Earthrise

Purpose

Students are introduced to the Earthrise phenomenon by seeing the Earth as the Apollo 8 astronauts viewed our home planet for the first time from the Moon.  They will analyze a time series of mapped plots of Earth science variables that NASA monitors to better understand the Earth System. Students will document changes of a variable over time as they create a new visualization. They will share this visualization with a peer who has monitored a different Earth System variable and work collaboratively to make observations about temporal and spatial change making inferences about how these variables may be related. As a result, they develop research questions which students may use in future investigations.

This lesson can be used as a launching activity for introducing Earth Systems or the phenomenon of Earthrise.

  • Develop research questions

NASA Phenomenon Connection

On Christmas Eve, 1968, none of the astronauts aboard Apollo 8 were prepared for the spellbinding moment when they would first see their home planet rise from behind the desolate lunar horizon. The vision of Earth provided them the first spot of color as they floated in the blackness of space, orbiting the lunar surface.  "Earthrise" is the name given to a photograph of the Earth taken by William Anders during lunar orbit.

Essential Questions

  1. How is the global system changing?
  2. What other parts of the Earth System change over time?  
  3. Where do these changes tend to occur?
  4. What variables appear to be correlated?

Background Information

The "Earthrise" photograph became one of the most famous photos from all of the Apollo missions and one of the most reproduced space photographs of all time. It has been credited for inspiring the beginning of the environmental movement as this view underscored the need to better understand and protect the Earth. In Life Magazine's 100 Photographs that Changed the World edition, wilderness photographer Galen Rowell called Earthrise, "the most influential environmental photograph ever taken."

NASA is, and will continue to be, in the forefront of researching our planet’s interconnected systems, from a global scale down to minute processes in the Earth System. NASA is focused on developing a scientific understanding of the Earth as a whole system and its response to natural or human-induced changes. NASA's research on the Earth focuses on the following five questions.  Answering these questions is vital to understanding the Earth and protecting it for future generations.

  • How is the global system changing?
  • What are the primary forces of the Earth system?
  • How does the Earth system respond to natural and human-induced changes?
  • What are the consequences of change in the Earth system for human civilization?
  • How well can we predict future changes in the Earth system?

The Earth is a system of interacting parts that work together to form our complex planet; it is made up of five major parts or subsystems: Atmosphere, Hydrosphere, Biosphere, Cryosphere, and Geosphere which are connected to each other in a complex web of processes.

Sphere Interaction

As students review the Earth System poster-cards in their collaborative teams, help them to connect the different sphere interactions by highlighting the following interactions with the driving questions below to engage prior knowledge and activate learning.

  • This 5-E lesson connects the shape of Earth's surface (and the names of the features that correspond to those shapes and textures) to the processes that form them. It also introduces students to how scientists use Earth to gain a better understanding of other planetary bodies in the solar system.

Procedure

Introduce Earthrise

earthriseBW
Photograph 1. Earthrise in black and white

Display the iconic Earthrise Photograph #1 (black and white) to the class. Present the following questions to students to answer:

  1. What are the main features of the picture?

The Earth is rising over the lunar surface. The illuminated side of the Earth is rising above the horizon, showing the land, oceans, and swirling clouds that are part of the Earth system.

  1. Describe the different environments displayed in the photograph.
    • How are they similar?  
      • Solid rocky surfaces both exist on the Earth and the Moon.
    • How are they different?
      • The Moon’s gray cratered surface contrasts sharply with the black of space. On the other hand, the Earth has many different shades and patterns.
  2. Have students work with a partner to analyze the image and share their observations.

  3. Next, students work with their partner to make inferences about the photograph by presenting the following questions to answer:

    1. Where is this picture taken from? How do you know? The Moon.  This is a natural planetary object and is close to Earth like the Moon.
    2. What is happening in the picture? The Earth sits beyond the Moon’s horizon.  The Moon orbits the Earth.
    3. What is most notable about these environments? The Earth rests in the emptiness and darkness of space; its surface is differentiated with white and dark features.  The Moon’s surface has a bumpy texture with light and dark materials. 
  4. Now, present Earthrise photograph #2 (in color) and have them observe the photo for new observations and inferences.

    earthrisecolor
    Photograph 2. Earthrise in color
  5. Describe the different environments displayed in the photograph.

    1. How are they similar? There are similar shades of brown on the lunar and Earth surface
    2. How are they different? Earth’s color palette is more striking with more colors.  The texture of the surfaces is hard to compare since the Moon is closer to the camera.
    3. What is most notable about these environments when viewing in color? Earth’s coloration includes shades of white, blue, brown, reds, and greens, whereas the Moon’s surface is monotones of white, grey, and browns.
  6. Explain to students that Photograph #1 is picture was captured on December 24, 1968, from astronauts aboard Apollo 8, the first ever manned satellite of another world.  Although it is not the first image of Earth taken from space, it is the first image of the Earth taken from the perspective of Earth rising above the horizon of another world. Apollo 8 astronauts Frank Borman, James Lovell, and William Anders were coming around from the far side of the Moon on their fourth orbit. William Anders photographed the Moon from the right side window of the spacecraft and exclaimed: “Oh my God, look at that picture over there! There’s the Earth comin’ up. Wow, is that pretty!”

