Burns and Streams

Activity Outline
The following methods for gathering information are addressed in the following fieldwork relating to the study of Burns
and Streams

• Using simple equipment to collect information (nets, magnifying glass, stopwatch, measuring tape)
• Observing wildlife
• Recording information on a simple plan/map
• Field sketching
• Testing an hypothesis
• Measuring the flow of water/current
• Using identification charts

Curriculum for Excellence Links
The study of Burns and Streams will help deliver the four capacities of the Curriculum for Excellence by encouraging:

• The recognition of the effect of the environment on the variation of plant growth
• The development of an appreciation of the variety of species
• The development of an appreciation of the natural habitats of wildlife
• The development of a responsibility for the care of living things
• The recognition of the effect of human interaction with the environment
• The appreciation of the benefits of being safe and responsible

Before You Go On Site
In order to prepare yourself and the children for a field studies visit to a local burn or stream it is important to outline
the activities that the children will participate in, the risks associated with working near water and the behaviour
which is expected at all times. The following activities could be used prior to going out on site:

Children
• Research and study various aspects of burns and streams e.g. plants, animals, birds, insects
• Practise with the equipment that will be used on the visit (equipment is available for loan from Countryside Services)
• Compose a water safety poster or story
• Discuss the worksheets which will be used during the visit

Teacher
• Teacher to visit site. Although local sites have been recommended through this pack it is essential that the teacher
   is familiar with the site before taking children out.
• Just before visit - discuss with pupils the importance of safety near water (e.g. water, stranger-danger, touching
  dangerous items etc)
• Prepare materials and equipment




                                                                                                     section two - wetlands 1

Fieldwork Summary
The following briefly describes the recommended activities for a visit to burns and streams in your local area:

1 Incorporate the walk to the site into the lesson by completing the observation sheet 1 “Look Carefully as You Travel
  Along”

2 On arrival at the site observe the landscape around burn and complete the sketch map using the key sheet 2 “A
  map of my section of the Burn”

3 Dip in the burn and list creatures and plants. Record this on Sheet 3 “What creatures can you find in the burn”
  and sheet 4 “Enlarged version of one of the creatures” sheet

4 Study the bed of the burn to test the hypothesis “The bed of the burn/stream looks the same everywhere” using
  sheet 5a (first level) and sheet 5b (second level)

5 Use “ Measure the rate of flow of the burn” sheet 7 to help you to determine the flow rate

6 Test the hypothesis "The rate of flow is greater when the burn is narrow" using sheet 6

7 Collect a sample of water for testing back at school

Sheet 2: A Map of my Section of the Burn
In the table below draw a plan of the section of river you have been looking at. Pretend you are a bird or in a plane
and draw what you can see from above – ‘A Bird’s Eye View’. Mark on any features that are in or near the burn. Use
the pictures (symbols) below to show where these features are. This is your KEY. If you find any others draw your own
picture (symbols) and add to the key.

Sheet 3: What Creatures Can You Find in the Burn?
Once you are ready start dipping in the burn and collecting some creatures to study in the plastic trays. Here is a list
of equipment you will need and the best way catch some animals.

You will need
1 A sampling net
2 A plastic tray
3 Plastic spoons
4 Magnifiers

You should....
1 Stand just downstream of your part of the burn
2 Stir up the mud and stones with your feet
3 Hold your net with its edge on the bed of the burn - wait for about 3 minutes
4 Empty your net into the water in the tray
5 Use the plastic spoons to scoop up animals to examine - you will find your magnifying glass will help
6 Your teacher will help you identify your creature using the key and identification sheets
7 Write below the names of all the creatures you have found




     PLEASE MAKE SURE THAT ALL ANIMALS ARE RETURNED TO THEIR ORIGINAL LOCATION


                                                                                                  section two - wetlands 5
Sheet 4: Enlarged Version of One of the Creatures
Draw an enlarged version of one of the creatures you have found in the burn. You may need a magnifying glass to see
the details of your animal.




                                                                                              section two - wetlands 6

“The rate of flow is greater when the burn is narrow.”

               True            False


                                                                                      section two - wetlands 9
Sheet 7: Measuring the Rate of Flow

The rate of flow can be measured by recoding the length of time it takes for a floating object to cover a measured
distance.

Equipment needed:
• Table tennis ball or orange
• Measuring tape
• Stopwatch

1 Measure out a five metre section of the stream
2 Drop the ball at the start point
3 Time how long it takes to cover the five metres
4 Repeat for another five metre section of the stream
5 Fill in the table below

 Test Two




If the answers are different can you work out why?
