Primary Two
| Maze-Running Game | ||
| (Magnets) | ||
| Through this lesson, students will be able to understand that magnets have two poles: the North and the South pole. They will explore the attraction and repulsion between poles and the different types of material that allows magnetism to pass through. The Maze-Running game is a mini competition where students are challenged to manoeuvre their magnetic items through a cardboard maze in the shortest possible time without falling into the traps. Students will learn through the findings derived from the game.
Key Scientific Terms: Magnetic Attraction, Magnetic Objects, Non-Magnetic Objects. |

| Lighting Up a Small Electric Bulb | ||
| (Electric Circuit) | ||
| This lesson allows students to learn about how an electrical circuit works using apparatus such as batteries, battery boxes, tungsten light bulbs and bulb holders. They will also begin to learn about chemical potential energy, electric currents and open and closed circuits. The experiment allows students to gain confidence via trial and error in order to achieve their desired result.
Key Scientific Terms: Batteries, Insulated Copper Wires, Chemical Potential Energy, Electrical Energy (Electricity), Light Energy, Heat Energy, Tungsten Bulb, Electric Switch. |

| Boomerang | ||
| (Air Resistance) | ||
| The Boomerang intrigues people because of its ability to deliver itself back to the thrower. In this lesson, students will discover that the trick in a returning boomerang lies in its design, which is usually flat and curved and allows for self-rotation. Students will learn that force is required to start the flight of a boomerang and the relationship between the throw, thrust, wings, lift, spin and stability of a boomerang. This popular lesson allows student to practise the process skills of experimenting, performing trial and error and problem solving to be able to throw and receive their boomerangs swiftly!
Key Scientific Terms: ey Scientific Terms: Boomerang, Air Resistance, Gravity. |

| Wind Vane | ||
| (Wind Energy) | ||
| Wind cannot be seen but we feel the effects of wind when it shakes trees and messes up our hair. In this lesson, students will learn that wind is the flow of air on a large scale and that the speed is the horizontal distance that the air has flowed within a unit time. Students will assemble a wind vane that can determine the direction in which wind is blowing from and learn about the eight different wind directions.
Key Scientific Terms: Wind Energy, Kinetic Energy and Wind Direction. |

| Illusion | ||
| (Conceptual Thinking of Vortex) | ||
| When we carry one kilogram of cotton and one kilogram of iron, we will feel that somehow, the iron is heavier than the cotton. When we are sitting on a moving train, it often looks as though the trees outside are running backwards. These phenomena are distorted perceptions called illusions. In this lesson, students will learn about the interesting way that humans perceive and study various kinds of illusion, such as optical illusions, illusions on space, time and movement. Students will be amazed when they observe a series of patterned and complex pictures which can induce virtual illusion.
Key Scientific Terms: Virtual Illusion. |
||
| Paper Bridge Experiment | ||
| (Civil Engineering) | ||
| Do bridges that are used by large number of people and vehicles need to be huge in terms of volume and weight? Through this lesson, students will discover that several sheets of paper and paper cups can support weight greater than what they would expect. Students will learn that bridges are able to withstand tremendous pressure due to the compression and tension force acting on them. They will also explore and understand various types of bridges such as arch, suspension and beam bridges. Students will practise hypothesizing and enhancing their creativity skills as they construct their own bridges.
Key Scientific Terms: Bridges, Civil Engineering, Construction. |
||
| Paper Tube Elevator | ||
| (Gravitational Force) | ||
| A world without elevators will be unimaginable and inconvenient. In this lesson students will learn how this amazing invention came about and how an elevator actually works through the construction of a model of an elevator which rises up and down under the effects of pulling force and gravitational attraction force. Students will also be able to understand the effects of gravity and how energy is transferred between complex machines that we use in our daily lives.
Key Scientific Terms: Gravitational Force, Pulling Force, Attraction Force and Mechanical Energy Transfer. |
||
| Tiny Somersaulting Capsules | ||
| (Centre of Gravity) | ||
| Not everybody can perform a proper somersault, but our amazing capsule can! In this lesson, students will be able to use apparatus like steel balls, capsules and a cardboard to construct their magical capsules that can somersault down a slope! Students will learn that the steel ball is round so it can roll freely around the capsule, yet, it is heavier than the capsule so when the ball rolls over to the other side of the capsule, the capsule’s centre of gravity changes. Then, the other side of the capsule will rise, making the steel ball roll about constantly and thus perform somersaults like an acrobat! Students will now be able to fully understand the concept of centre of gravity and explain how it is found in our everyday lives!
Key Scientific Terms: Gravitational Force, Stability and Centre of Gravity. |
