Example Questions
Example Question #2 : Plant And Animal Survival
The foundation of a house keeps it stable and in place. What part of the plant does the same?
Leaves
Roots
Flower
Roots
The roots of a plant keep it stable and in place. Humans have mimicked or copied this survival strategy and used it to keep our houses in place and stable. Without strong roots or a strong foundation the plant or home would fall over.
Example Question #3 : Solve A Human Problem Mimicking How Plants Survive
There are no parts of a plant that are similar to something a human uses.
True
False
False
There are many parts of a plant that humans use to solve their own problems and make new items. Rafts, helmets, fencing, and more are all modeled after plant parts.
Example Question #1 : Solve A Human Problem Mimicking How Animals Survive
Motorcycle riders wear special clothing to protect their skin and bones if they crash. This is similar to the _________ on reptiles.
legs
gills
scales
scales
Reptiles have scales and this protects their organs from damage. If a motorcycle rider crashes their special vests, jackets, and pants act like tough outer scales and keep them safe.
Example Question #2 : Solve A Human Problem Mimicking How Animals Survive
The ________ of an animal helps keep it upright and stable. Humans mimicked this solution when we made a tripod.
arms
tail
brain
tail
The tail of many animals keeps it upright and stable when standing on two legs. The tail acts as a third limb to keep it from falling over. The same thing happens with a tripod for a camera or phone. The three legs keep it steady.
Example Question #3 : Solve A Human Problem Mimicking How Animals Survive
Porcupines raise sharp quills on their backs when a predator approaches. Humans can _________ this function to help us survive as well.
approve
mimic
hate
mimic
Humans can mimic or copy the ways animals survive to help us as well. Porcupines raise their quills when a predator approaches to scare them away or even stick them if they get too close. Humans use sharp strips on the ground to pop car tires and warn drivers to stop. We are mimicking animals to solve problems.
Example Question #4 : Solve A Human Problem Mimicking How Animals Survive
Humans have alarm systems with cameras, motion detectors, and lights to keep intruders out of our homes. What features of animals are we mimicking to solve our problem?
Ears and eyes
Noses and feet
Arms and legs
Ears and eyes
Humans are mimicking animals' ears and eyes to help us keep our own houses safe. Many animals have excellent hearing and vision, and this keeps them safe from predators, especially at night. Humans cannot see in the dark, so motion detectors and lights help us to see cameras record what happens so we can watch it. The alarm system acts like eyes and ears to keep us safe.
Example Question #5 : Solve A Human Problem Mimicking How Animals Survive
Humans have made robotic arms that function like the trunk of what large tusked African animal?
Lion
Gazelle
Elephant
Elephant
Humans have mimicked or copied the elephants' trunk to create robotic limbs such as arms. The way the arms move and function is similar to the trunk of an elephant. Elephants use their trunks to grab, eat, drink, and care for their young. This is the same for humans with the robotic arm.
Example Question #6 : Solve A Human Problem Mimicking How Animals Survive
Humans watched ______ fly in the sky for years and dreamed of doing the same. To solve this problem we built ________.
birds; airplanes
dogs; airplanes
birds; cars
birds; airplanes
Humans modeled the first vehicles of flight after the design of birds. The wings and ability to glide or float were copied from birds. The features a bird uses to survive helped humans to solve a problem.
Example Question #7 : Solve A Human Problem Mimicking How Animals Survive
Humans mimic animal features to solve their own problems.
False
True
True
This is a true statement. The shells of turtles inspired the creation of bicycle helmets and elephant trunks spraying water are like hoses. These are just a few examples of human inventions that are the result of copying animals.
Example Question #8 : Solve A Human Problem Mimicking How Animals Survive
Scuba divers use dive equipment and tanks to help them breathe underwater. Fish use _________.
fins
gills
tails
gills
Fish use gills to take in oxygen under the water and survive. Humans use tanks and scuba diving equipment in order to breathe underwater. We do not have the ability to breathe underwater on our own like fish so we must mimic them to explore the ocean.
