Science Sunday – Creepy Crawlies

Science Sunday: Creepy Crawlies

Although they may look strange to humans, creepy crawlies such as insects, millipedes, spiders, snails and slugs do a great deal to help the environment. They:

fly close upPollinate many fruits, flowers, and vegetables.
Produce honey, beeswax, silk, and other products used by people.
Prey on and reduce pest populations of other insects and weeds.
Act as decomposers, helping to break down and dispose of wastes, dead animals, and plants.
Support the food web by acting as a food source for amphibians, reptiles, birds, and mammals. People in many cultures also eat insects (including cicadas, locusts, mantises, grubs, caterpillars, crickets, ants, and wasps) since they are an important source of protein, vitamins, and minerals.

See if you can answer these questions using the resources linked below:
(This type of investigation is called a “webquest”, and you often learn loads of other information while searching for the answers to specific questions.)

snailName three or more features of an insect. How do insects differ from other animals?
Although “centi” means “100”, how many legs do centipedes actually have?
Entomologists (scientists who study insects) often have many years of education. Look up an insect scientist and see what kinds of college and graduate school degrees they have earned. (Great resource:
Where do snails live and when are they most active?
How do centipedes and millipedes differ from one another?
Choose a “scary” insect and write down three facts about it.
Snails and slugs belong to the same “family” of animals. What is that family called? (Hint: the family name starts with an “M”)
Insects do not give birth to babies the same way people and mammals do. Create a diagram or write a few sentences explaining the lifecycle of an insect.
