High School (14-18 years)

matchIn this activity students walk in front of the motion detector to match the given distance vs. time graph Activity Match the graph (demo)
foodThis is an activity in which different student groups can investigate different items of food. A sample of a food of known mass is burned, heating a calorimeter. Students record the temperature of water heated in the colorimeter, calculate the energy transferred to the water, and hence estimate the energy present per unit mass of food. Activity Energy content of food (demo)
reactionIn this activity students measure the temperature change in four chemical reactions and classify the reactions as exothermic or endothermic. Activity Endo- and exothermic reactions (demo)
precipitationIn this activity students investigate the rate of reaction between thiosulphate-ions and hydrochloric acid. By using an turbidity sensor to measure the amount of light that passes through the mixture, the reaction rate can be determined. The reaction order can also be calculated from the results. Activity Rate and order of reactions (demo)
coolingIn this activity students record temperature during a cooling process of hot water and check the validity of Newton's law of cooling for the collected data Activity Newton’s law of cooling (demo)
