What did the Apollo 11 collect on the moon?

Apollo 11 collected a variety of samples from the Moon, including about 47.5 pounds (21.5 kilograms) of lunar rocks, soil, and core samples. The astronauts also brought back moon dust and conducted experiments, such as deploying the American flag and setting up scientific instruments. These samples have provided valuable insights into the Moon's geology, formation, and the history of the solar system. The lunar samples are still studied today to enhance our understanding of planetary science.
