After agreeing to document the changes in our dead plants columns, we are starting to see some amazing things happening!
Appearance of Mold/Fuzzy Stuff/Other Colored Things
Size Change and Color
Worms Appearing to Get Larger and May Be Pooping?
Plant Growth (But differences between the plants)
When we sat in a scientist circle and tried to explain the causes for each of the changes in our columns, we started to realize that too many factors, or variables, could be causing the changes. This also opened up a slew of new questions regarding worms, mold, and plant growth, which we will need to address later (we added new investigation ideas like research and new plant investigations).
For this reason, we decided to run new investigations testing only ONE variable at a time. This way, we could pinpoint if that particular variable was making any change. We agreed not to test this with worms, as that wouldn't be kind to put them into closed containers without access to air. But we also had the idea to record the weight of the jars to gather any mathematical evidence for changes.
We're testing the following variables:
1. Size
2. Squished
3. Soil
4. Sand
5. Skin
6. Water
7. Heat
8. Cold
9. Light
10. Dark

We've already got data in after just one day, and we're noticing the appearing of things yet the weight in the containers is remaining unchanged (or 0.1 gram b/c our scales may experiencing rounding errors). This is super interesting to us that mold can appear on our plant parts yet the weight stays the same...
We agreed we needed to focus on mold next! What exactly is it? How does it relate to dead stuff?
