"weather"

Conifers come in all shapes and sizes — and so do their cones.
Includes: 6 pine cones, 6 spruce cones and 6 cedar cones.
*Pine cone factoid: Pine cones can forecast the weather! In dry weather, the scales dry up and open out. If they start to close up, wet weather is coming!

Useful for weathering and erosion, soil formation, porosity and permeability, or other general earth science labs.
