Radioactive Isotopes, History, Subatomic Particles, Model of the Atom, Atomic Theory | Middle School, High School
Video: Ernest Rutherford Video
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.

Limiting Reactant, Balancing Equations, Stoichiometry, Observations, Chemical Change | High School
Lesson Plan: Observing the Limiting Reactant
In this lesson, students will be introduced to the concept of limiting reactants by applying various literacy strategies to a one-page informational text and through a short demonstration (or lab). The reading and demo will help students create connections between the macroscopic, particulate, and symbolic representations of chemical reactions and limiting reactants.

Calorimetry, Exothermic & Endothermic, Temperature, Stoichiometry, Limiting Reactant, Chemical Change, Molarity, Enthalpy, Heat, Concentration, Experimental Design, Scientific Method | High School
Lab: Less Than Zero
In this lab, students will investigate the endothermic reaction between baking soda and HCl. Students will consider stoichiometric ratios, molar concentrations, reaction scale, and calorimetry. The lab starts with a scripted reaction that uses given molar ratios, a glass beaker, and 2-M HCl. They will witness a temperature drop of about 5 to 8 C. Students then adjust the experiment so they can achieve a temperature drop of more than 20 C.
