✅ – “The experiment was performed” instead of “We did the experiment.”
✅ – measurement precision, temperature fluctuation, contamination. biologjia 11

Tips for a High Grade in Biology 11 Reports ✅ Use scientific language – not “I saw it turned blue” but “The solution exhibited a blue-black color indicating the presence of starch.” ✅ – “The experiment was performed” instead of

Amylase is an enzyme that breaks down starch into maltose. Enzymes are proteins that function best at an optimal temperature. In humans, amylase works best at 37°C. This experiment tests the hypothesis: Increasing temperature up to 40°C will increase the rate of starch breakdown, but temperatures above 60°C will denature the enzyme, reducing activity.
✅ – “The temperature was measured” not “The temperature is measured.” 4. Common Grade 11 Biology Topics (choose one for your report) | Topic | Sample Research Question | |-------|--------------------------| | Enzymes | How does pH affect catalase activity? | | Cell transport | Does salt concentration affect potato mass (osmosis)? | | Photosynthesis | How does light color affect oxygen production in elodea? | | Cellular respiration | Does temperature affect yeast CO₂ production? | | Genetics | What is the chi-square ratio for a monohybrid cross? | | Evolution | How does natural selection affect allele frequency in a simulation? | | Biodiversity | How does species diversity differ between two local ecosystems? | If you tell me your specific lab or research topic , I can write a custom report outline or full example for you.
