    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.

  • 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.

  • Freezing Point, Phase Changes, Physical Change, Temperature | 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.

  • 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.

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.
