Brilliant experimental physicist and one of the founders of nuclear physics
Rutherford used a vacuum in his experiment to eliminate any air molecules that could interfere with the path of the alpha particles. This allowed him to study how the alpha particles interacted with the gold foil and draw conclusions about the structure of the atom.
A manipulated variable is the thing that can be changed in an experiment. example; your trying to see what paper towel would be more absorbant, your manipulated viariable would be either the type of paper towel you use or the liquid you use to test the absorbancy.
Einstein used the photoelectric effect to conduct his experiment that helped support the theory of quantized energy. By shining light on a metal surface, he observed that electrons were emitted when the light reached a certain frequency, providing evidence for the particle-like behavior of light.
You can conduct an experiment using different materials (e.g. metal, wood, plastic) exposed to sunlight and measure their temperature increase over time. The material that shows the highest temperature rise is a better absorber of heat. Alternatively, you can use a heat lamp and measure the temperature increase on different surfaces to determine which one absorbs heat more efficiently.
To expand metal effectively and safely, use techniques such as heating, stretching, and hammering. Ensure proper safety precautions are taken, such as wearing protective gear and working in a well-ventilated area. Additionally, follow guidelines and instructions specific to the type of metal being expanded.
How about a ton of drawings and illustrations? Use the link below and there will be more than you can do. By the way, the experiment is usually called the Geiger-Marsden Experiment as it was done by these two researchers. There is a link to the Wikipedia post on this experiment below as well.
Radium was used in Rutherford's experiment to act as a source of alpha particles. The lead box was used to shield the experiment from external sources of radiation interference, allowing for more accurate measurements of the alpha particles' behavior.
Niels Bohr used copper in his experiment on the electromagnetic radiation emitted by metals when heated.
Rutherford's experimenters were Hans Geiger, and Ernest Marsden, both of whom went on to have worthwhile science careers. The metal foil used in the Rutherford experiments was gold, for this foil amy be made extremely thin by careful beating, whilst still being imperforate.
dalton wasnt the one who experimented with gold, rutherford was the one who did the gold foil experiment.

The best type of glue to use for bonding glass to metal is a clear epoxy adhesive.

Not metal! I don't know what type you REALLY use though. But not metal cleats.
For drilling into metal, you should use a cobalt drill bit.
