In this activity, students explore the effect of chemical erosion on statues and monuments. They use chalk to see what happens when limestone is placed in liquids with different pH values. They also learn several things that engineers are doing to reduce the effects of acid rain.
This resource is for teachers to develop their knowledge around climate science along with NGSS-aligned teaching strategies . Teachers can learn more about the following climate change impacts: coastal hazards, fire, human health, floods & droughts, agriculture and species & ecosystems. Users should reference the "STEM Seminar Slides_Template" as a guide for a daylong training and use the other materials as supplemental information and resources.
Phenomena: Flooded SchoolyardStorylineThis photograph was taken at an elementary school in Maryland after a severe Summer rainstorm. The students are concerned about the impact of the increased rainfall in such a short period of time.PE Alignment:4-ESS2-1. Make observations and/or measurements to provide evidence of the effects of weathering or the rate of erosion by water, ice, wind or vegetation.4-ESS3-2. Generate and compare multiple solutions to reduce the impacts of natural Earth processes on humans.

This lesson introduces and describes the main types of erosion (i.e., chemical, water, wind, glacier and temperature). Students learn examples of each type of erosion and discuss how erosion changes the surface of the Earth. Students also learn why engineers need to be aware of the different types of erosion in order to protect structures and landmarks from the damaging effects erosion can cause. Figure 1 is an excellent illustration of water erosion.
Students are briefly introduced to Maxwell's equations and their significance to phenomena associated with electricity and magnetism. Basic concepts such as current, electricity and field lines are covered and reinforced. Through multiple topics and activities, students see how electricity and magnetism are interrelated.
In this lesson, students will learn what erosion is and how human actions influence erosion. Includes introduction, demonstration instructions, and questions for wrap-up discussion.
Time: 55 minutes
Materials: plastic containers with sand and gravel, sponges, and plastic cups
This hands-on activity explores five different forms of erosion (chemical, water, wind, glacier and temperature). Students rotate through stations and model each type of erosion on rocks, soils and minerals. The students record their observations and discuss the effects of erosion on the Earth's landscape. Students learn about how engineers are involved in the protection of landscapes and structures from erosion. Math problems are included to help students think about the effects of erosion in real-world scenarios.
Students learn about landslides, discovering that there are different types of landslides that occur at different speeds from very slow to very quick. All landslides are the result of gravity, friction and the materials involved. Both natural and human-made factors contribute to landslides. Students learn what makes landslides dangerous and what engineers are doing to prevent and avoid landslides.
My group and I worked on discussing the flooding of the Ohio river in Cincinnati. The past few years there has been a spike in the flooding that has effect the river front of both downtown Cincinnati and on the other side of the river in Newport and Covington Kentucky. We met with a meteorologist to talk about the weather cycle and what is happening with the flooding. We thought that if we were in a real classroom we could talk about erosion and the issues that come when there is excessive flooding or the use of levees in helping to alleviate the flooding from the city.
What we see on Earth’s surface is a complex and dynamic set of interconnected systems that include the geosphere, hydrosphere, atmosphere, cryosphere and biosphere. Earth’s processes are the result of energy flow and matter cycling within and among these systems. Understanding Earth’s systems is important for many decisions made in communities today such as where to build a road, where a salmon can successfully build a redd to lay eggs, and how to ensure air quality. Erosion involves all five spheres giving students an excellent example of the interconnectedness of these large systems. Students may begin the storyline by hearing a story about the relationship between the land and plants from an Indigenous perspective, a local tribe elder or expert if possible. This perspective can be woven throughout the storyline while students explore different types of erosion: wind, water and ice in sand and soil. For real life experiences, students visit their schoolyard or nearby area to find examples of erosion. They may find examples from very small to larger examples of places where soil has eroded. They may find places where human foot traffic has made pathways through a previously planted area.
Last year the Siuslaw 97J School District changed our food service operation from a national supplier (Chartwell’s) to in-house food service. Our Food Service Manager instituted an organic philosophy and wanted to source local produce. Utilizing our school garden program we now help supply fresh produce for our Siuslaw Elementary School cafeteria. Crop production is stronger in the 4/5 wing because of wind protection from the building. Florence experiences high winds and we are located close to the beach so we have constant sand blowing into our crops. The K-3 garden beds do not have the same protection as the 4/5 beds, and as a result have a lower yield. Our goal is to have students design and engineer wind barriers for these beds and then present the best solutions to our school board so that we can get funding to implement our ideas. This project can be used in any school with a garden by using preexisting barriers on a the school property. The unique environment of the school would dictate the lessons required to be adapted to fit the environmental needs of the community. If the school is lacking a garden, the students can focus on an at home garden project.
This is a mapping activity that uses the student’s schoolyard to investigate how rain/stormwater interacts with different surfaces and where stormwater problems may occur. Students use Next Generation Science Standards’ Science and Engineering Practices in a near-by, relevant place.
In this lesson, students learn about major landforms (e.g., mountains, rivers, plains, valleys, canyons and plateaus) and how they occur on the Earth's surface. They learn about the civil and geotechnical engineering applications of geology and landforms, including the design of transportation systems, mining, mapping and measuring natural hazards.
