Alternative titles: Dichotomous Key with Candy

Summary

Students practice classification by sorting different types of candy into groups based on shared traits, creating a dichotomous key that leads to the identification of each candy type. This models how scientists classify living things.

Procedure

  1. Gather at least 7 different types of candy.
  2. Place all candies on a flat surface and observe their characteristics (e.g., size, color, texture, wrapper type).
  3. Divide the candies into 2 broad groups based on one shared trait.
  4. Continue splitting each group into smaller groups using new traits.
  5. Record your steps on paper, forming a dichotomous key that eventually identifies each type of candy.
  6. Test your key by asking another person to classify a piece of candy using your guide.

Variations

  • Use other everyday objects such as leaves, toys, or school supplies instead of candy.
  • Compare how different groups of students classify the same set of items.
  • Extend the activity to living organisms (e.g., pictures of animals or plants) to connect to biology.

Safety Precautions

  • Avoid sharing candy if used for eating to prevent spreading germs.
  • Check for food allergies before allowing students to handle or eat candy.
  • Ensure small candies are kept away from very young children (choking hazard).

Questions to Consider

  • How is classifying candy similar to how scientists classify living things? (both use shared traits and sorting steps to identify items)
  • What traits were most useful in creating your candy groups? (e.g., hard vs. soft, wrapped vs. unwrapped)
  • What challenges did you face when creating your classification key? (some items share traits and could fit in more than one group)
  • How could you make your dichotomous key clearer for others to use? (use yes/no questions and consistent observable traits)
