Since gravity is negligiblecompared to other forces, you would feel like you were The science of atoms and molecules is the basis of biology. Atoms and molecules are also central tomodern chemistry, earth science, electronics, nanoscience,forensics, and all the interdisciplinary fields like biochemistry, space weather, and plasma dynamics. a reordering of the introductory sec-physics before chemistry, which is thenfollowed by biology.

To help, we created a sequenceWorkbench in middle school through college, we foundbased learning for a long time. By going deeper, it Creating a better introduction to science We introduce the all-important forces between atoms,which give rise to a potential energy, and the centralconserved.

As part of this project, we are creating a Molecular Concepts Inventory student understanding of the science of
