Background For Teachers:
The cards and the key for this activity are located in the web sites under the "materials section."
Intended Learning Outcomes:
Step 2. After all the items have been discussed, the students are to place the materials into two groups. After all the items have been categorized, each group should write a short explanation of the basis of their classification scheme. This should be kept secret.
Step 3. Have all the groups trade trays. Now, using the new tray, observe the objects and try to guess the basis or rules used to group the objects.
Step 4. Compare the guesses with the explanations and discuss.
Step 6. Pass out the sets of animal cards to each group. Have students sort all the animal into 2 groups. Students should decide on the characteristic to use (e.g., those with wings,those with legs; only eat plants, only eat meat).
Step 7. Have students record all the characteristics they can that would divide the animals into 2 groups. Remind the students that the 2 groups do not have to be equal in size.
Step 8. Have each group share one animal classification rule they used with the class, and then have the rest of the class name the animals that would fit. Discuss:
Step 9. Distribute the Key and choose one of the animal cards (such as puppy) and work it through the key to name its classification as a group. Then give groups time to work through the key with each animal card and decide upon its classification. Discuss any differences of opinion and reinforce the idea that as long as a classification can be backed by logical reasoning, it could be accepted.
Have students fold a paper into two columns. Select 2 classifications and have them label the columns accordingly. Example: four legs and no legs. Have students list as many animals as they can that would belong in each column. At the bottom of the page, have them write a sentence that explains what a classification system is("When you classify, you put stuff into a bunch with stuff that's like it") and why it is useful to scientists ("Classification systems help scientists better study things.").
