Crustaceans for Kids
Crustaceans are animals whose bodies are made of segments, a tough outer shell, two pairs of antennae, and limbs that are jointed. They can be very large like the North Atlantic lobster that can weigh over 40 pounds, long like the Japanese spider crab with legs up to t12 feet long, or less than a millimeter in length. Crustacean are covered with armor called an exoskeleton. You will learn how these animals molt, behave, reproduce / life cycle, label their body parts (they have three mouth parts), video links, colorful flashcards, and so much more! We’ve included information about lobster, crayfish, fiddler crabs, hermit crabs, shrimp, krill (a keystone species), barnacles, and horseshoe crabs.
Mollusks for Kids
Mollusks are soft, slimy creatures with squishy bodies. Some examples of mollusks include snails, slugs, oysters, clams, mussels, sea slugs, and others. Every seashell you find on the beach was made by a mollusk (including the crustacean hermit crabs live in)., but not all mollusks make shells. Learn how mollusks have a siphon to intake and excrete water, how they have a foot, where pearls come from, the many tiny eyes of the scallop, huge 500lb clams, and how some mollusk like the whelk drill into other mollusk shells. The pdf file include black and white pages filled with interesting information and cute clipart. In addition, you will download colorful flashcards, fact and opinion, mollusk worksheets to label the anatomy, write down what you’ve learned on the report template, or print the colorful flashcards.
Cephalopods for Kids
Cephalopods are a type of mollusk, but since they are so intelligent and fascinating we included a whole section for students to learn about octopus, squid, nautilus and cuttlefish. Amazing aquatic cephalopods can change colors in a split second, change the shape of their body to fit in small cracks, have three hearts that pump blood, powered by jet propulsion, and even make their own ink. In addition to the pages filled with fun facts, you will find printables to label the anatomy, learn the life cycles, complete worksheets, buoyancy science experiment (including recording sheet) and see what you’ve learned with a text. There are 54 pages in this huge pack all together filled with lots of cute clipart that will keep Kindergarteners, grade 1, grade 2, grade 3, grade 4, grade 5, grade 6, grade 7, and grade 8 engaged and learning!
