NCERT activity 1.6 class 9 science explanation with a conclusion so that you can
attempt questions based on the activity 1.6 class 9 science.
Activity 1.6 Class 9 Science
· Play this game in the field make four groups and form human chains as suggested
· The first group should hold each other from the back and lock arms like Bihu dancers
· The second group should hold hands to form a human chain
· The third group should form a chain by touching each other with only their fingertips
· Now the fourth group of students should run around and try to break the three human chains one by one into as many small groups as possible
· Which group was the easiest to break? Why?
· If we consider each student as a particle of matter, then in which group do the particles hold each other with the maximum force?
Observation Activity 1.6 Class 9 Science
When the fourth
group of students try to break the three human chains, they can break the chain
of those human beings easily which are formed by touching each other only with
their fingertips.
The first group
which is formed like Bihu dancers has the strongest forces they are
tightly held.
The second group
formed by holding their hands was the next strongly held whereas the third
group which is formed by just touching their fingers was the most weakly held. this
human chain was the easiest to break.
Conclusion Activity 1.6 Class 9 Science
Through this
activity, we can understand the force acting between particles can be
understood easily. The particles which are held tightly have the strongest force
of attraction. While the particles of those substances which have a weak force of
attraction can be separated easily.
Questions based on active 1.6 class 9 science
1. What do you conclude from activity 1.6?
Ans. – This activity shows that substances having a strong attraction force between them can’t be broken easily.
2. If consider each human being a particle of matter, then in which group do the particles hold each other with a strong force of attraction?
Ans. The first
group in which human beings formed a chain like Bihu dancers have a strong force
of attraction.
