Classroom Resources: Reactions & Stoichiometry
26 – 34 of 34 Classroom Resources
-
Chemical Change, Pressure, Reaction Rate, Acid Base Reactions, Chemical Change, Conservation of Matter | 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.

Conservation of Matter, Chemical Change, Photosynthesis, Balancing Equations, Reversible Reactions, Molecular Formula, Molecular Structure, Conservation of Mass, Interdisciplinary, Matter, Elements, Monomer | Elementary School
Lesson Plan: Plant Chemistry
In this lesson, students will explore a simple, but key, biochemical reaction: photosynthesis.
-
Chemical Change, Observations, Inferences, Chemical Change, Interdisciplinary | 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, Solute & Solvent, Physical Change, Molecular Motion, Phase Changes, Reaction Rate | Elementary School
Lesson Plan: Particles in Motion
In this lesson, students learn that particles that make up matter are in constant motion.
-
Chemical Change, Exothermic & Endothermic, Acid Base Reactions, Chemical Change | 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.

Chemical Change, Chemical Change, Observations, Interdisciplinary, Acid, 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.
-
Conservation of Matter, Pressure | Elementary School
Lab: Alka-Seltzer Rockets
In this lab, students will conduct a chemical reaction that will be used to launch a rocket.
-
Chemical Change, Chemical Change, Observations, 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.
-
Chemical Change, Observations, Mixture, Acids & Bases, Chemical Change | 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.
