Introduction

During the course of your study and probably in your future as well, you will be asked to describe an experiment. In this unit we will focus on describing simple experiment. You will learn the language structures that should be used for the description. In the second part of this unit you will focus on giving instructions, giving warning and explaining why you give them.

Objectives:
After this unit you should be able to:

describe an experiment,
state the recent results of an experiment,
report on the procedure and results of experiments,
give instructions and why they are important,
give warning.

Tasks and Dates

This unit consists of five activities.

To complete this unit you should go thought all activities. Contribute to all forums at least once. Go thought the quizzes.

Describing and experiment

First go through the list of materials needed to construct a potato gun. Read the steps. Then read the experiment description and results. Answer the questions in the Experiment quiz.
In the “Potato Gun” experiment, different verb tenses were used. Study the table below to make sure you understand their use.

Note

We use imperative to describe the method /steps (i.e. How the experiment should be carried out.).

1. Place the block on the table.

To describe the experiment itself (its demonstration) we use the present simple tense (active or passive) and future tense - will (i.e. We say what will happen.). We also use when/if …, it will …

When / If you push the potato, the volume of air will decrease. or When you push the potato, the volume of air decreases

To state the recent results of the experiment we use the present perfect tense (i.e. We state what has happened recently.). Not sure if this is very common -usually it’s stated as a present simple fact.

The increase of the air pressure has shot out the potato at the far end.

The increase of the air pressure shoots the potato out at the far end.

To report on the procedure and results of experiments, we use the past simple tense (active or passive). Both ends of the metal tube were plugged with potatoes.

Then go to the “Grammar quiz” and complete the sentences with the correct form of the verbs in brackets.
Finally go to the “Rocket experiment forum”. Study the instructions for the rocket experiment. This experiment is based on Newton’s third law. After studying the instructions, describe the experiment as if you were demonstrating it. Upload you suggestion to the forum.

Giving instructions

Most of you have already traveled by plane and you remember most of the instructions you get on board. Read the “Aircraft Safety Instructions” text and complete the table below it.

Aircraft Safety Instructions

1. All carry-on luggage should be safely stowed in the overhead lockers or under the seat in front of you.

2. In preparing for take-off, make sure your seat back is straight up and your tray table locked away.

3. Click your seat belt closed and fit it snugly around your hips. Seatbelts must be worn at all times when seated. When the seatbelt sign is turned off, you may move freely around the cabin. Return to your seat immediately if the seat belt sign is switched on and fasten your seat belt.

4. No smoking is allowed on this flight in any part of the cabin, including the toilet areas.

5. All electronic equipment including cell phones, electronic games and computers must be turned off now as they may interfere with the aircraft’s navigation system. When we reach our cruising height, computers may again be used. Cell phones must remain turned off until you are inside the terminal at our destination.

6. Right now the crew is indicating the nearest emergency exit. Count the rows from your seat to the exit. In an emergency, strip lights on the floor will guide you to the exit.

7. If oxygen is needed in an emergency, an oxygen mask will be released from above you. Place the mask over your mouth and nose and tighten the strap. Pull down on the hose to start the oxygen flowing. Make sure you put on your mask first before assisting others such as children.

8. Life jackets are found under your seat or under your arm rest. In the event of the plane having to land on water, put your head through the hole and pull the jacket over your head. Click the waist band clip and tighten your belt. To inflate your jacket, pull the tabs at the end of the chords. If more inflation is needed, blow through the tube on the jacket. Do not fully inflate your jacket until you are leaving the plane.

9. Look in the seat pocket in front of you for the safety instruction card. Please make yourself familiar with it as it explains the safety features of this aircraft.

Adapted from: http://www.teachingonline.org/airscript.pdf

Things you have to do on the plane.	Things you may do.	Things you should not do.

Then study the language that is used or could be used when diving instructions.

To give instructions use IMPERATIVE. Place the mask over your mouth and nose and tighten the strap.

To emphasize actions that are not allowed or dangerous use SHOULD, MUST. Seatbelts must be worn at all times when seated.

To emphasize you can use MAKE SURE. Make sure you put on your mask first before assisting others such as children.

To indicate that one action comes immediately after another use WHEN …., present tense. When we reach our cruising height, computers may again be used.

To say that one action has to be complete before another can happen use ONCE … Once you have put on your mask, assist your children.

To explain why or give a warning you can use OTHERWISE. Turn off your mobile phones. Otherwise they will interfere with the aircraft’s navigation system.

Sequencing: Before you begin …,First …,Then…,Next…, After that …

Now go to the “Instructions language” forum and suggest suitable endings for the sentences there.

Finally, go to the “Instructions” forum. Choose one of the tasks from the list and prepare some instructions for other students on how to do it. Think about the order they need to do things, problems they could have or any other things they should be careful about. Upload your instructions to the forum. Ask at least one question about your colleague’s instructions.
