Measure the ignition time and the pH of each of the 4 chemical wastes
Write an NFPA report and draw an NFPA hazard diamond, correctly colored for each of the 4 chemical wastes
Write a business letter to the headmaster explaining the dangers of the 4 chemical wastes and how they should be stored or disposed
Performance based grading of students' ability to draw the correct electron dot structure for the type of bond between 2 elements
Hypothesis for types of solids lab explaining why the solids had such different behaviors
