🌳 Year 11 Geography Trip – Karura Forest
14th February 2026
A Day of Fieldwork at Karura Forest – A Year 11 Experience
As a Year 11 student, our trip to Karura Forest was one of the most engaging and informative Geography experiences I have had so far. Instead of learning about rivers from a textbook, we were able to step into the environment ourselves and collect real data. Throughout the day, we visited three different river sites where we measured river depth, width, speed, wetted perimeter, bed load, and the pH of the water.
At the first site, the river was shallow and moderately flowing, with many rocks and pebbles scattered across the channel. The uneven bed influenced the water’s movement, creating ripples and slight changes in speed. The pH measured 7.5, slightly alkaline and close to neutral, showing fairly balanced conditions. It was a strong starting point to observe how bed load and channel shape affect velocity and energy.
The second site brought a dramatic change. The river was much deeper and extremely fast flowing, with dips in areas where heavy boulders were absent and fewer rocks overall. Measuring the speed required careful coordination with the flow meter and stopwatch. The pH was around 10, strongly alkaline, which surprised us and encouraged deeper thinking about environmental factors.
At the third site, the river was extremely muddy and moderately deep, making sediment more visible but harder to measure accurately. The contrast between the sites clearly showed how rivers change over short distances. The refreshing walk back to the bus gave us time to reflect on our findings, and working in groups strengthened our teamwork, making the experience both exciting and informative.
Beyond the data itself, the experience helped us build essential skills. Working in groups strengthened our teamwork and communication, while handling equipment independently increased our confidence and responsibility, as the trip helped us build on and apply our knowledge on rivers. The refreshing walk back to the bus gave us time to reflect on our findings and patterns. Most importantly, this trip directly supports our Paper 4 Geography exam, as we now fully understand how to collect, present, analyse, and evaluate fieldwork data from real experience rather than just theory
Overall, my experience was positive and this trip allowed me to gain more knowledge on the topic of rivers.
