Here is a guest post from our science teacher, Ms. Svedlund.

Simple Science of Sand

Sand is one-of-a-kind, like a fingerprint. The sand found on every beach is unique, a product of its local environment. It articulates a story from hundreds to thousands to millions of years of weathering, breakdown, and erosion. Grains have been tossed around by waves or washed through a watershed. Sand tells us information about rock types, shelled organisms, waves, and biota from the region it is found. Beaches are a river of sand, regardless of whether it is found on the slope of an ocean, lake, or stream.

Help us build our story! If you are headed somewhere over spring break and can grab a sample to add to the Lower School science lab collection, we’d appreciate it. We are collecting sand samples from around the world. A good sample is about a quarter of a cup, or about a baby food jar size amount, of dry beach sand – collected in a plastic baggie is great. Thank you, and Happy Spring Break!
