Cause and Effect Identification

Emma had been working on her science fair project for weeks. She wanted to investigate how different types of music affected plant growth. Because she was so excited about her experiment, Emma started her project earlier than most of her classmates.

Emma set up three identical plants in separate pots. She placed them in the same sunny spot and watered them equally. However, each plant was exposed to different conditions: one listened to classical music for two hours daily, another heard rock music for the same duration, and the third grew in complete silence.

After forgetting to water the plants for three days during the school holidays, Emma noticed the leaves on all three plants had turned brown and droopy. She felt terrible and immediately began a regular watering schedule. Within a week, the plants had recovered.

By the end of the experiment, Emma discovered that the plant exposed to classical music had grown 3 centimetres taller than the others. Because of these impressive results, Emma won second place at the science fair. Her success inspired her younger brother to enter the fair the following year.
