Brief Description

Students will use LEGOs to design a creature that is adapted to life in the ocean.

Lesson Objectives:

To apply engineering problem-solving strategies to creat a sturdy structure with LEGOs that has a least one moving part.

To demonstrate an understanding of animal adapations by designing a creature with features adapted to life in the ocean to help it breathe, eat, move, protect itself, and adjust to warm and cold temperatures.

Materials Needed:

Sea Creatures Design Brainstorming sheet

Sea Creatures Design Worksheet

Our Sea Creature Paragraph planning Worksheet

LEGO kits

  2. Review different types of adaptations that would help different creatures survive in the ocean. (e.g., clam shells for protection, bird’s wings and hollow bones for flight, cat’s whiskers for feeling)
  3. Have each student fill out a sea creature adaptation brainstorming sheet.
  4. Have students get into their groups and combine ideas to make come up with a sea creature that the group wants to design. Each design should have at least one element from every group members original brainstorm.
  5. Students should complete a Sea Creature Design Worksheet as a group.
  6. Distribute kits and allow students to start building.
