In space, there are extremes of temperature, high-energy particles and radiation from the sun, no atmosphere or atmospheric pressure. Living organisms must therefore be protected within a spacecraft or space suit. They must have a source of energy (solar panels or... read moreCategories: Lab/Student Activity, Lesson Plan, Unit Plan
In order to be in space, the spacecraft must get there. But it will immediately fall back to earth unless the effect of gravity is balanced by a high enough orbital velocity to keep it in orbit. In near-earth space, that velocity is about 7 km/sec, and is obtained... read moreCategories: Lab/Student Activity, Lesson Plan, Unit Plan
The sun’s mass makes up 99.8% of that of the solar system. The planets move around the sun in almost-circular orbits, all in the same direction, and almost in the same plane. They are kept in their orbits by the sun’s gravity. Moons orbit most of the... read moreCategories: Teacher Demonstration

In particular, the vast forests in British Columbia and Ontario provide the raw materials for a billion-dollar industry. Forests are also environmentally important as they remove carbon... read moreCategories: Teacher Demonstration
The cells of green plants contain the pigment chlorophyll in organelles called chloroplasts. Chloroplasts capture the Sun’s energy and store it―through photosynthesis―as chemical energy. The reactants for photosynthesis are water, H2O(l), and carbon dioxide, CO2(g).... read moreCategories: Lab/Student Activity, Lesson Plan
It is important that as human beings we reduce our ecological footprint. Human beings have impacted local ecosystems in a variety of ways, which can lead to endangerment or extinction of species and pollution. In areas that have been negatively impacted by human... read moreCategories: General Interest
