Field Trips
Studies that examine how geologists think and learn about the Earth point to the value of field experiences in helping students develop practices that constitute geologic reasoning. We encourage teachers to take students into the field as much as possible. The former recognizes the limitations of the K-12 classroom setting. Some places such as the seafloor are not accessible. To this end, we include ideas for virtual and actual field trips, including oceanic research expeditions. Field campaigns and oceanic expeditions provide a chance to encourage the ability to see features that are important to professional practice. Indeed, many geoscientists report that these experiences are key factors influencing their choice of geoscience as a career.

Many Planets, One Earth
Students can take a trip through the formation of Earth with this video that identifies the key conditions that make it habitable.
Scaffolding Notes
Teachers must develop their own individual plan for how they will teach the unit. The learning activities and educational resources in this unit are intended to complement other instructional activities led by the teacher. Many of the selected learning experiences provide links to excellent background preparatory materials, additional hands-on resources, teaching tips, and cross-curricular connections.
Teachers will need to create their own multimedia presentations, deliver lectures and assign ancillary work to their students in order to set the stage for effective use of the learning activities contained herein. Therefore, it is imperative to allocate time to review the activities and background material prior to using the learning experiences in this unit and to probe students for their prior knowledge before starting an activity.
In addition, although some activities may incorporate assessments, teachers may need to create their own assessments to ensure that are appropriate for the students they teach.
Asterisks (*) indicate teacher resource and background information recommendations for activity support.
_________________________________________________________
*Before beginning the activities in this unit, have students download and explore the HHMI Earthviewer app.
*As a way to become familiar with the evolution of Earth's atmosphere and to help with background information the notes and materials found at Evolution of the Atmosphere: Composition, Structure and Energy are recommended for review by teachers.
The Conditions that Support Life interactive is a narrated visualization/video that the teacher may choose to have students view by themselves, in pairs, or as a whole class, discussing different talking points at some or all of the "pauses." The teacher may decide to develop focus questions to guide their students so as to facilitate discussion. The short readings on the page below the visualization are important for clarification of key concepts and should not be overlooked. The culminating activity in this unit is an activity that refers back to the information given in this visualization.
The Shields Up! video is helpful as a review or introduction to the Earth's magnetic field, and more importantly, how the magnetic field sustains life on this planet. The teacher may decide to assign focus questions for whole class discussion or pair-share activities to ensure learner understanding.
The Goldilocks Principle: A Model of Atmospheric Gases B includes a detailed lesson plan for the teacher to implement. The teacher will need to time to prepare and collect materials prior to implementation in the classroom. The lesson includes suggestions for student assessment and modification strategies for alternative learners. The activity targets students in grades 6 - 9. One expert reviewer suggests the addition of a higher level and quantitative treatment of the greenhouse effect to support more advanced high school level learners.
The 25 Biggest Turning Points in Earth's History gives learners the opportunity to explore the biggest events in Earth's history through mini articles and accompanying videos. The teacher may decide to have students work in pairs and share, assign for homework, or create a questions or a scavenger-hunt type activity to guide students in their exploration of this resource.
The Origins of the Atmosphere reading could be assigned as a homework assignment in order to prepare students for in class discussion or as preparatory material for the subsequent learning activity, Clues to Oxygen Formation. This short video expands upon the role of banded iron formations in the formation of oxygen in Earth's early atmosphere.
*For additional detail regarding the "Great Oxygenation Event", this article from the BBC's Earth Timeline can be used by the teacher and/or the students as background information giving insight into stromatolites and the cyanobacteria that formed them.
The next learning activity, What do Banded Iron Formation Deposits Reveal about the Evolution of the Atmosphere?, comes from SERC's On the Cutting Edge collection, a repository of resources developed for undergraduate Earth science instruction. However, with careful instructor review, we recommend its use in the high school classroom. The link is a page that describes instructions for the teacher to guide learners through discussion of banded iron formations, including using magnets to examine BIF samples. The instructor then guides learners through the development of a concept sketch to assess their understanding of how BIFs give insight into the evolution of Earth's atmosphere. The teacher should complete such a sketch prior to implementing in the classroom, in order to anticipate any difficulties learners may have in developing a concept sketch.
