Soil science — types, structure, nutrients

What you'll learn

1. 1

   Soil is like a living sponge — it holds water, air, and tiny bits of broken rock called particles.

2. 2

   Grab a handful of soil in your mind. Squeeze it — does it crumble? Feel the texture? That tells you if it's sandy, silty, or clay.

3. 3

   Which soil type has the biggest particles you can see?

4. 4

   Let's figure out the soil structure — how the particles clump together.

5. 5

   Now you're a soil detective. Drag the soil type to match its texture: sand = gritty, silt = smooth, clay = sticky.

6. 6

   What does good soil structure help plants with?

7. 7

   Which nutrient is MOST important for green leaves?
