It’s a wonderful winter for 7th grade scientists to learn about weathering and erosion, as the rains that came to San Diego have given us lots of examples to explore.
On Tuesday we set out to do just that. We collected background information and viewed the coast to cactus and California’s water exhibits at the San Diego Natural History Museum.
At Sunset Cliffs Natural Preserve the students explored the effects of weathering and erosion in an area that is very susceptible to a changing landscape. We got to see how water, wind, waves, salt, plants and animals are changing the rocks and overall form of San Diego’s cliffs and beaches. Students had the chance to observe the action from the tide pools, while also exploring the ecosystem and the effects that weathering and erosion have on the organisms. It makes a dramatic impression when you are standing by areas of cliff that are undercut by waves and heavy from rains with nothing to support it underneath. We then took in the view from the top so that the picture we have is complete and rich.
Overall though the hundreds of sea hares, a type of sea slug, that we found and returned to the water stole the day!
