The Starting Box is a simple design for a mobile greenhouse. The greenhouse is designed to house 150 Red Solo cup plant experiments. Each experiment will be take up an estimated 66.8 cubic inches plus the height that the plant will grow. Keeping in mind the greenhouse should be functional within a classroom, the team decided to make The Starting Box approximately 4 feet long, 2 feet wide, and 5 feet tall. These dimensions make the greenhouse small enough to fit in the client's classroom but big enough to comfortably house all of the students experiments.

Abstract
The Starting Box is a creative design of a mobile greenhouse. The design team, the Four Tall Redwoods, has designed and built the greenhouse for the client, Zane Middle School. The Biology teacher at Zane Middle School, Betsy Elkinton, requested The Four Tall Redwoods build an easy to transport and use greenhouse for her 7th graders spring experiments. The Starting Box enables the plant experiments to grow in desirable conditions. The plant experiments housed in the Stating Box are Red Solo cups with soil and seeds placed inside each one.
Background
The Four Tall Redwoods team was brought together through Humboldt State University’s Engineering 215 course -Introduction to Design, instructed by Camille Penny. Zane Middle School requested that one design team from class construct a mobile greenhouse in an effort to assist Biology lessons. The Starting Box will enhance the biology student’s learning experience of how the plant life cycle works.
Problem statement and criteria
The objective is to design and construct a Mobile Greenhouse to help educate 7th grade students on the plant life cycle as well as help them gain an understanding of how a greenhouse works to provide the necessary components, such as sunlight, to a plant for growth.
The top four criteria for The StartingcBox mobile greenhouse included safety, durability, portability, and cost. Safety was the most important criteria on the list. Any safety concerns brought up were quickly taken into consideration and improved upon. The materials utilized in the construction of the Starting Box had to be safe and durable in order to withstand being handled by Middle School Students. Also, considering that students of the ages 12-13 are usually not capable of moving heavy objects, the cart had to be of an appropriate weight to be easily moved around, and be stable enough to withstand tipping. Cost was also a criteria, however, it ranked low due to team willingness to go over budget.
| Criteria | Constraint | Weight |
|---|---|---|
| Safety | Must be safe for student use | 10 |
| Durability | Durable enough to withstand frequent handling by students | 6 |
| Portability | Capable of transporting experiments
Easy maneuverability about classroom Practical for students to access experiments |
9 |
| Cost | Materials should be obtained either free or purchased at low cost. | 6 |
Description of final project
The Starting Box is a simple design for a mobile greenhouse. The greenhouse is designed to house 150 Red Solo cup plant experiments. Each experiment will be take up an estimated 66.8 cubic inches plus the height that the plant will grow. Keeping in mind the greenhouse should be functional within a classroom, the team decided to make The Starting Box approximately 4 feet long, 2 feet wide, and 5 feet tall.

Included in the design is easy accessibility for students to handle their projects via racks that are able to slide out of the framework. Lastly, a storage shelf was added below the experiment shelves.
How to use and maintain the box
Costs
The materials used to construct The Box were either donated to the Four Tall Redwoods Team or purchased at ACE Hardware. Using reclaimed lumber to build the frame of the greenhouse and donated greenhouse plastic, a total of $105.00 was saved. The items purchased for the final project include paint, paint brushes, wheels, lumber, plywood and a pack of screws.

Discussion and next steps
After construction is complete, the mobile greenhouse will be delivered. The Starting Box will be housed in Betsy Elkinton’s classroom and wheeled into the sun when in operation. The experiments themselves can be placed on shelving within the greenhouse. The shelving is spacious allowing for the students experiments to grow up to a foot high without being disturbed by the roof or shelf above it, giving each experiment plenty of room to grow.
