B. Terraset Elementary school was built in the mid-197os, when the US was struck by the energy crisis. The country introduced energy saving mode, which was used for heating schools. The designers had a difficult task: the building below the surface of the ground was to be not only warm but also cool. This required new energy costs. The problem was solved with solar collectors. Today Terraset is not only the most energy-efficient school in the country, but also one of the major tourist attractions in the area.
C. School ALPHA, which opened its doors in 1972, is famous for disobedience. There are no evaluations, no strict schedule, and no homework. No one will punish you for writing with chalk on a blackboard. Pupils decide how to spend the school day and what activities to attend. Classes are formed not by age but by the students’ interests: along with Maths and spelling lessons students are provided by modeling, cooking and even basic philosophy. Another tradition is to hold meetings during which children as adults have the right to speak about the need for changes in the schedule of subjects and the system of school management.
D. In the past, the children of nomadic herders did not receive formal education or were forced to stay in boarding schools, and for months did not see their family.

In addition to the usual parking facilities there are school tents. Children are engaged in a special schedule. All schools for the children of reindeer herders in the national project have access to satellite Internet. After their homework or tests are checked the schoolchildren get the review.
