PRODUCT DESCRIPTION

Dichotomous keys are fun to use, but they are even more fun to make! After students have learned how to use a dichotomous key, get them to make their own! This activity will get them to truly understand how a dichotomous is structured and how it functions. This gets to the heart of how to classify organisms and hones their observational skills.

***************************************************************************

THIS PRODUCT INCLUDES:
1) Student instruction sheet with dichotomous key chart to fill in

***************************************************************************

STUDENT TASK:
They need to create a key (using the chart given) that successfully identifies all 9 organisms using only physical characteristics. They then need to create a spider key (graphic organizer) from their chart - this can be an optional activity if you want to omit the spider key. There are 9 organisms to classify and they each have been specifically chosen because they have easily discernible physical characteristics (hooves or paws, patterned coat or non-patterned, long tails or short tails etc.) Your student should have many physical traits to choose from when making their key.
