High School Science Experiment Ideas - ThoughtCo

A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles, and stainless steel balls.

In 1866, Mendel published the paper Experiments in plant hybridisation (Versuche über plflanzenhybriden).In it, he proposed that heredity is the result of each parent passing along 1 factor for every trait. If the factor is dominant, it will be expressed in the progeny.If the factor is recessive, it will not show up but will continue to be passed along to the next generation.
