Erosion lab

What is the difference between weathering and erosion?



Weathering breaks apart the rocks, pebbles or soil. Erosion is what carries them away!

This week we did an erosion lab. What a difference a little plant does when there is rainfall! Check out this photo of some plain garden soil and a house plant after we simulated rain on both. The garden soil was washed away by erosion, and the soil under the plant was protected by the leaves and roots!

Weathering lab!



This week was our first trip down to a real science lab! We had such a great time learning about lab safety and conducting an experiment in groups following the scientific method.
