Cress Seed Growing

Our 2nd Class scientists recently carried out an exciting investigation to discover what conditions cress seeds need in order to grow. Before beginning our experiment, we made predictions and discussed what plants need to survive.

We set up three different groups of cress seeds:

Group 1: Soil, water and light (optimal growing conditions)

Group 2: Soil and light, but no water

Group 3: Water and light, but no soil

Over the following days, we carefully observed and recorded any changes. The children were fascinated to see that the cress seeds given water and light grew successfully, whether they were planted in soil or not. The seeds that had soil and light but no water showed very little growth, helping us to understand just how important water is for plants.

As part of our learning, we also researched the many uses of cress. We discovered that it is commonly used as a garnish and can be added to salads and sandwiches to give them extra flavour and texture.

The highlight of the investigation was undoubtedly our cress taste test! Once our cress had grown, the children had the opportunity to sample it. We described the taste as peppery and had lots of fun sharing our opinions. Some children really enjoyed the flavour and said they would happily eat it in a sandwich or salad, while others were not quite so keen!

With lots of care and attention, the children's cress seeds thrived! Take a look below at the growth they achieved!
