In this project, you will conduct simple experiments to showcase endothermic and exothermic reactions. Learn how energy is absorbed or released during chemical reactions.
If an endothermic reaction is performed, then the temperature will decrease, while an exothermic reaction will increase the temperature.

Prepare the first beaker with baking soda and vinegar.
Mix and observe the temperature change with a thermometer.
Record the initial temperature and final temperature.
In the second beaker, mix calcium chloride with water.
Again, use the thermometer to measure the temperature change.
Record the results from both reactions.
Compare the temperature changes to classify the reactions.
Clean up the workspace following the experiments.
The baking soda and vinegar reaction should show a drop in temperature, indicating an endothermic reaction, while the calcium chloride in water will show a temperature increase, signifying an exothermic reaction.

Wear gloves and goggles when handling chemicals, and ensure proper ventilation.
Create a visual representation of energy changes during reactions.
Use graphs to illustrate temperature changes.
Explain real-life applications of these reactions.
Demonstrate the reactions during the presentation.
Endothermic reactions absorb energy, while exothermic reactions release energy.
Yes, various chemicals can demonstrate these reactions effectively.
Photosynthesis is an endothermic reaction, while combustion is an exothermic reaction.
