    Update: This article was last updated by Moonpreneur on 25th May 2023 to reflect the accuracy and up-to-date information on the page.

    Inventions! When we think of invention, the likes of Edison or Graham Bell crosses our mind. But, an invention is simply the product of our creative mind, and it can begin with simple do-it-yourself (DIY) activities. Therefore, we must create opportunities for them to express their creativity. With the right guidance, every child has the potential to become a budding innovator.  

    Moonpreneur brings 10 exciting invention ideas that your child can explore for school projects. These projects not only foster skill development but also encourage students to discover their strengths. The ideas are divided into four categories.
