Free virtual experiment on the pH scale!

Try our free virtual experiment to show your class how they can use universal indicator to determine pH.

 This interactive animation demonstrates how they can test various household items, from vinegar to toothpaste, and compares the colour each produces to the pH scale.

A summary chart then enables your class to compare the results, and determine what the most acidic and alkali substances were.

Free interactive presentation on the properties of waves!

Download our free GCSE Physics presentation to demonstrate the key principles of the wavelength, frequency and speed of waves.

This presentation contains engaging virtual experiments, including an interactive oscilloscope activity and a key practical requirement using a ripple tank. This practical animation will also help develop your students working scientifically skills as a helpful recap slide details potential sources of error for the experiment.

A final multiple choice quiz will also test your student’s mathematical understanding with an interactive wave speed equation activity.


Free KS3 interactive on static charge!

Show your students how a balloon can demonstrate static charge with our free animation!

This fun visual interactive investigates how different items are affected by contact with a charged balloon.

First, fully charge the balloon by rubbing it on a woolly jumper. Then explore how a wall, a cat, scraps of paper, and running water are all affected by the charged balloon. Use the zoom function to show your students exactly how the negatively-charged balloon repels the negative charges of the item and is attracted to its positive charges.

This interactive is an excellent starter before students plan their own investigation into static charge!


Free KS4 presentation on carboxylic acids!

Download the free presentation on carboxylic acids
