April 27th- 201- Bike Shelter Update
Mr. P discussed with the Bike Shelter group a new option, to construct the shelter out of pressure-treated wood, based on a design used by the Portland Oregon Public schools. See Bike Shelter Development Guide
It would also be a joint venture between Green Engineering and the Wood Technology program.

April 27th- 101's- Research
The 101's continued to research their Quarter 4 Inquiry research projects- come up with one central question that can be tested, then answer that question.
Conduct a six week scientific inquiry independent research project. This gives students the opportunity to hone in on the skills they have learned during boot camp and the Core 4.
- Weeks 1-2: Create a detailed proposal of what you will research, which answers 3 basic questions:
- What? What is your research topic?
- So What? What will be the impact of your project
- Now What? What are you going to do? Create a timeline of what you will be doing...
Research a topic that could become a new 'Core 4' topic, producing material that other students can build upon.

April 12th-Xplorers- Plastics Recycling Projects
The Xplorers continued on their work to come up with creative ways to upcycle plastics:
Mr. P explaining the plastics shredder:
Experimenting with the injection molder:
Attempt at shrink-wrapping plastic to make a hat:
Pieces of a future frisbee:
Creating a cellphone stand from bamboo:
Attempt at using a hot-glue gun to extrude polystyrene plastic:

April 10th- Xplorers Design Review
Parachute-
Real one would be 25-45' in diameter.
How thick would the material be?
We could test its wind resistance by running.
Frisbee-
Why is a frisbee the shape it is? What role does the lip play in its aerodynamics?
https://www.scientificamerican.com/article/bring-science-home-frisbee-aerodynamics/
Compare to an Aerobie-
How does it work?
Iphone Case-
What type of plastic would you use?
Chandelier-
Hat
Passive speaker for smartphone using bamboo-
Table
Keychain
Upcycling.

April 7th- 101 Check-Ins; Quarter 4 Outline
Reviewed visit to Greentown Labs.
Need self-evaluation sheets from everyone by the end of today- need evidence to support your evaluations.
It is now the start of Term 4-
Need self-evaluation sheets from everyone by the end of today- need evidence to support your evaluations.
It is now the start of Term 4-
- Read Term 4 sheets
- Need to continue your Core 4 project, or, if done
- Scientific Inquiry Project
You have 2 weeks to come up with a proposal-
- 6 minute presentation
- What?--What are you going to investigate?
- So What? Impact Goals
- Now What? What are your specific steps?
Come up with a timeline for the next 6 weeks.
Will produce a scientific poster on your project at the end of Term 4.
If you are continuing with the Core 4--what are you personally going to do?
i.e. Journal articles you will read, what will you build or do?
If you are stuck-- sources include asking Dr. T, Pinterest, Instructables, TED talks.
Proposal action starts May 4th.
Group Check-Ins:
Algae Group:
The algae group restarted a number of bioreactor bottles, with new manifolds for aeration and new airstones.
Improved aeration and air stones, and not over-feeding, has improved growth significantly.
The Algae group will continue working with the algae project- pursue harvesting, oil/lipid extraction, etc.
Questions/Next steps-- Could you keep the algae alive over the summer?
Bikes Group:
Will be working to stabilize the bike frame, and investigating ways to produce continuous power output.
Generator charges battery using solar panel controller( Vellaman 80L4UCN2)- automatically switches load to battery when charged.
Materials Group:
Moving on to mycelium project. Soaked straw substrate in Hydrogen Peroxide to sterilize; will inoculate with mycelium spores.

Left 2 terminals: 12V to inverter( Cobra CPI 480 DC to Ac Inverter)
Center 2 terminals connected to 12V gel-cell battery
Terminals 5 and 7 connected to generator or to solar cells
Materials Group:
Moving on to mycelium project. Soaked straw substrate in Hydrogen Peroxide to sterilize; will inoculate with mycelium spores.
Began building prototype for rooftop garden system.
Aquaponics Group-
Have been replacing plants, adding supports to pea plants; working on building a refilling station,
will begin planning temperature control system.
May move on to bikes. May get fish for system.
