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.

Acid & Base Theories, Strong vs Weak, History | Middle School, High School
Video: Acid & Base Guys Video
This video tells the story of how the definition of acids and bases has evolved from Lavoisier, to Arrhenius, Bronsted-Lowry, and Lewis.
-
Periodic Table, Elements, Introduction, History, Atoms, Electrons, Subatomic Particles | Middle School, Elementary School, High School
Activity: Writing Your Name using Chemical Element Symbols
In this activity, students will use their creativity to spell their name (first or middle name and their last name) using chemical symbols of elements on the periodic table. For example, you can spell Yvonne using the symbols for yttrium (Y), vanadium (V), oxygen (O), nitrogen (N), and neon (Ne).
-
Chemical Change, Strong vs Weak, Salts, Mixture, Acid & Base Theories, Conductivity, Ions | Middle School
Lesson Plan: Why Drink Gatorade?
In this lesson, students will test different flavors of Gatorade and other liquids to investigate acids and bases. This will take several days unless students already know about acids and bases.
-
Lab Safety | High School, Elementary School, Middle School
Activity: What Not to do in the Chemistry Lab
In this activity, students will examine a cartoon of a chaotic chemistry laboratory and note the specific behaviors that are dangerous and unsafe in a chemistry laboratory setting. This activity provides an opportunity for teachers to introduce laboratory safety and best laboratory practices and discuss them with their students.
-
Heat, Temperature, Specific Heat, Observations, Molecular Motion | High School, Middle School
Activity: What Makes Something Feel Warm
In this lesson students actively engage in thinking about energy issues in chemistry and the nature of energy (thermal) transfer. The idea that temperature is a measure of heat content will be challenged, and students will be given the opportunity to collect data that will allow them to clearly see that different materials transfer energy at different rates.
-
Temperature, Molecular Motion, Observations, Inferences | High School, Middle School
Demonstration: What is Temperature?
In this demonstration, students will observe food dye mixing with water at different temperatures.
-
Freezing Point, Phase Changes, Temperature, Physical Change | Middle School
Lab: Lemon Ice
This activity explores the interaction between salt and water (ice) as a way to further investigate their impact on the state of matter of a substance. Students will use salt and ice to create a slushy lemonade drink without the use of a freezer. They will learn through this hands-on experiment how salt and ice can rapidly cool a liquid.
-
Conservation of Mass, Exothermic & Endothermic, Chemical Change, Heat, Temperature, Observations, Chemical Change | High School, Middle School
Lab: Kitchen Reaction
In this lab students will observe an endothermic chemical reaction involving baking soda (sodium bicarbonate) and vinegar (acetic acid). Students will investigate the signs a chemical reaction has occurred (gas production, change in temperature). Students will perform the lab in an open system so they can see the change of mass due to gas production. This lab is a lead into the topic of conservation of mass. After the lab is completed, the teacher should do a demonstration of the exothermic reaction Hydrogen peroxide and potassium iodide.
