Unit 3 Review

1. Science students often have to work in a laboratory. A lot of funny and ridiculous things happen there. Make up a ‘chain story’ to describe one of them.

Example: Peter got into a lot of trouble a couple of days ago. The trouble began

at his chemistry lab class.

Cue: While…………………

Student A: While the teacher was explaining the procedure of the experiment he was looking out of the window and daydreaming.

Cue: When …………………

Student B: When students started heating the substances he by mistake took the wrong test tube. He was nearly frightened to death to see the substance going out of the tube and splitting on the desk and his clothes. The desk got stains on it and his jeans got holes in them.

Cue: ……… before ………..

Student C: The teacher was very angry with him, though he was glad Peter had remembered to wear safety glasses before starting the experiment. Anyway, Peter’s lab work was a complete failure and now he has to …

Cue: …………………

Student D: ………………..

2. Use the word in blocks to form one word that fits in the gap in the sentence.

m) The product of two numbers is called ____________.	MULTIPLY

3. Divide into 5 teams. Each team completes mind maps for the words: experiment, accomplishment, development, laboratory and technology. Check your results as a class.

4. Explain the difference between the words.

to invent - to patent

experiment - observation

to be nominated for a prize - to be awarded a prize

technology - technique

award - reward

5. Read these sayings. Comment on the one you like most.

Ø “Our inventions mirror our secret wishes”. Lawrence George Durrell.

Ø “The guns and bombs, the rockets and the warships, all are symbols of

human failure”. Lyndon B. Johnson.

Ø “Accident is the name of the greatest of all inventors”. Mark Twain

Ø “No great discovery was ever made without a bold guess”. Sir Isaac Newton.

6. Work in pairs. Think of 3 words with each prefix from the list below.

1) tele-	3) mono-	8) semi-
2) aero-	4) bi-	9) multi-
3) photo-	5) super-	10) dec-
4) micro-	6) extra-	11) trans-
5) auto-	7) hydro-

7. See how quickly you can find the answer to this rather long sum.

Four add two, divide by three, subtract one, multiply by eight, take away four, times three, plus two, minus four, halved, equals what?

Each one teach one

Work on your own. Make a list of 10 international and ‘false friends’ words. Ask your fellow student to sort them out.

“There are no passengers on Spaceship Earth.

We are all crew.”
