Fun Experiments with Exothermic and Endothermic Reactions
When learning about exothermic and endothermic reactions, students can try some cool experiments. Here are some easy and fun ideas to explore:
Burning Fuels: Light a small candle or use a match. Before you light it, check the temperature of the air around it. Once it’s lit, feel the air again. You’ll notice that the air is warmer, showing that this reaction gives off heat.
Mixing Calcium Chloride with Water: Take some calcium chloride (you can find this at a store) and mix it with water. When you do this, feel the container. It will feel warm. This means that heat is being released, which is an exothermic reaction.
Mixing Ammonium Nitrate with Water: Take some ammonium nitrate (this is also found at a store) and mix it with water. As you stir it, you will notice that the mixture feels cooler. This happens because it's absorbing heat, which shows that it's an endothermic reaction.
Baking Soda and Vinegar: Put some baking soda into a cup and add vinegar on top. You will see bubbles form and feel the cup get cooler. This reaction absorbs heat from its surroundings.
By doing these hands-on experiments, students can really see how energy changes happen in chemical reactions! Have fun exploring!
