Young scholars research how engineers and scientists generate linear and angular measurements with geometry to survey the Earth and Mars. They assess how geometric shapes affect navigation. A surveyor comes to the classroom and explains how he surveys locations to describe the techniques he uses to show how geometry and math are used in surveying.
Students use their prior knowledge to being their examination of the water cycle. In groups, they complete an experiment in which they can see water evaporating and coming back to the ground. They discover the ocean's water evaporates and then comes back down to the ground in the form of precipatation.
Looking for an estimation activity a bit more involved than the typical "guess the number of jellybeans in the jar" game? Here, learners use a picture to estimate the number of people at a large event, look for potential problems with surveys, and use HTML codes to estimate the number of pages on the web. It can easily be adapted to accommodate other grade levels. Part of the activity requires Internet access and knowledge of Python 2.7 or Sage.
Sixth graders identify and describe the composition and physical properties of the layers of the Earth. They also explain how scientists used the scientific process to know about the center of the Earth. Finally, 6th graders read a topographic map and a geologic map for evidence provided on the maps and construct and interpret a simple scale map.
High schoolers explore the concept of surface area. In this surface area lesson, students cut out and tape together hexomino patterns. High schoolers discuss what polygons make up the faces of various hexomino 3-D objects. Students make examples of nets and non-nets using paper and tape. High schoolers discuss properties of polygons such as number of vertices, faces, and edges. Students find the surface area of their constructions.
A colorful wedge of Earth, map of tectonic plates, and numbered facts about Earth structure fill the first two pages of this resource. After reading and absorbing the information, geologists get into groups and make clay models to demonstrate faulting and folding of Earth's crust. A second activity is also included in which individuals research Pangaea, Laurasia, and Gondwana. Plenty of background information and a grading rubric are included to support you with these assignments.
Students discuss major causes of earthquakes and identify famous fault lines, access and map information about ten largest earthquakes in world from 1989 to 1998, and theorize about location of these earthquakes as they relate to Earth's tectonic plates. Students then track current quakes online for one week, and create multimedia presentation describing how and why earthquakes occur.
Students examine the geography of Utah and the Pony Express in Utah. In this Utah and Pony Express activity, students examine background information before completing mapping and art activities about the purpose and routes of the Pony Express. They determine why the service quickly became obsolete.
