Chase was instructed in the structure of an atom. I explained how to read the periodic table and determine the number of electrons each atom employs. Once she understood the structure we discussed the concept of ions, and when elements lose or gain an additional electron, giving the atom a charge. She completed determining the charge of several examples of ions. We then discussed the neutrons, and isotopes; which is when an atom loses or gains a neutron. I gave her examples of where isotopes are used to understand migration of turtles. We then started to discuss how elements combine to become molecules, how ions and isotopes increase the energy in certain molecules. Finally we discussed the law of conservation of matter, which states that matter cannot be created or destroyed, only changed. We then worked on balancing chemical equations. Chase was given several equations and tasked with working out how to balance the reactants or the products to make the problem true. Homework: Balance some given chemical equations.
