We found that slime mold may have negative geotaxis from the results of our seniors’ experiment.
We want to research slime mold because we were interested in it.
True slime mold

This is Slime mold!!
87.5% of slime molds showed that they have negative gravitaxis.
12.5% of slime molds showed that
they didn’t have negative gravitaxis.
Slime molds mostly moved upward.
It is thought that
they have negative gravitaxis.
After 6 hours
rotated 90 °or180°
Use bigger petri dish
They didn’t go over their path from before.
It is thought that they have a property to avoid going over the same path.
They leave the traces such as chemical substances on their path.
Avoid the path where they cannot expect to get food.
In doing so...
The difference in how the slime molds move may depend on the amount of food and the strength of stimulus （gravity, light, and chemical substance）.
What is the material left behind after the slime mold passes?
Why does the slime mold move to avoid it?
How does the slime mold move when signals (gravity, light, andchemical substance) are changed?
Thank you for
