KEY UNDERSTANDINGS
**RUBIX CUBE"
I can ask one question related to a topic
I can ask several questions linked to the topic
– I can ask several questions liked to the topic and explain the difference between open and closed questions
– I can ask several questions linked to the topic and explain the difference between open and closed question.
THINKING AND MAKING CONNECTIONS
I need help to ask a question
ACHIEVEMENT OBJECTIVES
Nature of Science - Investigating in Science, Communicating in Science, Participating and Contributing
Physical World –
Seek and describe simple patterns in physical phenomena.
Ideas for Possible Future Learning
Place Based Learning
Field trip to local pond
Pond Skaters
What can we see that is floating on the water
+ve / -ve attraction
Density
Adding elements
what if?
What if we put a different object in the water?
Paperclip
what if there was no surface tension in the world
what if we change a variable?

Effect of Impurity and Chemical
changes nature of the bonding between the molecules changes.
Example:
When common salt is dissolved in water, the surface tension of the saltwater is more as compared to water.
Example:
The addition of detergents, soap as well as phenol decreases the surface tension of water.
Effect of Temperature
The surface tension of liquid decreases by increasing temperature. If the temperature increases, the average separation b/w the molecules increases & due to that the cohesive force decreases.
The surface tension of liquid becomes zero (0) at a particular temperature known as the critical temperature of that liquid.
WHY?
Bringing the study into real world - i.e why don't boats sink if horizontal?
