Today, we started to look at the process of osmosis. Sadly, the wet weather meant we could not do our experiment outside, so we will do it tomorrow.

Osmosis helps explain how water gets absorbed by the roots of plants. This is the first step in the water getting to the leaves.

In our experiment, we found that the potato chip in the saline solution became really bendy (flaccid). We think this is because water was lost from the potato into the saline solution it was soaking in. The potato chip in the tap water became really hard (turgid). We think this is because the potato absorbed some tap water. These are both examples of osmosis in action.
