PS 130 Scientists and Engineers at Work

Kindergarten engineers from K-307 and K-308 are figuring out how to build a class pinball machine.  So far, they have explored how to make a ball start to move (by exerting a force on it, of course) and how to make the ball move as far as we want.

First Grade scientists are figuring out how Spruce the Sea Turtle will survive once she is returned to the wild, even though her predators — sharks — are out there in the ocean.  They have been making models of defenses, such as spikes, shells and camouflage, that help plants and animals survive in their habitats.  The clay is the soft body of an animal or plant.  The black comb is the sharp teeth or claws of a predator that wants to break it into little pieces for lunch.

Second Grade scientists are trying to figure out why a particular tree in the Bengal Tiger Reserve has not been been producing new plants in the past twenty years.  They have investigated seeds and what plants need to grow.  Now they are looking at how the different structures of plants help them get what they need to survive.

Third Grade scientists are investigating non-touching forces.  They are trying to explain how a floating train works.  How does it float without anything even touching it?  To understand better, they have been investigating what objects a magnetic force acts upon, and how they attract and repel each other, without even touching.

Fourth Grade engineers are learning about how an electrical system works.  They are finding out what happens when one part of the system takes up more energy than it needs to, and how to solve that problem.

Fifth Grade food scientists are learning about molecules and chromatography — how scientists separate mixtures.  In the meantime, they are exploring many different


models of chromatography and how to best communicate about how it works on the molecular level.

Third and Second Grade scientists got to board the Bio Bus, thanks to the ever-generous PTA.  Here they are, getting a close look at themselves and some daphnia.  Oh, and, writing on the walls — it’s ok, the bus is designed for such shenanigans!
