Ms Screeney's  5th class learned about plants before Christmas.  One of the two activities they undertook was to investigate the ideal conditions for cress to grow.  They made predictions based on previous knowledge. The pupils suggested that plants need light, water and heat to grow. They were then asked to predict if any one of these were more important than the others. They designed the following test.
Cotton wool was place in 8 containers. Cress seeds were sprinkled in each of these. The containers were then subjected to the following conditions:
1 - Light & heat & water
2  - Light & heat & NO water
3 - light & cold & water
4 - light & cold & NO water
5 - dark and heat and water
6 - dark and heat and NO water
7 - dark and cold and water
8 - dark and cold and NO water

Each container was observed over a number of days and the results recorded. 

The container that had light, heat and water proved unsurprisingly to be the best conditions for the cress to grow. The most noteworthy aspect of the results show that in all cases where there was no water used, there was absolutely no growth.
