"The Great Race" or "La Gran Carrera" is an enrichment science experiment to use over three days. This experiment complements the Adelante Unit 8 curriculum on erosion, but it can be done without much prior knowledge of erosion. This experiment has always solidified my students' understanding of erosion.
It is a simple experiment! All you will need is some dirt from the playground, water, ice, and a straw. Plus, students are always excited to see the changes each day.
Over the course of 3 days, students observe three types of erosion: water, wind and ice. This resource is the observation notebook and complete instructions for how to conduct the experiment.
