Weathering is the physical breakup of rocks, and is often confused with erosion, which is the removal of rock by gravity, wind, and water once it has weathered. This confusion is understandable because they are often intertwined. There are two types of weathering: physical and chemical. Physical weathering breaks the rock into smaller pieces, but the components remain virtually the same. An example might be ice expanding a crack on the side of an arch. Each time the water freezes, the crack gets bigger, but both pieces are still sandstone. Eventually, the piece falls out of the arch, which is erosion. The piece is still sandstone, just smaller and no longer connected to the arch. National geographic science magic kit Interested in joining our STEM Club?

Olfactory Indicators: There is no doubt that science — and therefore, science education — is central to the lives of all Americans. Never before has our world been so complex and scientific literacy is critical to making sense of it all. Science is also at the heart of America's ability to continue innovating, leading, and creating jobs for the future. That’s why all students, regardless of whether they pursue college or STEM careers, should have access to high-quality K–12 science education (NGSS.org., 2013).

What an exciting age to be a young scientist! 3rd grade science is a fantastic time to get engaged in all kinds of science projects that explore the living world and how things work! There are so many great skills that kiddos in this age group have already been working on and will continue to develop as they explore, investigate, and discover through hands-on science experiments for 3rd graders.
