1. Data logging involves measuring and recording physical or electrical parameters like temperature, strain, voltage, current, pressure, force, and acceleration over time. 2. A data logging system contains three main components: a sensor, data logger hardware, and a computer. 3. Using data loggers in teaching and learning can motivate students and teachers, increase interest in science subjects, and produce graphs and tables automatically, avoiding human errors.

2. Introduction
• Data logging is use in measuring and recording
of physical or electrical parameters over a
period of time.
• common parameter of measurement that were
used for data logging system.
– Temperature, strain, voltage, current, pressure,
force, and acceleration.

3. Cont…
• Contain three main components that are
sensor, data logger hardware and computer.

4. APPLICATION OF DATA LOGGING IN
TEACHING AND LEARNING
• can motivate and increase interest of pupils
and teachers to learn and teach sciences
• Advantages of using data logger over
recording data manually.
– measurements are always taken at the right time.
– Humans can make parallax errors
– graphs and tables are produced automatically by
the data logging software

5. Melting & Boiling point
A) ENGAGING PHASE
• The 2 pictures are displayed
• Asking question to relate the picture displayed
with the topic learned.

6. B) EMPOWER PHASE
Title : melting and boiling point of a substance
Objectives:
In this experiment, you will
• use a computer to measure temperature
• analyze graphs of your data to determine the
freezing and melting temperatures of water
• determine the relationship between the freezing
and melting temperatures of water

7. Materials Used:
– Ice cube, 250 mL beaker, bunsen burner, temperature
probe (sensor), interface box and computer
Procedure:
1. Place the ice in the 250 mL beaker
2. Place the temperature sensor in the ice.
3. Connect the sensor to an interface box linked to
the computer as shown in figure 3.

8. Figure 3
4. Click the start button. Observe any transition
process and the temperature they start to change.
5. When all the ice melts, continue the experiment by
placing Bunsen burner below the beaker for heating
the water as in figure 4

9. Figure 4
6. Click the Statistics button. The temperature value for
the selected data is listed in the statistics box on the
graph.

11. Based on the data obtained from data logger, students
are ask to fulfill the following table and identify the
phase of experiment for every 30 seconds. They also
must discuss why there has a flat line in the graph. The
results are in table below:
Time taken , seconds Temperature, (oC) Phase
30 0 Solid-liquid
60 0 Solid-liquid
90 0 Solid-liquid
120 0 Solid-liquid
150 30 Liquid
180 50 Liquid
210 70 Liquid

12. C. ENHANCE
• Students are group into 5 and every group is
given a same case study to be discuss in a group.
• The case study is ‘what happen to the heating
curve if salt is added into the water’. Discuss .
D. CLOSURE
• Students are asking to flashback what they had
done in the class.

13. CONCLUSION
Data loggers help in better understanding of
scientific experimentation. Other than that, the
used of data logger for determination the state of
matter can be more accurate.
