Discover the Joy of Science: 16 Experiments Perfect for Elementary Students

When I am continuously going over worksheets or books with my elementary class, I notice my students’ long and bored faces, their eyes drifting away from the material. Because of this observation, I try to integrate at least one hands-on science experiment into my weekly schedule. This approach not only keeps the children entertained, engaged, and focused but also fuels their innate curiosity. The objective is to spice things up every once in a while to keep my classroom fun and the learning experience vibrant.

The Ultimate List of 16 Science Experiments for Elementary School

The future is dependent on humans who know how to use science to make sound decisions, innovate, and take part in cultural, political, and civic conversations. Understanding this, I felt a responsibility. With that being said, I wanted to help other teachers around the world learn how to introduce science in fun, practical, and interactive ways for their elementary-aged students. Therefore, I am sharing my ultimate list of 16 science experiments for elementary school in this article.

This is how experiments are held at Northridge Elementary School:

WOW! The 5th graders at Northridge Elementary School participated in our lesson NEWTON’S 2nd LAW OF MOTION. Their experiments helped them understand force, mass, and acceleration. https://t.co/IRMc0iv6RJ pic.twitter.com/a93gleNPnL — WPAFB EO Office (@wpafbeo) March 2, 2022

45 Science Activities For Elementary Students: Challenges And Experiments For Every Season

November 5, 2023 //  by  Christina Cunningham

Each season brings along new themes to explore in our elementary classrooms. In schools around the country, fall brings on studies of pumpkins and leaves, and winter sparks interest in snow and ice. Spring weather invites explorations of puddles and mud, and summer’s heat naturally causes students to ask, “How can we cool off?” Our elementary science experiments can help students explore their natural curiosities. Check out this list of science activities for ideas that span the entire school year!

1. Growing Pumpkin Seeds in a Pumpkin

This experiment begins with the sensory-rich experience of cutting and scooping out goopy pumpkin “guts.” Take this classic experiment a step further by replanting the seeds right inside the pumpkin! Students can track their growth in journals to practice the basic science skills of recording and representing data.

28. Elephant Toothpaste

Take ½ cup of hydrogen peroxide in a bottle and add 10 drops of food color to it. Now add 1 tablespoon of dish soap and mix the solution thoroughly. Set aside. Combine water and yeast in another glass and let it sit for 30 seconds. Now transfer the solution from the glass into the bottle and watch it explode.

29. Exploding Pumpkin

This is one of the easiest STEM activities you can do with your kids. Carve the inside of a small pumpkin and draw a horror face on the outside with a permanent marker. Take ¼ cup vinegar and add two drops of coloring agent to it. Mix and pour the liquid inside the pumpkin. Add 1 tablespoon of baking soda, stand back, and watch colored foam spray out of the pumpkin head.

33. Surface Tension Challenge

Take a coin and place it on any flat surface, like a table. Now gradually add drops of water to it using a syringe or dropper. You will soon notice a dome of water forming on top of the coin. This happens because of the surface tension of the water molecules.

34. Jelly Bean

This Jelly Bean science experiment is one of those STEM activities that most kids love. Just arrange the jelly beans in a circle on a plate. Now add warm water slowly so that you do not disturb the arrangement of the beans. As the water comes into contact with the beans it will dissolve the dyed sugar coat on the jelly beans- forming a beautiful rainbow.

35. Lava Lamp

Take a glass of water and add any dye to it. Now take a jar and add a cup of oil to it. Pour the colored water into the jar and add a fizzing tablet. The tablet will create carbon dioxide and form supercool bubbles which will move up and down in the jar.

36. Melting Ice And Salt

Take a glass of water and add ice cubes to it. Sprinkle in ½ teaspoon of salt and lay a string over the ice cubes. The salt will melt the water on the ice and as the water refreezes, the string will get trapped in the ice. So, when you pull out the string, the ice cubes will appear like a necklace on it.

37. Magic Milk

Pour some milk into a flat dish. Add a few drops of different dyes or colors to it. Now take a cotton swab covered in soap and dip it in the middle of the colors. The reaction between the fat and protein in the mixture will make the colors “dance”.

38. Rainbow Paper

Add a drop of clear nail polish to a bowl of water and dip black construction paper into it. Let it dry. Now take it out and tilt it at an angle under light to observe the rainbow patterns.

39. Spiral Paper

Take a sheet of paper and cut it into a spiral. Attach the paper to a string and hang it. Place a lamp below the spiral and watch the spiral go round and round. This happens because the air around the lamp gets heated. As hot air is less dense than cold air, it moves upwards, pushing the spiral and making it dance.

40. Tea Bag Ghost

You can make ghosts out of a tea bag. This cool experiment involves drawing a cute ghost on your tea bag, balancing it upright, and lighting the top; that’s it. Now watch the “ghost” fly away!

41. Magic Jumping Coin

Lower the temperature of a coin and glass bottle by placing them in cold water. Place the coin on top of the bottle and wrap your hands around it. The heat in your hand will warm up the glass bottle. It will then warm up the air molecules inside the bottle. This will cause the coin to jump up.

42. Unpoppable Balloon

One of the most fascinating and simple science activities is the unpoppable balloon experiment. All you need is an inflated balloon, a skewer, and dish soap. Dip the skewer into the dish soap and pierce the balloon carefully with it. The skewer will not pop the balloon.

43. Walking Water

Take 7 empty jars and add different colored water in all the odd-numbered ones. Keep the even-numbered jars empty. Roll a sheet of paper towel and bend it in the middle. Place one end in a water-filled glass and another in an empty one. Stare at the experimental setup and observe water “walking” from the water-filled cups to the empty ones. The mixing of the colors will also develop new hues in the even glasses.

44. Watch the Water Rise

Fix a lit candle on a plate. Pour water onto the plate. Add color to the water with a dye to improve visibility. Lower an upside-down glass over the candle to completely cover it. As the flame burns out, the water will rise in the glass.

45. Why Do Leaves Change Color?

In this simple experiment, kids will learn that there are many pigments present in leaves, but since chlorophyll is the most dominant, it imparts a green color. Take a leaf and break it into pieces. Place it in a jar containing alcohol. This will transfer all the pigments to the solution. Dip one edge of a coffee filter into the solution and observe the separation of colors as the liquid rises on the strip.

What is the Scientific Method for Kids?

The scientific method is a process or method of research. A problem is identified, information about the problem is gathered, a hypothesis or question is formulated from the information, and the hypothesis is tested with an experiment to prove or disprove its validity.

Sounds heavy… What in the world does that mean?!? It means you don’t need to try and solve the world’s biggest science questions! The scientific method is all about studying and learning things right around you.

As children develop practices that involve creating, gathering data evaluating, analyzing, and communicating, they can apply these critical thinking skills to any situation.

Note: The use of the best Science and Engineering Practices is also relevant to the topic of using the scientific method. Read more here and see if it fits your science planning needs.
