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

    Demonstration: The Jumping Flame

    In this demonstration, students will observe that the vapor of an extinguished candle flame is ignitable.

  • Observations, Reaction Rate, Reaction Rate, Chemical Change | Elementary School, Middle School, High School

    Demonstration: Simple Kinetics

    In this demonstration, students will see that different food dyes react with bleach at different rates.

  • 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, Interdisciplinary, Molecular Formula, Conservation of Mass, Conservation of Matter, Molecular Structure, Balancing Equations, Reversible Reactions, Chemical Change, Matter, Photosynthesis, Monomer | Elementary School

    Lesson Plan: Plant Chemistry

    In this lesson, students will explore a simple, but key, biochemical reaction: photosynthesis.

  • Observations, Chemical Change, Inferences, Interdisciplinary, Chemical Change | Elementary School

    Lesson Plan: Strawberry DNA & CSI

    In this lesson, students will extract DNA from strawberries and analyze evidence to figure out who perpetrated a petty crime.

  • Solubility, Physical Change, Phase Changes, Reaction Rate, Solute & Solvent, Molecular Motion | Elementary School

    Lesson Plan: Particles in Motion

    In this lesson, students learn that particles that make up matter are in constant motion.

  • Chemical Change, Acid Base Reactions, Chemical Change, Exothermic & Endothermic | Elementary School

    Demonstration: Comparing Chemical Reactions

    In this demonstration, the teacher will perform two chemical reactions, one will be between acetic acid (vinegar) and sodium bicarbonate (baking soda) and the other will be between Alka-Seltzer and water. Both reactions will produce gas and will be conducted in a Ziploc bag, causing it to inflate. Students will observe the reactions and analyze the results in order to understand indicators of chemical change. Students will also determine that these are both endothermic reactions based on their observations.

  • Observations, Chemical Change, Acid, Interdisciplinary, Chemical Change, Acid Rain | Elementary School

    Lab: Chemical Weathering of Rocks

    In this lab, students will explore simulated reactions that contribute to chemical weathering of certain rocks as it appears in nature.  They will compare the effects of two different chemicals as it contacts various rock and mineral samples.

  • Pressure, Conservation of Matter | Elementary School

    Lab: Alka-Seltzer Rockets

    In this lab, students will conduct a chemical reaction that will be used to launch a rocket.

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

    Lab: My Pennies

    In this lab, students will investigate how an acidic, vinegar based solution can help to get “dirty” pennies clean. Students will observe chemical change and investigate real-world connections to this lab.

  • 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.
