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

  • Molecular Formula, Stoichiometry | High School

    In this lab, students will measure how much carbon dioxide they exhale by reacting their exhaled breath with lime water (calcium hydroxide).

  • Combustion, Heat of Combustion | High School

    Lesson Plan: Redesigning a Car for the Environment

    Chemland’s city public transportation board has requested the class to help them determine the direction the city should move towards in reducing the carbon footprint. Students will be divided into groups and will come up with proposals of how to reduce the carbon footprint from carbon dioxide released from vehicles. The groups will represent different ways to reduce the carbon footprint via an alternative fuel source or a new technology. They will debate their findings to determine the direction that the city council should move towards to reduce the carbon footprint.

  • Classification of Reactions, Chemical Change | High School
