Challenge 2C: Design by Nature
(4th and 5th Grade)

YOUR CHALLENGE:

Engineers design and build new tools and materials to make our lives better. When engineers get stuck, they often look to nature to solve problems. Copying how living things are built or function to invent something brand new is called biomimicry. Velcro was designed after an inventor saw tiny hooks on seed burrs sticking to his dog’s fur. Architects have taken inspiration from termite mounds to build shopping malls that use wind to naturally stay cool. Scientists even looked at lotus leaves, which stay clean because water and dirt slide right off, to invent paint that helps buildings clean themselves! Can plants also be the inspiration for nature-based solutions that make your community cooler, safer, and better for everyone? 

Step into the shoes of an eco-architect and incorporate at least one plant adaptation in a building so it can tackle an environmental threat we have in South Florida. The plant adaptation you choose should help reinforce your building against threats like extreme heat, flooding, sea-level rise, pollution, heavy rain, little vegetation, or any other issue you see in your community. You can reimagine a building that already exists or you can design one that is brand new.

Create a 3D model no larger than 12”x12”x12” of your eco-inspired building using recycled materials. Make sure your building is able to stand upright. In 50-75 words, describe the plant adaptation that inspired your design and share how incorporating plant adaptations strengthened your building.  Lastly, come up with a name for your new building design that reflects its unique properties.

✓  Submission Requirements:
 Original student-made 3D plant-inspired building model that can stand upright on its own and is no larger than 12”x12″x12″.
 Include the student’s first name and last initial, student grade level, teacher’s name and school name attached via tag or sticker directly on the plant model.
 Written description on separate sheet of paper must include the plant’s name and description of specific plant-inspired trait that supports the building in a maximum of 50-100 words.
 The written description must include the student’s first name and last initial, student grade level, teacher’s name, and school name ON THE BACK OF THE PAPER.
 Digital Entry Form (for school and student information only). Electronic uploads of 3D model and written descriptions will not be reviewed.
