Animal characteristics - number of legs

Summary: 
Look at real wood bugs, worms and a snake as well as a mammal. Sort the animals by the number of legs.
Science content (2016 curriculum): 
Biology: Features, Adaptations of Living Things (K, 1, 3, 7)
Science topic (2005 curriculum connection): 
Life Science: Characteristics of Living Things (grade K)
Life Science: Needs of Living Things (grade 1)
Life Science: Animal Growth and Changes (grade 2)
Materials: 
  • petri dishes, 5 per student pair
  • pond water/water with chlorine dissipated, for worms and wood bugs in dishes
  • tissue cut out for wood bug dishes
  • worms, one per student pair
  • wood bugs, one per student pair
  • picture of a mammal, one per pair
  • picture of a person, one per pair
  • picture of a snake, one per pair
  • number line (1 to 20), one per pair
Procedure: 

There are a huge variety of animals. We can start to understand this variety by looking at one characteristic (one part of it). The first characteristic we’ll look at is legs.
Open up the number line.
Put each animal or picture next to the number of legs it has. If you are not sure, don’t guess - look closely and you might have a better idea of the answer. Scientists often look closely to learn more about something. All the animals fit on this number line. [Worm 0, snake 0, human 2, mammal (usually) 4, wood bug 14].
