Science CurriculumFramework

The science curriculum seeks to nurture the student

as an inquirer. The end goal is for students to enjoy science and valuescience as an important tool in helping them explore their natural and physical world.

Objectives of workshop

Sharing on how we can leverage theopportunities and phenomenon aroundus, in facilitating and engaging our kidsas inquiry learners with curious minds.


Teaching and Learning through Inquiry

• Learning science as inquiry must gobeyond merely presenting facts and reporting of data.

• Pupils must be actively engaged • collecting and using of evidence• formulating and communicating

explanations based on scientific knowledge


What do we want to achieve?

We want to�tickle their interest and wanting to

understand their surrounding;

�get them to think deeper and

�discuss their thoughts with others and build on their current understanding.


When students get an early start doing “real” science, they begin to see science simply as a way to examine the world by

asking questions.

Also, empowering students to contribute to the body of scientific knowledge helps develop a personal, vested interest in

science.

Science in Everyday Life


How can wesupport

their learning?

Engage them: Ask instead of

answering questions

Have a curious mind –explore together

Create a positive and safe environment


Difficult?How?

It’s Sunday afternoon and you are sitting in your man chair, in your man robe, reading your man newspaper. It’s your wife’s turn to cook today.

To keep things simple, she’s whipping up some spaghetti and a nice side salad to go with it. And then you hear it:

“Dear, I can’t get the lid to the spaghetti sauce jar to open. It’s stuck. Can you open it for me?”

Are you ready for moments like these?

Discuss:1) What is the concern?

2) Why is this measure necessary?

3) What else is Singapore doing to deal with the issues?

4) As individuals, what can we do?


How do these help to save water? (Hint - link to “matter occupies space”.)

I see… I think…

I wonder ...

A water tank used for flushing a toilet bowl is shown below. The flushing and re‐filling system is not shown in the diagram,

After flushing, water enters and refills the tank. The water will stop filling if water reaches level L.

James wanted to use less water to flush the toilet. Michelle suggested using plastic bottle filled with stones.

SAMPLE PSLE QUESTION – OEQ

Concept : Properties of matter

Topic : Matter



Oil spill on the road –what are

problems it will cause?


What are the problems we might be able to solve if this is true?


Skills and Processes to link

Science Ideas


Basic Process Skills (to link Science ideas)

To answer questions well, students need to:

✓ Remember: Possess science knowledge

✓ Understand: Understand science concepts

✓ Analyse, Apply: Link science concepts Evaluate, create

✓ Communicate: Express science ideas clearly


Samples of real-life application

Questions

SAMPLE QUESTION – OEQ

(c) Which material, W, X, Y or Z is most suitable to be used to make the handle of a frying pan? Give a reason for your answer.

handle


Thought process

1. WHAT IS THE QUESTION ASKING ABOUT? ‐Material of handle

1. WHY SHOULD THE MATERIAL OF THE HANDLE BE DIFFERENT (FROM THE PAN)?

– you do not want to be scalded with you hold it

2. HOWCAN THEY PROTECT THE USER FROM BEING SCALDED?– to use material which is the poorest conductor of heat.

A water tank used for flushing a toilet bowl is shown below. The flushing and re‐filling system is not shown in the diagram,

After flushing, water enters and refills the tank. The water will stop filling if water reaches level L.

James wanted to use less water to flush the toilet. Michelle suggested using plastic bottle filled with stones.


Concept : Properties of matter

Topic : Matter



(a) Explain how Michelle’s suggestion would help reduce the amount of water used to flush the toilet?

Concepts on MatterMatter has mass.Matter occupies space.Bottle and stones are matter.

Thought process

1. WHAT IS THE STATE OF THE PLASTIC BOTTLES? WHAT CAN THEY DO?‐ They are solids which occupy the space.

1. WHY DOES THIS DECREASE THE AMOUNT OF WATER USED?– The space for the water to take up initially has been occupied by the bottles

1. HOWWILL THIS AFFECT THE AMOUNT OF WATER USED?– Less water is needed to fill up the water tank to level L


Concept : Property of gas

Topic : Matter

Potato chips are packed in air-tight bags containing a special gas. The packets are stacked tightly in cartons during transportation.

Based on the properties of gases, describe one advantage of the gas in the bag during the transportation of the chips.


Thought process

1. WHATMIGHT HAPPEN WHEN YOU TRANSPORT CHIPS IN A BAG?‐ Chips will get crushed when they are packed together.

1. HOWDOES HAVING AIR IN IT PREVENTS THAT FROM HAPPENING?

2. WHAT ARE SOME PROPERTIES OF AIR THAT CAN HELPS IN THIS?– Air occupies the space in the bag ‐ Air prevents the solid from contacting each other easily.

SAMPLE PSLE QUESTION – OEQApplication (applying concepts to real world situation)

Concept : Arrangement of

light

Topic : Electrical Systems

Thought process

1. WHAT ARE THE DIFFERENCES BETWEEN A SERIES AND PARALLEL BULB ARRANGEMENT?

2. HOWDOES EACH ARRANGEMENT AFFECT THE BRIGHTNESS OF THE LAMP?

3. WHY DO THE OTHERS NOT BE ABLE TO PRODUCES THE STRONGEST HEAT?



Nancy helped her mother wash the plates after dinner. She placed the wet plates, one on top of another as shown in Figure 1 and let them to dry.

Nancy’s mother told her that the plates would dry faster if she placed them on a rack as shown in Figure 2.

Concept : Rate of evaporation

Topic : water

(a) Give two reasons why the plates in Figure 2 would dry faster than those in Figure 1.

Thought process

1. WHAT ARE THE DIFFERENCES BETWEEN THE METHOD OF DRYING IN FIG 1 AND 2?

‐ Figure 1’s plates are stacked while figure 2’s plates are placed apart.

1. HOWDOES EACH ARRANGEMENT AFFECT THE RATE OF EVAPORATION?

‐ Figure 1’s method reduces the amount of exposed surface area of each plate with contact to the surrounding heat and wind.

2. WHYWILL EACH ARRANGEMENT RESULT IN THE DIFFERENCE?‐ A greater exposed surface area will increase the rate of evaporation.

Esther noticed that her father poured hot tea from one cup to the othercontinuously for a few times as shown in the diagrams below. Her fatherexplained that the hot tea will cool down more quickly after it was “pulled”several times.

SAMPLE QUESTION – OEQ


Concept : Heat Loss

Exposed Surface Area

Topic : Heat

Explain why the hot tea will cool down more quickly this way.

Exposed Surface Area

(a) Explain why the hot tea will cool down more quickly this way.

Thought process

1. WHAT IS THE DIFFERENCE OF COOLING A TEA IN A CUP COMPARED TO COOLING IT BY PULLING THE TEA?

‐ Exposed surface area has increased

1. HOWDOES THIS HELP TO COOL IT FASTER?‐ It loses the heat to the surrounding air quicker

When the milk tea was “pulled”, there is an increase exposed surface area of the milk tea. Hence the milk tea lost heat to the surrounding air more quickly.
