    Demonstration: Rates of Reactions

    In this series of demonstrations, students will be introduced to factors that affect the rates of chemical reactions.

  • Chemical Change, Exothermic & Endothermic | Elementary School, Middle School

    Demonstration: Giant Toothpaste

    In this demonstration, students will identify factors that indicate a chemical change has occurred while observing the production of giant toothpaste.

  • Observations, Catalysts, Classification of Reactions, Chemical Change | Middle School, High School

    Demonstration: Catalyst in Motion

    This demonstration allows students to visualize how a catalyst can impact a chemical reaction. Students will also identify the products of a decomposition reaction, as well as determine if the reaction was endothermic or exothermic based on their observations.

  • Activity Series, Classification of Reactions, Chemical Change | High School

    Lab: Investigating the Activity Series of Metals

    In this lab, students will create an activity series of metals and predict whether or not single replacement reactions are likely to occur.

  • Stoichiometry, Mole Concept, Dimensional Analysis | High School

    Lesson Plan: Map It Out!

    In this lesson, students should be able to use a graphic organizer to help them solve stoichiometry problems. This lesson utilizes the Cornell note format.

  • Balancing Equations, Combustion, Stoichiometry | High School

    Activity: Calculating Your Carbon Footprint

    In this lesson, students apply their knowledge of writing and balancing chemical equations and stoichiometry calculations to estimate their carbon footprint. Students are also asked to reflect on their carbon footprint and what it means.

  • Concentration, Reversible Reactions, Le Châtelier's Principle | High School

    Lab: Le Chatelier’s Soda

    In this lab, students will observe how the equilibrium of a chemical reaction is affected when a change in pressure, temperature, and concentration is applied to the system.

  • Renewable Energy, Interdisciplinary, Conservation of Matter, Matter | Elementary School

    Lab: Reuse, Reduce and Recycle!

    In this lab students will explore ways to conserve natural resources. They will then have the opportunity to create their own recycled paper that can be used in the classroom.

  • Renewable Energy, Phase Changes, Photosynthesis | Elementary School, Middle School

    Lab: Mini Terrarium

    In this lab, students will learn that even the smallest spaces can have their own climate. They will create a miniature sized terrarium and will observe how sunlight enters in order to warm the air, and in turn heat the soil and seeds. Condensation will build up in the container and the students can observe the water cycle in action, as well as the growth of the seeds over time.

  • Molecular Structure , Subatomic Particles, Photosynthesis | Middle School

    Lesson Plan: Carbon, Carbon Everywhere

    In this lesson, students will learn about how Carbon cycles through Earth’s systems and its importance for life on Earth.

  • Acid Base Reactions, Stoichiometry, Percent Composition, Titrations, Indicators | High School

    Lab: The Egg-straordinary Issue

    In this lab students will determine the percent composition of calcium carbonate contained in an eggshell by using a back titration in order to address a farmer’s concerns about his hen’s fragile eggs. Two versions of the student lab are included, a scripted version, and an inquiry version.

  • Observations, Chemical Change, Physical Change, Chemical Change | Elementary School

    Demonstration: Make a Cake!

    In this demonstration, students will learn about chemical reactions by observing the differences when 4 small cakes are baked. Each recipe will differ slightly in that one important ingredient will be left out in 3 of the 4 mixtures. Students will observe and discuss what happens when things are missing or left out of a mixture and how that effects the chemical reaction.

  • Concentration, Solute & Solvent, Chemical Change | Elementary School, Middle School

    Demonstration: Soft Eggs

    In this demonstration, students will first observe a reaction between vinegar (acetic acid) and an egg shell (calcium carbonate) to produce a naked egg. Using these eggs, student will analyze how certain substances can move through a membrane and also determine if the membrane is affected.

  • Balancing Equations, Conservation of Mass | Middle School, High School

    Activity: Balancing Legos

    In this activity students use Legos to model the reactants and products in a chemical reaction. They use these “atoms” and “molecules” to balance the chemical reaction in order to demonstrate the law of conservation of matter.

  • Chemical Change, Chemical Change | Elementary School

    Lab: Teeth Eggsperiment!

    In this lab students will observe and analyze how different drinks can stain an egg’s shell. They will then associate the results with how these drinks can stain their teeth.

  • Mixtures, Reaction Rate, Chemical Change | Elementary School
