Earth’s Changing Atmosphere: Human Impacts and Climate Change
Topic Keyword(s):
Human Activity & Impacts
Weather & Climate
Guiding Question(s):
- In what ways is Global Warming affecting temperatures in different parts of the globe?
- Is Global Warming affecting different parts of the globe in the same way?
- What is the connection between air temperature and ocean temperature?
Placement in Curriculum: I use this to introduce a unit on climate change called “Earth’s Changing Atmosphere”. This helps ground the students in the human impacts of climate change even as we dive into the science. No prior background on climate science is required.
Learning Objectives:
Earth’s Changing Atmosphere: Life on Earth relies on a fragile atmosphere, which is being altered by human-induced greenhouse gasses, resulting in global climate changes.
- Students will explain the connection between greenhouse gas emissions from modern processes (industrial, transportation, agricultural, etc.) and our current climate crisis.
- Students will interpret global data sets which show specific examples of global climate change, will make connections between different data sets and offer hypotheses about why these connections may exist.
Human Impacts of Climate Change: Climate change impacts human societies by altering weather patterns, increasing natural disasters, and affecting resources, requiring adaptation and mitigation strategies for sustainable living.
- Students will describe examples of how the global climate crisis is affecting human societies now and in the future.
- Students will present specific examples of how humans may mitigate the future effects of climate change.

Advice for Educators: Doing observation and discussion with students is an incredibly powerful way to get students to share in a collaborative way. I am always surprised at how students display flexible thinking during the process - there’s always a student or two who is adamant about what they think they are seeing, but then after listening to others they quickly change their thinking. Some groups where students feel more inhibited can show a reluctance to participate in the discussions at first. Giving students a chance to write first makes a big difference.
One of the important parts of this unit is the fenceposts activity, in which students get a chance to practice the process of thinking through what design tools might work best for a particular survey question. Although it can be somewhat time consuming to have students vote on which design tool to use, I think it was quite powerful to go through that exercise, because students really had to defend their choice of a particular tool. Then, after the activity, they can evaluate their choices. But giving students choice and voice in this process was important - not only did they buy into the activity, but it forced them to think more deeply about the design choices.
When doing the Data Sketches activity, don’t worry about students’ lack of background knowledge in terms of the connections they come up with. The purpose of this activity is not to get them to develop sophisticated claims, but rather to look at data and ask questions about what possible correlations might be possible. The questions they raise are more important than the answers they come up with.

Assessment: Each lesson has both formative and summative assessment pieces. For the BIO lesson portion of the unit, I only provided formative feedback. The goal was to encourage students to participate in a low risk environment and work in a collaborative and cooperative environment as they develop data analysis skills used to meet our learning objectives.
Advice for Educators: It was really surprising how the Observation & Discussion facilitation techniques helped classroom cultures. Specifically, improving collaboration and cooperation. The norms established in this activity became the norms for many of our classroom activities. It helps slow students down, listen to what others have to say, and reflect on the problem at hand. The parking lot questions generated were surprisingly insightful and provided a link to the remainder of the unit. I found it impactful to connect the global data sets for the BIO lesson to the final unit project, a summative assessment on the effects of human activity on freshwater resources in the Colorado River Basin.
One must be willing to allocate the time needed to add this to your unit. The emphasis on using the BIO lesson was to help students when analyzing data, and I found that these skill sets helped do that:
- Create a classroom culture built on collaboration and cooperation
- Slow down the process
- Value listening to other people's observations
- Reflect on what you see and hear
- Clearly identify what you know and what you do not about the data set
This was more important than focusing on how to graph, mathematically, quantify data, etc.. What is the data telling us and what is missing?

Fenceposts Survey Questions
Assessment (Optional): [none listed]
Advice for Educators: The Fencepost activity was extraordinarily insightful as an informal assessment of background knowledge of students at the beginning of the unit. The instant visualization that only two students out of all classes had ever grown anything from seed to flower or fruit led to the incorporation of an additional activity. Students were given the opportunity to sprout seeds, grow them hydroponically, and then take them home or plant them in a campus garden.

