Lesson 1 | ||
#1 | Do humans have an internal skeleton or an exoskeleton? | Internal skeleton |
#2 | What is the difference between an internal skeleton and an exoskeleton? | Internal skeletons are inside the body, exoskeletons are outside the body. |
#3 | How is an exoskeleton SIMILAR to an internal skeleton? | They both are hard and provide support to the body. |
#4 | What do insects use to take in oxygen? | Spiracles |
#5 | What do plants use to take in oxygen? | Stomata |
Lesson 2 | ||
#1 | Do adaptations happen quickly or over many generations? | Over many generations |
#2 | What is a change in a gene called? | Mutation |
#3 | What is natural selection? | If a mutation helps a plant or animal survive in its environment, it had a better chance to live and reproduce to pass off the gene to its offspring. |
#4 | What is an advantage of seeds that can be spread over a wide area? | They may have less competition for resources |
#5 | Which of the following is true about succession? a. it is unpredictable b. it follows change | b. it follows change |

Lesson 4 | ||
#1 | How many stages are there in complete metamorphosis? Name the stages. | 4 stages-Egg, Larva, Pupa, Adult |
#2 | How many stages are there in incomplete metamorphosis? Name the stages. | 3 stages- Egg, Nymph, Adult |
#3 | How do frogs breathe when they are tadpoles? How does it change when they become adult frogs? | Tadpoles breathe through gills when they are tadpoles. When they grow to be adult frogs they use lungs to breathe. |
#4 | What are some structural adaptations of adult frogs that help them survive? Explain how that adaptation helps the frog survive. | Long legs to help frogs jump. Color helps them blend in to their environment. Webbed feet help them swim. Long tongue helps them catch insects to eat. |
#5 | Compare the difference in life cycle stages of a cat and a frog. | Cat- looks like parents when it is born, grows to full size adult cat. Frog- Goes through metamorphosis: born an egg, grows to tadpole, tail shortens and grows legs to adult frog. |
