Aquaponics:
Hi!
This week Jack and I have been brainstorming lighting ideas. We have been researching lighting that would be effective and easy to hang. Our main problem has been price. All of the best lights, as you could expect, cost a lot of money. Another problem we have been experiencing in how to hang the lights. We currently have two plans.
One plans is to use metal pipes on the side of the tank with a connecting pipe across the middle. we would then hang lights from either steel wire or metal chains. This plan would leave us with height restrictions for the lights and we don't know how structurally sound it would be.
The other plan is to hand a strong chain from wall to wall over the tank and hang one large light directly over the grow bed. This plan would work best with a powerful, large light to make sure that the light would hit the plants even from a greater height. The issue with this plan is that it would mean drilling and securing into both a concrete and plaster wall.
Neither plan is currently perfect, but hopefully we can continue to workshop the ideas until we reach something that will work.
Bye!

Bike Group:
This week our main goal was to fabricate our bike shelter with our 3d printer. We tried for a few days to do it but ended in failure in each attempt.
Our next step are to make a model of the bike shelter our of physical materials. The one disadvantage is the less than perfect scale of our materials.
We are also starting to assemble the list of materials we might need for the shelter.

Aquaponics- Tank section:
Our grouping has shifted a little this week but we are all still on task. Currently, Eric and I are breaking down the pallets for the outside of the tank. Our final system is coming along nicely with Spencer working on the automatic fish food dispenser and Jack and Maddie working on the main system design. Our plan is to stain and/or paint the pallet boards then put them onto the outside of the tank.
Aquaponics- Fish Feeder:
The automated fish feeder is done mechanically and is completely programmed. We are still working on some small jamming issues but other than that it is working. The delay in the program on an arduino is accurate enough over a day. Other than that, things are good.

Plastic Recycling-Toby:
Newer Penny board has a slight curve in it which improves the performance. However, difficult to make curve because the fusinizer is flat. Discussed options for making shapes- see http://steamcurriculum.weebly.com/longboards.html about Dartmouth longboard project, using vacuum sealer around shaped form.
One possibility might be to fuse plastic into thinner sheets( 1/8") then bend over a metal form heated from below.

Mr. P-- Discussed school budget issues- can't obligate new expenditures. Green Engineering is sort of part of science and sort of part of CTE. Limited funds for aquaponics and algae projects for 101's.
Look for positives- give students experience in raising own funds- discussed using https://www.gofundme.com/:
Classroom Supplies
From books to technology and more, a GoFundMe crowdfunding campaign can help you get the supplies every classroom needs.
February 10th--
Field Trip to Greentown Labs- https://www.greentownlabs.com/
We’re comprised of passionate entrepreneurs solving big energy and environmental problems. Our startups represent the engineers, business experts, physicists, chemists, botanists, roboticists and other industry pioneers who are working day and night to build the next product to address society’s environmental challenges.
At our facility in Somerville, MA, just 3.5 miles from downtown Boston, we offer 33,000 sq. ft. of prototyping lab and co-working space, a shared machine shop, and an electronics shop. Members of our community are immersed in a growing network of local, national and international cleantech resources and fellow entrepreneurs. We host more than 150 events and 10,000+ visitors every year, and those numbers continue to climb.

What can we have people donate?
What about a PTSO grant for STEM?
Eric-
Solicit local companies for grants for store credit, publicity, etc.
We need to have a positive culture.
