The STEM approach in education emerged to raise individuals capable of solving the complex problems of the 21st-century knowledge society. We want our children and students to be able to solve problems and develop 21st-century skills — but how?

Implementing STEM education starting from the preschool years can be the first step. As a STEM lead teacher and a science teacher with a master’s degree in Educational Technology, I have drawn on my own knowledge and experience to create this series of STEM lesson plans.

We are at the first stage of the series: I have prepared five printable lesson plans designed specifically for preschool children (ages 4–6), ready to be implemented at school, in kindergarten, at activity centers, or even at home.

In each these PDF lesson plans you will find a list of materials and setup instructions, embedded resource links (real and clickable), optional activity extensions, and notes for educators.

2) 🌈 Rainbow Science: Colors in Action!

Dive into the magic of color with this engaging, hands-on color mixing STEM activity designed especially for young learners! This printable lesson plan guides students through scientific exploration and playful experimentation. 

You can download the lesson plan here.

For teachers, homeschooling parents, and STEM educators, these easy-to-implement, printable lesson plans require minimal preparation. Don’t forget to stay tuned for the elementary, middle, and high school versions of this series!

Redox Reaction in Action with a Salty Twist!

🔍 What Is a Redox Reaction?

Procedure:

1. Pour 25 grams of copper (II) sulfate and 100ml distilled water into a beaker to prepare a solution 

2. Add a pinch of table salt (NaCl). This provides chloride ions (Cl⁻) that act as a catalyst in the reaction.

3. Drop in a piece of aluminum foil or many pieces of small aluminum plates.

4. Observe the beaker: You’ll notice bubbling, heat release, and a reddish layer forming — that’s pure copper! (Almost)

Conclusion:
This experiment shows how reactivity and redox chemistry go hand in hand. With just a few household items and lab safety in mind, you can bring complex science concepts to life — right in your classroom or kitchen lab.

🧠 FAQs

Q: Can I reuse the copper formed?
A: You can collect it, but it’s not pure enough for practical reuse.

Q: What age group is this suitable for?
A: Ideal for middle school to high school (12+), with supervision.

If your school has a dark-colored wall, consider transforming it into a chalk-friendly art space. This area can become both a creative outlet and an educational tool—especially when decorated with science-themed illustrations. Drawings of lab equipment, cell structures, or physics formulas can serve as engaging visual aids that spark curiosity and reinforce learning.

One of the most popular pieces we created was a colorful sketch of the DNA double helix. It beautifully linked Chemistry and Biology by illustrating the molecule that carries the genetic instructions of life. The drawing captured the attention of both students and teachers, turning an ordinary wall into a conversation starter and a memorable learning moment.

As the challenges of environmental pollution continue to grow, there is an increasing focus on conserving raw materials and energy. Paper recycling offers a practical and impactful topic for science and STEM education, making it ideal for classroom discussions, student projects, and hands-on assignments.

Consider guiding your students through the steps of the engineering design process during the paper recycling activity. This approach can transform a simple task into a rich, hands-on STEM learning experience.

This activity is both easy to prepare and highly engaging for students. It serves as an effective way to introduce the concept of sound tones and is suitable for use during science lessons, extracurricular clubs, or independent project work. One of the strengths of this activity is its accessibility—the required materials are simple and can be readily found at home or in the classroom, making it an inclusive and adaptable option for diverse learning environments.

One of my professors during my master’s program once told us that every teacher should have a box filled with miscellaneous items—popsicle sticks, old tires, scrap paper, marbles, broken toys—anything that might seem useless at first glance. When approached with creativity and curiosity, these everyday objects can be transformed into meaningful teaching tools.

At the school where I worked, we didn’t have a budget for laboratory supplies. This challenge pushed me to think outside the box and look for alternative experiments using only the materials we had on hand. In doing so, I discovered a wide range of unconventional lab activities and creative classroom experiments, many of which I later shared with chemistry teachers across the country.

That experience taught me a powerful lesson: sometimes, limitations aren’t obstacles—they’re opportunities for innovation.

Lewis structures, a fundamental topic in high school chemistry, are also among the most challenging concepts for students to master.

A lack of understanding in this area can lead to difficulties in related topics such as chemical bonding, interactions between species, mixtures, solutions, and VSEPR theory. For this reason, a solid grasp of molecular structures is essential for long-term success in chemistry.

Let me tell you about a creative project one of my students did! I had asked him to complete a chemistry project. He’s a huge fan of Legos, though molecular structures weren’t exactly his strong suit—but he absolutely did an outstanding job.

One of the most important aspects of learning chemistry is becoming familiar with the formulas, systematic names, and common names of frequently used compounds. It is essential for students to learn these compounds, as they will not only encounter them repeatedly in high school chemistry classes but also find them relevant in real-life contexts.

Even unprepared students may feel encouraged to participate, and this can motivate them to come more prepared next time. Adding fun, movement-based challenges for incorrect answers (such as hopping on one foot, singing a song, doing push-ups) can increase both excitement and learning retention. These playful elements can make students eager to play the game again and again.

As all you know, one of the most popular games among young people when they gather is Taboo game.

 In this game, players attempt to get their teammates to guess a target word without using a list of related "forbidden" words. This engaging and interactive game can be easily adapted to the classroom setting and integrated into your lessons to support learning in a fun and meaningful way.
