Slide 1 - Slide

Why do humans need energy?

Slide 2 - Mind map

Where do we get that energy from?

Slide 3 - Mind map

What are we going to learn today?
Today we will learn:
How plants transfer energy from the sun. 
Why this is important for all life on earth. 

Slide 4 - Slide

The sun
The sun is the most important source of energy for all life on earth.
Radiation reaches the earth --> plants convert that energy to food --> plants get eaten 

Slide 5 - Slide

Slide 6 - Slide

How can plants get food?
Plants convert energy from the sun into a substance they can use as food: food in the form of glucose
Glucose is a sugar that contains a lot of energy
This process is called photosynthesis
Photosynthesis is an example of metabolism. 

Slide 7 - Slide

How does photosynthesis take place?
A plant can't do photosynthesis on its own. It needs certain substances to let it take place. It need water which it gets out of the ground through the roots. It also needs carbondioxide, which is a gas. It absorbs the carbondioxide through the leaves. Of course it also needs sunlight

Slide 8 - Slide

What does a plant make with photosynthesis
When a plant has all those substances it can perform photosynthesis. During that, a plant makes glucose and oxygen. It stores glucose in differents parts of the plant, and it releases oxygen through the leaves.
