Global Warming is the increase of Earth's average surface temperature due to emission of greenhouse gases, such as carbon dioxide.

One of the causes to the global warming is combustion that release carbon dioxide and heat to the atmosphere.

Example of common combustion happen are deforestation (burning of wood) and fuel combustion in vehicle.

SCIENTIFIC CONCEPT

ENGAGE

Picture A Picture B

Picture A and B showed a lake condition after a few years. What happen to the

lake? Explain why this happen.

EMPOWERINGProcedure :

Discovery IC Data Logger

1. Design an experiment to investigate the effect of combustion to global warming.

2. Set up two beakers, one for treatment (place a candle inside) and another one as control.

3. Insert temperature sensor into both beakers.

4. Light a candle in the treatment beaker.

5. Record and compare the temperature in both beakers produce by the combustion for 90 seconds.

6. Repeat the step 3-5 for carbon dioxide sensor.

EMPOWERING Discussion:

1. From the graph, which beaker has higher temperature and carbon dioxide content?

2. Why is there a different between temperature and carbon dioxide recorded in both beakers during?

3. Which beakers mostly represent the earth atmosphere when global warming happens?

ENHANCE

Hybrid car is another environment-friendly way to reduce used of fuel in vehicles. Picture above shows an example of hybrid car used electric source to power it up. How the uses of these hybrid cars are helping to reduce global warming?

Temperature sensors are very sensitive toward small changes compare to regular thermometer.

Accurate readings even though the temperature change very fast.

Students can measure both temperature and carbon dioxide content reading without difficulties.

The graphs can be plotted easily and save time.

The software interface is user friendly and easy to handle by students.
