What did you observe about the mustard seeds?
Mustard seeds flow from the highest point of the slope downward. They do not move in a perfectly straight line but follow the shape of the folds in the paper.
The seeds spread out in different directions and collect in the lower areas and valleys formed by the crumpled paper.
Explanation
Activity 6 uses mustard seeds to demonstrate how water flows. The seeds represent water and show how water flows from higher to lower ground, following the shape of the land. The seeds collect in low areas just like water collects in lakes and rivers.
