Applying Inquiry and Big Ideas

Be able to describe how a nymph and adult grasshopper are similar and different.

·          The nymph has a shape that is similar to the adult’s body.

·         An adult grass hopper is larger and has wings, but a grasshopper nymph is smaller and does not have wings.

What keeps a fruit from forming seeds?

·         Pollination is needed to make seeds.

·         The flower that made the fruit did not get enough pollen.

Describe what mimicry is and give an example.

·         Mimicry is an adaptation where one living thing imitates the look of another.

·         An example of mimicry is when the Viceroy butterfly looks like the Monarch butterfly, so it does not get eaten.

Describe how defense adaptations of a plant and animal are similar.

·         Both plants and animals can have spines to keep away predators.

·         Both plants and animals can taste bad to keep animals from eating them. 

·         Both plants and animals can be camouflaged in their surroundings to avoid being eaten.
