Flashcard 1: Which animal part helps a duck stay dry because water rolls off it?
Answer: Feathers. Their special oil coating makes them waterproof.
Flashcard 2: Which design feature best mimics fish fins for swimming: flat plastic pieces on the sides or soft cotton?
Answer: Flat plastic pieces on the sides. Flat surfaces push water for propulsion.
Flashcard 3: Which material best mimics fur for warmth: aluminum foil, cotton, or sandpaper?
Answer: Cotton. Fluffy fibers trap air for insulation like fur.
Flashcard 4: Identify the first step when designing a biomimicry solution.
Answer: Name the problem you want to solve. Clear problem definition guides the design process.
Flashcard 5: Which material best mimics a turtle shell for protection: tissue paper, cardboard, or yarn?
Answer: Cardboard. Rigid and strong like a real shell.
Flashcard 6: Which plant part anchors the plant and takes in water from the soil?
Answer: Roots. Also store nutrients and stabilize soil.
Flashcard 7: Which animal part helps a bird pick up and hold food?
Answer: Beak. Shape varies by diet (curved for seeds, pointed for insects).
Flashcard 8: What is biomimicry in science?
Answer: Designing solutions by copying how plants or animals work. Nature's designs inspire human solutions to problems.
Flashcard 9: Which material best mimics bird feathers to keep water off: wax paper, sponge, or cotton ball?
Answer: Wax paper. Waxy surface repels water like feathers do.
Flashcard 10: Which change best improves a shell-like design that bends too easily: thicker cardboard or thinner paper?
Answer: Thicker cardboard. More material adds strength and rigidity.
Flashcard 11: Identify the best test to check a water-repellent design that mimics feathers.
Answer: Sprinkle or drop water and see if it rolls off. Tests if water beads up and rolls away.
Flashcard 12: What should you do after choosing a plant or animal part to copy?
Answer: Identify the job (function) the part does. Understanding function helps choose right materials.
Flashcard 13: Which option best describes the function of fur on many mammals?
Answer: Keeps the animal warm by trapping air. Air pockets between hairs provide insulation.
Flashcard 14: Which material best mimics a beak for picking up objects: spoon, string, or paper towel?
Answer: Spoon. Hard, curved shape grabs like a bird's beak.
Flashcard 15: Which design choice best mimics a chameleon for hiding: matching colors or making loud sounds?
Answer: Matching colors. Chameleons blend in by changing color.
Flashcard 16: Which material is best to mimic a porcupine quill for poking defense: toothpick or sponge?
Answer: Toothpick. Toothpicks are sharp and pointed like quills.
Flashcard 17: Which structure should you add to mimic a beaver tail for pushing water: wide flat piece or thin string?
Answer: Wide flat piece. Beaver tails are broad and flat to push water.
Flashcard 18: Which material is the best match to mimic webbed feet: flat plastic sheet, sand, or yarn ball?
Answer: Flat plastic sheet. Flat plastic spreads out like webbing between toes.
Flashcard 19: What is biomimicry in simple science words?
Answer: Designing something by copying how plants or animals work. Biomimicry means learning from nature to solve problems.
Flashcard 20: Identify the function that bird feathers help with most: breathing, flying, or drinking water.
Answer: Flying. Feathers are lightweight and shaped for flight.
Flashcard 21: Identify the function that a turtle shell helps with most: protection, eating, or hearing.
Answer: Protection. Shells are hard coverings that shield from danger.
Flashcard 22: Identify the function that a duck’s webbed feet help with most: swimming, climbing, or digging.
Answer: Swimming. Webbed feet push water like paddles.
Flashcard 23: Which material best mimics a plant stem that must bend without breaking: flexible straw or brittle cracker?
Answer: Flexible straw. Straws bend without snapping like healthy stems.
Flashcard 24: What is a fair test for a design: change only one thing and keep the rest the same?
Answer: Yes, change only one variable at a time. Fair tests isolate one variable to see its effect.
Flashcard 25: Which option is the best way to improve a biomimicry design after testing: ignore results or redesign?
Answer: Redesign using what you learned from the test. Testing shows what works so you can improve.
Flashcard 26: Identify the best record to keep during building and testing: guesses only or notes and drawings.
Answer: Notes and drawings. Records help you remember what worked and didn't.
Flashcard 27: Which question checks whether your solution truly mimics the part: “Does it do the same job?”
Answer: Yes, it should do the same job (function). True biomimicry copies nature's function, not just looks.
Flashcard 28: Which material is the best match to mimic bird feathers for lightness: paper, rocks, or metal spoon?
Answer: Paper. Paper is lightweight like feathers.
Flashcard 29: Which material is the best match to mimic a turtle shell for protection: cardboard, cotton, or tissue?
Answer: Cardboard. Cardboard is stiff and protective like a shell.
Flashcard 30: What is biomimicry in 1st grade science?
Answer: Using nature ideas to solve a problem. Copying how plants and animals work helps us create solutions.