Tides: Understanding Impacts on Human Activity Around the Globe
Topic Keyword(s):
Earth & the Solar System
Weather & Climate
Guiding Question(s):
- How might tides impact human activity in different parts of the globe?
- Are there connections between tidal patterns and sea surface temperatures?
- What impact, if any, might high and low tides have on sea surface temperatures?
Placement in Curriculum: I started with an overall introduction to Earth and the Solar System, starting with the Big Bang and the theories that support it. Which led into the theories behind the creation of our moon, and giving them some background information on the moon and how it is both impacted by, and impacts gravity on Earth. With this basis for the phenomenon of how the moon impacts our tides I started with BIO.
Learning Objectives:
- Students will explore how high and low tides vary in different parts of the world.
- Students will compare and contrast visual datasets depicting tidal variations, sea surface temperatures, and shipping routes.
- Students will look for patterns and determine if there is a correlation between the datasets, and what that correlation may imply.
Standards Alignment:
Disciplinary Core Ideas:
- ESS1.A: Patterns of the apparent motion of the sun, the moon, and stars in the sky can be observed, described, predicted, and explained with models.
- ESS2.C: Global movements of water and its changes in form are propelled by sunlight and gravity.
- ESS2.D: The ocean exerts a major influence on weather and climate by absorbing energy from the sun, releasing it over time, and globally redistributing it through ocean currents.
Crosscutting Concepts:
- Patterns
- Graphs, charts, and images can be used to identify patterns in data.
- Patterns in rates of change and other numerical relationships can provide information about natural systems.
- Patterns can be used to identify cause-and-effect relationships.
- Models
Models can be used to represent systems and their interactions—such as inputs, processes and outputs—and energy and matter flows within systems.
Models are limited in that they only represent certain aspects of the system under study.
Science and Engineering Practices
- Developing and Using Models
- Evaluate limitations of a model for a proposed object or tool.
- Develop and/or use a model to predict and/or describe phenomena.
- Analyzing and Interpreting Data
- Use graphical displays (e.g., maps, charts, graphs, and/or tables) of large data sets to identify temporal and spatial relationships.
- Distinguish between causal and correlational relationships in data.
- Analyze and interpret data to provide evidence for phenomena.
- Consider limitations of data analysis (e.g., measurement error), and/or seek to improve precision and accuracy of data with better technological tools and methods (e.g., multiple trials).
- Analyze and interpret data to determine similarities and differences in findings.

Assessment (Optional): I assigned the Data Visualization Choices worksheet as homework. In hindsight, if I had more time, I would have reviewed the worksheet with my students as a class. I did not use any formal assessment tools. However, if I were to do it again, I might have the students do a personal assessment of their own participation.
Advice for Educators: Don’t be intimidated by the Observation & Discussion facilitation approach or their familiarity with visual datasets. Application of this unit takes practice, but getting it “wrong” can be informative, and your students will most likely enjoy it all the same. For teachers of younger students (6th grade) to give some more scaffolding, maybe even present an example of both fenceposts and data sketches before launching the activities. If I were to do it again, I might use the parking lot later, when the relevant data sketches are being introduced. I think that would lead to more relevant questions to further the lesson and the greater unit they are a part of.

Assessment (Optional): Have the students write a claim, evidence, and reasoning in response to the guiding question: Why should communities prepare for drought?
Advice for Educators:
The most surprising and successful moments came from the hands-on activities. Students were particularly engaged during the Observation & Discussion exercise, where they closely examined drought images and shared their observations. This activity not only enhanced their observational skills but also fostered a collaborative learning environment. The Fence Post Activity was another highlight, as it allowed students to visually and collectively analyze data, making patterns and trends more comprehensible.
Students needed more support in connecting practical activities to theoretical concepts. They often found it challenging to link their observations and data analysis to the broader causes and effects of droughts. To address this, I incorporated more guided discussions and scaffolded reflection activities, which helped bridge this gap.
For educators planning to use this unit, I recommend emphasizing the connection between activities and theoretical knowledge. Regularly check for understanding and be flexible in providing differentiated support. Encourage students to share their ideas and observations openly, fostering a collaborative and inclusive classroom atmosphere. Finally, ensure that reflective writing and discussions are integral parts of the unit, as these help solidify students' understanding and link practical experiences to theoretical concepts.
Background Information (Optional):
Droughts are complex phenomena influenced by a variety of interrelated factors. Here are the primary contributors:
- Climate and Weather Patterns:
- Temperature: Higher temperatures increase evaporation rates and reduce water availability.
- Precipitation Deficit: Prolonged periods of below-average precipitation are the direct cause of meteorological droughts.
- Wind Patterns: Changes in wind patterns can shift weather systems, leading to reduced rainfall in certain areas.
- Geographical Factors:
- Topography: Mountain ranges can block moist air masses, creating rain shadows and arid regions.
- Proximity to Water Bodies: Areas far from large water bodies tend to receive less rainfall.
- Soil Characteristics:
- Soil Moisture Retention: Soils with low moisture retention capacities (e.g., sandy soils) can exacerbate drought conditions.
- Soil Type and Vegetation: Different soil types and vegetation cover influence the rate of evaporation and water retention.
- Human Activities:
- Agricultural Practices: Over-irrigation, deforestation, and poor land management can deplete water resources.
- Urbanization: Increased surface runoff and reduced natural recharge areas can lower groundwater levels.
- Water Usage: Excessive withdrawal of water for industrial, agricultural, and domestic use can contribute to drought.
- Climate Change:
- Global Warming: Rising global temperatures alter precipitation patterns and increase the frequency and severity of droughts.
Shifts in Climate Zones: Changing climate zones can make some areas more prone to droughts.

