Amazing Arachnids! An Integrated Curricular Unit For Grades 3-4 By Ruth W. Rose
Arachnids are amazing, but they are NOT insects! • Many people talk about “BUGS,” but that’s not a scientific term. • What they really mean is: • Insect or • Arachnid
Some examples of Arachnids are: • Ticks • Scorpions • Tarantulas • Mites • Spiders • Arachnids are an ancient group of animals, dating back 400 million years!!!
Some examples of insects are: • Ants • Bees • Houseflies • Butterflies • Beetles • Wasps • Preying Mantis • Grasshoppers
Arachnids and Insects both belong to the Arthropod family. • They have similarities, but they also have differences… • Arachnids have 8 legs • Insects have 6 legs • Arachnids have 2 main body parts: • Cephalothorax and abdomen • Insects have 3 main body parts: • Head, thorax and abdomen
HelpfulArachnids… • Arachnids can be helpful! • Spiders help to control the insect population by catching insects in their webs as their prey.
Harmful Arachnids • Bites from the Black Widow Spider and the Brazilian Wandering Spider can be deadly if not treated. • Ticks can carry blood-borne diseases such as Lyme Disease.
Arachnids have made adaptations to live in their environment. • Some spiders catch food (prey) in their webs. Usually their prey is a type of insect. • Wolf Spiders are very large and they live in the tropical rain forest. They don’t spin webs. They jump on their prey to catch it.
More adaptions… • Some arachnids use their camouflage colors to hide in their environment. • Crab Spiders hide inside flowers, waiting to pounce on visiting insects. • Long-Jawed Spiders blend in with the grass. They lay in wait for their prey to walk past.
Now that you know the difference between Arachnids and Insects… • The next time you see a SPIDER in a web, what group of small animals is it part of? • What would you call the HOUSEFLY that the spider caught in its web? • If the SPIDER eats the FLY, what’s a scientific name for that snack?
If you answered… • The SPIDER is an ARACHNID • The HOUSEFLY is an INSECT • The SPIDER’S snack is its PREY……. • ……………YOU’RE CORRECT!!!
