They can bring in small pebbles and plants. Once the turtle is selected, the class can give ideas for names and one can be chosen. Have the children make hypotheses on what new foods they think their turtle would eat. Let them also suggest some things they think it would not eat. Each child brings in two items.
Children observe the different foods put in the tank each day and record the results.
They can log them in a journal about the class pet and write down other observations about sleep habits and behavior as well. They can also learn more about other turtles from the internet.
