The Large Hadron Collider (LHC) is the world’s largest and most powerful particle accelerator. It first started up on 10 September 2008, and remains the latest addition to CERN's accelerator complex. The LHC consists of a 27-kilometre ring of superconducting magnets with a number of accelerating structures to boost the energy of the particles along the way... Continue reading at CERN.

B. Say whether the following statements are true or false by clicking on the correct button first. Then, write your corrections to the false ones in the box.
1. Hundreds of engineers, scientists and mathematicians have designed and built the LHC.
2. The purpose of the LHC is to study matter.
3. The beams circulated in the LHC are roughly the shape of spaghetti.
4. The beams move at a speed greater than the speed of light.
5. Protons will not collide most of the time because of all the empty space matter is made of.
6. 800 million collisions a day are generated by the LHC.
7. Magnets are used to turn hair into spaghetti.
8. Particles are so elusive, observation is extremely time sensitive.
9. Atlas, Alice, LHC-B and CMS are experiments at collision points.
10. The famous Higgs Boson was spotted in Atlas and CMS in 2015.

In groups of 3 or 4, imagine you have created a device which helps you control a special feature of physics in a new way (light, space, gravity, time, temperature, sound etc.). Each member of the group must individually come up with their own innovation.
Examples: a device to nullify sound, clothes that help regulate temperature, a mini-black hole to remove radioactive waste etc.
a. Describe your discovery to the Science Committee (played by the 2 or 3 other students in the group) and be enthusiastic about all its positive aspects.
b. The Science Committee will then have to find some potential negative aspects, dangers or misuses of your discovery.
c. Together, decide if you should make the discovery public and what you could do to limit the risks.
If you are at home, use this opportunity to record yourself using your phone/tablet/computer. If you feel confident about your performance, you can send it to your teacher for assessment.

Adjectives are words that describe or modify another person or thing in the sentence, i.e. they refer to qualities.
Adjectives derived from verbs are very common in English. They can derive from the present participle (-ing) or from the past participle (-ed).
-ing adjectives are "active", which means they cause the actions. Conversely, -ed adjectives are "passive", so they rather show the effect of the action.
Look at the diagram for some examples of -ing and -ed adjectives.
D. Read the following sentences and click on the correct -ing/-ed adjectives.
1. The film was quite exciting / excited. I enjoyed it.
2. Are you interesting / interested in football?
3. I had never expected to get the job. I was really amazing / amazed when I was offered it.
4. I didn't think it was funny. I wasn't amusing / amused.
5. He's one of the most boring / bored people I've ever met... he keeps talking and never says anything interesting / interested.
We may think that adjective order is free in English, but that's far from the truth. In fact, adjectives follow a relatively fixed organisation in the sentence.
The following diagram shows how to organise adjectives in a sentence:
| Determiner | Adjectives | Noun | |||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|
| Opinion | Size, height | Shape, weight, length | Condition, state | Age | Colour | Pattern, design | Origin, nationality | Material | Purpose | ||
| An, one/two/three, the, my, your, his, her, this, those, some... | lovely, delicious, cool, nice, shitty | big, huge, small, tine, tall, short | round, square, long, fat, thin | clean, dirty, wet, dry, rich, hungry | young, old, new, antique | blue, green, reddish, purply | spotted, checked, flowery, zigzag | American, British, Asian, Oriental | gold, woollen, paper, synthetic | riding, gardening, shopping | house, person, idea |
| An | ugly | small | thin | dirty | odd | red | striped | Italian | cotton | sleeping | bag |
| Determiner | Adjectives | Noun | |||||||||
Note: Don't worry, you will not come across sequences of adjectives this long.
It may seem confusing at first, but this structure is already present in your brain. You will be able to put adjectives into the right order more or less naturally. Just follow your intuition!
And REMEMBER! Your opinion always goes first.
E. In the following challenge, you will find ten jumbled (= disorganised) sentences. You have 3 minutes to unjumble them and place the adjectives in the right order. [Level: EASY]
