Electricity is Everywhere!!! Lightning is a discharge of electricity in the atmosphere. Lightning bolts can travel at around 210,000 kph, while reaching nearly 30,000 °C in temperature.
Science Today • What is electricity? • Wall experiment • Understanding electricity • Atoms, electrons, and protons • How does it work?
What is Electricity? • What would happen without electricity? • Why is electricity important? • When you think about electricity, what do you think about?
Try This: Using Electricity IMAGINE
Balloon • What will happen to the balloon the first time? • What will happen to the balloon the second time? • How can you explain what you observed?
To understand what electricity is, you have to know more about atoms.
All About Atoms • Atoms are the building blocks that make up everything around us. • Each atom contain small particles that have an electric charge.
Atoms • Particles in atoms can have a negativeor positive charge. • Negative charge=electron (-) • Positive charged=proton (+)
Why is it important to know about these positive and negative particles?
Back to the Balloon… • Why did the balloon stick to the wall? • What happens to make an object attract another object? • Think about the different charges within each object
How Do Electric Charges Work? • We can change the balance of electric charges in an object so that the charges are unequal (unbalanced). • When this happens, the objected is charged with electricity!
How It Works • A positively charged wool is attracted to a negatively charged balloon. • Can protons attract protons? • Can electrons attract electrons?
