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.

Yolk Sac
Tail Blood
Vessels
Fat Gobules

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?

might affect my

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.

Fish Foodweb
Can you work out which two livings things are at the top of this small food web?? (hint – where do the arrows stop??)

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?

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
