Electric animals
These small insects are under threat and need our help. They pollinate flowers and help us produce the food we need to survive.
Bees - Flowers often experience a change in electric charge after they are visited by an insect, so by sensing electric fields, bees can decide if to visit that flower or not
what is the type of electricity that doesn't flow
static electricity
Are electrons positively or negatively charged?
negatively
Why does the second circuit work? https://encrypted-tbn0.gstatic.com/images?q=tbn:ANd9GcQ6eOZMyxe2Irup_kdZgZmVSi20o444nbUTELdBT6nTi8Wl4Cme
Because the circuit is closed by a switch
who patented the incandescent light bulb? Thomas Edison or Alexander Graham Bell?
Thomas Edison
This species has eight legs and many people are scared of them although the majority are harmless.
spiders - they put a special kind of glue at their web that is attracted to charged particles (such as flying insects). The attraction is so strong that these lifeless webs will actually move forward to stick to flying prey. These webs are also attracted to airborne pollutants, meaning that spiders help make the air cleaner.
Electrical storms are a form of static electricity or an electrical current?
static electricity
What are the three basic parts of an atom?
electrons, protons and neutrons
What is the most common connector in a circuit?
the wire
Who invented the first dishwasher? Josephine Cochrane or Willis Carrier?
Josephine Cochrane
These monotremes have spines all over their bodies.
echidna - they use structures called electroreceptors in their snouts to find food. They can pick up on the electrical impulses given off by prey like insects and worms.
Say whether these materials are conductors or insulators: aluminium, water, plastic, copper, rubber, fabric, glass.
insulators - plastic, rubber, fabric, glass
conductors - aluminium, water, copper
What is at the centre of the atom? What is it made up of?
The nucleus, it is made up of protons and neutrons.
Which circuit will work? https://dryuc24b85zbr.cloudfront.net/tes/resources/6054133/image?width=500&height=500&version=1537949314281
Why?
The second because a circuit has to be like a circle, connected to a positive and negative
Did Marie Van Brittan Brown invent the mechanical television or the first CCTV home security system?
CCTV
These small reptiles are ubiquitous in Spain especially in hot weather. They are very good climbers because of their electric ability. Their tails fall off
lizards (geckos) - The gecko's Spider-Man abilities are due in part to the electrostatic forces on the gecko's feet pads. The difference in charge between his feet and the surface he's climbing help to keep him on the wall.
conductors allow electrons to move without much resistance but insulators do not allow electrons to flow easily.
What does it mean if an atom has a neutral charge? (in relation to electrons and protons)
When there is an equal number of electrons and protons the atom has a neutral charge.
Give two examples of a load in an electronic circuit
Examples are everywhere including light bulb, washing machine, television, computer, hand dryer, iron etc - anything that converts electricity into another light form.
What was invented first, the light bulb or the telephone?
The telephone
These long thin fish live in the Amazon in rivers and ponds. They shock their prey before eating them.
Electric eels - They have electrogenic cells that they use to stun prey, defend against predators and even communicate with other eels. With a strong enough shock to cause heart failure
Name a naturally occurring electronic spark and the noise it makes
lightning and the noise it makes is thunder
What is electricity?
it is energy that flows everywhere around us
name the four basic parts of a circuit and an example for three of these parts
power source - battery
conductor - wire
switch
load - light bulb
Who invented the lightbulb? Warren de La Rue or Joseph Swan?
