The key to engaging students is to stimulate their curiosity and creativity, making learning fun. In fact, our team of passionate and experienced teachers have spent years of doing just that - a passion for science and its applications, whether in everyday life or a faraway future, come in handy to inspire a child to learn more about Science.

TEACHING APPROACH

When it comes to teaching methodology, we look towards developing the 5 'E's in each of our students. These are the five key tenets of our approach to Education.

ENGAGE

Here, we engage our students and grab their attention before we start going through the topic by having:

• Demonstrations of Experiment

• Getting students to ask essential questions

• Discussions based on the students' initial understanding of the topic to make connections between past and present learning experiences

EXPLAIN

Once we have gained our students' attention, we start to:

• Explain the concepts involved in the experiments or videos watched

• Determine levels of understanding and identify possible misconceptions

• This is done via the use of our specially designed Just Science notes

EXPLORE

Next, we get them directly involved with the topic and materials and start on their exploratory journey by:

• Doing Exploratory Activities

• Conducting Science Practical Assessments (SPA)

• Viewing videos specially selected to invoke students' interest and at the same time educate them

ELABORATE

EVALUATE

Here we extend our students' understanding by:

• Expanding on the concepts they have learned

• Making connections to other related concepts

• Applying their understanding to the world around them

Finally, at the end of the lesson, we evaluate our students' understanding via the following:

• Checking of answers

• Evaluation of Science Practical Assessments (SPA)

• Clarification of common misunderstanding of concepts

• Reinforcement of concepts

• Recapitulation based on the students' unique needs

This is done by exposing them to:

• Database questions

• Contextual questions

• Higher order thinking skills questions

• Short quizzes

Primary

Upper Block - Interactions - Adaptations

Example

The diagrams below show an African elephant and an Asian elephant.

African elephant

Asian elephant

a.) Based on the diagrams above, how are the two elephants different?

Explain how this difference is useful for the elephants. (3m)

Show Solution

The African elephant has a larger pair of ears than the Asian elephant. (1m) This increases the surface area exposed to the surroundings (½m) and will help to radiate excess heat from the elephant's body more efficiently (½m) to keep its body cool. (½m) This is necessary as it lives in the African grassland which has a higher average temperature (½m) than the rainforest where the Asian elephant lives.

b) How has the elephant adapted itself to obtain food and water? (2m)

Show Solution

The trunk of the elephant is made up of many strong muscles (½m) that enables it to pick up its food. (½m) The trunk also allows the elephant to suck up water (½m) to blow it into its mouth for drinking. (½m)

Upper Block - Interactions - Forces

Example

"Unlike most mammals, most adult dolphins do not have hair on their bodies other than a few hairs on their beaks which they will lose around the time of birth."

a) How does the lack of hair benefit the dolphin's movement? (1m)

Show Solution

The lack of hair on the skin of the dolphin decreases the surface area in contact with the water, (½m) reducing friction / water resistance. (½m) Hence, the dolphin will be able to swim faster.

b) Explain how wearing a swim cap and a full-body swimsuit enables a swimmer to swim faster. (2m)

Show Solution

Competitive swimmers often put on swim caps and wear full-body swimsuits as shown in the diagram below.

Putting on a swim cap and a full-body swimsuit covers the hair on the swimmer's head and body (1m) which reduces the surface area in contact with the water. (½m) Hence, with reduced friction / water resistance, the swimmer will be able to swim faster. (½m)

Electromagnetic Induction (Sec 4 Physics)

Example

a) There are no transformers that are 100% efficient due to energy loss caused by induced currents in the iron core known as eddy currents.

ai) State the effect that eddy currents have in a transformer.

Show Solution

It causes the transformer to heat up.

aii) Suggest how energy loss due to eddy currents can be reduced.

Show Solution

Use thin sheets of soft iron that is laminated by a layer of insulation.

Although eddy current is not desirable in the design of the transformer, it has been used in the induction stoves.

Induction stoves work by using coils of copper wire placed under a cooking pot which is connected to an alternating current as shown below. This produces an alternating magnetic field which cuts through the cooking pot.

In recent years, induction stoves have been gaining popularity due to the fact that it is much safer than a gas stove. One does not have to worry about getting burnt by the stove during cooking. Even after cooking, the stove remains relatively cool which makes it safe to touch.

bi) Explain how the induction stove is able to heat up the cooking pot.

Show Solution

The constant change in the number of magnetic field lines through the cooking pot induces eddy current in it. This causes large amount of thermal energy to be produced, thus heating up the cooking pot.

bii) With the cooking pot on top of the stove, the induction stove is effectively a step-down transformer as the coil of copper wire has many turns and the cooking pot is effectively a single short turn of coil.

Explain why the induction stove is designed with a step-down configuration

Show Solution

With a step-down configuration, the voltage in the cooking pot is smaller than in the copper wires. This increases the induced current in the cooking pot. As power loss is greater with higher current, most of the electrical energy would be converted to thermal energy in the cooking pot, allowing faster increase in temperature.
