This activity demonstrates how electrolytes conduct electricity, helping students understand ionic solutions and their properties. By observing the conductivity of different solutions, students can connect the abstract concept of ions to real-world applications.
Using the principle of embodied cognition, children physically see and measure the effects of conductivity, making the concept of electrolytes more tangible. As they experiment with various household liquids, they engage in active learning, reinforcing their understanding through firsthand experience.
1. Gather 5 small cups and label them: water, saltwater, sugar water, lemon juice, vinegar. 2. In the first cup, mix 1 teaspoon of salt into 100 ml of water, stirring until dissolved. 3. In the second cup, mix 1 teaspoon of sugar into 100 ml of water, stirring until dissolved. 4. Take a small LED light bulb and connect its ends to the third cup with saltwater — note if it lights up. 5. Repeat step 4 for lemon juice and vinegar. 6. Record your observations: which liquids lit up the bulb and why?
