So far students have been able to investigate:
- Carbon dioxide levels with reference to climate change
- Accelerated motion
- Temperature change in different substances
The Grade 11 physics classes used the Picket Fence (pictured at left) and photogates to measure acceleration due to gravity. Many of the students were really impressed by the simplicity and accuracy of the equipment.
Small groups worked together to collect several sets of data, which were then downloaded to each student’s computer for analysis. Once uploaded, the data will automatically save on each student’s computer, giving them the opportunity to work through the analysis at their own pace.
The graphs that were generated were easy to understand and manipulate, giving more time for students to analyze and discuss their results.
This lab activity allows for the students to investigate why and how objects accelerate towards the earth due to gravity, and gives many opportunities for related extension activities.
