This is an ongoing activity that Joe is teaching with rotating groups of students. The students are learning various animals, plants, and fungi that compose a food web. Today Joe helped the students fill out and color a worksheet with a diagram of creatures that live in the soil and others that eat these soil-living critters. For instance, the worms eat the bacteria and the students must draw an arrow between the worm and the bacteria to illustrate this relationship. Birds eat the worms and nematodes, and arrows were likewise drawn showing this relationship.

When the students were done filling out the worksheet and connecting the various creatures to each other, Joe had them take on the roles of the animals and other lifeforms in the food web. When the students had decided who would be the worm, bird, bacteria, and the all the rest, they made larger artworks depicting the life form in question.

When the students were done with the food web activity Joe had them examine the seeds they started earlier in the paper towels.

Joe elaborated on the food cycle project the students worked on last time. In this session, the students played a game in which each creature was bound to the one it eats by a string. Each student, representing one of the critters in question, would pass the string to the critter that eats him or her. In this way the complexity of the food web was illustrated physically among the students.

Joe then had the students examine the seeds that had sprouted in the paper towels.
