Spin the wheel to select from four sets of themed activities (Moving like Food, Moving like Animals, Playing at the Park, or Going on a Picnic). Each wheel includes various physical movements that the player randomly selects by pulling the lever. Wiggle like spaghetti, jump like a frog, swing a baseball bat… how will the app ask YOU to move?

In this lab you will find a bottle of liquid ammonium chloride, a bottle of solid ammonium chloride, a bottle of sodium hydroxide, a bottle of sulfuric acid, and indicator paper. The objective of this practice is to verify that the ammonium chloride behaves as an acid or as a base against sulfuric acid and sodium hydroxide. The pH, concentrations, and reaction constants must be measured to obtain an amount of ammonium sulfate.
