Reaction Rate, Reaction Rate | Middle School, High School
Simulation: Reaction Rates
In the May 2018 simulation, students investigate several factors that can affect the initial rate of a chemical reaction, including concentration, temperature, surface area of the reactants, and addition of a catalyst.

Reaction Rate, Reaction Rate | Middle School, High School
Activity: Simulation Activity: Investigating Reaction Rates
In this simulation, students will have the opportunity to investigate several factors that can affect the initial rate of a chemical reaction. Students will have the opportunity to manipulate several variables including concentration, temperature, or surface area of the reactants as well as the addition of a catalyst during the simulation. These reaction rates will be compared to a controlled reaction. Students will interpret a simplified qualitative representation of the reaction as well as analyze corresponding data organized on a graph.

Reaction Rate, Chemical Change, Reaction Rate, Observations | Middle School, Elementary School, High School
Demonstration: Simple Kinetics
In this demonstration, students will see that different food dyes react with bleach at different rates.

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.

Lab: Plop, Fizz: How to Affect the Rate of a Chemical Reaction
In this lesson, students will react Alka-Seltzer tablets with water. By varying the temperature of the water, particle size of the Alka-Seltzer, and concentration of the Alka-Seltzer they can see the effect on the rate and strength of the chemical reaction.

Lab: Chemical Weathering in Geology
In this lab, students will explore the differences between erosion, weathering and chemical weathering. They will complete a lab experiment that simulates chemical weathering on 4 different types of rocks. They will also learn how to use the Mohs Hardness Test to analyze the results.

Lab: Bath Bomb Chemistry!
In this lab, the students will work in cooperative groups to investigate how to make a scented, effervescent bath bomb and explore the chemistry needed to create them. Groups will test a variety of different variables in order to compare the reaction rate of each sample. Students will use the results to determine which variables are optimal for making and using bath bombs.
