Tank Engineering

Now that you have the eggs in your classroom, look at the way

the tank is set up and draw it below. Use a coloured pencil to

show how the water moves between the two tanks.

What is the purpose of the water filter?

To clean and circulate the water

What does the air pump do?

Aerates the water by bubbling air through it

What temperature do the fish need to be kept at and how are

we going to keep them cool?

The fish need to be kept between an ideal 5-10oc, maximum of 15oc,

this is done by changing the ice bottles at least twice a day

What are the pebbles for?

To give the alevins shelter

Alevin Habitat Conditions

What are the four things that eggs, alevins and fry need to

survive?

1. Clean Water 3. Shelter

2. Oxygen 4. Cold Water

How do we provide each of these things?

1. Water Filter and dechlorinated tap water.

2. Air pump and air stone.

3. Pebbles

4. Ice Packs.

Look at one of the alevins under a magnifying glass or

microscope and draw what you see. Label all the parts of the

fish that you can name.

Vessels

Trout Life Cycle

As a class make a Timeline to go above or near your hatchery.

The Timeline needs to highlight the key events in the Trout’s

life cycle and have information about each event.

Make the Timeline a work of art by using, photos, pictures,

drawings, and colourful writing.

So that everyone who sees your Timeline knows what stage

your trout are at make a marker out of string and an arrow

that can be moved along as your eggs grow.

Remember you will only have your trout for part of their life

cycle before they have to move to the river, mark this on your

Timeline too.

Here are some questions to help you out:

Where are the eggs laid?

A Redd

What are the hatchlings called?

Alevins

Why don’t the alevins need to be fed?

As they have a yolk sac

What are the young fish called?

Fry

After two years what are the young fish called?

Parr

When the fish get bigger where do they go?

To deeper bigger rivers or sometimes the sea as Sea Trout

What can happen to the adults after they spawn?

Some can die

Use books and the internet to help you make your timeline.

Fish Biology Drive

As a class or in groups play the FISH DRIVE game. The winner of

the game is who ever completes their fish drawing first!!!

You will need two dice

Have your pencil and paper at the ready

Take it in turn to roll the dice; you need to get a six to start the

game going as this is the body of your fish. Once you have the body

of your fish you can add on a part of the fish with every roll of the

dice.

Below is a key that tells you what number wins you which part of

the fish! Colour your fish in once they are complete.

River Conditions

Many years ago the River Clyde was full of strong healthy fish,

as towns developed and became more industrial the rivers got

used for shipping, ship building, trade and as a dumping ground

for rubbish and sewage. This caused a lot of the fish to die or

move away from the River Clyde.

Things are looking better now as the Clyde is gradually being

restored to a healthy river. Adult Trout and Salmon are

returning to the Clyde but a lot of the eggs, alevins and young

fish still die because they are weaker and the river is not

totally clean yet!

Think of all the problems that might be related to these

industries and how they will affect the fish in the Clyde.

Maybe work as a class to get as many ideas as possible.

Use the diagram on the next page to help you think about what

might affect the four necessities of fish life.

A couple of ideas have been added to help you, could some

things affect more than just one of the young fishes

necessities?

Insects

There are several different types of aquatic insects in Britain. They usually

have two stages in their life cycle. The first is a Larval stage, and the second

is called their Adult stage.

Using books and the internet research both life stages of aquatic insects.

Work as a team to produce a table all about the two life stages.

LARVAL STAGE ADULT STAGE

No Wings

Legs: So they can walk and

Crawl

Usually looks like a worm or a

caterpillar

Sheds skin frequently, this is

called moulting

Ultimate stage = Pupa

Have wings, therefore can fly.

Insects: lay eggs to reproduce

Shed their skin but less

frequently than larvae

15

Who Is Who?

Using the information you have learnt about insect larvae and

insect adults. Decide who is who, write LARVAE or ADULT under

the pictures.

