Ocean Critters with Shells (K-3)  Students look at shells and learn how to sort and classify them.  K-1 classes learn different adjectives to help describe the different types of shells.  Grades 2-3 will learn how to classify and learn about other ocean critters with shells. Grade 4 would emphasize invertebrates. Students will get samples of shells to start their own collection.   Limit: 1 class,   32 students

The following are activities students will do

1. Sort sea shells based on shape to learn classification
2. Look at shells from India and try to identify.
3.  Read  “Murder in the Mud”
4. Sort shell mixture from San Francisco Bay to find carnivores and herbivores.
5.  Make a gastropod and bivalve chart (make and take)
5. Look through the museum to discover shelled animals

  Structure and Function
All organisms have external parts. Different animals use their body parts in different ways to see, hear, grasp objects, protect themselves, move from place to place, and seek, find, and take in food, water and air. Plants also have different parts (roots, stems, leaves, flowers, fruits) that help them survive and grow. (1-LS1-1)
