Everything is in classroom

Slide 1 - Tekstslide

What was renewable energy?
A
New types of energy
B
It does not run out, it renews itself
C
energy that consists of waves
D
It runs out, so we won’t be able to use it forever

Slide 2 - Quizvraag

What does the 'law of conservation of energy' mean?
A
energy can not convert from one form to another
B
Energy has to uphold the law
C
Energy is never lost
D
Energy is lost when converted

Slide 3 - Quizvraag

Nuclear energy is
A
sustainable
B
Renewable
C
sustainable and renewable
D
Not sustainable nor renewable

Slide 4 - Quizvraag

heat transfer via direct contact.
heat transfer via air or water.
heat transfer via light/ electromagnetic radiation
convection
conduction
Radiation

Slide 5 - Sleepvraag

learning goals
explain why a vegetarian diet is more sustainable
explain how pesticides can accumulate in the food chain and kill predators
explain how different kinds of pollution can lead to long term problems
Explain what the greenhouse effect is and how extra gasses can enhance this and cause global warming
use the three R's to identify ways to live more sustainable

Slide 6 - Tekstslide

What does sustainable mean
A
bad for the environment
B
it kills living things
C
better for the environment
D
using pesticides to help the environment

Slide 7 - Quizvraag

Food choices
All of the energy of our food comes from the sun

A lot of that energy is 'lost' 

By eating less (or no) animals we 'lose' less energy

Slide 8 - Tekstslide

Slide 9 - Tekstslide

food choices
Other things that do NOT help the environment
1. Pesticides (to kill insects on crops)
2. A lot of transport (fuel usage)
3. Use of antibiotics for animals

All this builds up in the food chain before it gets to us
This is called accumulation

Slide 10 - Tekstslide

Pollution
Our modern way of life causes a lot of pollution

A lot of materials like plastic are NOT biodegradable

Eventually these plastics will get smaller and get into our food chain

Slide 11 - Tekstslide

Pollution _________________________.
A
is harmful materials put into the environment
B
found in air, water, and land
C
effects plants, animals, and people
D
All of the above

Slide 12 - Quizvraag

What is air pollution?

A
Any harmful substance that builds up in the air
B
pollen, dust, gases
C
chemicals in the water
D
industrial pollution

Slide 13 - Quizvraag

greenhouse effect
The effect is important for earth 

It keeps the earth warm

But to much is not OK

Slide 14 - Tekstslide

Greenhouse effect

Slide 15 - Tekstslide

greenhouse effect
greenhouse gasses such as carbon dioxide ( CO2 ) and methane ( CH4 )
 cause a bigger greenhouse effects

Heat (radiation) can't leave the atmosphere 

Earth heats up (global warming)

Enhanced greenhouse effect


Slide 16 - Tekstslide

The greenhouse effect is a natural phenomena
A
True
B
False

Slide 17 - Quizvraag

What is the greenhouse effect?
A
Global warming
B
Climate change
C
Gasses re-radiate heat back to earth
D
Air pollution that heats the earth

Slide 18 - Quizvraag

Energy
Power
Time
Voltage
current
I
P
U
E
t

Slide 19 - Sleepvraag

Place the correct symbol behind the electrical components
Battery
Wire
Switch
Light bulb
LED
Mains socket

Slide 20 - Sleepvraag

voltage is the same for all components
current is the same throughout circuit
Series
Parallel
Still works if one lamp is broken
If you connect batteries this way, you can add their voltages

Slide 21 - Sleepvraag

Sustainable living
How can we live more sustainable

The three R's:
Reduce
Reuse
Recycle

Slide 22 - Tekstslide

seperate your trash so that certain materials can be used again
 use things more than once
lowering the amount of energy and resources you use
Reduce
Reuse
recycle

Slide 23 - Sleepvraag

What is a catalyst?
A
something that makes substances burn
B
something that prevents materials to burn
C
something that increases the ignition energy
D
something that lowers the ignition energy

Slide 24 - Quizvraag

A
360 V
B
12 V
C
230 V
D
1500 V

B
Nucleon
C
Muon
D
Electron

Slide 26 - Quizvraag

The formula is P = U x I
Witch of these is also correct?
A
U = I / P
B
U = P x I
C
U = P / I
D
U = P + I
