Build an atom out of protons, neutrons, and electrons, and see how the element, charge, and mass change. Then play a game to test your ideas!
CK-12 Chemistry Đ Second Edition covers: Scientific Method; Matter; Atomic Structure; Elements & Their Properties; Chemical Reactions; Stoichiometry; Chemical Kinetics; Physical States of Matter; Thermodynamics; Nuclear & Organic Chemistry.
This is a self-contained book-on-the-web course on basic astronomy, Newtonian mechanics, the sun (and associated physics), and spaceflight and spacecraft. covers elementary astronomy, Newtonian mechanics, the Sun and related physics and spaceflight. Also included are a Spanish translation, 46 lesson plans, a short but complete math course (algebra + trig), teachers' guides, glossary, timelines, 345 questions (current tally) by users and their answers, over 100 problems to solve, and more.
How did scientists figure out the structure of atoms without looking at them? Try out different models by shooting light at the atom. Check how the prediction of the model matches the experimental results.
Our understanding of atoms has been formed through decades of experimentation. In this activity, students learn about the historical developments of atomic theory while labeling the new discoveries.
