📖 Read the story
Forensic science is a special kind of science. It helps the police solve crimes. These scientists are like detectives. They look for clues like fingerprints. Recently, scientists did an experiment with fake blood. They wanted to see how liquid falls. They dropped the red liquid from different heights onto the floor. They looked at the red marks, or stains. When the liquid falls from very high, the stain is big. When it falls from a low place, the stain is small. This helps them know what happened. They use physics to study this. Physics is the study of how things move. It is like being a detective with a ruler! You can try this at home with red paint and water. It is fun to see the different shapes. Do you want to be a science detective?
