Escola Profissional de Almada

Description

Vocational Educational Training School in Almada, south of Lisbon (about 350 students. Students’ age: 14-23)

Goals

To determine air density using school stairs and a pressure sensor.

To discover and study the variation of atmospheric pressure with the variation of altitude, on a field trip.

Methods

Students use the pressure sensor from a smartphone (or an Arduino with a pressure sensor), a measure tape and the schools’ stairs to study the variation of pressure with altitude and to determine the density of air. After that, students are taken to the field and determine the height hill or building.

Materials

Smartphones, tablets, computers, interactive whiteboard, internet and inquiry learning scenarios.

Assessment

Students must explore the provided inquiry learning scenarios and make presentations.

ICT

Students can use ICT to predict and record their findings. Students use their smartphones or Arduinos to measure pressure and height.

eTwinning

Mobility

Students work in groups. They can use the school stairs to discover the variation of pressure with height. In the second part of the activity, students go up a street to determine its height using their findings from the first part of the activity.
