This activity is a lab designed for students to combust magnesium and use results to explain oxidation/reduction reactions.
In this electrochemistry activity, learners will explore two examples of electroplating. In Part 1, zinc from a galvanized nail (an iron nail which has been coated with zinc by dipping it in molten zinc) will be plated onto a copper penny. In Part 2, copper from a penny will be plated onto a nickel.
This activity is a lab investigation where students collect data concerning and endothermic and exothermic reaction.
This lab activity is designed to have students use their knowledge of balancing and identifying chemcial reactions and apply it in a fun and interesting way!
This is the first semester in a two-semester introductory course focused on current theories of structure and mechanism in organic chemistry, their historical development, and their basis in experimental observation. The course is open to freshmen with excellent preparation in chemistry and physics, and it aims to develop both taste for original science and intellectual skills necessary for creative research.
The overall goal of the authors with General Chemistry: Principles, Patterns, and Applications was to produce a text that introduces the students to the relevance and excitement of chemistry.Although much of first-year chemistry is taught as a service course, Bruce and Patricia feel there is no reason that the intrinsic excitement and potential of chemistry cannot be the focal point of the text and the course. So, they emphasize the positive aspects of chemistry and its relationship to studentsŐ lives, which requires bringing in applications early and often. In addition, the authors feel that many first year chemistry students have an enthusiasm for biologically and medically relevant topics, so they use an integrated approach in their text that includes explicit discussions of biological and environmental applications of chemistry.
In this unit designed for an integrated middle school science classroom, students investigate why athletes ice injuries. This leads students to wonder why actual bags of ice are used instead of the instant ice packs found in first aid kits. Students then investigate the chemical reaction occurring within an instant ice pack and work to develop a better design.
Anchoring Phenomenon: First aid care for musculoskeletal injuries using bags of ice instead of instant ice packs containing an endothermic chemical reaction.

During this activity students build a plastic pipette rocket. The first concept will to learn how igniting varying mixtures of hydrogen and oxygen will affect how far the rocket will fly. Second students will observe and manipulate variables to better understand the fundamental chemistry concepts: principles of combustion reactions, kinetics, stoichiometry, gas mixtures, rocketry, and different types of chemical reactions. Finally, students will assess their own understanding of these chemistry concepts by investigating how NASA scientists launch real rockets into space. One follow-up activity would be to investigate and collect data on a launching a heavier object at the school football field.
This lab gives students the opportunity to find the optimum mixture of hydrogen and oxygen as they react on a micro-scale.
In this activity, learners investigate the speed of chemical reactions with light sticks. Learners discover that reactions can be sped up or slowed down due to temperature changes.
This Introductory Chemistry textbook was developed by the Chemistry faculty at Montgomery College, and provided by Professor Patricia Takahara. The book is meant for students with very little or no background in chemistry. Concepts here are presented at a very basic level in order to provide the foundation for college-level general chemistry. This book is used in Introductory Chemistry, a non-credit, preparatory course at Montgomery College (Maryland).
This classroom lab allows students to develop skills of the scientific method while exploring the characteristics of enzymes.
This activity is an inquiry based lab where students determine 3 ways to change the rate of the chemical reaction between hydrochloric acid and alka-seltzer.
This activity is a lab investigation in which students observe the rate of generation of hydrogen gas from a reaction, and then modify the procedure to compare another variable affecting the rate of this reaction.
In this chemistry experiment, students will learn the fundamentals of copper plating (without using electricity) and if desired, extend the activity using different variables.
In this 8th grade science lesson, students prepare Whole Wheat Soda Bread with fresh churned butter and Chai. While the bread bakes in the oven, students experiment with chemical leaveners and observe the chemical reaction that causes the Whole Wheat Soda Bread to rise.
This investigation is a lab where students find out if mass is created or destroyed in a closed system. Students will balance the chemical equation to re-enforce their findings.
Chemical kinetics and buffers are two topics that are extremely difficult for students to understand. Combining the two topics will allow for a staggered, repetitive approach to teaching students to understand of how these two topics in chemistry actually work. Students will both qualitatively and quantitatively track the effect and enzyme has on a reaction, calculate the reaction rate and buffer capacity. Students will use a variety of lab techniques including calculations using Beers Law and spectrophotometry.
In this activity the temperature of a reaction is monitored for different concentrations of reactants.
Again- this is activity that will set the stage for enriching the understanding of the nature of molecular motion and the affect of temperature on its rate as the students allow crystals to diffuse toward each other in a petri dish and form a precipitate.
