As Trial 1 experiments wrap up, have your students consider what might happen if something were to have been changed in their experiments. By changing one variable, what outcomes can they achieve?
For Trial 2, we hope to see those changes in action and have your students be inspired to try their own original research.
Your students will submit a proposal telling us what they want to do for their original experiment, and real researchers and scientists will review their proposal and provide feedback before Trials begin.
This original research will then give students the opportunity to present their findings at our Student Research Symposium.
Trial 2 Experiment Proposals will be due on December 12th. Feedback will be provided by January 9th. Submit your proposal here.
Novel Crops:
Required for all new teachers, optional for returning teachers
28 day trial
Which selected plant cultivars grow best under our simulated International Space Station conditions?
In this trial, you will grow two of six cultivars new to the GBE program. These will be randomly selected for each school.
Cultivars: Papalo – Butterfly Form, Dwarf Nasturtium – Alaska Mix, Thai Basil – Thai Thai Prospera, Fennel – Hybrid F1 ‘Dragon’, Dwarf Grey Sugar Pea, Amaranth – White Beauty
Fruiting Crops:
Optional for returning teachers
70 day trial
Which selected fruiting plant cultivars grow best under our simulated International Space Station conditions under a longer growth period?
In this trial, you will grow one of three cultivars new to the GBE program. Unlike standard Novel Crops plants, these are grown for their fruits and require a longer growth period for harvest.
Cultivars: Tomato – Micro Tom, Tomato – Heartbreakers™ Dora Red Hybrid, Pepper – Buena Mulata
Neighboring Effect:
Optional for returning teachers
28 day trial
Do select companion plant strategies improve growth outcomes in previously tested cultivars under our simulated International Space Station conditions?
In this trial, you will grow two previously tested cultivars together to determine compatibility. Fennel is notoriously allelopathic, or known to harm other plants’ growth, but our preliminary testing suggests that this amaranth may be compatible.
Cultivars: Fennel – Grosfruchtiger, Amaranth – Garnet Red
Water Stress:
Optional for returning teachers
~60 day trial (two 28 day trials)
Do select cultivars withstand both flood and drought stress under our simulated International Space Station conditions?
In this trial, you will grow a previously tested cultivar under both extreme drought conditions and extreme flood conditions to simulate water stress that may be experienced on the ISS. This experiment is modeled after active Kennedy Space Center research in the Advanced Plant Habitat system.
Cultivars: Round Red
Beets – Early Wonder Tall Top
Fertilizer Placement:
Optional for returning teachers
28 day trial
How do select cultivars respond to adjusted fertilizer placement under our simulated International Space Station conditions?
In this trial, you will compare plant growth with fertilizer placed at the bottom of the pot versus uniformly mixed throughout the growing media. This experiment is based on internal testing to determine what may be causing post-germination failure-to-thrive and led to unexpected results.
Cultivars: Red Romaine Lettuce- Outredgeous, Mizuna
FREQUENT Q&A FOR PARTICIPATING SCHOOLS
Throughout the school year, we will add questions and answers to this list!
When will materials become available for GBE teachers?
Materials will go live on our Shopify on September 15th. These materials are strictly for participating GBE teachers. Training is required in order to participate in GBE. Materials are first come, first served.
How soon will materials be shipped out to teachers?
Once your order is placed through Shopify,it will ship within 4-7 business days. ***There have been several delays with fulfillment, both teams are working hard to ensure your materials arrive soon.
Is it too late to join GBE?
At this time, we are at capacity for new teachers to onboard for the 25-26 school year. Please join our Newsletter list to receive updates for the following year.
Where can I find the instructions for assembling my kit or setting up my experiment?
Why did my kit not come with an SD card?
SD cards came pre-installed in your light panels. Please check the microSD card slot!
Will I be behind if I start my experiment after October 6th?
In the Data Portal, that is an arbitrary date, you can change your planting date to any time and start on your schedule!
