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.

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.

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.

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.

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.

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.

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.

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.

Polar bears are suited to freezing weather. They have thick skin and heavy fur to keep them warm and safe against cold temperatures and high winds. If we wanted to make clothing based on an animal, we should make heavy coats make of thick, fuzzy warm material. If we wanted to blend in with the snow like a polar bear we would even make the coat white!

A knife is sharp and has a blade similar to a sharks' tooth. The shark is a carnivore, which means it eats meat, so its teeth are adapted to help them catch and eat their prey. Humans have sharp teeth but need some help cutting up our food. Knives serve the same function as sharks' teeth.
