How Soil Affects Pinto Bean Growth

Easy
Science fair project - How Soil Affects Pinto Bean Growth
We're going to explore how different soils affect the growth of a pinto bean. We'll measure the growth of the beans over a six-week period to see which soil produces the best results.

Hypothesis

The hypothesis is that cotton will increase the growth of a pinto bean the most.

Method & Materials

You will label cups with different types of soil, plant pinto beans in each cup, and measure the growth of the beans over a six-week period.
You will need foam cups, pinto beans, potting soil, regular soil, blended soil, cotton balls, a permanent marker, measuring cups, and water.

Results

The results indicate that cotton was the best material for the pinto bean to grow in. This stands out because it was unexpected, as the other soils were expected to produce better results.

Why do this project?

This science project is interesting because it shows how different materials can affect the growth of a plant.

Also Consider

Variations to consider include using different types of beans, different types of soil, and different amounts of water.