The Life Has a History module is part of the University of California at Berkeley's Explorations Through Time series. During this tour students learn about geologic time, fossils, ancestral relationships, cladograms, variation, natural selection, and extinction. Each module includes pre and post-tests, focus questions, and answer keys.
The Methane Circus is an investigative activity developed by researchers on NOAA's Okeanos Explorer, and the link to the activity gives the teacher access to an extensive learning guide with instructions and handouts to accompany the investigation. Also a part of the CLEAN collection, this link will direct the teacher to extensive reviewer notes, teaching tips, extensions, and correlations to various literacy standards. Though the original source indicates a grade level of 5-6 for this activity, the content is rigorous and appropriate for use in the high school classroom, especially when student-driven, as opposed to teacher-led. Prior review by the teacher is suggested for successful implementation of this activity.
Mass Extinctions introduces general ideas about mass extinction and emphasizes specific extinction events in Earth's history. The activity requires that students have Internet access. More than 99% of all species that have ever lived on Earth are now extinct. The vast majority (over 95%) died out either because they could not successfully compete for food or other resources, or they failed to adapt to changes in their local environment over tens or even hundreds of millions of years. Teachers might decide to assign the reading as an in-class or outside of class activity with learners taking notes in preparation for classroom discussion about the five major extinctions and what factors lead to these mass extinctions.
NOVA Science Now: Mass Extinction engages the learner in the story of the complete reset of life evolution on our planet as it happened at the end of the Permian Period. This video could be used to encourage discussion of the effects that changes on our planet incur on life, and the possible repercussions of modern activities.
Both Weighing the Evidence for a Mass Extinction: In the Ocean and Weighing the Evidence for a Mass Extinction: On Land support HHMI's short film, The Day the Mesozoic Died. While HHMI suggests showing the film before these two activities, we recommend the learners investigate the evidence for mass extinction through these lab activities and then confirm their results through the viewing of the film. This supports the learners' use of scientific inquiry, an important pedagogical model in Earth science. Alternatively, the included PowerPoint lecture, The Rock That Changed the World, could be utilized instead of the film, as it presents an expert's discussion of the Cretaceous-Tertiary mass extinction event.
*Additionally, the following links give teachers access to supporting materials for K/T extinction activities: The Making Mass Extinctions, Blast from the Past is available as a digital image and PDF and is helpful at looking at the "big picture." The following links are to the images and explanations of the K/T cores: New Evidence of Meteorite Impact Found Beneath the Seafloor, K/T Full Core, and K/T Core Replica Notes. An additional useful teacher resource on the major discoveries and contributions from the ODP and the Joides Resolution can be found at ODP's Greatest Hits.
How Mighty Jupiter Could Have Changed Earth's Habitability is a web article that could be assigned as a homework activity to prepare for a classroom discussion regarding influences to Earth's habitability.
The TED Talk David Gallo: Life in the Deep Oceans engages the learner in what resides deep beneath the oceans' surface, the challenges for life, and the types of organisms that survive in the abyss. This prepares the learner for the subsequent learning activity, How do You Get Your Energy?. In this investigative activity, students will be collecting bacteria from two locations in the school environment and comparing their growth to create correlations to the chemosynthesis that occurs at hydrothermal vents. This lab has extensive teacher prep, creating cultures and gathering materials, so it is important that the teacher preview and plan before implementation in the classroom. The resource includes extensive teacher "tips" and preparation notes in addition to suggestions for levels of student participation.
Aterra Explorer 4: Create an Organism is intended to be a culminating activity for learners to use their knowledge of habitability to evaluate the likelihood of life on an unknown planet and in turn, create an organism with the adaptations necessary to survive in this environment. Prior preparation includes duplication of planet cards and handouts. The teacher might have learners work in pairs or groups and then share with the class their organism and its adaptations, either through presentation or "gallery walk" style.
