- Counting the number of people in the group
- Identifying shapes of the rocks and surroundings
- Comparing the depth of the water at different points
- Measuring the temperature of the water using a thermometer
- Estimating the distance from one end of the spring to the other
Continued development can include introducing the concept of volume by measuring the amount of water displaced when someone jumps into the spring. The child can also practice addition and subtraction by counting the number of people entering and leaving the spring. Additionally, they can learn about fractions by dividing the spring into equal parts and identifying how much of the spring each person is occupying.