Assessment (Optional): Have the students write a claim, evidence, and reasoning in response to the guiding question: Why are bats essential to the environment?
Advice for Educators: Teaching this unit why bats are essential to the environment has been highly rewarding, with several noteworthy successes and challenges, and the most successful moments included the initial Observation & Discussion activity, where students demonstrated keen observational skills and engaged in thoughtful discussions about bat images. This exercise helped them build a solid foundation for understanding the importance of bats. Students were particularly captivated by the interactive and visual aspects of the unit, such as the fencepost activity and creating bat posters, which fostered creativity and collaboration.
I found that students needed more support during the research phase, specifically in navigating and synthesizing information from the provided websites. Some students struggled with identifying reliable sources and summarizing their findings effectively. Providing additional guidance on research skills and perhaps a structured template for the posters could alleviate these difficulties.
If I were to teach this unit again, I would integrate more structured scaffolding for the research activities and allocate more time to the map design and data interpretation sections. Incorporating a peer review process for the posters could also enhance the learning experience, allowing students to receive constructive feedback before the final presentation.
For educators interested in using this unit, I advise emphasizing the interactive and visual components, as they significantly enhance student engagement. Additionally, ensure that students have ample opportunities to discuss and reflect on their learning, as these moments are crucial for deepening their understanding of the material. Finally, be prepared to offer extra support during the research phase to help students navigate and synthesize information effectively.
Background Information:
Bats are essential to the environment for several reasons:
- Pollination: Many bat species are pollinators, especially in tropical and desert climates. They pollinate various plants, including fruits like bananas, mangoes, guavas, and agave plants.
- Seed Dispersal: Bats help with seed dispersal, which is crucial for the regeneration and spread of various plant species. This helps maintain healthy forest ecosystems and promotes biodiversity.
- Pest Control: Bats consume vast amounts of insects, including agricultural pests and mosquitoes. This natural pest control reduces the need for chemical pesticides, benefiting crops and human health.
- Nutrient Cycling: Bat guano (feces) is a rich source of nutrients that enriches soil, promoting plant growth and aiding in ecosystem nutrient cycling.
- Indicator Species: Bats are sensitive to environmental changes and can serve as indicators of ecosystem health. A decline in bat populations often signals broader ecological issues.

Assessment: Data Map Write-up
Advice for Educators: The unit allows for the teacher to tailor interesting images that support the unit objectives and to facilitate meaningful interactions between students and with the images. Students found the student product (the Redesigned Datamap) to be enjoyable and out of the ordinary, feeling more like an art project than a science assignment. At the same time, students readily discussed what they saw on their maps with their peers, engaging in productive and developmentally appropriate explanation and argument. Some students needed support adding the correct designs to their maps, especially if a small area showed a range of data that wasn’t necessarily shown in a clear or patterned manner on the original map. Students also had difficulty combining three tracing paper maps and being able to see the comparison of data from all three maps together. Students had further difficulty, possibly due to the previous factor, making observations and making meaning of the comparison of data shown on the three maps for a given location on the map. If I were to teach this unit again I would limit the geographical scope of the overall map, choosing to show one city or country instead of the entire world. Teachers should thoroughly review datamap originals and consider technical language used, incorporating as background content into the unit. Additionally, teachers should plan for how students will use the finished student products in their curriculum, and consider how the combination of the three redesigned maps may be a jumping off point for further exploration of a topic or phenomenon in their curriculum.

Assessment (Optional): Assessment during this unit was participation based, where students received full credit for completing all activities. Following the BIO unit, students engaged in traditional learning activities and completed formative and summative electronic Canvas assessments.
Advice for Educators: Students were creative with the chosen artwork and generated stories involving the human figures. When overlaying the data sketches maps, most students had an “aha” moment of noticing that earthquakes, volcanoes, and plate boundaries almost all line up perfectly. However, students needed more time for data sketches that I anticipated. Seeing that students were all engaged in the activity made this extension a worthwhile use of extra time.
