Chemical Kinetics
Not all chemical reactions happen at the same rate because some, like explosions, occur quickly and some, like rusting, occur over time. Here, learners explore chemical reactions and their rates in the 16th lesson of 36. Through readings...

The Rate of Motion
How much time does it take to jump over three balloons? Pupils calculate the speed of tasks that require different motions. They determine motions for tasks such as walking, skipping, hopping, and jumping before creating a...
Curated OER
Slope, Vectors, and Wind Pressure
A hands-on instructional activity using the TI-CBR Motion Detector to provide information to graph and analyze. The class uses this information to calculate the slope of motion graphs and differentiate scalar and vector quantities. There...

Graham's Laws: Diffusion and Effusion of Gases
Students conduct a series of experiments to explore Graham's law. In this chemistry lesson, students differentiate effusion and diffusion. They perform calculations using Boyle's, Henry's, Charles' and Graham's Laws.
Curated OER
Differential Equations and Population Growth Lesson
Students calculate the size of the population at a given time, for a population that grows at a rate that is directly proportional to the number of members present in the population. They also calculate the time at which the population...

Vapor Pressure and Colligative Properties
Hate to vacuum, but enjoy using a vacuum pump? Explore a lesson that starts with a demonstration of boiling water at various temperatures by using a vacuum pump. Then scholars design their own experiments to measure vapor pressure and...

Chemical Equilibrium
Le Chatelier's interest in thermodynamics and building materials such as cement and plaster led to the Le Chatelier Principle in 1884. Activity 13 in a series of 36 extensively explores chemical equilibrium. Learners read about...

Studying Plant Development Through Metabolic Activity
A hands-on activity which allows students to learn about cellular respiration. This lesson plan contains a range of investigations testing the rates of cellular respiration to demonstrate the relationship between metabolic rates of...

Physical and Chemical Changes
Students examine the different changes in matter. In this chemical change lesson students determine the amount of reactant made in a reaction using the law of conservation.
Davidson College
Davidson College: Chemical Kinetics: Integrated Rate Laws
Explains the integrated rate laws for zero-, first-, and second-order reactions. Students then try a virtual stopped-flow experiment to find the rate law and the rate constant for a chemical reaction. Requires Java.
