Build toys and learn science
.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?
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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

Thermal expansion: Material, such as air, expands when it is heated.

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.

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.

Episode O: Is green really green?
A lot of food dyes are water soluble. You can separate the food dyes with water. This technique is called chromatography.
