Sampling techniques: Difference between revisions

|content=An activity based on four different organisms: the butterfly, the oak, the whale and the zebra.  

The lesson follows on from a series of preceding practical investigations in the school grounds. During these previous lessons students will have experienced a variety of sampling techniques such as use of quadrants, leaf litter sampling, ‘tree beating’ sampling and so on. This lesson takes the sampling techniques question into a ‘real life’ scenario that they may not have encountered.  

* Analysis of the scientific articles thereby supporting exploration and data analysis.<br />

* Collaborative learning by working in a group to prepare and produce the poster together.<br />

* The second meeting around the poster supports consolidation.<br />

* The presentation of the poster supports presentations skills.<br />

 

 

* '''Small group work''': the investigation by the groups followed by reporting back to the class

* '''Whole class dialogue''': there is discussion for each of the 4 different organisms

* '''Open ended questions''': there is potential to probe why is one sampling technique different to another “How do you explain the x result…?”

* '''Peer assessment''': do peers agree with the analysis?

* '''Project work''': students are exposed to different sampling techniques

* '''Enquiry based learning''': the initial presentation to the class can be framed as a problem for students to solve

* '''Co-enquiry''': students work collaboratively

* '''Arguing & reasoning''': there needs to be discussion as well as debate & persuasion for consensus

* '''Exploring ideas''': there is development of the understanding of Scientific principles and techniques e.g. sampling methods vary according to species.

 

This is an investigation linked to group work and presentation of posters.

 

 

 

This lesson is following students practical experience with sampling methods. The lesson should increase the students understanding of sampling methods and expose them to real scientific use of these methods.
