Join a group of four kid detectives and help them find out about STEM while developing problem solving, observation and deduction, and investigating skills.

Our four detectives, Farah, Amelia, Mohammad and Sam, have won a contest and the prize is to visit the new deep-sea lab. When they get there they are enlisted by a marine biologist to help count the population of isopods in an are of the sea floor. When they give the scientist their numbers, she tells them that it is not what she expected. The isopod population has drastically declined since the last time they were counted a week ago. What has happened? She explains to them that something may have disrupted the ecosystem and impacted food chains.

As the kids go back into the submersible to take a closer look, they discover an unexpected predator and its presence may be due to the eruption of an underwater volcano heating up the sea floor.
