  • Observations, Molecular Motion, Heat, Specific Heat, Temperature | Middle School, High 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.

  • Observations, Inferences, Molecular Motion, Temperature | Middle School, High School

    Demonstration: What is Temperature?

    In this demonstration, students will observe food dye mixing with water at different temperatures.

  • Observations, Density, Physical Properties, Introduction, Mixtures | Elementary School

    Lesson Plan: What is Density

    In this two-part lesson, students will learn about density through a teacher-led demonstration and a hands-on activity. The demonstration will give students the opportunity to observe the formation of a density tower made from common drinks. Students will then create their own density tower using simple ingredients, and then further investigate differences in density when solid objects are added to the tower.

  • Observations, Physical Properties, Introduction, Elements, History, Periodic Table, Chemical Properties | High School

    Lesson Plan: What is Chemistry?

    In this lesson, students watch a video narrated by Bill Nye, and then complete a SOMA cube to enhance their perspective in the process of discovery.

  • Observations, Chemical Change, Conservation of Mass, Chemical Change, Heat, Temperature, Exothermic & Endothermic | Middle School, High 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.

  • Observations, Chemical Change, Balancing Equations, Classification of Reactions, Chemical Change | High School

    Lab: It's Time to React

    In this lab, students will conduct four chemical reactions and analyze each for indicators of a chemical reaction. Based on their observations students will write a balanced chemical equation for each reaction as well as identify the reaction type for each reaction.

  • Observations, Introduction, Elements, History, Periodic Table, Atoms, Model of the Atom, Culminating Project, Matter | High School, Middle School

    Activity: Is a Picture Worth 1000 Words?

    In this activity, students will learn about early chemistry discoveries through a textbook reading as well as from a cartoon.

  • Observations, Physical Properties, Mixtures, Interdisciplinary, History, Chemical Properties | High School, Middle School

    Lab: Top Secret

    In this lab, students will learn about the history of invisible ink and will have the opportunity to compare two types of homemade invisible ink recipes.

  • Observations, Chemical Change, Reaction Rate, Reaction Rate, Catalysts, Chemical Change | Elementary School

    Lab: To What DEGREE Does it Matter

    In this lab the students will explore how factors such as temperature may influence chemical reactions. Students will use citric acid and sodium bicarbonate (Alka-Seltzer) and a catalyst (water) to induce a reaction at varying degrees. Observations will be made of the rate at which the reactions take place under these varying conditions. The students will make predictions of how the temperature of the water will affect the chemical reaction. They will use a stop watch to time the reaction between the Alka-Seltzer and the varying temperatures of water and graph their observations for analysis, they will compare data to deduce whether temperature has any influence during a chemical reaction.

  • Observations, Naming Compounds | High School

    Activity: Ionic Compound Identification

    In this activity, students will practice naming and writing formulas of ionic compounds by looking at examples.

  • Observations, Density, Chemical Change, Density, Combustion, Chemical Change | Middle School, Elementary School

    Demonstration: Investigating Gas Density

    In this demonstration, students will observe a reaction between baking soda and vinegar in the presence of a burning candle. The initial environment has plenty of oxygen present in order to sustain the candle’s flame; however the reaction will produce carbon dioxide which will cause the lit candle to extinguish. Students will analyze the outcome and compare the presence of the gases in the container and make determinations about the densities of each.

  • Observations, Chemical Change, Interdisciplinary, Acid Base Reactions, Classification of Reactions, Chemical Change, Acid Rain, pH | High School

    Activity: Investigating Acid Rain

    In this activity, students will investigate the chemistry of acid rain through web based research. Students will also have the opportunity to observe the reaction between a common acid and a material in a week long simulation and relate their findings to the effects of acid rain.

  • Observations, Chemical Change, Inferences, Stoichiometry, Conservation of Mass, Limiting Reactant, Chemical Change, Exothermic & Endothermic | High School

    Demonstration: Introducing Limiting Reactants

    In this demonstration, the teacher will perform a series of reactions between acetic acid--vinegar-- and varying amounts of sodium bicarbonate --baking soda--in order to inflate several Ziploc bags. Students will observe the reactions and analyze the quantities of reactants used as well as the results in order to understand the concept of limiting reactants. Students will also determine if the reaction is an endothermic or exothermic process based on their observations.
