Changes

* The soil for the plants in the cupboard was damp.

* The pots on the windowsill were hot to the touch.

: The results did not match the prediction based in our textbook. The method was not good because the soil on the windowsill went dry because of the warmth and sunlight but the soil in the cupboard stayed damp. This meant sunlight wasn't the only difference between the two groups of cress. To improve the experiment both sets of plants should be watered to keep the conditions the same and to make sure they also have enough water to grow.
