Part 1:

Phew!  It was exhausting work, but you just hung all the Christmas lights on the tree at Rock Center.  You are standing back admiring your handy work when all of a sudden the whole tree goes dark!  You search through the tree and realize that a single bulb has cracked and broken.  Your boss wants to replace every strand of lights.  You don't think that it is necessary.  Explain to your boss why just changing the broken bulb should restore light to the entire strand. 

 

Part 2:

Okay, problem averted.  You found the broken bulb and fixed the tree.  How can this problem be avoided next year?  Make a recommendation to your boss about a better system for lighting the tree.

3M and 3K Plant SIPS in the Courtyard

First the potting soil had to be mixed with soil.

The seedlings were arranged in three rows.  Short plants in the front, medium height plants in the middle and tall plants in the back.

Once the soil was prepared, it was put into the planters and covered in plastic.  The plastic will help keep moisture in and weeds out.

Each student got to plant three seedlings in their team's planter.

Finally the students filled up watering cans and watered the planters.

Students also had the chance to make more individual SIPS.  They planted basil and lettuce and delivered the plants to faculty and staff around the school.

Yeah for Earth Day

Last Friday, the Healthy Hunter Committee hosted a thought provoking Earth Day assembly.  To begin, the HCES Green Team of 4th and 5th graders, led by high schoolers Penelope and Jenna, performed a skit on alternative energy and shared their video on solar energy.  Next Steve Ritz from The Bronx Green Machine gave an inspiring presentation on urban farming and growing healthy food and healthy communities. Check out Steve and his students in these two videos.
