STEM concepts
We will be using a store bought automatic hose timer that regulates the amount of water that the hose, in this case the globe will disperse. We will need to figure out how to program this timer to function easily with good directions, so there is no user error. We will also need to find a way to attach the glass globe to the post. We want to create a screwed in edge like a mason jar, so the globe and the post will easily attached and de attach so the globe can be filled up efficiently. We will contact Jeffrey Auxer, who has a glass bowling company so we can create a unique and creative product for our design. Finally, we will assemble our design using our glass globe, automatic timer, and PVC pipe post to create our plant waterer.
Prototype stages
Construction Stage
- First we begin by gathering our parts. We are planning on creating our globe by blowing it out of glass. Once we have the glass globe we will insert threads near the bottom so we are able to screw it into the timer and the rest of the product. Our timer will be store bought, and we will set it to meet the specific plants need (amount of water). Once we can assemble the glass globe, to the programed timer, we will create a post that sticks into the ground and will transport the water to the soil when the timer allows. The water will be released and stopped by the timer and when the water is not flowing the soil will have time to settle, therefore it will not clog the post.
Testing and Data Gathering Stage
- After we have developed our prototype we will perform two trials of testing. We will have to test how long we will want the timer to run and make sure it is functioning, so that the water will be released to the plant. This amount of time will depend on the diameter of the valve so that the flow of water will not be too strong or release too much water in the limited time making sure that the globe will not run out of water too fast. We will also do research and experiment with how much water specific plants need to be watered everyday, to determine the size of our globe.
Experts
Our expert, Mr. Trevor Hill is now the vice principal of Stephen Decatur High School. Mr. Hill previously taught gateway classes, which was a STEM based, introduction to engineering course. Mr. Hill has various knowledge and education of engineering concepts and design criteria and can guide us through the design process.
