Question
- we observed the soil to have 30% silt, _5__% sand, and _10__% clay.this classifies the soil as a ______- the data i collected shows the soil to be _5__% silt, _9__% sand, and_19__% clayreasoning - the reasoning is your attempt at explaining how the evidence supports the claim (your answer). some sentence frames are listed below.- the evidence supports my claim because that is what was in the sample- the data supports my claim because our soil was classified as loam__, and most plants prefer loamy soil.using the instructions above, fill out the following table.question: based on the knowledge that most plants prefer a loamy soil, do you think your soil sample would be ideal for growing vegetables?claim (answer)evidence (data)reasoning (how data helps claim)
Brief Explanations
First, classify each soil sample using the USDA soil texture triangle: loamy soils typically have 7-27% clay, 28-50% silt, and 23-52% sand, or fall in the loam/loamy subcategories.
- For the first sample: 30% silt, 5% sand, 10% clay. Calculate the remaining soil component (organic matter is not part of the texture triangle, so total mineral components sum to 100%: $100 - 30 -5 -10 = 55$% is missing, but assuming the given values are the full mineral components, this soil is silt loam (a loamy soil).
- For the second sample: 5% silt, 9% sand, 19% clay. This sums to 33%, so assuming the rest is non-mineral, this soil is clay (not loamy).
Then, form a claim based on the fact most vegetables prefer loamy soil, cite the evidence, and link the two in reasoning.

First Soil Sample (30% silt, 5% sand, 10% clay)
| Category | Content |
|---|---|
| Evidence (Data) | The soil is 30% silt, 5% sand, 10% clay, classified as silt loam (a loamy soil). |
| Reasoning (How data helps claim) | The data supports my claim because our soil was classified as silt loam, and most plants (including vegetables) prefer loamy soil. |

Second Soil Sample (5% silt, 9% sand, 19% clay)
| Category | Content |
|---|---|
| Evidence (Data) | The soil is 5% silt, 9% sand, 19% clay, classified as clay (not a loamy soil). |
| Reasoning (How data helps claim) | The data supports my claim because our soil was classified as clay, and most vegetables prefer loamy soil, which this is not. |
