Earlier this year, we visited the Gowanus Canal with Barbara and thought about how it has changed over the last 400 years. The kids were sad about how dirty, polluted, and downtrodden our local waterway is. After a year of learning about water and environmental issues, they were ready to work on a small part of the solution!
Their year-end science projects are “floating islands” to help the Gowanus. At this year’s Ecorama celebration, our class presented their “floating island” prototypes.
These projects were inspired by a visit to look at Balmori Architect’s GrowOnUs island in the Gowanus (pictured above, and originally assumed by the kids to be a “trash island”).
Thank you Emmy for the Ecorama pictures; thank you Barbara for teaching us science!
We took a break from studying water to experiment with electricity. How do you make a lightbulb light up? What’s a circuit? Are fingers, popsicle sticks, and thread conductors? These were just some of the questions we explored over three days.

Look, we made a switch!

Better late than never! Early spring trip to the Ridgewood Reservoir. Built in the 1800s, Ridgewood Reservoir still played an important part in keeping Brooklyn residents hydrated as recently as 1959. Originally, water that was stored in the reservoir traveled by aqueduct to steam-powered pumping stations!
Here are teams of engineers trying to design a successful aqueduct using straws and tape.
Lola’s face = the thrill of success!
Once they got their little aqueducts to work, the kids banded together to build a GIGANTIC aqueduct on the stairs.
We have spent the better part of a year learning how we can do things for our waterways. Now we are learning about all the Work (capital W!) that waterways can do for us! This week we experimented with water wheels. Barbara set the challenge of designing an efficient water wheel.
Which design needs the least “water power” to lift a crayon?
Our science and social studies work are truly at an intersection now!
Waterwheels were used in colonial mills (sawmills, gristmills, and more). Windmills were some of the early technologies used by the Dutch (and other cultures) to accomplish large-scale projects. In the Netherlands, windmills actually did the work of draining swamps to turn them into usable, stable land. The earliest known drainage mill is from 1414!
