LS3: Heredity: Inheritance and Variation of Traits

Activity or Mini-Lesson:

Surviving & Thriving in Cold Water

Anywhere in the world, the temperature of most water in the deep ocean is only 39 degrees F. Most seafloor creatures live at that temperature at all times. Most animals ROV Hercules encounters on the seafloor are invertebrates, which do not regulate body temperature like mammals. However, animals that infrequently visit the deep sea, like deep-diving whales, must have adaptations to handle the cold temperatures.

Activity or Mini-Lesson:

Adaptations Of Octopuses

This lesson uses the 5E method (Engage, Explore, Explain, Extend, Evaluate) to dive into the lives of octopuses and how this animal group has evolved over time to adapt to their environments. With a hands-on demonstration, students will mock up octopus ink and examine how octopus use camouflage on the seafloor. 

STEM Learning Module:

Any Fin Is Possible

Students will learn about a variety of fish adaptations for marine and freshwater environments. Students will design a fish using custom printable body plan variations and justify the adaptation choices given to the species with information about how that fish has evolved to be successful for its environment.

eDNA & Coral ID Classroom Warm Up

Classroom Warm-ups: Kick-off any lesson with these one-page, observation-building, problem-solving STEM prompts — whether or not you’re teaching an ocean topic.

By detecting environmental DNA (eDNA) in collected water samples, scientists are able to sequence and identify coral species both known and new to science.
