Codes
- A4sError code+ Columns on physics demonstrations (E.g. success and failure stories)
- Q2Error codeThe question to be resolved during the interview is presented at the beginning. Three different types of pumps are presented and it is stated that it is impossible for the second one, a suction pump, to raise water above a certain height (which is not given at this stage). The student is then asked why; all the following experiments are designed to develop a systemic understanding of this phenomenon
- Q3Error codeFirst, the suction pump is illustrated experimentally using a syringe. The student is asked the series of questions Q1-Q5, beginning with Q1 : “What will happen if the syringe piston is pulled?”
