Data logging presentation
This document discusses using data logging in education for experiments. It notes advantages like more interesting experiments and accurate graphs, but also disadvantages like costs and computer literacy needs. The document outlines an experiment using a carbon dioxide sensor and data logger to monitor carbon dioxide levels during yeast fermentation with different glucose concentrations. It presents the results and leads a discussion on respiration rates and the role of paraffin oil and pressure valves. The conclusion states that data logging enhances learning and helps achieve learning outcomes.

- 2. Data logging • activityor experiment • collecting information and data • using electronic sensing instrumentation over specified time periods.
- 3. Data logging inEducation Advantages • School Experiment – Study become more interesting. – Will get accurate and better graph. Disadvantages • Computer literacy • Cost • Student skills
- 4. Engage, Empower andEnhance Model • Is one kind of teaching model • Set • Carried out • Questioning induction an experiment Engage Empower Enhance
- 5. Engage In this experiment,our problem statement is as stated as below: • What are the important ingredients do you need to make a bun? • What makes the dough expand and becomes bigger? • How to control the bun expand and becomes bigger in the shortest time?

- 7. • Carry outan experiment by using carbon dioxide sensor to detect the carbon dioxide release by yeast during fermentation. • Different concentration of glucose is used to observed the different in carbon dioxide concentration collected. • Data logger will collect time data and plot a graph

- 9. Carbon dioxide concentration/ppm Time/s
- 10. Discussion 1. Based onthe table, we can observe that the concentration of carbon dioxide increase from time to time, what leads to this increment? The changes of carbon dioxide level indicated that the fermentation of yeast in glucose has begun because more and more carbon dioxide is release.
- 11. 2. What isthe difference of above respiration with human respiration? The release of carbon dioxide indicates that this is an anaerobic respiration. On the other hand, human respiration is an aerobic respiration. The main differences in anaerobic and aerobic respiration is oxygen is absent in anaerobic respiration while oxygen is present in aerobic respiration. Oxidation of glucose is not complete in anaerobic respiration but it is complete in aerobic respiration.
- 12. 3. What arethe similarities of above respiration to human respiration? Both of the respirations are cellular respiration which involved the breakdown of glucose to release energy that stores in ATP molecules. 4. Why paraffin oil is added to cover the glucose solution? Paraffin oil is added to prevent air from dissolving in the glucose solution which might affect the result.
- 13. 5. What isthe function of pressure valve in the experiment? The valve is close to prevent air from atmosphere to enter the conical flask which we are monitoring the carbon dioxide release by fermentation of yeast. 6. Write an equation for the above experiment. C6H12O6 + 2 C3H5OH 2CO2 + 210 KJ Glucose Ethanol Carbon dioxide Energy
- 14. 7. Calculate therate of respiration of each concentration of glucose. Which concentration has the higher respiration rate? rate of respiration for 10% glucose = = 35.45 ppm/min rate of respiration for 5% glucose = = 114.22 ppm/min Based on the calculation, we can observe that 5% glucose has the higher rate of respiration. Calculation we obtained match the graph that we plotted before.