    The second image is the first photograph of Earth in color taken as Earth rose above the lunar horizon. This photograph became one of the most famous photos from all of the Apollo missions and one of the most reproduced space photographs of all time. It has been credited for inspiring the beginning of the environmental movement as this view underscored the need to better understand and protect the Earth. In Life Magazine's 100 Photographs that Changed the World edition, wilderness photographer Galen Rowell called Earthrise, "the most influential environmental photograph ever taken."

  7. Ask students to brainstorm and share what new information the color photograph provides about our home planet.  What may these colors represent? What sphere in the Earth System do they belong? Direct students to connect their descriptions of the natural phenomena to the observed color, as well as to the name of the sphere in the Earth System which they belong

  • Blues: Answers may include but not limited to...Oceans and other water bodies as part of the Hydrosphere
  • Whites:  Answers may include but not limited to...Clouds, snow, and ice as part of the Cryosphere; white coloration may also indicate urban environments belonging to the Geosphere.
  • Reds: Answers may include but not limited to...Deserts and other landforms as part of the Geosphere; the ocean may also be observed by the appearance of certain algal blooms belonging to the Biosphere.
  • Browns: Answers may include but not limited to...Deserts and other landforms in the Geosphere; brown coloration of waterways may also be observed by the appearance of silt-laden water in the Hydrosphere; brown may also be observed on land due to changes of leaf color in temperate forests in the autumn season as part of the Biosphere.
  • Greens: Answers may include but not limited to...Forests and vegetated landforms, as part of the Biosphere.

  1. Present the following question, “What did you see outside in nature on your way to school today?” 
  2. Students work in their teams to brainstorm the various parts of the system that you’ve encountered today.
    1. Students will write each idea on a sticky note.
  3. Have students come to the front of the board and place their sticky note.
  4. As a class, review and sort their ideas about different parts of nature that they have encountered into the four major spheres of the Earth System. NOTE: During this activity, we will focus on the Atmosphere, Biosphere, Geosphere, and Hydrosphere. For the purpose of this activity, we will consider the Cryosphere as part of the Hydrosphere. 
    1. Organize the notes under the following headers, after the students have identified the spheres through class discussion.

Part 1:  Explore Time Series Poster-Cards

  1. Distribute poster-cards of the four variables among students.  

    variables

         Review the variables being researched:

Variable Background
  1. Each student should receive the poster-cards of the following months and associate colored pencils to review and analyze:

    1. January - red
    2. March - yellow
    3. May - green
    4. July - blue
    5. September - purple
    6. November - brownEarthrise Map Inventory, Part 1 & 2 Student Sheet
  2. Distribute the Earthrise Map Inventory, Part 1 & 2 Student Sheet to each student, as well as coloring pencils (six different colors per student - or groups to share).
  3. Students should review the Earth System poster-cards of their variable.  
  4. Students should create a key identifying the color to the time in the space to the right.
  5. Using the blank map provided (and coloring pencils), students document areas of activity and/or change of their variable. Note:  They should use a different color pencil for each of the six different time periods. For example, students would compare January to March poster-cards. They could use a red pencil to shade the map where students observe a medium to high concentration of the variable. Next, they analyze the poster-cards for March and document (on the same sheet) the locations of the high concentrations using a yellow pencil.  Repeat this process for each of the months. After repeated updates to the same map, geographic “hot spots” will become obvious, as well as months that experienced a shift in geographic range.

Part 2: Summarize Your FindingsStudent Sheet, Part 2

  1. Students summarize their findings on the Student Sheet, Part 2.
    1. Here, they document the variable being analyzed by identifying five qualitative and five quantitative observations.  (Qualitative observations use your senses to observe the results; Quantitative observations are measurable and described using numbers and data; they can be collected with instruments such as rulers, balances, thermometers, etc.)
    2. Students also craft five researchable questions that come to mind in their analysis.

Part 3: Communicate Your Finding and Expand Your Research

  1. Distribute Part 3 of the Earthrise Map Inventory.
  2. Students team up with a student exploring a different variable.  
  3. Together, they complete the two tables by analyzing the two science variables as they compare their observations. They document patterns or relationships found among the two in Table A.
  4. Explain to students the types of questions:
    1. Descriptive Questions:  describe the variables you arePart 3 of the Earthrise Map Inventory measuring.
    2. Comparative Questions: examine the differences between two or more groups on one or more dependent variables
    3. Correlative Questions: analyze the causal relationships, associations, trends and/or interactions amongst two or more variables on one or more groups
  5. In Table B., students work together to create their own questions using the three different types of questions: Descriptive, Comparative, and Correlative.

Part 4: Share your Research with a Gallery Walk

  1. Students share their findings through a gallery walk.  Have nearly half of your students post their data sheets on the walls and disperse themselves around the room.  An important factor is that the student works are spread far enough apart to reduce significant crowding.
  2. The other half will walk around and visit the displayed work while carrying a clipboard with their own data.  They will share their own data through the process.
  3. Post the following questions on the board or projector for the students to answer as they conduct their Gallery Walk. Students will be expected to present their answers at the end in an exit ticket.  Exit
    1. How does each of the different variables change over the year? (evaluate)
    2. Which variable seems to affect another variable?  (apply)
    3. What processes connect them? How do you know?  (understand)
