How to work with Required Practicals: Part 3 (AQA Combined Physics Paper 1 2022)

Oriental hornet

While you are revising for the Required Practicals for Physics, why not take a break – and learn some fun facts about electricity.

Lightning, the release of electric charge in the atmosphere, travels at around 220,000,000 mph! Also it can reach temperatures as high as 54,000 °F. The lightning rod, which was invented by Benjamin Franklin in the 18th century, protects buildings in case they are struck by lightning. The rod carries the lightning charge to the ground.

Electric eels generate electric shocks of up to 600 Volts. Having no teeth, they use strong bursts of electricity to stun prey, or deter predators. Three specialised electric organs make up about 80% of the body. The organs all contain thousands of specialised cells known as electrocytes. These produce a weak electrical discharge, and are similar to tiny batteries. When feeling threatened, or when attacking prey, the cells will all discharge simultaneously!

There are also other animals which have the ability to communicate, defend themselves, or find food via electricity. This is common in water species, however , can also occur in land animals. Apparently the oriental hornet is very fond of intense sunlight. When scientists investigated, they discovered “solar panels” on the body , which were converting sunlight into electricity!! Why they do this is still a mystery!

Try our new guide “How to work with Required Practicals: Part 3”. It focuses on the Physics practicals needed for Combined Science Paper 1 (AQA) in 2022.
It includes:

 Specific Heat Capacity,

I-V Characteristics

You will find a brief description of what you need to know about each practical, and key questions you may be asked. As always there are questions to try, and answers to check your understanding.
