STEM challenges are a fantastic way for children to learn in a hands-on, interactive way, hopefully sparking a curiosity and passion for science and technology.
My ever growing collection of STEM challenges are free to download and cover a wide range of topics from creating a bed for the Princess and the Pea to designing a machine to clean rubbish from the ocean.
Most of the challenges use inexpensive and simple materials you probably already have at home, so you can get started straight away.
Benefits of STEM Challenges
- Provide opportunity for hands-on learning.
- Mirror real world problems, allowing children to understand how science concepts apply to everyday life.
- Help develop analytical skills and critical thinking, providing the opportunity to test solutions and evaluate results.
- Open-ended STEM challenges encourage creativity and innovative thinking, often through trial and error.
- Provide an opportunity to work as part of a team, encouraging collaboration, and effective communication skills.
