In this electrochemistry activity, learners will explore two examples of electroplating. In Part 1, zinc from a galvanized nail (an iron nail which has been coated with zinc by dipping it in molten zinc) will be plated onto a copper penny. In Part 2, copper from a penny will be plated onto a nickel.

Students will observe and perform experiments with the elements sodium, potassium, calcium, magnesium, sulfur and phosphorus. Conclusions will be made about trends down groups, across periods and relating to acidity/basicity of metal oxides vs. nonmetal oxides

This activity is a puzzle where students organize samples and look for patterns in order to predict properties of missing puzzle pieces. The students then relate their experience to the historical development of the Periodic Table and the ways that the Periodic Table can be used to predict the properties of the elements.

As part of the introduction to the Periodic Table of the Elements, students will be introduced to the idea of atoms, molecules, and compounds. The physical manipulation of marshmallows (atoms) and toothpicks (bonds) will create a visual representation of the molecular structure of water. A second step requires students to create a second molecule using similar materials and using the Periodic Table as a reference point.

Add different salts to water, then watch them dissolve and achieve a dynamic equilibrium with solid precipitate. Compare the number of ions in solution for highly soluble NaCl to other slightly soluble salts. Relate the charges on ions to the number of ions in the formula of a salt. Calculate Ksp values.

Test the pH of things like coffee, spit, and soap to determine whether each is acidic, basic, or neutral. Visualize the relative number of hydroxide ions and hydronium ions in solution. Switch between logarithmic and linear scales. Investigate whether changing the volume or diluting with water affects the pH. Or you can design your own liquid!
