• In your pair come up with ideas to protect the school environment
Task• Mr. Adam wants a detailed report on the trees in
Homewood. You will go to the woods and carry out a survey of all the trees
• You will record the tree types and produce a short report with graphs on the types of trees we have
• You will comment on
how we use the
woods
Method• You will be given a laminated A3 sheet
with hints on identifying the common tree types

your tally charts, the
laminated sheet and
a pencil
• Complete the following table as a tally

Survey time
• Now go with your teacher to carry out your survey
• If you cannot identify the tree in the field then bring a leaf back and we will try to identify it in the classroom
What did you find?
• Identification of trees is difficult, here is some help. Log on to the internet and try this link, you will need a leaf from the tree you want to identify
• http://www-saps.plantsci.cam.ac.uk/trees/
Results
• Write down your method (what you did). You need to write it in a way so that somebody else can go and do exactly the same survey
• Make a neat table of your results
Graphs
• You need to make some graphs of your results, consider
• Bar graphs: these will show how many examples of each type of tree there are
• Pie Graph: this will show the proportions of trees there are
Conclusion
• This is an important part of the report. You must make a concluding comment about the woods and your survey for Mr. Adam
Final Questions
• Do we need to do more to look after the woods?
• Should we consider ways to get more students using the woods (would this be safe)?
• Should we add more woods?
• Should we cut them down for buildings or playing fields?
