In April, Sally MacLaughlin’s second grade class in Lincoln, Maine was busy studying the ocean biome. They read the book, “The Bumpy, Lumpy Horseshoe Crab” as part of this unit, and watched the two videos from the janicepetrie.com website. The second graders enjoyed all three, and were surprised that the horseshoe crab’s closest relatives are scorpions and spiders. The book was also used as the focus point of their classroom bulletin board. Because Lincoln isn’t a coastal community, Sally used a molted horseshoe crab shell to teach students about horseshoe crabs. This ocean unit culminates with their spring concert, that has an ocean theme as well.
