Choosing a earth science project
Earth science works well when you can model a big system in a tray or a jar — erosion, drainage, sedimentation — and measure it accurately.
Earth Science experiments and science fair projects
Hands-on earth science projects covering soil, water, rocks, weather and erosion. Each one lists the exact materials, the time and cost involved, the variables to control and a data table you can fill in — so it works as a class activity or as a full science fair entry.
23 published projects in this collection
What every project includes
A research question and hypothesis, an independent and dependent variable, the variables you hold constant, a materials list with costs, numbered steps, safety guidance and a reproducibility score based on how completely the method is documented.
