It then details the students' experiment measuring oxygen levels during photosynthesis under varying light intensities. Tables and graphs show the results of the experiment. The conclusion discusses how data loggers can benefit the learning process by providing accurate results and automatic data analysis.
1. The document describes an experiment using a data logger to study transpiration in plants. Students recorded humidity levels with a sensor inside a plastic bag wrapped around a plant branch under two conditions: with light and without light in a cupboard.
2. Results showed that humidity levels inside the bag rose more quickly when the plant was in the light, indicating greater water loss from transpiration.
3. A data logger allows automatic, accurate measurements over time without human error. Graphs and tables of results can then be analyzed to understand phenomena like transpiration.
Data loggers are instruments that can record measurements from sensors over time. This document discusses using a data logger to study transpiration in plants. The experiment aims to determine if plants lose more water with or without light. Sensors are placed in plastic bags wrapped around plant branches in both light and no light conditions. The data logger records humidity levels, which are plotted on graphs. Results show that plants transpire more and humidity inside bags decreases more rapidly when exposed to light compared to no light conditions. This is because transpiration cools plants, and transpiration occurs more when plants are heated by sunlight.

This document discusses using a data logger to analyze the effect of particle size on reaction rate. An experiment was conducted using Alka-Seltzer tablets of different sizes added to water, while measuring the carbon dioxide produced over time. The results showed that smaller tablet particles produced carbon dioxide at a faster rate, as smaller particles have a larger total surface area, allowing for more frequent collisions and a faster reaction. In conclusion, data logging provides an effective way to automatically collect and analyze experimental data on factors that influence reaction rates.

1. The document summarizes how photosynthesis works through light-dependent and light-independent reactions. It describes the process of capturing energy from sunlight to make ATP and NADPH, and then using these products to fix carbon dioxide and produce sugars.
2. Photosynthesis takes place in chloroplasts in plant cells, which contain thylakoid membranes where the light-dependent reactions occur. These reactions use light energy to convert water to oxygen and produce ATP and NADPH.
3. The light-independent reactions then use ATP and NADPH to fix carbon dioxide and produce glucose through the Calvin cycle. This provides the sugars and starches that plants need for growth and energy storage.
This document discusses the process of photosynthesis. It occurs in plants, algae, and some bacteria to convert solar energy into chemical energy stored as glucose or other organic compounds. Photosynthesis provides the foundation for most food webs as it produces oxygen and energy in the form of glucose, which can then be converted to ATP through cellular respiration to power biological processes in other organisms. The rate of photosynthesis is influenced by several factors like the amount of chlorophyll and light intensity.

Introduction
Energy is required by living organisms for
movement, transport, and growth. Nothing
happens without energy! The Sun is the
ultimate source of virtually all energy on the
planet Earth. Solar energy is captured by
plants through the process of photosynthesis.
The glucose molecules holding this energy are
broken down by metabolic processes, creating
usable energy for living systems.
Cellular respiration is a series of reactions in
which glucose molecules are broken down,
releasing stored chemical bond energy
(Figure 6.1). The released energy is used to
make the energy rich molecule ATP
(adenosine triphosphate). Carbon dioxide is
released as a by-product of the breakdown of
glucose. It is a crucial by-product from the
perspective of plants, because they need CO2
to perform photosynthesis.
Glycolysis is the first step in cellular
respiration, and it results in the net production
of two ATP molecules. In glycolysis, the 6-
carbon glucose molecules are “split” into two,
3-carbon pyruvate (pyruvic acid) molecules.
LAB TOPIC 6: RESPIRATION
Pyruvate has two potential routes – aerobic
respiration or anaerobic respiration [as either
lactate fermentation or alcohol fermentation]
(Figure 6.1).

In laboratory today, you will be examining
respiration in organisms that use aerobic
respiration, which makes use of oxygen. In
this pathway, pyruvate is broken down
completely, and h igh-energy electrons are
stripped away and passed through a series of
electron carriers. Energy is released at each
transfer, and is used to make a net 34 ATP
molecules. Oxygen is the final electron
acceptor in the electron transport system,
hence the name aerobic cellular respiration. In
lecture you will compare this process to
anaerobic respiration, which occurs in the
absence of oxygen or under low oxygen
conditions. The equation below summarizes
the process of aerobic respiration:

INTRODUCTION
Data logger is an instrument that collect measurements of temperature, light intensity,
relative humidity, voltage, pressure, on/off and open/closed state changes. Data-logging
implies data collection with storage for later data processing. A data-logging system has three
main components: an interface to link to a computer, sensors and software. While planning to
purchase a data-logging system, the following points need to be considered as well: purchasing
strategy, organising resources, features and prices. Data-logging implies data collection with
storage for later data processing. A data-logging system has three main components: an
interface to link to a computer, sensors and software. While planning to purchase a data-logging
system, the following points need to be considered as well: purchasing strategy, organising
resources, features and prices.
The data logger is first connected to a personal computer. Specific software is then used
to select logging parameters and initiate the logger. The logger records each measurement and
stores it in memory along with the time and date. The logger is then reconnected to the personal
computer and the software is used again to readout the data and view the measurements as a
graph or table showing the profile over time. The data collected can be exported to a
spreadsheet for further manipulation.
There are a few types of data logger and the differences between various data loggers
are based on how they that data is recorded and stored. The basic difference between the two
data logger types is that one type allows the data to be stored in a memory, to be retrieved at a
later time, while the other type automatically records the data on paper, for immediate viewing
and analysis. Many data loggers combine these two functions, usually unequally, with the
emphasis on either the ability to transfer the data or to provide a printout of it.

