Volcanic Ash vs Soil
Did you know that volcanic ash helps plants grow? I learned that! I did an expirement to compare the growth between radishes when grow in soil and soil with volcanic ash. Ash has a lot of nutrience in it and it also holds water. When lava destroys plants, or when the ash sufficates it, it takes up all the nutrience. I did an expirement to see hoe volcanic ash effects the growth of raddishes. I studied the plant growth for one week. The end result was with only soilm the plant only grew to be ten centimeters. With volcanic ash I found out that it grew better. The raddishes grew to be 12.5 centimeters. That's a difference. All in all, I learned that volcanic ash does help plant growth, but, if there is too much ash, over 4 inches, it can poison the plant and anyone who eats it.

I found it very interesting how you used soil with volcanic ash to grow your radish seeds in. It surprised me that the volcanic ash actually helped it grow better than normal soil. I think you did a good job on this on this assignment
