Example Question #9 : Solve A Human Problem Mimicking How Animals Survive
Which animal should we mimic or copy if we want to create clothes to keep us warm in the winter?
Snake
Polar bear
Parrot
Polar bear
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!
Example Question #10 : Solve A Human Problem Mimicking How Animals Survive
Sharks have very sharp teeth used for eating meat. Which kitchen tool is like a sharks' tooth?
Whisk
Spoon
Knife
Knife
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.
Example Question #1 : Observe How Plant Offspring Are Similar To Parents

roots
stems
leaves
stems
Adult plants and their offspring (baby plants) are both similar in that they use their stems to carry water and nutrients through the plant. Stems also hold leaves up and keep the plant held together.
Example Question #1 : Plants Similarities To Their Parents
Plant offspring are similar to their parents, They both have _______ that absorb water from the soil and keep the plant in place.
roots
leaves
flowers
roots
The roots of a plant collect and absorb water from the soil. They also keep the plant anchored in place. Adult plants and their offspring (baby plants) have this same structure.
Example Question #1 : Observe How Plant Offspring Are Similar To Parents
The ________ of both baby plants and adult plants collect sunlight to make food.
roots
flowers
leaves
leaves
The leaves of a plant collect sunlight to make food. Adult plants and their offspring are similar in this function and structure.
Example Question #2 : Observe How Plant Offspring Are Similar To Parents
Adult plants are fully-grown. Plant offspring are ___________.
old
ugly
babies
babies
The term for a baby plant (or animal) is offspring. They are similar to their parents in many ways and share the same functions and many features.
Example Question #2 : Observe How Plant Offspring Are Similar To Parents
How are baby plants like their parents?
They are exactly the same in all ways.
They look very similar, just smaller.
They are very different from their parents and are not alike.
They look very similar, just smaller.
Baby plants are similar to their parents in a number of ways. They have similar features including leaf shape, color, and appearance. The plants will have the same parts as their offspring which are used for the same functions. Many baby plants are just miniature versions of their parents.
Example Question #3 : Observe How Plant Offspring Are Similar To Parents
Plants are very much, but not exactly, like their parents.
True
False
True
This is a true statement. Mature plants and their offspring have many things in common leaf shape, leaf color, vines, stem shape, and stem color. A baby plant can be matched with its parent based on the way they look. They are usually just smaller versions!
Example Question #3 : Observe How Plant Offspring Are Similar To Parents
How can you tell if an adult plant and a baby plant are related?
You can never tell if a baby plant and adult plant are related.
You can look for things like leaf shape, color, and vines to see if they match.
You can look to see if they have the same exact flowers.
You can look for things like leaf shape, color, and vines to see if they match.
Adult plants and baby plants (offspring) will look very similar when related. Their leaf shape, color, vines, stem shape, stem color, and overall appearance will be very alike.
Example Question #4 : Observe How Plant Offspring Are Similar To Parents
