Introduction/Motivation (Return to Contents)
How would you describe a tomato? (Listen to student suggestions.) Well, if you are looking at the tomato, the physical characteristics can be described as red and round. But, what if you could not see the tomato and could only describe it by touch? (Listen to student suggestions.) Then you could describe it as smooth and hard or soft, depending on how ripe it is. Would you be able to guess the object was a tomato if you held it in your hands while blindfolded? (Maybe smelling it would help!)
How else could you describe a tomato? Is it a natural-made or human-made object? What is a tomato used for? There are many ways to classify objects and put them into groups. With today's activity, you will sharpen your observation and descriptive skills.

Concluding Class Discussion
Lead a class discussion to review results and compare experiences. Ask students the following questions. The basic idea is that objects have certain characteristics that allow them to be grouped as similar objects, and that grouping can help you to understand and use these objects.
