Mastereign Little Newton
Primary Three
| Boats | ||
| (Buoyancy) | ||
| Why are boats able to float in the sea? If there are two boats of different sizes, which one can carry more goods? In this lesson, students will learn that buoyancy is the ability of an object that allows it to float in water. Objects like the boat will sink if the effect of gravitational force is greater than its buoyancy and it will float upwards if its weight is less than its buoyancy. Students will also be able to apply this understanding in their lives when they go swimming and go for cruises.
Key Scientific Terms: Buoyancy, Loading Capacity and Surface Area. |

| Balloon-Powered Helicopter | ||
| (Action and Reaction) | ||
| Newton’s Third Law of Motion states that for every action, there is an equal and opposite reaction. This principle, like all the other theories from Sir Issac Newton applies even with simple actions like clapping our hands. Through this lesson, students will learn about aerodynamics and how the action of air escaping from the balloon can cause the helicopter to go on flight. Students will be given items like balloons, propellor blades and connectors to construct their own helicopters that goes up, up, and away! With this knowledge, students will be able to start noticing action and reaction at work in their daily lives!
Key Scientific Terms: Elastic Potential Energy, Kinetic Energy and Aerodynamics. |

| Ants’ Kingdom | ||
| (Insects) | ||
| Ants are insects that can be found almost everywhere on Earth and can lift more than twenty times its own body weight. Students will step into the fascinating world of ants in this lesson. They will learn that ants, like all insects, have three main body parts and the 4 types of ants: queen ants, male ants, worker ants and soldier ants. Students will be able to compare and contrast the different types of ants, analyse their findings and communicate them when they complete this lesson.
Key Scientific Terms: Ants’ Behavioural Patterns and Entomology (Insect Biology). |
||
| Interesting Solenoids | ||
| (Electromagnetism) | ||
| Electromagnets are “temporary magnets” that have the properties of magnets only when there is a current is flowing around it. With the aid of an intricate apparatus, students will be able to construct a complete electric circuit, which can be used to electrically magnetise a metallic object! With the apparatus, they will be able to control the magnetic property of their electromagnets by energizing or de-energizing it as and when they want. This lesson will generate curiosity and interest of students in magnets and their use in everyday objects such as electric bells and trains.
Key Scientific Terms: Electromagnets, Electromagnetism and Electric Circuit. |

| Human Skeleton | ||
| (Human Body Knowledge) | ||
| In this lesson, students will learn about the human skeleton and how it works. Students will be able to fix up their own skeletal system and understand that the human skeleton consisting of three parts: the skull, the truncal bones and the limb bones. They’ll learn about the functions of the human skeleton will allow students to better understand themselves and ultimately gain interest in health care education. Students will then be able to analyse and take charge of their bodily needs, exercise regularly and have balanced diets that include Vitamin D and Iron!
Key Scientific Terms: Human Skeletal Structure/ System. |
||
| Seed Germination | ||
| (Plants/ Phytobiology) | ||
| Through this lesson, students will learn to appreciate nature and be little Biologists. They will learn interesting facts about plants, for instance, that seedlings are more robust in an environment with sufficient sunshine compared to those that grow in shady places. Students will then be able to grow their own seeds and begin conducting experiments so as to compare the life cycles of various seeds in different conditions. Students’ observation skills will be enhanced as they record their findings over a period of time and bring their learning out of the classroom.
Key Scientific Terms: Seeds, Seed Germination, Seedlings, Sunlight, Moisture, Humidity and Temperature. |

| Pop Gun | ||
| (Air Compression) | ||
| Air is colourless and odourless and we can hardly feel its existence unless there is wind. In this lesson, students will be able to explore this important matter that keeps us alive each day. They will use apparatus like plastic syringes and plastic tubings to construct their very own pop guns that can produce a loud ‘pop’ sound under the effect of air compression. Students will be able to examine how the ‘pop’ sound is created and infer that although air is light, it can exert powerful pressure. This will also allow students to investigate energy conversion and sound energy that are present in our everyday lives.
Key Scientific Terms: Air Compression, Sound Energy and Energy Conversion. |

| Self-Formulated Toothpaste | ||
| (Chemical Reaction) | ||
| To be able to enjoy our food, we need to clean our teeth daily with toothpaste to have strong and healthy teeth. In this exciting lesson, students will be exposed to a hands-on activity of formulating toothpaste using a mixture of ingredients consisting of water, abrasive, decontaminating, thickening and wetting agents as well as sweetening and flavouring chemical agents. This will be a lesson that will allow students to enhance many process skills such as observing, formulating hypothesis, analysing and evaluating if their experiment works in order to achieve their desired results – a successful toothpaste!
Key Scientific Terms: Thickening Agent, Coagulation, Decontamination and Anti-Microbial Agent. |
