Classroom resources from our Acids and Bases professional development course for teachers
This collection is most valuable to those who have attended this course and wish to put into practice with their students some of the ideas and activities presented as part of that event. Please note that this list is not exhaustive; not all trainer activities have a corresponding classroom resource. In some circumstances there is variation between the training resource and classroom resource.
Create a ‘rainbow’ effect in a glass tube using universal indicator solution, hydrochloric acid and sodium hydroxide.
Drops of dilute acid and alkali are placed a few centimetres apart on a sheet of filter paper and allowed to spread out until they meet. A few drops of Universal indicator are then placed over the moist area of the filter paper and a band of colours showing the ...
The aim of this experiment is to help establish the idea that the pH of oxides vary. Students will discover that the soluble oxides of metals are alkaline and the oxides of non-metals are acidic.
Turn a mixture of methyl red indicator and soda water from red to yellow, and create a less acidic solution as the equilibria adjusts.
The aim of this experiment is to measure the maximum temperature reached during the reaction between hydrochloric acid and sodium hydroxide solution. The volumes that have reacted at the highest temperature, represent the ‘end point’ of the titration.
This resource is designed to provide strategies for dealing with some of the misconceptions that students have in the form of ready-to-use classroom resources.
This activity develops understanding of universal indicators and single indicators. The students build up their understanding by mixing two indicators. They also develop an awareness that the observed colour may be due to a mixture of colours.
Students add ammonia to a solution of copper(II) sulfate, observe the colour changes taking place and then reverse the reaction using sulfuric acid.
In this experiment you will be using microscale titration apparatus to complete an acid-base neutralisation. The aim is to calculate the exact concentration of sodium hydroxide solution.
Explore the basics of pH using this simulation. Add a variety of common solutions, modify the concentration and see the effects on pH.
Use this advanced pH simulator to view, modify, and visualise solutions with different ion ratios. Explore macroscopic, microscopic, and custom views.
