Thomson's cathode-ray tube experiments helped scientists learn about electrodes and that atoms were comprised of many small particles, which they did not know existed. They also learned from this tube that all the electrons were the same regardless of what elements they came from.

How do scientists learn something new from controlled experiments?
they use controlled experiments to help them find out if it works or not.
How do experiments help scientist learn about the world?
experiments test the scientist theory
What kind of experiments do scientists do on mummies?
Scientists do not do experiments on Egyptian mummies, they study them to learn about those people. They do x-rays, computed tomography, and other nondestructive imaging so they can understand how they lived, what their health status was, and how they died.
