Feb 8th- Xplorers- Chair Design

Day 2 of Chair Design- students are to build three(3) miniature prototypes of chair designs.

The variety and originality in the designs was impressive!

February 8th-201's/301's

Soap samples from Soap Group:

Discussion about forming an LLC in Massachusetts.

/* Blink without Delay

  Sample code- blinks 3 LEDs at 3 independent rates
  using millis() function

// Set Pin numbers:

const int redLED =  13;// the number of the LED pin
const int greenLED = 11;

// The value will quickly become too large for an int to store

// interval at which to blink (milliseconds)

Discussion of newspaper articles in TAB and Newtonite about bike shelter project

February 8th- 101's- Bikes, Plants

Bikes Group-

    successfully mounted generator, added friction tape to get better speed. Motor puts out > 13V when bicycling.

Plants group-

Worked on getting air-pump system working. Used snoop to troubleshoot small leaks.
One bicycle pump is broken. Suggested that all joints be epoxied, and that they use a small container so that the system will be more portable.

Algae group-

Algae seems to be growing well. Discussion about how to extract the oil from the algae- French press??

Aquaponics-

New lights seem to be working well. pH question.

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.
