PRINTMAKING ECOSYSTEMS: CARRYING CAPACITY AND BIODIVERSITY 9-12
PRINTMAKING ECOSYSTEMS: CARRYING CAPACITY AND BIODIVERSITY
Learning Description
In this lesson, students will explore how biotic and abiotic factors influence ecosystems, species distribution, and carrying capacity. Through printmaking, students will create a visual representation of species interactions in a chosen biome, considering competition, predation, and resource availability. Each print will contribute to a collaborative class ecosystem model, showing how species coexist and how environmental changes impact populations.

Key Vocabulary
Content Vocabulary
- Carrying capacity – The maximum number of organisms an ecosystem can support
- Biotic factors – Living components of an ecosystem (plants, animals, fungi)
- Abiotic factors – Nonliving components of an ecosystem (water, temperature, soil)
- Biodiversity – The variety of life in an ecosystem
- Predation – A biological interaction where one organism feeds on another
- Competition – Organisms competing for limited resources
Arts Vocabulary
- Printmaking – The art or technique of making prints, especially as practiced in engraving, etching, dry point, woodcut or serigraphy
- Relief print – A printmaking technique in which a design is carved into a material and inked for printing
- Brayer – A small roller for inking type by hand, usually for making a proof
- Composition – How an artist arranges the Elements of Art (line, shape, form, value, color, space, texture) to create an artwork
- Contrast – The arrangement of opposite elements in a composition (light vs. dark, rough vs. smooth, etc.) Similar to variety, which refers to the differences in a work, achieved by using different shapes, textures, colors and values
Materials
- Sketchbooks or STEAM journals/pencils
- Styrofoam sheets
- Dull pencils or ball point pens
- Brayers
- Water based printing ink
- Printing paper (white, colored, textured; mixed media paper works well)
- Colored pencils or art sticks
- Drying racks or designated drying space
- Paper towels to wipe ink off of styrofoam plates
- Colored index cards
- Trays for ink
- Optional: Colored pencils. art sticks, watercolors and paint brushes, etc.
Instructional Design
Opening/Activating Strategy
Activator: The "Survival Game"
- Objective: Help students understand carrying capacity and competition for resources.
- Activity instructions:
- Set the scene:
- Tell students they are deer living in a forest. The classroom represents their habitat.
- They must "find food" (colored index cards scattered around the room).
- Rules:
- When the teacher says "Go", students must pick up only one card at a time and bring it back to their seat.
- After each round, some students will be "eliminated" (didn’t find food).
- Increase competition by adding/removing "food" cards in each round.
- Introduce a "predator" (teacher or student) who can "tag" students (eliminating them from the population).
- Reflection: Discuss what happens to the population when resources become scarce or competition increases.
- Set the scene:
- Connect to lesson: This game simulates carrying capacity—when resources run out, populations decline.
- Ask students, “How does this apply to real ecosystems?”. Transition into a class discussion about biotic and abiotic factors that influence populations.
Discussion Questions:
- What factors determine how many organisms an ecosystem can support?
- How do species interact in ecosystems (predation, competition, symbiosis)?
- What happens when a species population grows too large?
Work Session
Research & Brainstorm:
- As a class, students will choose one of Earth’s major biomes or aquatic ecosystems:
- Tropical Rainforest
- Desert
- Grassland
- Taiga
- Tundra
- Freshwater
- Estuary
- Marine
- Students will research the biotic and abiotic factors in their chosen biome.
- Students will then sketch a food web/chain with at least:
- One producer (plant)
- Two primary consumers (herbivores)
- One predator
- One decomposer
- Before students begin their printmaking, they will complete a short written response:
- What biome did you choose?
- Which biotic and abiotic factors did you include?
- How will your print show interactions in the ecosystem?
Give students the following instructions to create their prints:
- Create a Printing Plate:
- Choose one species from your ecosystem and sketch it on paper.
- Use a dull pencil or ballpoint pen to carve design into the foam—press firmly but avoid puncturing all the way through.
- Encourage students to sketch lightly first before carving to avoid mistakes.
- Add textural details to represent how the species interacts with the ecosystem.
- Carving Techniques:
- Keep lines simple and bold for clear prints; intricate details may not transfer well.
- Reverse letters or numbers if including text, as prints will be a mirror image.
- Vary line thickness for added depth—thicker lines hold more ink, while thinner lines create subtle details.
- Inking the Plate:
- Roll out a thin, even layer of ink on a tray before applying to the styrofoam plate with a brayer.
- Roll the inked brayer over the styrofoam plate. Make sure ink covers the entire design, but avoid excessive ink, which can cause smudging.
- Test prints on scrap paper before making the final print.
- Printing Process:
- Place the inked plate face down on the final paper and press evenly with hands or a clean brayer.
- Avoid shifting or sliding the plate while printing to prevent smudging.
- Lift the plate carefully to reveal the design.
- Encourage students to appreciate the imperfections as part of the artistic process!
- Creative Enhancements:
- Try different colors – Experiment with layering multiple prints in different colors.
- Overlap prints – Print the same design multiple times on one page to create patterns.
- Use mixed media – Combine printmaking with drawing, collage, or watercolor backgrounds for unique effects.
Collaborative Ecosystem Model:
- Assemble a class biome display:
- Each student’s print represents one species in the biome.
- Arrange prints based on interactions (e.g., predator near prey, plants near decomposers, etc.).
- Use labels or speech bubbles to explain each species’ role in the ecosystem.
Closing Reflection
- Facilitate a discussion around the following questions:
- How does your species interact with others in the ecosystem?
- What factors affect the ecosystem’s population size (predation, competition, disease, etc.)?
- How does your print visually represent the species’ role?
- What happens when the carrying capacity is exceeded in this biome?
- Students will complete a short reflection (written or through video) explaining:
- What biotic and abiotic factors are represented in your collaborative ecosystem model?
- How does your print demonstrate carrying capacity, competition, or species interactions?
- What challenges did you face in printmaking, and how did you overcome them?
Assessments
Formative
Think-Pair-Share (during brainstorming)
- After students sketch their food web or ecosystem interactions, students will pair up and explain their choices.
- Teacher circulates to assess understanding of content and the printmaking process.
Mini-Checkpoint Questions (before printing)
- Before students carve their print, they must complete a short written response:
- What biome did you choose?
- Which biotic and abiotic factors did you include?
- How will your print show interactions in the ecosystem?
Summative
Final Print and Reflection (Written or Video)
- Students will create a short reflection explaining:
- What biotic and abiotic factors are represented in your collaborative ecosystem model?
- How does your print demonstrate carrying capacity, competition, or species interactions?
- What challenges did you face in printmaking, and how did you overcome them?
