There is no one "right" age to start cultivating STEM skills, as individuals can begin to develop these skills at any age. However, research suggests that early exposure to STEM concepts can help to develop a strong foundation of skills and interest in these areas.

At home, parents can help to cultivate STEM skills in their children by:

1. Encouraging curiosity and exploration: Encourage children to ask questions and explore their environment. This can help to develop their critical thinking and problem-solving skills.

2. Providing hands-on experiences: Provide opportunities for children to experiment and build things using materials such as Lego blocks, play dough, and simple science experiments.

3. Encouraging reading and learning: Read books and watch videos with children that introduce STEM concepts and encourage them to learn about science and technology.

4. Encouraging outdoor exploration: Encourage children to spend time in nature and observe the world around them. This can help to develop their observation and analytical skills.

5. Enrolling children in STEM-related classes or camps: Look for classes or camps that offer hands-on experiences and introduce children to STEM concepts.

By providing children with opportunities to explore and learn about STEM concepts, parents can help to develop their interest and skills in these areas, regardless of their age.
