What experiments with FizziQ in High School? (ISCED3, K12 9th-12th)

Updated: Nov 22, 2021

While the final year program is often akin to a sprint race, the programs during years 9th, 10th and 11th leave more time for teachers for experimentation sequences. Using FizziQ, these important sequences will be more attractive for students, will allow group work, and will be simpler to conduct for teachers, allowing for a better understanding by students of inquiry based science education. To support you, we have put together some twenty protocols below that allow you to approach different parts of the science program in second and first.

Study of sound waves: Studying sound with FizziQ is made extremely simple and fast by the use of the sound library and the frequency generator which provide access to calibrated sounds that can be easily and directly analyzed by the student with sound portable. The practical study of sound waves becomes accessible and allows the teacher to experimentally illustrate many concepts that are sometimes difficult to teach. Below is a list of 10 protocols that you can use in the classroom or as homework:

  1. - Addition of noise to show the +3 db increase : https://en.fizziq.org/post/does-adding-two-sounds-really-increase-the-sound-level-by-3-decibels

  2. - Relation between distance to source and level : https://en.fizziq.org/team/chloé-at-the-concert

  3. - Frequency analysis with the study of tuning forks : https://en.fizziq.org/team/tuning-forks

  4. - Music scale : https://www.fizziq.org/team/la-gamme

  5. - Study of acoustic beats : https://en.fizziq.org/team/flume

  6. - Inharmonic Sounds : https://en.fizziq.org/team/the-sound-of-the-bell

  7. - Spectral analysis of vowels : https://en.fizziq.org/team/vowels

  8. - Noise cancellation : https://en.fizziq.org/team/noise-cancellation

  9. - Speed of sound calculation : https://en.fizziq.org/team/bang

  10. - Dopler effect : https://en.fizziq.org/team/doppler-effect

Study of movement: Smartphones include more sensors which are very useful for studying movement: the accelerometer and the gyroscope. These sensors produce data at high frequencies and are intuitive to students, and shed light on certain concepts that are difficult to study in the laboratory. Here is a list of 6 easy-to-perform movement experiments that use these sensors:

  1. - Compute the value of gravity g by measuring a free fall : https://en.fizziq.org/team/galileo

  2. - Centripetal acceleration and rotation rate : https://en.fizziq.org/team/astronauts-and-spinners

  3. - Build your own pedometer : https://en.fizziq.org/team/build-your-own-pedometer

  4. - Rectilinear movements with the study of a robot on Mars : https://en.fizziq.org/team/build-your-own-pedometer

  5. - Energy conservation with pendulum : https://www.fizziq.org/team/leibnitz

Kinematic study: Motion sensors such as the accelerometer or the gyroscope allow a microscopic analysis of the movements but do not allow more global analysis of the movement. It is for this reason that we have developed the kinematics module which allows video analysis of the position, speed or rotation of an object in space. Thanks to the power of laptops, students can very quickly analyze with their laptop sequences that they will record themselves or that they will find on the site www.fizziq.org or that will be sent to them by their teacher. Here are two examples of protocols that can be implemented:

  1. - Analysis of landing speed of a Space X rock : https://en.fizziq.org/team/space-x

  2. - Energy conservation of a pendulum : https://en.fizziq.org/team/huygens
