Chapter 3 overview

Chapter 3 — Energy

Step 1: Go over chapter 3, Flip through the pages. Look at what they cover.

Step 2: Write down the title of each section and underneath it write down what this section covers. This gives you an overview of the chapter

Step 3: What new concepts can you find in this chapter?

Step 4: 

• What new formula's can you find in this chapter? 
  
• Which formula's reoccur from previous chapters?

The paragraphs we will cover

•  Energy sources
• Heating
• Insulation
• efficiency

Formula's we will learn to use

Calculating heat

Efficiency

Q=c⋅m⋅ΔT

Q=U⋅A⋅ΔT

η=​E​tot​​​​E​used​​​​⋅100

η=​P​tot​​​​P​used​​​​⋅100

E=P⋅t

P=U⋅I

There will be a practical this period

• This will be spread out over two lessons.
  
• You will get a summative grade for it.
  

Section 1 — Energy sources

Energy discussion

What is energy?

• The ability to do work.
  
• A resource that you need to do the things you have and want to do.
  

Discussion

Discuss the following points in pairs of two

• A) What are examples of things you need energy for?
  
• B) What are examples of things you need energy for at home?
  
• C) What are examples of things a country need energy for?
  
• D) What energy sources does the Netherlands use?
  
• E)What is the correlation between how advanced a society is and how much energy they use?
• F) What is the benefit of being able to use a lot of energy?
• G) What is the downside of using energy?
