Threats to Biodiversity Treasure Hunt – Teacher’s notes
This is an active learning task designed to consolidate the learning of this
subsection of biodiversity.
The first 12 pages of this document make up the questions (or clues) of the
task, page 13 is the student answer sheet and the last page lists the answers in
the correct order.
The design of the task mimics a simple loop game, with the answer to each of
the questions leading to the next question.
Step 1
Print off the first 12 pages of this document and stick them up at random
around the classroom.
Step 2
Issue students (in pairs or individually) with an answer sheet .
Step 3: Running the task
 Students may start at any question. The activity works best if each
student/team starts at a different question.
 Students read the first clue, which is the question in the centre of the page.
 They then look for the answer to that question, which will be in the topleft corner of another sheet of paper.
 It is worth pointing out that the answers and clues on t he same sheet have
no relation to each other.
 It is important that students do not write their answers down until they
actually see the answer in front of them.
 Once they have found their first answer they can write it down in any
answer circle on their sheet.
 They then write the subsequent answers as they find them in the following
circle on their answer sheet.
Step 4: Declaring a winner
 Impose a time limit on the task.
 Make a note of first, second, third on the answer sheets as they are handed
back in.
 Mark each sheet, with a mark given for each correct answer written in
succession.
 The winning student/team is the quickest back with the most correct
answers – in the event of a tie the quickest team is the winner.
The glory of winning should be enough to treasure!
