Integrated Science · Chemical Reactions Acids, bases and indicators – titration drop by drop A beaker holds an acid or base solution with an indicator already added (litmus, phenolphthalein, or universal pH paper). Students add... Ages 13–14
Integrated Science · Chemical Reactions Acid–base indicators – litmus, phenolphthalein, red cabbage, universal indicator Nine test tubes contain lemon juice, vinegar, HCl, distilled water, salt water, soapy water, baking soda, NaOH and limewater. Students... Ages 13–14
Integrated Science · Chemical Reactions Limestone kiln – calcination and the carbon cycle Load limestone into the kiln and adjust the kiln temperature: below about 825 °C the reaction barely proceeds, but from 900 °C upward... Ages 14–15
Integrated Science · Chemical Reactions Metal reactivity series – dropping metal into solution Choose a metal from the reactivity (activity) series — K, Na, Ca, Mg, Al, Zn, Fe, Pb, H, Cu, Ag, Au — and a solution: dilute HCl or... Ages 14–15
Integrated Science · Chemical Reactions Alcoholic and Acetic Fermentation – Esterification A fermentation vessel holds a glucose solution: switch on the yeast and CO₂ bubbles rise as the ethanol level climbs day by day. The... Ages 14–15
Integrated Science · Chemical Reactions Alkane and alkene molecules – 3D ball-and-stick models Ball-and-stick models of methane CH₄, ethane C₂H₆, propane C₃H₈ and ethylene C₂H₄ spin freely in space; drag to rotate them by hand. The... Ages 14–15
Integrated Science · Chemical Reactions Four Groups of Biological Molecules: Monomers, Chains and Identification Tests Choose a group of substances and watch monomers link together into a long chain: glucose molecules join to form starch, amino acids join... Ages 14–15