If you need to, look back at your comparison table

Fish Foodweb

All living creatures have to eat to survive. Animals and humans eat a variety of different foods, but we all have our favourites.

A FOOD WEB is the cycle of smaller animals and plants being eaten by larger animals and then these animals get eaten by even bigger

animals!

Below are pictures of different animals and plants. Either cut and paste the pictures or carefully using scissors cut the pictures out and

add them to the diagram overleaf in the correct places. Don’t forget to identify all the plants and animals, the names at the bottom of

the page should help.

The water droplets join together to form clouds

The sun heats the air above the surface of the ocean causing water to evaporate.

As the warm moist air rises it begins to cool and water droplets are formed

As the water droplets collide and get bigger the clouds become darker as they contain more water.

The water droplets eventually become so

heavy that they fall as

RAIN!

The rain falls on the land and flows downhill due to gravity

The water flows into the folds on the land to form burns and streams

As burns and rivers flow downstream they meet up and join with other burns, this is how rivers grow!

The river enters the sea at its estuary

Water Cycle

Earth is the only planet in

our solar system which has

water. The amount of water

on earth is constant, it

never changes. The water is

used over and over again,

this process of re-cycling is

known as the “water cycle”

Opposite you can see a

picture but the words have

fallen off!

You can find the missing

words on the next page.

Carefully using scissors cut

out the pieces and stick

them in the correct place.

Design your own Game or Book

Use all the information you

have learnt about Trout

and their life cycle to create a Game or

a Book that will help yourself and

others learn and remember

the Trout's story.

Things to think about

Game

How many people can play?

How do you win?

What props do you need?

What’s the name of the game?

What are the rules?

What do you learn?

Are there any special tricks or

moves?

How old do you need to be to

play?

Book

Remember: Start, Middle and

End

Are there pictures in the

book?

Is it a comic?

What age group is it aimed

at?

Who’s the main character?

What tense is it in?

Is it all fact or is there a

little fiction?

What is the title of the

book?

24

Newspaper Editor

With all your ideas create a newspaper article about the

problems that the young fish have to overcome.

Look at newspapers to get ideas about layout and what is

essential for a good newspaper article.

All the water in the

World!

There is 1,386,000,000 km3 of water in the

world. But as you learnt from the water

cycle this can be found in several different

forms and locations.

Below is a table that gives percentages and volumes of water and

where that water is found in the world.

Can you complete the table so each location has a volume and a

percentage?

Location Percentage of

water %

Volume of water

Km3

Oceans 96.5% 1,337,490,000

Atmosphere 0.002% 27,720

Rivers 0.004% 55,440

Ice 1.75% 24,255,000

Lochs/Lakes 0.014% 194,040

Underground

water 1.73%

23,977,800

Total 100% 1,386,000,000

Using graph paper or a computer can you make a graph to show the

different amounts of water in the different locations?

Things to think about:-

What type of graph?

Colours?

Labels?

Title?

Are you using percentages or the volume of water?

26

All this water and not a drop to

drink!

The water on earth can be split into

salty seawater and fresh river water.

Humans, animals and plants can only

drink freshwater.

But only 2.6% of all the water on earth

is fresh water.

1.82% of this is locked away in ice

sheets and glaciers!

This leaves only 0.78% available in rivers, lochs, and underground

which is safe for us to drink!!

If there is 1,386,000,000km3 of water on the earth how much is

safe to drink?

How many ways do you use water and can you guess how much?

1 Shower 11. Car washers

2. Bath 12. Fish Tanks

3. Brush teeth 13. Farm irrigation

4.Washing machine 14. Fizzy drinks industry

5. Water plants 15. Mineral water producers

6. Drink 16. Cook

7. Wash hands 17.

8. Toilet 18.

9. Gardening 19

10. Dish washer 20.

Work out your answer here

1386000000 / 100 = 13860000

13860000 x 0.78 = 10810800
