At the moment there is a focus on the use of the Ministry’s equipment. To this end, cables are being created with which sensors can work with as many boards as possible, the STEM Extension with which we can program S1 & S2 with Mind+, Lego type building materials, Supporting materials with related lessons and books and suggestions. Seminars have been started to make use of the equipment available in schools.

The preparation of the Panhellenic Competition is in progress, for which the registration form for teams, information, the webinars for teachers’ preparation, etc. can be found here.

We can design our own knowledge and skills path.

Starting from what I am and where I want to go, we end up going through similar educational material, which is available in the [Repository] and in the [Repository structure] that is organised to facilitate this journey.

About Course

Activity Goals:

The purpose of these activities is to measure the speed of sound using Kundt’s tube. In order to calculate the speed of sound we first need to determine the wavelength λ of the sound pulses. Then, knowing the wavelength, we can calculate the speed of sound.

 

What Will You Learn?

  • Understanding the basic principles of wave propagation
  • understanding wave interference and standing waves
  • development of experimental skills - familiarization with the experimental dimension of physics and science
  • practical work, application of theory and theoretical calculations - better and more effective understanding of phenomena and theory
  • critical thinking and problem solving

Course Content

Resonance point detection and wavelength calculation
The aim of the activity is to create standing sound waves using the Kundt tube and determine the wavelength of the sound pulses.

  • Goal
  • Materials
  • Theory
  • Activity 1: Calculation of sound wavelength

Experimental calculation of the speed of sound
The aim is to determine the speed of sound experimentally and compare it with the theoretical value.
