This learning activity was done as part of a Biology in Fiji program. Forty high school students from Ontario travelled to Fiji to complete the SBI3U course. While in this case the blogging activity spanned the entire course as a major form of assessment, I have also done it as a smaller project within a course. For example as part of an ecosystem activity in Grade 9 Science.
