After Dalton got modern atomic theory rolling in the early 1800s, a series of discoveries followed that resulted in its adjustment and refinement. Throughout the remainder of the 19th century and into the 20th, many scientists and inventors contributed to the further development of atomic theory. This collection introduces students to aspects of the Standard Model of Physics. Students will learn about the smallest fundamental particles that we know as of today. The aim of this collection is to have students explore and synthesize ideas from a variety of sources to enhance their understanding of and pique their curiosity about the composition of atoms and raise their awareness of how our ideas of these once indivisible particles have changed over time.
