Nests are important in protecting the eggs and young from predators and extreme temperatures. Discuss the words that are used to paint a sellable picture of the house. Have the students work in teams to create a nest of their own with the provided materials. The nest must keep the eggs safe and at a comfortable temperature. At the end have the students write up a real estate description of their nest to advertise the qualities of the nest that would be useful to its inhabitant.
Students can present their designs and ads to the class.
