Across
- 6. Used in the Enzyme CP to keep temperature constant for validity.
- 7. Used as a Control in the Respiration CP for comparison with living organisms.
- 8. In the Osmosis CP, this is the concentration of the sugar or salt solution.
- 9. Accuracy is defined as how close a measurement is to this.
- 10. This is high when all control variables are kept constant for a fair test.
- 12. In Microscopy, the specimen must be this so light can pass through for a fair test.
- 13. In the Osmosis CP, you repeat the test and calculate this to improve reliability.
- 14. Used in Microscopy to calibrate the graticule for better accuracy.
Down
- 1. Used in the Photosynthesis CP to measure volume more accurately than counting bubbles.
- 2. In the Photosynthesis CP, this is the number of bubbles produced per minute.
- 3. Results that don't fit the pattern; they are removed before calculating a mean.
- 4. Used in the Osmosis CP to dry the potato and ensure a true mass is recorded.
- 5. This is improved by having a large sample size of many quadrats in Fieldwork.
- 11. To help ensure validity in Respiration, the apparatus must be this so no gas leaks.
- 15. In Fieldwork, coordinates must be chosen this way to ensure an unbiased fair test.
