Science Misconceptions on States of Water

When we boil water, we see "white clouds" coming out of the spout of the kettle. What are the white clouds?

Misconception:
The "white clouds" are steam.

Correct concept:
The "white clouds" are condensed water droplets. They are formed when the steam meets the cooler air in the surroundings, lose heat and condense to form water droplets.
The "white clouds" are not steam. Steam is in the gaseous state and cannot be seen.

Science Misconceptions on Respiration

Misconception (1):
Breathing is the same as respiration.

Right concept: 
Breathing is the exchange of gases between the air and our bodies. On the other hand, respiration is the process by which oxygen is used to break down food to provide our body with energy.

------------------------------------------------------------------------------------------------------
Misconception (2):
Plants carry out respiration only at night.


Right concept: 
Plants carry out respiration all the time, even when they are photosynthesising.

Science Misconceptions

Is breathing the same as respiration? Can we use the terms "respire" and "breathe" interchangeably?

Children have certain misconceptions about Science. As educators and parents, it is useful to know these misconceptions so that we can lead the kids in the discussion on these misconceptions. We can also gear our lessons or discussions towards clarifying these misconceptions.

I will be sharing some of these common misconceptions in this blog. You may want to test them out on your kid and see if he or she has these misconceptions too.
