Why Conduct Science Experiments at Home?
Conducting science experiments at home has several benefits:
1. Enhances Learning: Experiments provide hands-on experience, making concepts more relatable and easier to understand.
2. Fosters Creativity: Science encourages problem-solving and innovative thinking.
3. Sparks Curiosity: Engaging in experiments can fuel a lifelong interest in science.
4. Promotes Bonding: These activities can serve as great family bonding experiences.

Safety First
Before diving into the experiments, it’s crucial to keep safety in mind. Here are some general safety tips:
- Always wear appropriate protective gear (goggles, gloves, etc.) when necessary.
- Ensure good ventilation, especially when working with chemicals.
- Use materials that are safe and non-toxic.
- Supervise children closely during experiments.
