🔬 Experiment: Which Type of Ice Melts the Fastest?
Scientists wanted to find out whether the size of an ice cube affects how quickly it melts.
They used three ice cubes made from the same water. The ice cubes were different sizes: small, medium, and large.
The scientists placed each ice cube on a separate plate. The plates were kept in the same room at the same temperature. The scientists started a timer when they placed the ice cubes on the plates.
Every 5 minutes, they observed the ice cubes and measured how much ice was left.
After 20 minutes, they recorded these results:
- The small ice cube had melted completely.
- The medium ice cube had 25% of its ice left.
- The large ice cube had 50% of its ice left.
What was the purpose of this experiment?
To find out whether the size of an ice cube affects how quickly it melts.

📊 Passage 6: Climate Change Argument
Many scientists argue that human activities contribute to climate change. Burning fossil fuels releases carbon dioxide into the atmosphere, which traps heat. This process, known as the greenhouse effect, leads to rising global temperatures. Some people argue that climate change is part of a natural cycle, but most scientific evidence supports the idea that human actions play a significant role.
