Candy Classification
N Pirzada. Published: 2.27.2015 Kitchener-Waterloo Collegiate and Vocational School

To classify candy genera and make a dichotomous key by making a detailed comparison based on the phenotype of each species. Fourteen different species of candy were observed by their physical characteristics. The genera were divided into two categories repeatedly until a species was identified. Some of the classification methods used were the divisions of species by colour, shape and exterior wrapping. All species were identified, but many of the species had similar physical characteristics to each other. Five candy species had a heart shaped body. Five candy species had exterior wrapping. Three species were in the colour red and some species have red included in their body colour (Purple Heart Candy). However, some of the rare phenotypes included a cylinder shaped sticks attached to the candy (Red Heart Lollipop and Yellow Lollipop), malleability as a physical property (Caramel Toffee) and candy coated with sprinkles and sugar (Chocolate coated with sprinkles and Purple Irregular Gummy). To conclude, all species were successfully identified by making detailed comparisons of each species’ phenotype and making a dichotomous key to organise the divisions.

To identify different candy species by observing the phenotypes of the candy genera and constructing a dichotomous key. To make clear differentiation of the species by creating divisions into two categories until each species is identified.

1. Find a general physical characteristic that allows you to separate the bag of candy into 2 groups.
2. Find another characteristic that allows you to further subdivide each group from step 1 into 2 groups.
3. Continue until all the candy has been classified into a branching diagram. The last “leaf” on each “branch” should be the name of a specific candy.
4. Use the branching diagram for your candy classification to create a dichotomous key as a series of numbered questions.
5. Have another student test your dichotomous key to ensure it is clear and functional.
