Year 4 Bio Blitz

1st March 2019
Each term, year 4 make a study of the field and compare the differences. This is called a Bio Blitz, this means a quick study of life. We collect data by looking at a grid with a hundred squares and recording the information that we find. We use a variety of ways to identify what we have found. We then look at how often a species occurs, for example if we find thistle in three of the squares that would be a 3/100 or 0.03 or 3%.
