Mini Project

In the group consists of three member, my friends and I had given all our best effort to do the experiment using data logger. Before our group and other groups are given to proceed our experiment, we need to make our catchy title, engage, empower and enhance regarding to our chosen topics. Actually, my group was decided to do an experiment entitled ‘Acid-Base Titration’. However, there is misunderstanding regarding to this topic where we thought that this experiment cannot be conducted anymore because Dr.Sophia had already presentd it in lecture. Thus, we brainstormed to get the new topic and then we came out with ‘the effects of combustion’. Unfortunately, there is no oxygen sensor thus we have to change again our experiment. For the 2 hours, we do the experiment using DO to replace the oxygen sensor. But, it was waste. There is no data being collected and it just like a messy and useless work. Due to that problem, we do an appointment with Dr.Sophia and discuss about new experiment (after I spend my evening at library). Alhamdulillah, Dr.Sophia approved our new experiment and then we conducted the experiment of ‘The effects of light intensity to the rate of transpiration’. We used the temperature and humidity sensors to indicate the rate of transpiration at two different situations; in the presence and absence of light. For each situation, we spend for about 20 minutes. There are many advantages of using the data logger in conducting this experiment, where:

1) We do not need to measure the temperature and humidity manually

2) We can do other works during that period

3) The reading was taking for every second thus we can see even there is slightly changes in temperature and humidity

4) We do not need to draw the graph and collect data because the data logger already store the data automatically

5) Data logger helps in measuring and collecting data that cannot be measured manually, such as humidity

6) Less errors and bias during the measurement because the data itself measure the temperature and humidity automatically, thus provide more reliable result

7) Easy to set up the experiment using data logger where we just put the humidity and temperature sensors in the plastic that covering the plants, rather than put the thermometer in that plastic.
