construct their stream table and test it by running water through the stream table. Once the water is completely through, they then look for damages and deduct given amounts of money for any damaged property. Homes that are not damaged earn the group money. The groups compete to see who can earn the most "money" from the "sale" of homes. They continue the study of the earth's structure by exploring the quickly changing forces that occur within earth's system.
Essential Questions for this vignette:
- What happens when water flows over earth materials
- What happens to the earth materials eroded by water?
- How does the size of a particle affect deposition?
Benchmark 18.104.22.168.1 What makes soil? Learning about Our Local Soils. In this activity, soil samples will be taken from students' home sites and brought to school. Students will make and record observations of their soil samples in their journals. Students will come up with ways of "sorting" the components of their sample to determine what their samples are made of. Students will test their sorting strategies. Students will revise their original journal entries. Students will share their findings with the group. The teacher will begin teaching a unit on soil based on ideas from a unit developed by Utah Agriculture in the Classroom from the Utah State University Extension called, Dirt: Secrets in the Soil. I would use this after students have shown understanding of erosion.
Benchmark 22.214.171.124.1 The Dirt on Soil Through hands-on exploration, students will learn about three basic soil types and some of their physical properties. Extention-Concepts of porosity and permeability will be developed through experimentation. Students will design and implement a model of a water treatment plant.

Benchmark 22.214.171.124.2 Snack tectonics Students learn how Earth's tectonic plates (lithosphere) ride atop the slow flowing asthenosphere layer. Students understand how plates interact at their boundaries. A very simple activity but the concept of becomes very clear and memorable for students.
Benchmark 126.96.36.199.2.Students will conduct a series of experiments in pairs through which they will explore the processes and effects of weathering and erosion. Using the results from these explorations, they will design and conduct an experiment comparing the rate of erosion in different biomes. This activity not only allows students to learn about weathering and erosion, but also illustrates how scientists often use the results of one experiment to inspire another and/or use initial observations to inform a hypothesis.
An extensive collection of best practice techniques that could be used in any classroom setting.
Science notebooking is a way to teach students how to record data in a clear and precise way. The students will take ownership in their work and be able to share their data with others. It also allows an experiment to be retested based on the information that the student recorded. FOSS Science Notebooking

1. Explain how the process of sandblasting (for example, machines blow sand at surfaces like a painted house to strip the paint off) is like the natural process of wind erosion? (analysis)
Sandblasting and wind erosion can be compared because they are both breaking down the surfaces by sand hitting it, sandblasting happens with more force and speed so it happens faster than erosion, but the concept is similar because they both are breaking down the surfaces of the rock and the paint.
2. Why would California have more earthquakes than Minnesota? (knowledge)
California is on top of two plates, Minnesota isn't. In order to have an earthquake two plates need to move.
3. Illustrate and explain how soil forms. (comprehension and analysis)
Verify that they have included various particles (organic matter, air, water and rocks)
4. How might you build a building to withstand an earthquake?-this could support an engineering standard.

Struggling and At-Risk:
The suggestions given on the website for Special Education Students would also apply here.
Additional exposure or pre-exposure to activities can be helpful. Build cooperative learning groups carefully. Students must be grouped with students who will allow them to participate and use their strengths. Adapted from: Supporting Special Education Students in Science
What Should a Science Curriculum for Gifted Students Include?
At the Center for Gifted Education at the College of William and Mary, the past six years has been spent addressing issues of appropriate science curriculum and instruction for high ability students as well as melding those ideas to the template of curriculum reform for all students in science. Consequently, the elements essential for high ability learners also have saliency for other learners as well. The most important include the following elements:
An Emphasis on Learning Concepts. By restructuring science curriculum to emphasize those ideas deemed most appropriate for students to know and grounded in the view of the disciplines held by practicing scientists, we allow students to learn at deeper levels the fundamental ideas central to understanding and doing science in the real world. Concepts such as systems, change, reductionism, and scale all provide an important scaffold for learning about the core ideas of science that do not change, although the specific applications taught about them may.
An Emphasis on Higher-Level Thinking. Students need to learn about important science concepts and also to manipulate those concepts in complex ways. Having students analyze the relationship between real world problems, like an acid spill on the highway, and the implications of that incident for understanding science and for seeing the connections between science and society provides opportunities for both critical and creative thinking within a problem-based episode.
An Emphasis on Inquiry, Especially Problem-Based Learning. The more that students can construct their understanding about science for themselves, the better able they will be to encounter new situations and apply appropriate scientific processes to them. Through guided questions by the teacher, collaborative dialogue and discussion with peers, and individual exploration of key questions, students can grow in the development of valuable habits of mind found among scientists, such as skepticism, objectivity, and curiosity (VanTassel-Baska, Gallagher, Bailey, & Sher, 1993).
An Emphasis on the Use of Technology as a Learning Tool. The use of technology to teach science offers some exciting possibilities for connecting students to real world opportunities. Access to the world of scientific papers through CD-ROM databases offers new avenues for exploration. Internet access provides teachers wonderful connections to well-constructed units of study in science as well as ideas for teaching key concepts, and e-mail allows students to communicate directly with scientists and other students around the world on questions related to their research projects.
An Emphasis on Learning the Scientific Process, Using Experimental Design Procedures. One of the realities we have uncovered is how little students know about experimental design and its related processes. Typically, basal texts will offer canned experiments where students follow the steps to a preordained conclusion. Rarely are they encouraged to design their own experiments. Such original work in science would require them to read and discuss a particular topic of interest, come up with a problem about that topic to be tested, and then follow through in a reiterative fashion with appropriate procedures, further discussion, a reanalysis of the problem, and communication of findings to a relevant audience.
