2. What are the differences between the two choices above?
3. Which of the above, a wollen sweater or a windbreaker, should she choose to bring along for her trip? 
4. Give reason(s) for your choice. 

Pack Light, Pack Smart

Why are people often being advised to pack light when they travel?

What do you know about Science that helps in packing light?

Explain how this is achieved.

Do you think that in Science, the packaged clothes are truly lighter?

Share your thoughts.

Not-so attractive flower after all!

Insects are attracted to brightly coloured flowers.

But, how can they tell colours when they are colourblind?     

More Stone Cooking

Watch Stone Cooking

I applaud your participation in this discussion - quite similar to the Chestnuts question in CA1.

"Stones can transfer the heat from the fire to the bread and will cook it." Jin Feng

"Metal pans conduct heat more quickly." Chong Boon and "conducts heat better than stones." (Quinn)

But all participants to this question state that "Stones are good conductors of heat".

But from the question on stones used in the sauna, Farid said,"Stones are bad conductors of heat, thus trap the heat and does not allow it to escape quickly."

How can we decide who is right?
Can you describe what makes a good heat conductor? That will guide us in this discussion. I await your responses.

Personalised SAM

 

Science Around Me (SAM)

SAM is a Science journal that allows pupils to express themselves in their favourite ways about Science.
SAM is another great opportunity for pupils to THINK and TALK Science in a medium that is customised to their learning styles.

SAM allows teachers to informally assess understanding of the child and clarify misconceptions in their learning.

Three States by Zacchaeus - 4F

If I could change my state into solid, I would turn myself into a hard metal box with a definite shape and one pair of hands and legs!

If I could change my state into liquid, I would chnage into a puddle of water with a definite volume and go to sea to unite with my friends!

If I could change my state into gas, I would become a genie with an indefinite state. I would go round and round and grant wishes for people. I would go into an air-tight jar and be compressed!

 

When Ice Changes into Water by Goh Chee Yan - 5G

Do you wonder whether the mass of ice changes when it melts into water. Try this out:
1. Put a few ice cubes into a plastic bag2. Tie the mouth of the bag tightly
3. Weigh the bag of ice cubes (if there is condensation outside the bag, wipe it dry before weighing)4. Place the bag in the sun
5. When ice has melted, wipe the outside of the bag dry (refer to step 3)6. Weigh the bag

You will discover that the mass of the bag remains the same!
There is no change in mass when ice melts!!
