Science is all around us. What better way to explore the concepts of science than a hands-on experiment! Teachers might stray away from experiments because of the preparation and mess that can come with these types of activities, however, there are so many fun and easy experiments that take little preparation and bring a ton of fun! Your students will sharpen their skills as observers and scientists with these engaging experiments!

Engaging primary school students with fun and easy science experiments will not only spark their interest and curiosity, but can make science concepts tangible and help with overall understanding. 

According to Pedagogy in Action, “experiments can be used to introduce new ideas or to clarify puzzling aspects of topics with which students typically struggle. If the result of an experiment is surprising yet convincing, students are in position to build ownership of the new idea and use it to scaffold learning.”

Science study is typically split into four domains: Physical Sciences, Biological Sciences, Earth and Space Sciences, and Engineering. Below you’ll find fun, easy, and engaging science experiments for each of these domains! 

4 Science experiments for primary school students

Each activity will take minimal time, effort, and resources to implement in the primary school classroom. They are the perfect way to introduce a new unit, review concepts in a hands-on format, or excite students to explore the world as scientists! 

1) Physical science balloons in motion

In Physical Science, primary school students study the properties and changes of matter, forms of energy, and forces of motion. Looking closely at Newton’s Laws of Motion will help students begin to unpack the forces that they see and use in their everyday lives!

This science experiment demonstrates Newton’s Third Law of Motion: for every action, there is an equal and opposite reaction. Students will use air in a balloon to conduct this science experiment! 

You’ll need

1. Balloon
2. Straw
3. String
4. Tape
5. Scissors

Procedure 

1. Thread the straw on a large piece of string. 
2. Cut the string and tie it to two objects in the classroom, such as two chairs.
3. Inflate the balloon and hold the end so no air escapes.
4. Attach the balloon using tape to the straw with the opening uncovered.
5. Release the end of the balloon and observe the air moving the balloon in one direction along the string. 

After conducting this experiment, complete the following formative assessment with your students. 

Formative Assessment Questions

1. Which of Newton’s Laws is shown in this experiment?
   • Newton’s Third Law
   • Newton’s First Law
   • Newton’s Second Law
2. How does the balloon move along the string in this experiment?
   • As air is released from the balloon it creates a force in one direction, so the balloon moves in the opposite direction. 
3. True or False: Would the balloon move differently if there was a weight tied to one end of the string?
   • True

2) Biological science beaks are unique

Primary students will study a variety of topics in Biological Sciences, including habitats, adaptations and life cycles. In this experiment, students will enjoy observing and making conclusions about an organism’s reaction to their environment. 

Teachers can discuss a variety of topics with students while using this experiment. Ecosystems, animal adaptations, and the evolution of species are all relevant conversations that can stem from this project.

You’ll need

1. 5 tools to represent beaks (tweezers, chopsticks, eyedropper, spatula, bulldog clip) 
2. 5 “food items” (Ex. uncooked rice, candies, liquid, seeds, pasta)
3. 5 containers or paper cups/bowls

Procedure 

1. Break students into smaller groups and give each group a “beak” to use during this experiment. 
2. Give each group some of the food items. 
3. Students will use their “beak” to pick up each food item and record their observations. 
4. Discuss findings of each group. 

After conducting this experiment, complete the following reflection activities with your class!

Formative Assessment

1. True or False: Different beaks can pick up different types of food?
   • True
2. Why are animal adaptations important?
   • Without animals adapting to their environment they would not survive. For example, if a bird living in a dry environment did not have the beak to pick up its food, it could not live.
3. True or False: All birds eat and can eat the same type of food.
   • False

3) Earth science explosive volcanoes

In this experiment, students will have fun exploring volcanoes! Students will create their own volcanic eruption and observe how it changes and affects the Earth’s surface. 

This experiment is best suited for outside, as it can get quite messy. Make sure there is a space you are comfortable with before bringing this project to your students. 

Volcanic eruptions are an exciting and engaging topic for primary school students. Not only can they lead to discussions on natural disasters and landforms, but also the connection to chemical reactions and how they occur!

You’ll need

1. Plastic bottle
2. Vinegar
3. Baking soda
4. Dish soap
5. Food dye (optional)

Procedure

1. Place the plastic bottle on a flat space surface 
2. Fill the bottle halfway with vinegar
3. Add a few tablespoons of dish soap 
4. (Optional) Add a few drops of food colouring
5. Add about a tablespoon of baking soda to the bottle and step back

Formative Assessment

1. What caused the eruption of the volcano? How do you know?
   • The mixing of the chemicals caused the eruption.
2. A volcano is essentially an eruption of the earth’s _______________.
   • Surface
3. In this experiment, what does the vinegar, soap, baking soda mixture represent?
   • Lava

In Volcanoes, students will learn background information as to what actually causes a volcano to erupt! 

4) Engineering marshmallow catapult

Students are challenged in this experiment with an engineering task to create a catapult that can launch a marshmallow! This requires teamwork and good planning and preparation in order to trial and error different catapults. 

This experiment might take two lessons. Students can begin by drawing a diagram of their catapult and thinking about the tools they might need in order to effectively launch the marshmallow. Then, students can spend time creating their catapult with observation and testing. 

You’ll need

1. Marshmallows
2. Plastic Spoon
3. Paddle pop Sticks
4. Rubber bands
5. Masking Tape

Procedure

1. Use paddle pop sticks to create the base of the catapult and secure it with rubber bands. 
2. Use tape to attach the spoon to one end of the base of the catapult. 
3. Place a marshmallow on the spoon and launch it. 
4. Adjust the catapult as needed for best results. 

Formative Assessment 

1. What causes the marshmallow to launch?
   • The force of the catapult being pulled down.
2. What is the criteria for success in this experiment?
   • Launching the marshmallow
3. What is the controlled variable of this experiment?
   • The spoon and marshmallow
