STEM Activities in Primary School: 5 Projects That Boost Creativity and Curiosity

Elementary school is the time when children are most receptive to learning, most curious, and most creative. During these years, hands-on, gamified, and discovery-focused learning methods help children gain not only knowledge but also self-confidence, creativity, and problem-solving skills .

Here are five easy-to-implement and highly effective STEM activities for elementary school students . These projects can be easily implemented both in the classroom and at home.

1. 🎈 Balloon Rocket Experiment

Learning Outcome: Understanding the relationship between force, motion and air pressure
Materials: Balloon, rope, straw, tape

How to do it?
Stretch a string across the room. Thread a straw through the string, and tape an inflated balloon to the straw. When you release the tip, it will propel forward like a rocket.

Why is it effective?
Through this experiment, children can directly observe the relationship between thrust, air pressure, and motion.

2. 🌈 Colored Milk Experiment

Learning Outcome: Observing surface tension and chemical reactions
Ingredients: Milk, food coloring, dish soap, cotton swab

How to do it?
Pour milk into a large bowl and add drops of food coloring to various spots. When you place a cotton swab dipped in detergent in the milk, you'll see the colors suddenly shift.

Why is it effective?
This simple experiment strengthens children's observation skills and curiosity . It also provides a concrete introduction to the concept of "surface tension," a common concept in chemistry.

3. ✈️ Air Resistance Test with Paper Airplanes

Learning Outcomes: Designing experiments, testing variables, and analyzing
Materials: Paper, tape measure, stopwatch

How to do it?
Make paper airplanes of various shapes and see which one flies the farthest. Try again, changing the wing shape or length.

Why is it effective?
In this activity, children learn the design process through trial and error and develop their analytical thinking skills by comparing the results they obtain .

4. 🏗️ Pasta Bridge

Learning Outcomes: Introduction to structural engineering, design and durability analysis
Materials: Spaghetti pasta, tape, ruler, weights (coins or small toys)

How to do it?
Build a bridge structure with spaghetti and test its strength by adding weights. Compare the durability of different designs.

Why is it effective?
Children develop their engineering skills and learn about cause and effect and the impact of design on function .

5. 💨 Making a Windmill with Natural Materials

Gain: Energy concept, transformation and environmental awareness
Materials: Straw, cardboard, plastic plate, paper clip, thumbtack, scissors

How to do it?
By designing a simple windmill, children can observe the driving force of the wind. They can test how well the windmill spins with different materials.

Why is it effective?
This activity provides an introduction to the concept of renewable energy and provides an interactive learning environment with nature.

Learning with Fun in STEM

What these events have in common:

• They are practical and experience-based ,
• Encouraging creativity and problem solving ,
• They are suitable for both individual and group work ,
• And most importantly: to make children feel that learning is a fun and meaningful process.
  
  

Through STEM activities, students develop a positive attitude not only toward the subject but also toward learning . They grow as curious, inquisitive, and questioning individuals.

Final Recommendations:

• During activities, encourage children to think by asking open-ended questions like, "Why do you think this happened? "
• Consider each attempt a "success." The important thing is the learning process rather than the correct answer .
  
  

Raise awareness with mini-chats of “what did we learn?” at the end of the activities .
