Exercise
Form 6: Chemical Energy Transformations
In this engaging exercise, students will explore the dynamic world of chemical energy transformations by conducting hands-on experiments to observe how energy is converted during chemical reactions, enhancing their understanding of concepts such as exothermic and endothermic processes. Students will then analyze their findings, fostering critical thinking and application of scientific principles in real-world contexts.
