Science - Static Electricity

 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

The Protons are positively charged, the  Electrons are Negatively charged, and the Neutrons are Neutralise when both the charges are combined.

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

Wananga Activity - The seven wonders in the world

Wananga Activity!

Kia ora everyone, welcome back to another blog post for this week. For today's second blog post I am posting about the seven wonders in the world. I have picked this task out of our activity board that our teacher made for us, I picked this task because I don't know much about the seven wonders in the world, and also I just sounded interesting and fun to research about.  Do you know what the seven wonders of the world are? if you don't this is your lucky day to learn about them. 

What are the seven wonders in the world?

1. Taj Mahal - Agra, India
2. Colosseum - Rome, Italy
3. Machu Picchu - Peru
4. Christ the Redeemer - Rio, Brazil
5. Chichen Itza - Yucatan, Mexico
6. Petra - Wadi Musa, Jordan
7. Great Wall of China - Beijing, China

What are they?

Taj Mahal - an ivory-white marble mausoleum, was built for Shah Jahan's favorite wife, Mumtaz Mahal.

Colosseum - a large amphitheater that hosted events like gladiatorial games, It was built during the reign of the Flavian emperors as a gift to the Roman people.

Machu Picchu - a 7,000-foot tall mountain in the Andes Mountain, the most visited location in Peru.

Christ the Redeemer - symbolic protector of people, provides protection for the soul.

Chichen Itza - This was a large Mayan city established in the fifth century B.C. in central Yucan, was a very important religious center.

Petra - An ancient city that lies in present-day Jordan and dates back to the fourth century B.C.

Great Wall of China - An ancient series of fortifications totaling more than 13,000 miles in length.