ADVANTAGES AND DISADVANTAGES OF DATA LOGGER
Advantages
1. The data logging can work as per its design. Some equipments log data 24 hours a day
and 365 days of year while some logs data only during its predefined period.
2. Measurements are always taken at the right time. Unlike a human the computer will not
forget to take a reading or take a reading too late or too early.
3. It can be used in remote or dangerous situations. Data logging devices can be sent to
places that humans cannot easily get to. For example to the planet Mars, into the bottom
of a volcano, or onto a roof of a tall building to get to a weather station.
4. It is very accurate as likelihood of human error is not there.
5. Graphs and tables of results can be produced automatically by the data logging
software.
Disadvantages
1. It requires initial investment cost to start using the data logging service. Moreover the
equipment is expensive for small tasks.
2. Often all the features are not available in data logger equipment and hence requires
modification in the software or application.
3. If data logging equipment malfunctions, some data could be lost or will not be
recorded.
4. Certain data logging equipment can take readings only during interval configured at
the start.
5. Basic training is needed to use the equipment.

EXAMPLE OF DATA LOGGER: PHOTOSYNTHESIS
Engage
1. Why we said plant needs light for photosynthesis?
Photosynthesis occurs when green plants use the energy of light to convert carbon
dioxide (CO2) and water (H2O) into carbohydrates.
2. What is the relationship between the oxygen produced and the reaction of
photosynthesis?
Photosynthesis is the process by which plants and some bacteria and protists
synthesize sugar molecules from carbon dioxide, water, and sunlight. Photosynthesis
can be divided into two stages which are the light dependent reaction and the light
independent reactions. During the light reactions, an electron is stripped from a water
molecule freeing the oxygen and hydrogen atoms. The free oxygen atom combines
with another free oxygen atom to produce oxygen gas which is then released.
3. How the light affect the photosynthesis?
Without enough light, a plant cannot photosynthesise very quickly, even if there is
plenty of water and carbon dioxide. Increasing the light intensity will boost the speed
of photosynthesis.

Discussion
1. What does the graph tell you about the changes in dissolved oxygen level during
photosynthesis?
Based on the graph, dissolve oxygen fluctuating according to light intensity.
2. Why does the oxygen level change?
During the day, photosynthesis occur, the food are converted into energy, plant use
carbon dioxide and released oxygen. When the light intensity is high, the plant produce
more oxygen. Thus, the oxygen level change according to the light intensity.
3. How do the graph change with respect to each other?
As the light intensity increase, the concentration of dissolve oxygen increase.
4. What is the end product of this experiment? State the equation of photosynthesis.
End product of this experiment is glucose and water. Photosynthesis is the conversion
of carbon dioxide and water to synthesize nutrition (energy) in the presence of sunlight,
whilst releasing oxygen as a byproduct.
The equation is given as below:

How photosynthesis can provide energy to humankind?
If we are discussingaboutphotosynthesis,the firstthingthatacrossourmindwouldbe a tree
or a plant because thisprocessusuallyoccur in plant.But how isit happened?We consume plantas
our food but how energy can be absorbed into our body?
Plants that stored solar energy in their bodies millions of years ago by means of
photosynthesis,and animalsthat ate these plants, gave rise to the petroleum or energy with which
we are familiar, underground and under high pressure, after a period of millions of years. Coal and
natural gas came into being in the same way. In short, the solar energy stored in plants thanks to
photosynthesis was placed at our disposal after millions of years had passed.
Similarly, the energy you obtain from the food you eat is simply the solar energy stored by
plants.The energyyouobtainfrom animal foodstuffsisalsothe energythose animalsobtainedfrom
plants. The source of energy is always the Sun, and the system that makes this energy useable by
humanbeingsisalwaysphotosynthesis.Youcannotacquire the energyyoupossessbymeansof any
system other than photosynthesis.
Extension
What living organisms are responsible for photosynthesis? What cell organelle is responsible
for the absorption of light in the photosynthesis process in plants and algae?
There are many organisms (including all animals) that do not use photosynthesis. There are
also autotrophic organisms that do not perform photosynthesis but which do perform
chemosynthesis. Plants, algae and cyanobacteria are photosynthetic organisms. In plants and
algae, light is absorbed by chlorophyll, a molecule present in cytoplasmic organelles called
chloroplasts.

CONCLUSION
Data logger is another way that can be use in our education system. This is because, by
using this kind of method, we can improve our teaching and learning method. Data logger is
important because it can provide students with critical thinking while they were answering the
question while doing and can provide them a clear instruction on how to do an experiment.
Students also can get involved in class activity if the teacher introduced data logger learning
program. The result provide by data logger also trusted as it gives us an accurate result. It is
also can produced graphs and tables automatically by the data logging software. So it is clear
that data logger can give benefits to the learners especially student during learning process.
