In the experiment, we put the same amount of tap water in glasses and measured their initial temperature. After the measurement, we observed that the temperature of the water in the glasses increased, but the temperature of the water in the closed glass with the petri dish increased more than the temperature of the water in the other glass, when we covered the petri dish on one of the glasses and kept it under the sun for 1 hour and then measured it again.
When the experiment was completed, I explained why the plants should be kept in the greenhouse, the differences between the plants inside and outside the greenhouse. I asked the students to relate the temperature they will feel inside and outside the greenhouse and the experiment. We discussed with the students what different human activities could be that cause climate change.
We designed an experiment to understand the effect of carbondioxide gase to the atmosphere. I explainde the green house effect nd green house gases to the students before making the experiment. We spoke about the rise of carbondioxide gase amount in the air, which is also a green house gase. We discussed about the possible effects of rise of carbondioxide gase in the air. We concluded that rise of carbondioxide gase amount, which is especially produced by using fosil fuels, absorbs more sun light and thus makes the air much warmer than needed and eventually causes global warming.
We designed an experiment to help us understand that when the earth's atmosphere stores too much heat, glaciers will melt and therefore sea level will rise. After filling one of the 100 ml beakers with water to the brim, the students put it on the electric stove and observed that the water overflowed after about 10 minutes. We put 2 ice cubes in another beaker and filled the beaker to the brim with water. We observed that the heated water expands and slowly begins to overflow from the sides of the beaker, and in the other beaker, no water overflows even though the ice melts. Our teacher stated that the melting ice does not raise the water level in the bottle, because the ice is already floating in the water and occupies a space equal to its own volume. With this experiment, we made a connection between melting glaciers and rising sea levels. It has been announced that due to global warming, the ocean waters will warm up and rise and cover the coasts and small islets. She stated that the melting of the ice floating on the water does not change the water level, and that for the sea level to rise, the ice on land must melt and become water and mix with the ocean.
We conducted an experiment to observe carbon dioxide emissions and to understand the importance of balanced amounts of carbon dioxide for the natural cycle. In the experiment, we put a green leafy plant and lime water in the same jar and kept it in a dark environment for 1 day. When we checked the next day, we observed turbidity in the chalky water. I stated that plants breathe like other living things, take in oxygen and give off carbon dioxide. I stated that the carbon dioxide produced as a result of the respiration of the plant makes the calcareous water cloudy.
Based on the changes in their consciousness and behavior as a result of their work, our students who carried out the project organized activities to spread this effect to wider masses, to increase the social impact, and to make them aware of the problem and take action.
