We had a fun week exploring crabs. Students learned some fun facts about these creatures including they have eight legs and two pincers. (I had to convince the students that they are indeed called pincers and not pinchers.) We also learned that the largest crab is as big as a person! (eeewwwww!) I showed students this video on hermit crabs….so interesting!

On Tuesday, students participated in an experiment where they used the three types of claws that crabs can have: scooping, grasping, and scraping. They tried to “eat” different types of food to determine which type of claw worked best for them.

Students try collecting food using a scraping claw (small spoon), like that of a shore crab.

Students use a scooping claw (ice cream scooper and large spoon) like that of a porcelain crab.

H. uses grasping claws (chopsticks, salad tongs, clothespin), like those of a hermit crab.

After each student used each type of claw, we came back together to discuss our findings. Watch the funny video below. The crab eyes on the headbands are super wiggly!

During Friday Fun, students made a crabby crabwich. How cute are these?!

We changed the recipe a bit adding blueberries instead of olives for the eyes,  strawberries instead of peppers for the pincers, a slice of mandarin for the mouth instead of a slice of radish…we also added the CORRECT number of carrot legs…EIGHT!!

The added bonus fro this activity for me was that the students ate almost ALL the crab pieces! Looks like a good, healthy snack!
