Unit 5 — Shape and Function: Bird Beaks and Bird Feeders
Description
Students research local birds and the shapes of their beaks, graphing the variety of species in their area. Students learn how beak shape determines what food a bird can eat. Using this knowledge, students design and build bird feeders that attract specific bird species. The unit integrates observation skills, data collection, and design thinking while connecting to local science and ecology.
Essential Questions
- How does the shape of a bird's beak relate to what it eats?
- How can we design a bird feeder for specific bird species?
- What role does form play in function?
Learning Objectives
- Research and observe local bird species and their characteristics
- Collect and graph data on bird species and beak types
- Understand the relationship between form and function
- Design a bird feeder for a chosen species
- Test and refine the feeder design
Supplemental Resources
- Graph paper for plotting bird species data
- Markers and colored pencils for labeling bird beak types
- Index cards for recording bird observations in the field
- Sticky notes for marking design features on feeder prototype

Digital Literacy
Measurement
Standards for Mathematical Practice
Students write and share observations in science notebooks, create digital stories about plant growth using pictures and words, and communicate engineering design ideas through drawings and descriptions.
Students count objects, create and interpret bar graphs to represent data, measure plant heights with rulers, compare quantities, and use data to analyze engineering design test results.
Formative Assessments
- Field observation notes of local birds
- Graph of bird species and beak shapes observed
- Bird feeder design sketch with labeled features
- Testing record showing which birds visit the feeder
Summative Assessment
Functional bird feeder design that successfully attracts target bird species

Alternative Assessment
Students may demonstrate understanding through a picture-based sorting activity where they match bird images to beak types and food sources, or through a teacher-led discussion about how beak shape affects eating. Visual supports such as labeled diagrams and real or model bird beaks may be provided to support learning.
IEP (Individualized Education Program)
During observation and data collection activities, provide students with picture-based recording tools so they can document bird species and beak shapes through drawing or pointing rather than writing. When sharing design ideas for bird feeders, allow students to explain their thinking aloud or act it out rather than relying on written labels. Break multi-step tasks like building and testing the feeder into shorter, clearly sequenced steps with a visual checklist, and check in frequently to provide feedback and keep students on track. Scaffolded graphic organizers with images of beak shapes and food types can support students in making the form-and-function connection.
Section 504
Ensure students have preferential seating during whole-group observations and discussions so they can clearly see visual materials such as bird photographs and beak-type diagrams. Provide extended time during data recording and feeder design tasks, and offer a low-distraction workspace during building and testing phases. Oral responses should be accepted in place of written work whenever the task is not specifically assessing drawing or recording skills.
ELL / MLL
Support vocabulary development around key content terms — such as beak, feeder, seed, and species — using photographs, real objects, and labeled picture cards that students can reference throughout the unit. Provide simplified, visual directions for each phase of the design and building process, and use gestures and demonstrations when introducing new concepts. When possible, connect the bird species studied to birds students may recognize from their home environment or cultural background to build meaningful context.
At Risk (RTI)
Begin by activating what students already know about birds they have seen in their neighborhood or yard, and use that familiarity as an entry point into beak shape and feeding behavior. Offer picture-supported recording tools and reduce the complexity of graphing tasks so students are focused on noticing patterns rather than managing an unfamiliar format. During the feeder design and building phase, provide simple, concrete examples of how shape affects function using everyday materials students can explore hands-on before making design decisions.
Gifted & Talented
Invite students to investigate how beak shape has changed over time in relation to a bird's environment, connecting the concept of form and function to the broader idea of adaptation. Students may explore the feeding habits of multiple bird species and consider how to design a feeder that either attracts one very specific species or deliberately serves several different types of beaks, justifying their design choices with evidence from their research. Encourage students to reflect on how engineers use observations from nature when solving design problems, deepening their understanding of the relationship between science and design thinking.
