Feb 3rd- GRNG 101's-

Materials Team-

Working on watering system:

Bicycle Team-

working on remounting generator.

Aquaponics- discussion of Mycorrhizae

Algae-

a lot of growth stuck to bottom of jar.

Will need to figure out how to extract water- use a French Press?

Feb 2nd- 201's and 301's- Bike Shelter Presentation, Learn Launch Prep

The bike shelter team presented to recycling officials from the City- precedents and prototypes:

They also showed off the Aquaponics system- tanks and electronics:

Feb 2nd- 101's- Algae

The algae are growing much better:

Jan 31st-Xplorers- Paper Chairs

Paper Chair Prototypes (2 Class Periods)

1.     With your group brainstorm places in a house that you would have a chair. (5 min)

2.     Pick two of the locations from above and brainstorm requirements (Not Solutions) for a chair in that space. (5 min)

3.     Full class brainstorming session. (5 min)

4.     Create 3 prototypes, each for a different location, using cardboard and materials from the prototyping bins.

Jan 30th- Xplorers-Term 2- Paper columns

Paper Columns (No Scissors!)

Iteration 1:

With 5 sheets of paper and 1 foot of tape build a structure that will support as much weight as possible. The weight must be at least 8.5 inches off the ground. You may not cut the paper!

Iteration 2:

Repeat iteration 1, but make design improvements to see if you can hold more weight.

Jan 20th- Xplorers- Last Day of Term

End of Semester One.

Discussed Greengineering 101, practicing the research piece. Discussed incorporating suggestion into prototype design.

Finished Bike Shelter prototypes:

Jan 20th- GRNG 101's- Weekly Updates

New algae and growth media ordered-- due in on Tuesday.

End of the term- need grading rubrics submitted; permission slips for Feb 10th field trip.

Materials Group-

Joelle- planters outside-- will need more in spring

Am doing research on mycelum--will present several methods of growing it.

In the past students have used glove bags to keep it sterile.

Mycelium can be stored in the Science department refrigerator.

Bikes Group-

Removed the DC motor from the treadmill that Dr. Tupper and Mr. Peloquin got.

Puts out about 6 volts when spun manually. Will be trying to make a friction connection to the bicycle.

Algae Group-

Algae needs less air flow. May have been over-fed. White cloudiness- needs to be disinfected. Have ordered growth media with new algae from Connecticut Biological. Need to sterilize the bottles when setting up the new system.

Aquaponics System-

Need to measure levels of nitrate and ammonia, etc.

What is a reasonable goal to achieve this year- a portable aquaponics system.

Discussed adding automatic controls.
