Lesson Plan: Chemical Measurement Unit Plan Mark as Favorite (115 Favorites)
The AACT High School Classroom Resource library has everything you need to put together a unit plan for your classroom: lessons, activities, labs, projects, videos, simulations, and animations. We constructed a unit plan for introducing concepts student need to collect and use chemical measurements: Percent Composition, Metric Units, Accuracy and Precision, Percent Error, Density, Scientific Notation, Significant Figures, and Unit Conversion. This unit is designed to be used at beginning of the school year and modified based on student math abilities.

Video: Ernest Rutherford Video Mark as Favorite (71 Favorites)
Rutherford's initial research was studying alpha particles, which he hypothesized were helium nuclei. With the help of Hans Geiger, Rutherford conducted the gold foil experiment, which justifies that the nucleus of an atom is a dense collection of protons and contains the majority of an atom’s mass. It also inferred that most of the atom is empty space and electrons are not located in the nucleus. He won the Nobel Prize in chemistry in 1908 for his studies on radioactive substances.
