POTENTIAL ISSUES TO RESOLVE

1. Installing the ImageJ software on a Mac --> requires users to download Java Developers Kit; users must then go into privacy settings in Mac and allow permission for the software to be downloaded from the Internet
2. Installing the ImageJ software on a PC --> receive error "could not find javaw.exe in path"
3. What happens if you confuse a left vs right measurement? There doesn't seem to be a labelling tool on the software
4. Sloped surfaces; ie orange peel. In order to level it out, would need to use a knife to thin out the peel which could be a safety hazard for young participants
5. How do we standardize the size of the droplet? Straws can be of different size
6. Veins/indentations on the leaf can help constrain the size of the droplet
7. Do we need to specify if its the underside or top side of the leaf?
8. iPhone 5 SE model's camera produces grainy images that makes it difficult to analyze
9. Even using the same straw - different sized drops were produced
10. It would be best for the droplets to be larger than smaller as it is harder to capture images of the smaller droplets that are not grainy (even with iPhone X) But the larger the drops, the more likely it'll spread out on the surface
11. Ask for raw data, not averages (reduce chance of error in transcribing data)
12. specify part of the plant (ie: leaf, petal)
13. Would there be any benefit in having participants describe the texture of the surface (ie: furry, porous, waxy etc)?
14. When uploading images to Google spreadsheet, use Insert > Image. Not File > Import
15. Add food coloring to the water to increase visibility
16. Levelled image not aerial --> water drop should not be curved
17. Hole-punch the leaf to make it more levelled
18. How to distinguish whether the drop was satisfactory/need to redo

I also found it difficult to distinguish the edges of the droplet from the background of the image, especially at low resolutions. I think this is a source of the large error (10 degrees) in the data we recorded.

Adding red food dye really helped with this.
