Here is an example of a classification key:
Classification keys are a means of identifying unknown organisms based on their distinct features. Keys involve a series of questions about an organism’s physical characteristics, with the answers branching off to other until the organism is identified.
When making a key, it is important that the questions must have yes or no answers.
Notice how you start at the top and work down to the bottom.
Main Activity
I would like you to design classifications for these objects
- Fruit
Remember that you need to ask questions that will split the group into 2 roughly equal groups each time.
Some suggestions for question areas:
- Do you eat the outside of the fruit?
- Is it round?
- Does it have pips?
- Is it smooth?
- Can you think of any other questions?
2. Musical Instruments
Please share your classification keys on ClassDojo.
You could also try to design a classification key for something else of your own idea:
- Liquorice Allsorts
- Celebrations
- Cartoon characters
- Books
I look forward to seeing what you come up with!
