Determine what factors make a hot air balloon or a helium balloon float Student Instructions: 1. Why does a hot air balloon float even though it is so heavy? Hot air balloons float because the buoyancy force of the hot air is more that the

Measurement of reaction time Measurement of reaction time Aim of the experiment To record reaction times to visual cues using the iworx equipment To compare and contrast the reaction time when provided randomly vs. fixed time intervals‚ and upon repetition. Introduction Our bodies react appropriately to changes that occur in the environment during our day-to-day activities. When responding‚ an external stimulus has to be detected by one or more neurons. These then

Height of Ball Drop v/s The Depth of the Crater | By Tejas Shah‚ IBDP Year 1 | | | | | | | * Aim- To find the relationship between the depth of crater and the height from which it is dropped. * Research Question- Does the height from where the ball is released affect the depth of the crater. * Hypothesis- If we increase the height of the drop of the ball; the depth of the crater would increase. This is because as there is loss in potential energy subsequently there

Measurement of Capacitance using Arduino – An Interrupt-based Approach: Part I SAIKAT PATRA‚ SHIBENDU MAHATA Introduction Capacitive sensors are widely employed to measure various physical and chemical process parameters such as displacement‚ acceleration‚ thickness‚ force‚ pressure‚ stress‚ level‚ and humidity. The measured value of capacitance is then calibrated in terms of the process parameter for indication and/or control applications. This project presents an interrupt-based approach by

Independent Assessment Physics Lab (SL): Cantilever Flexion Cherno Okafor Mr. Ebrahimi SPH4U7 October 21st‚ 2012 Introduction Purpose: The purpose of this Physics Lab is to investigate what factors determine the amount of flexion of the cantilever. Hence‚ the objective is to establish a relationship between the length of a cantilever‚ which may give some insight into the physics of cantilevers. Hypothesis: If one increases the length of a cantilever‚ one would expect there to be an
