Use NaOH in a microscale titration with bromothymol blue as an indicator. Do solubility labs and develop solubility curves. Close syringe with finger on the end and pull out plunger. Given properties of fictitious elements, fit onto table Construct 20-sided element ball with facts about the element on each of 20 triangles. Graph properties such as electronegativity, ionization energy Do a research project on an assigned element, using the library and internet.
Potassium salts can replace sodium salts.
Comb hair vigorously and bring comb near a thin stream of water. The polar water molecules bend toward the comb. Have students explain. Students generate hydrogen and oxygen at the microscale level in a Beral pipette and spark their mixture to see which rocket goes the furthest. Stopper both ends.
