10 Easy STEM Activities & Its Benefits for Children

10 Simple STEM Activities for Kids

With Science, Technology, Engineering, and Maths forming an integral part of today’s world, it is important to involve and engage kids in stem learning activities at a young age. It certainly fosters a love for science and also becomes a foundation for them to decide the career they want to pursue. Most activities take less than an hour and are ideal for keeping attention intact. Stem based activities are the buzz in education today, and kids love to find the answer to why, who, what, where through fun hands-on projects. Teachers equally love preparing their students for the future.

What Are STEM Activities?

STEM activities for preschoolers, stem activities for toddlers, are similar to science experiments. They involve not only science but also other key elements that garner a spirit of exploration and discovery. Children take away the lessons learned beyond school and home and apply them practically in their lives and careers. Any child interested and engaged in STEM topics will succeed in the future and have a hunger for knowledge that cannot be satiated.

Benefits of Stem Activities for Kids

There are several benefits to STEM activities for kids. Read below to learn more about the benefits you can get out of STEM activities:

  • STEM is not a study based on a topic but a holistic approach to teaching and learning subjects like Science, Technology, Engineering, and Math. At home, STEM activities use these subjects together to solve real-world problems.
  • All activities indoor and outdoor stem activities are inquiry-based and designed to answer a question.
  • STEM activities encourage children to view science and maths in a new light. It helps them understand how subjects like science help solve day-to-day problems and issues faced as adults.
  • STEM activities are a great way of encouraging and developing critical thinking and creative thinking in children. They provide a safe and fun way for kids to explore the concepts.
  • Even if a child does not choose science as a profession, the activities can help them in problem-solving, lateral thinking, applying logic, and fostering creativity in any aspect of life.

Importance of Hands-on STEM Activities for Your Children

Although STEM education is primarily based on the math and science curriculum, the hands-on approach is key in learning. By being actively involved and participating in every step of the activity, experiment, or project, kids take what they learn in a textbook and associate it with a real-life scenario. Kids are putting theories to the test, experiencing nature’s laws, making decisions, and observing effects. Subjects come alive, getting kids excited, and this is when real learning takes place. Kids learn the core science behind everything.

Why Do Children Require STEM & STEAM?

STEM is an acronym for Science, Technology, Engineering, and Math, and STEAM adds an A for Art. Both these approaches are integrated and encourage students to think broadly about real-world issues. Both involve an interdisciplinary approach to creating path-breaking innovations and revolutionizing several integral parts of our daily lives. As methodologies of teaching, children can ask questions, connect dots, solve problems and think creatively. The approaches can help kids make discoveries that could change the future. In fact, STEM jobs are an integral part of the world economy and will also be the source of several future livelihoods.

Interesting STEM Activities for Children

STEM Activities for Children

There are several STEM activities that can be done at home, school, and clubs to get kids involved and also excited.  Below is a compiled list of STEM activities that can be easily performed at home and make for an interesting learning session for you and your kids.

1. Cloud in a Jar

This science stem activity combines learning about the water cycle, condensation, and state of matter. It teaches children about how clouds are formed. The best thing about the activity is it can be adapted to young and older kids.

Category – Science Supplies 

  • A jar with a lid
  • About 1/3rd cup of hot water
  • Ice
  • Hairspray


  • Pour the hot water into the jar. Swirl it in the sides to warm the insides of the jar.
  • Now turn the lid upside down and place it on the top. Place several ice cubes onto the lid and let them rest on the jar for about 20-30 seconds.
  • Remove the lid and quickly spray a bit of hairspray into the jar. Replace the lid with the ice on top. Clouds will form, and kids will enjoy it.
  • As a good amount of condensation forms, the lids can be removed to see how the cloud “escapes into the air.”
  • You need to tell kids that warm water in the jar turns into a vapor that rises and comes in contact with the cool air (because of the ice). When the vapor condenses, it cools. A cloud can be formed only if the vapor can condense onto something, which in this case is the hairspray, and in nature, it is air pollution, dust, pollen, etc.

2. Straws and Tape

One of the best stem engineering activities, this teaches kids about coordination, building, and trying to make estimates. All with the help of simple straws, kids can create their own model that they think will help them to build a tower.

Category – Engineering Supplies

  • Drinking straws (regular or milkshake)
  • Tape
  • Ruler or yardstick


  • Get kids to use the straws and tape to build a tower. Tell them to connect their straws to build the tallest tower.
  • Younger children could be given a clue to build a base and work upwards.
  • Try to limit the number of straws to each child.
  • If you want a twist, you can ask them to use a pair of scissors to cut them and build them if they wish.
  • Now get them to measure their creations and compare.

3. Geometry With Marshmallows and Pretzels

One of the best math stem activities, this one can teach children about 2D shapes and their properties in the most practical way.

Category – Maths Supplies

  • Pretzels
  • Mini marshmallows
  • Card paper
  • Pen or marker


  • Draw a few shapes on the paper. Either write their name on the side or leave a blank for you or your child to write after you guess the name.
  • Break the pretzel sticks and get your child to place them on each side of the shape and connect the vertices with marshmallows.
  • Teach them about the name of the shapes and also explain the concept of sides and vertices with the help of pretzels and marshmallows.

4. Reflection Art

An incredible lesson on multiplication and also covering aspects of angles, symmetry, and geometry, this project is a jackpot for parents and teachers.

Category – Maths Supplies 

  • Mirrors
  • Card Paper
  • Pen markers


  • Draw a triangle and use pen markers to decorate the inside with geometrical patterns. If you have older kids, then you can get them to color them with geometric shapes like zig-zag lines, curves, shapes, etc.
  • Now give each child a mirror and ask them to place it on each of the sides of the triangle to see how the reflection appears.
  • As they see, the reflection explains the concept of symmetry.

5. Salt Pendulum Activity

There is something magical about how a pendulum works. The way it moves is dependent on factors like length, force, and weight. With just a few supplies, you can teach kids some important concepts of physics.

Category – Science Supplies
