1. Find an empty space near your classroom, it could be a corridor or any other empty space. The only condition is that you should be able to walk and take at least 20 steps naturally.
2. Mark a starting point to begin your walk.
3. Measure 10 meters from this point. That will be the end point of the walk.
4. Walk on it a couple of times.
Is your step count always the same?
Now walk on the path 10 times and make a table to record the data. Every time count your steps and fill in the data in the table given below.

Table 1.4: Step Count
Has your step count been varying a lot?
Is there a range within which these numbers fall?
You have done an important finding - "The range".
The range helps you to predict that if you walk the distance 11th time, the number of steps you will take to cover the same distance will be within the range.
Walk another 5 times on the path to test if your prediction was right or wrong.

Make your step your scale
Material required:
1. Empty space to walk
2. A paper tape
3. Chalk/Marker
Process to do the activity:
1. Find an empty space near your classroom, it could be a corridor or any other empty space. The only condition is that you should be able to walk and take at least 20 steps naturally.
2. Mark a starting point to begin your walk.
3. Measure 10 meters from this point. That will be the end point of the walk.
4. Walk on it a couple of times.
Now walk on the path 10 times and make a table to record the data. Every time count your steps and fill in the data in the table given below.
