Biology
Pea soup
You can get ciguatera poisoning from the waters around the Caribbean.
Have you ever had ciguatera poisoning?
How does the toxin enter the human body?
Why is ciguatera dangerous?
Toxins produced by living organisms also cause problems in the Netherlands.
This module focuses on the effects of biotic and abiotic factors on ecosystems.
We also look at food chains in different ecosystems.
Good luck!

Chemistry
Equilibrium
This module is about equilibria.
On the basis of chemistry experiments you will use reasoning to ascertain whether a chemical reaction is in equilibrium. You will also learn how the position of the equilibrium can be influenced.
- How are acids and bases represented in the clip?
- Give two examples of an acid and two of a base.
- What happens when acids and bases are combined?
- What is the difference between a strong acid and a weak one?
- What is pH?
- Give two examples of why the pH is important in the human body.
- How is the pH kept constant in the body?

Green Chemistry
In the past ten to twenty years there has been a new development in the chemical industry: Green Chemistry.
Green Chemistry is a fundamental concept for making chemicals as sustainably as possible.
The central idea is that as few harmful materials as possible should be produced and used in chemical processes.
In this module you will make a recommendation. You will give advice on the best way for a nearby chemical plant to make a particular product.The product can be prepared using two production routes. Which way is ‘the greenest’?

How can we eat healthily
Eating. We do it every day.
Some days a bit more healthily than others.
What substances are actually in all that food that we consume?
And what does our body need those substances for?
What happens in our body when we consume too much or too little of those substances?
Are some low-fat margarines really better for the cardiovascular system? Are we doing our intestines a favour by eating a tub of yoghurt containing probiotics every day? And what about all those ‘light’ products that are on the market today? In short: how can we eat healthily?
