26 – 43 of 43 Classroom Resources

  • Density, Chemical Change, Density, Chemical Change | Elementary School, Middle School, High School

    Demonstration: Fire Extinguisher

    In this demonstration, students will observe a chemical reaction, and see how the product can be used to extinguish a fire.

  • Chemical Change, Pressure, Conservation of Matter, Reaction Rate, Acid Base Reactions, Chemical Change | Elementary School, Middle School

    Lab: Rocket Challenge

    In this lab, students will have the opportunity to construct a rocket, with the challenges of both designing it and preparing a chemical reaction for its “fuel” in order to propel the rocket over the furthest distance. Students will investigate available materials, quantities and ratios during allotted planning and testing phases. Student will record their plans, modifications and designs during the process. The lab will culminate with a competition amongst students to see whose rocket will travel the longest distance.

  • Elements, Identifying an Unknown, Conservation of Matter, Culminating Project, Chemical Change | Middle School

    Lab: Priestley Labs

    In this lab, students will identify an unknown gas based on experimental evidence.

  • Chemical Change, Precipitate, Balancing Equations, Chemical Change, Chemistry Basics, Solubility Rules | Middle School, High School

    Lab: Predicting Precipitates

    In this lab, students use solubility rules to predict which chemical reactions will produce precipitates.

  • Renewable Energy, Pressure, Conservation of Mass, Chemical Change, Volume | Middle School, High School

    Lab: Power That Stinks

    In this lab, students will experiment with creating and capturing biogas, and have an opportunity to look at how energy is created from waste. They will explore the differences between non-renewable and renewable energy sources.

  • Classification of Reactions, Chemical Change, Heat, Temperature, Exothermic & Endothermic | Middle School, High School

    Lab: Designing Exothermic and Endothermic Reactions

    In this lab, students will design and test an experiment for producing either an endothermic or an exothermic reaction. The goal of the lab is for students to successfully construct a reproducible procedure for a reaction that either releases or absorbs thermal energy, and that can be supported with data.

  • Observations, Chemical Change, Chemical Change | Middle School, High School

    Lab: Corrosion in Motion

    In this lab, students will expose metal samples to various solutions and observe the amount of corrosion of a period of time.

  • Observations, Chemical Change, Conservation of Mass, Chemical Change | Middle School, High School

    Lab: Conservation of Mass

    In this lab, students perform three simple experiments, recording the mass of a substance before and after a reaction. They then explain how the law of conservation of mass was not violated, even if the mass changed.

  • Observations, Chemical Change, Interdisciplinary, Physical Change, Reaction Rate, Reaction Rate, Chemical Change | Middle School

    Lab: Chemical Weathering in Geology

    In this lab, students will explore the differences between erosion, weathering and chemical weathering. They will complete a lab experiment that simulates chemical weathering on 4 different types of rocks. They will also learn how to use the Mohs Hardness Test to analyze the results.

  • Observations, Chemical Change, Chemical Change, Acid, Interdisciplinary, Physical Change, Chemical Change | Middle School

    Lab: Break It Down!

    In this lab, students will examine the physical and chemical changes that take place within a landfill by composting leftover fruits and vegetables from their lunches. They will also record pH and temperature measurements during the process.

  • Physical Properties, Chemical Change, Identifying an Unknown, Chemical Change, Scientific Method, Chemical Properties, Experimental Design | Middle School, High School

    Lab: As Easy as Pie

    In this lab, students will use chemical and physical properties to identify an unknown powder.

  • Observations, Chemical Change, Inferences, Reduction, Redox Reaction, Classification of Reactions, Chemical Change, Oxidation, Electron Transfer, Electrons, Ions | Middle School

    Lesson Plan: One Tube Reaction

    In this lesson, students will observe a chemical change involving oxidation and reduction.

  • Oxidation, Reduction, Redox Reaction, Chemical Change, Oxidation, Electron Transfer, Electrons | Middle School

    Lesson Plan: Old Rusty

    In this lesson, students will explore the concept of oxidation of metals by creating designs on fabric or paper using rusty objects.

  • Observations, Physical Properties, Chemical Change, Physical Change, Chemical Change, Temperature, Exothermic & Endothermic | Middle School, High School

    Lab: Observing a Chemical Reaction

    In this lab, students will practice making careful observations and measurements while witnessing a chemical change.

  • Observations, Chemical Change, Physical Change, Conservation of Mass, Conservation of Mass, Chemical Change, Measurements | Middle School, High School

    Lab: Mass & Change

    In this lab, students will use unified particle pictures of solid, liquid, and gas to explain the law of conservation of mass after carrying out various experiments.

  • Observations, Chemical Change, Chemical Change, Mixtures, Acids & Bases | Elementary School, Middle School, High School

    Demonstration: Inflating a Balloon with Chemistry

    In this demonstration, the teacher will perform a reaction between acetic acid (vinegar) and sodium bicarbonate (baking soda) in order to inflate a balloon and to introduce the concept of a chemical reaction to students. Students will observe the reaction, and identify indicators of chemical change as well as discuss the different types of matter that are involved.

  • Reaction Rate, Reaction Rate, Acid Base Reactions, Chemical Change | Middle School

    Lab: Bath Bomb Chemistry!

    In this lab, the students will work in cooperative groups to investigate how to make a scented, effervescent bath bomb and explore the chemistry needed to create them. Groups will test a variety of different variables in order to compare the reaction rate of each sample. Students will use the results to determine which variables are optimal for making and using bath bombs.

  • Polyatomic Ions, Chemical Change, Conservation of Mass, Precipitate, Conservation of Matter, Balancing Equations, Conservation of Mass, Chemical Change, Conservation of Matter | Middle School, High School

    Activity: Simulation Activity: Balancing Chemical Equations
