Understanding energy changes in exothermic and endothermic reactions can be tricky. But we can make it easier to grasp with some cool experiments! Here are a couple of ideas:

1. Exothermic Reaction: Burning Magnesium

   • You need to handle magnesium and oxygen with care.
   • It can cause burns, so it's important to wear protective gear.

2. Endothermic Reaction: Dissolving Ammonium Nitrate

   • Measuring the temperature could be a bit difficult.
   • Wrapping the container with insulation can help you get better measurements.

To make sure your results are accurate, using the right thermometers and repeating the experiments a few times is really important.
