STEM stands for Science, Technology, Engineering and Maths.

STEAM stands for Science, Technology, Engineering, Arts and Maths.

My passion is promoting positive forms of education that foster healthy child development. In pursuit of my mission, I’m constantly seeking out new, engaging activities and lessons that will ignite a passion for learning. My goal is to raise passionate life-long learners and help my readers do the same.

I’ve seen the positive influence STEM Activities can have on children’s learning and most importantly, their love of learning. Because at the end of the day if we raise children that don’t love to learn, then I really believe we have failed them as educators. STEM helps to foster a passion for learning, which is the greatest gift education can give all children.

Interested in learning more about STEM Activities and STEM education? I’ve compiled some of the most important information here to help you get started.

What is STEM?

The first thing we need to do is define STEM Activities. STEM is an acronym that stands for Science, Technology, Engineering and Math (referred to as pillars). It is an integrated teaching strategy that combines at least two of the pillars in the lessons and activities. You can learn more about STEM and the definitions here in: What is STEM? What is STEAM?

Why STEM Activities?

Children need to be engaged to learn. Because STEM is child centered using inquiry based principles, we allow children to take ownership of their learning. As their teachers we can support them in following their passions, we can get creative with our lessons, making them fun and interesting. With STEM we are teaching skills the way they will be used in the real world.

If an education produces a person who has lost their passion for learning, lost their curiosity, and removed their motivation to continue learning and growing, then it has failed. Education needs to support children in their learning journey, where ever that journey takes them in life. It should inspire and foster their passions to create successful, life-long learners.

STEM transforms school and education from a place to a state of mind. Teachers that employ STEM principles make real-life connections in their teachings. School becomes a state of mind rather than a place. School is not about going to a campus but about the experience of learning. With STEAM we are always growing, always experimenting, always thinking and always learning.

What are Inquiry Based Teaching Strategies?

In the previous section we mentioned inquiry based teaching principles and strategies. STEM activities engage students by promoting inquiry and questioning, then letting that form the framework for the lessons and learning.

From structured, to controlled, to guided, to free inquiry, students that are educated through the various levels of inquiry based learning develop strong skills in self motivation and problem solving. They also develop critical thinking skills, problem-solving skills and the confidence to advocate for their own learning and education. Essentially, they become their own best teacher. This is a fantastic skill for continued growth and success throughout a person’s life.

Learn more about inquiry based teaching strategies and how to apply them effectively in the article: Understanding and Applying 4 Inquiry Based Teaching Strategies

How to Adapt STEM Activities for All Students

One of the great things about STEM activities and lessons is how adaptable they are for the classroom or for a mom at home with multiple ages of kids. You can adjust almost any STEM activity to accommodate for different ages, abilities, interests and even group sizes. This is something I do regularly as I adjust lessons to accommodate my delayed learner and my gifted learner. STEM makes teaching those diverse needs, at the same time, easier. Learn key tips for adapting STEM activities.
