Collaborating chemistry pupils observe that temperatrue increases the movement of dye throughout water, stirring increases the dissolving rate of sugar cubes, and concentration of solutions increases the chemical reaction rates. These...

Introduce high schoolers to chemical reactions with this series of activities. In a little over an hour, scientists observe four gas-producing reactions: the combination of hydrochloric acid and sodium hydroxide, placing pasta in...

Students explore critical thinking by conducting a reaction time experiment. For this human brain lesson, students utilize a timed Internet worksheet activity to research how fast their brain works when answering questions. Students...

A total of five experiments lead chemistry pros to understand the difference between physical and chemical change. They also experiment with exothermic reaction factors that affect rate of reaction. The procedures are not written in the...

Young scholars record reaction time data and calculate minimum, maximum, mean, median, and mode. They participate in a class reaction time activity, observe and conduct an online experiment, and discuss and analyze the activity results.

Third graders review important vocabulary to explain measures of central tendency and reaction time. In pairs, they measure reaction time of dropping and catching a ruler. Data is collected after repeated catches and information is...

If your pupils think a catalyst is a list of their cats, then this might be the lesson for you! Young chemists study the effect of temperature, catalysts, concentration, and particle size on reaction rates during four different...

Young scholars devise an experiment to test the rate of decomposition of hydrogen peroxide. In this rate of reactions lesson plan, students use the given information in the lab to write a procedure that will allow them to find the rate...

Students recognize different consumer products, found in and around the home, that have reactive or denaturing properties when used together. They explore chemical and physical properties of each product by identifying chemical formulas...

Students investigate the reaction rate of iodine and soluble starch. In this rates of chemical reactions lesson plan, students study the effects of varying concentrations of reactants and varying temperatures of reactants on the reaction...

Students participate in a hands-on activity in which they observe the effect of temperature on the rate of chemical reactions. Using Alka Seltzer tablets in different temperatures of water, they record the amount of time it takes each...

Students create predictions on what they believe happen to reaction rates when temperature is raised. They use hot, cold, and room temperature water for this experiment and observe the differences. They graph their observations and...

Students investigate how varying the concentrations, volumes, and other factors affects reaction rates. Students design and conduct investigations to obtain data used to create graphs of an uncatalyzed reaction vs. a catalyzed reaction....

Students listen to a lecture on the collision theory. They discuss the reactant and product changes during a chemical reaction. Students are taught the factors affecting reaction rates. They complete a lab on entropy, heat and free...

Learners study reaction rates, what determines how fast a reaction happens and how the chemical changes occur.  In this reactions lesson students complete a lab where they use Alka-Seltzer to observe reaction rate and create a graph...

In this temperature and reaction rate worksheet, students complete a graphic organizer to show the relationship between temperature increasing and the rate of a reaction and temperature decreasing and the rate of a reaction.

Students complete an experiment with Alka-Seltzer and reaction rates. They control the rate in which gases are allowed to escape. They test their predictions and observe what happens during the experiment.

Putting glow sticks in the freezer makes them last longer, but why is that? Lesson focuses on how temperature impacts the rate of a chemical reaction. It begins with a teacher demonstration, then scholars design their own experiments...

Catch me if you can. Scholars collect data on reaction time by catching a falling ruler or by using an Internet app. They determine the median of the data, create graphs, and analyze the results. They also compare their data to the rest...

Students explore how skills can improve through practice and awareness, using a reaction-time activity that focuses on both visual and auditory responsiveness.

Students investigate their reaction times for grabbing a dropped ruler after discussing reactions times to other events such as moving your foot from the gas pedal to the brake. They drop the ruler from a sent height and record the time...

Scholars learn about kinetics and buffers as they use qualitative and quantitative methods to understand enzyme rates and buffer capacity. The application of Beer's Law and spectrophotometry solidifies pupils' knowledge in the first of...

Students investigate the rate of a chemical reaction. In this rate of reactions lesson plan, students use an electronic balance to measure the change in mass of a chemical reaction between hydrochloric acid and calcium carbonate. They...

As an introduction to the skills required for and responsibilities of driving, pre-teens and teens engage in a series of activities, chart their response times, and analyze how variables effect these reaction times. Class...
