In this activity, learners consider the requirements for human life beyond Earth's protection: air to breathe, plentiful food, shielding from ultraviolet light, power, etc. They then work in teams to design and construct a model of a space colony... (View More)

This is a lesson about the electromagnetic spectrum. Learners begin by arranging a set of picture cards; in the discussion afterwards, this activity is related to the electromagnetic spectrum as an arrangement of energy waves. Next, using a... (View More)

Students are introduced to the scientific tool of spectroscopy. They each build a simple spectroscope to examine the light from different light sources, particularly the Sun (Warning: Do not look directly at the Sun) and artificial lights (e.g.,... (View More)

In this activity, students are reminded that the Universe is made up of elements and that the heavier elements are created inside of a star, as they learned in the "Elements and You" activity. They are introduced to the life cycle of a star and to... (View More)

This is an activity about seasons. Learners begin by brainstorming a list of activities and events that occur in each season. Next, learners perform an experiment by comparing the temperature on thermometers left under a lamp for different lengths... (View More)
