High School (14-18 years)
Students learn to work with the gas chromatographer (BT45i) while doing this activity. They use hydrogen gas obtained from the Hofmann apparatus. This activity is easy and fast and helps students to master the BT45i so they can use the gas chromatographer for other more challenging activities. Hydrogen gas gives an easy to analyse chromatogram.
Activity Gas chromatography
In this activity the blood pressure is derived from measurements with the blood pressure sensor. In the analysis the oscillometric method is used.
Activity Blood pressure
In this activity students record temperature during a cooling process of hot water and check the validity of Newton's law of cooling for the collected data
Activity Newton’s law of cooling
In this activity students measure on the video clip and graph the movement of a trampoline jumper. Students create the velocity and acceleration versus time graphs and analyse both graphs. They investigate the relationship investigate the relationship between the position, the velocity and the acceleration of the jumper.
