Science - Static Electricity
So covid has hit New Zealand again and we are in lockdown. For science, we are learning about static electricity and how it works. In this, we covered: Atoms, electrons, protons, and neutrons.
What are the 3 particles that make up everything? Which ones have positive and negative charges?
The three particles are:
- Protons
- Neutrons
- Electrons
Objects want to be "electrically neutral". What does this mean?
"Electrically neutral" means when protons and electrons hit and create a spark then things get Neutralised.
When you rub two insulators you can get a static shock, so what is an insulator and a conductor?
When two insulators rub together they become electrically charged. Electrons are negative charged which may be 'rubbed off' one material and then on another. Then the materials that gain electrons become negatively charged, and then the material that loses electrons is left with a positive charge.
Insulator - any of various substances that block or retard the flow of electrical or thermal currents
Conductor - Conductors are materials that permit electrons to flow freely from particle to particle
What is an example of static electricity?
An example of static electricty is lighting - An electric charge builds up as part of a "positive lightning strike.
Or another example is a ballon - the rubbing creates a negative charge that is carried by electrons

To support my learning I ask you to comment as follows:
1. Something positive - something you like about what I have shared.
2. Thoughtful - A sentence to let us know you actually read/watched or listened to what I had to say
3. Something helpful - how have you connected with my learning? Give me some ideas for next time or ask me a question.
