The Big6 is a six-stage model to help anyone solve problems or make decisions by using information. Students can use this model to guide them through the research process. This resource describes a Big6 lesson focused on the final step of the Big6 model, evaluation.

In this NASA video, scientists describe how the Extreme Ultraviolet Variability Experiment will sample and track the Sun's ultraviolet irradiance, providing a detailed time sequence of extreme ultraviolet output -- data that can provide advance warning for potentially disruptive energy bursts.

Nursery (or Kindergarten or Preschool) students enjoy seeing the evening sky with the teacher from the playground or through a big window (indoor). This is especially relevant for students who stay for extra-hour care. During late evening hours, some students feel a little lonely waiting for their parents, but they have a wonderful natural treasure: the evening sky. By observing the evening sky with the naked eye, they will notice many colours, changing colours, the first star, the subtle colours of stars, twinkling stars, and the movement of stars. Nursery teachers who think they are not science-oriented will also gain guidance skills of introducing science to students. This activity is also useful for primary school students, especially younger-grade students.
