The Internet is full of interesting science projects for kids to explore and learn. But how do they get started in this vast pool of knowledge?
Here, we carefully curate the most engaging experiments for primary school kids to explore, using material easily found at home. They are then directed to videos that best explain the science behind the experiments, and the coolest projects for them to make and apply the learning.
Through this learning path, we hope to reignite children's inborn passion to question the world around us and get them started on a path of lifelong learning.

Episode A: Which one falls first - ball or feather?
Episode A: Which one falls first - ball or feather?
Gravity and drag: Objects of different shape and weight fall down at the same speed due to the force of gravity. However, in the presence of air, there is another force called drag that slows down the fall.
Experiment to try
Make a helicopter to see how drag slows down falling object.
How does it work
See which one fall faster - feather or bowling ball - in a giant vacuum chamber!
Fun project to make
What happens when you change the parachute size and the load's weight? Can parachute work on the moon?
Episode B: Do rubber bands have energy?
Episode B: Do rubber bands have energy?
Potential energy: Material that is compressed (e.g., spring) or stretched (e.g., rubber band) can store energy. This energy, called potential energy, can be converted to another form such as kinetic energy.
Experiment to try
See how potential energy stored in the rubber band makes the frog jump.
How does it work
Converting potential to kinetic energy in the International Space Station.
Fun project to make
Make a launcher. Can you launch the parachute you made earlier? How do you make it go higher?
Episode C: Can I hear someone talking on the moon?
Episode C: Can I hear someone talking on the moon?
Sound vibration: Sound is created through vibration. The vibration travels from one point to another through medium such as string or air.
Experiment to try
Make a funny sound with a cup and a piece of string.
How does it work
What makes sound? How does it travel? Can you listen to your radio through the string phone.
Fun project to make
Make your very own stethoscope. Can you hear your heart beat? What else can you use it for?
Episode D: Can aeroplanes fly without wings?
Episode D: Can aeroplanes fly without wings?
Bernoulli's principle: When air flows through area A faster than through area B, low pressure will be created in area A. This phenomenon is the reason why water in a spray bottle is pushed up and air lifts the airplane wings.
Experiment to try
Why does the water rise up when you blow into the straw?
How does it work
Learn how low pressure makes the balloon and the tent behave strangely.
Fun project to make
What makes the water rise up, also makes the plane fly. Search YouTube for cool paper planes to make.
Episode E: Can you move an object without touching it?
Episode E: Can you move an object without touching it?
Static electricity: When an object is rubbed, it becomes either negatively charged or positively charged. Objects of the same polarity repel each other, while objects of different polarities attract each other.
Experiment to try
Isn't it magic when you can move an object without touching it?
How does it work
See how electron moving from one object to another causes lightning!
Fun project to make
Perform awesome tricks with static electricity! How do you know whether an object is negatively or positively charged?
Episode F: What happens to a skater when she throws a ball forward?
Episode F: What happens to a skater when she throws a ball forward?
Newton 3rd Law: For every action, there is an equal and opposite reaction.
Experiment to try
Blow hard and make the straw spin!
How does it work
See Newton 3rd Law in action, making a man fly!
Fun project to make
Make your own jet engine using a balloon. What can you use this engine for?
Episode G: Why does a tightrope walker hold a pole?
Episode G: Why does a tightrope walker hold a pole?
Centre of Gravity: All objects behave as though their weight is concentrated at a point called their center of gravity (CG). The lower the CG, the more stable the objects are.
Experiment to try
What other objects can you balance?
How does it work
Learn how to make an object stable by moving its centre of gravity.
Fun project to make
Does the object roll down, or does it roll up?
Episode H: Can you power a boat with soap?
Episode H: Can you power a boat with soap?
Surface tension: Surface tension is like a layer of stretched membrane on the surface of water due to water molecules sticking together. Soap can lower the surface tension.
Experiment to try
Make different boats, and race them!
How does it work
Force acts from lower surface tension to higher surface tension, that’s why the boat moves forward!
Fun project to make
Perform awesome tricks with surface tension! So what actually causes surface tension?
Episode I: Can you bend light?
Episode I: Can you bend light?
Refraction: Wave, such as light or sound, changes direction when it passes from one medium to another. This phenomena is called refraction.
Experiment to try
What other images can you use for this trick?
How does it work
Learn why the pencil bends in the water.
Fun project to make
Try making one yourself. What can you do with it?
Episode J: Does a colour blind person see the world in black and white?
Episode J: Does a colour blind person see the world in black and white?
Colour mixing: Red, green and blue are primary colours. When they mix, different colours are formed.
Experiment to try
Try mixing various colours! What do you get?
Fun project to make
Is shadow always black?
Episode K: Which is heavier? Air pressing on a small table or an elephant?
Episode K: Which is heavier? Air pressing on a small table or an elephant?
Atmospheric pressure: Air pressure or atmospheric pressure is the force exerted against a surface by the weight of the air above the surface.
Experiment to try
Can you challenge your friend to blow the balloon?
How does it work
How heavy is the air exerted on a 1m x 1m table?
Fun project to make
Make a barometer to predict the weather!
Episode L: How do you help Captain America unscrew a very tight lid?
Episode L: How do you help Captain America unscrew a very tight lid?
Thermal expansion: Material, such as air, expands when it is heated.

How does it work
Why do bridges move? See how thermal expansion affects structures.
Fun project to make
Make your own thermometer!
Episode M: Can a person drown in the Dead Sea?
Episode M: Can a person drown in the Dead Sea?
Float or sink: An object will sink if it has a higher density than the fluid (liquid or gas) it is in. If it has a lower density, it will float.
Experiment to try
How do you make the egg sink or float?
How does it work
How does density determine whether an object floats or sinks?
Fun project to make
Why does hot air rise?
Episode N: Can you make ice-cream without a freezer?
Episode N: Can you make ice-cream without a freezer?
The Freezing / Melting point of water is 0 degrees celsius. Salt can lower the freezing / melting point.
