Typically, in these competitions students are requested to solve theory and experimental problems. The latter are usually challenging experiments performed with relatively low-cost equipment. However, these Olympic experiments rarely have widespread dissemination, despite their great potential to be used back in a high-school context, in original form or in an adapted version.<\/jats:p>\n                  <jats:p>\n                    A comparative study of the students\u2019 learning gain of the classical capacitor discharge experiment, a compulsory experiment for Portuguese K-18 (pre-university) students, with an Olympic inspired version using the LM555 timer circuit was performed in seven Portuguese high-schools, involving 175 students.
