Hands-on activity video guides

We've created 5 hands-on activity videos to demonstrate some of the activities from our resources packs. The videos and the accompanying written resources and available to view and download below. Please contact [email protected] if you have any questions about running your own activities and events. 

Blossom the Cow

This activity uses a simple acid-alkali reaction with indicators to demonstrate how vaccinations work and simulates how Dr Edward Jenner used cowpox  pus from the hand of a milkmaid to inoculate an eight-year old boy, James Phipps. This was the first vaccination against smallpox. 

The written instructions can be found on pages 9–11 of the ‘Pathology For Life’ document below.

Clots of Blood

If our blood didn’t clot, every time we cut ourselves we would keep bleeding forever. This activity shows the different consistencies of ‘fake’ blood: fresh and clotted.

The written instructions for this video can be found in the 'Blood Clotting’ document below. We also have a range of other related available on our 'Blood and Bugs' resources page.  


Microscopes are vital in diagnosis. Pathologists look at tissue samples under microscopes to magnify cells and find any abnormalities. Anything that looks different can hold clues as to what the patient might be suffering from, and what the treatment needs to be. The first video demonstrates how to make your own simple light microscope, while the second video shows how we can also use a smart phone to create a digital microscope.

The accompanying written resources can be found on pages 24–26 of the ‘Pathology For Life’ document below. 

Tinkle Testing

Pathologists can diagnose disease and monitor our health by testing our urine. In this activity, you can create at a set of ‘fake’ patient urine samples and test them to make a diagnosis. 


The written instruction can be found in the Scout Pack Resource, which will be added to the written resources listed below.
