Flowers and Bees
Bees and flowers are a natural combination. In fact, the flowers provide food for bees. While some flowers could survive without bees, many species of flowering plants would go extinct without bees to transfer their pollen. This is because the flowers do not produce enough pollen to be transferred by wind or other methods.
Chemical Reactions
Chemistry is a great home study science. Kids of all ages can work together and still study curriculum appropriate for each individual age. This can be achieved by using fun and easy investigations that can be expanded to provide enrichment for more advance studies. An example is the chemistry of rusting.
Birds: Wild Bird Identification
I have a bird feeder that hangs outside my office window. While I love watching birds, I've never considered myself a "Bird Watcher."
Science Magic: Inertia
Newton's laws of motion describe the relationship between the forces acting on a body and the motion of the body.
Newton's First Law of Motion: This law describes inertia, which means a body will stay at rest or continue at a constant velocity unless acted upon by an external unbalanced net force.
Example of the inertia of [...]
The Longest Day
Sunflowers are a sign of summer. But, astronomers can tell you the exact day and even the moment that summer officially begins. This moment in time is called summer solstice .
In 2009, in the Northern Hemisphere, summer solstice is on June 21 at 1:45 EDT (eastern daylight time).
While this is called the longest day of each year, it is only [...]
Red Eye
Photographs with red-eyed subjects are becoming a thing of the past because cameras are flashing twice. What causes red eye? How can a double flash prevent it?
The pupils in your eyes are really holes covered with see-through skin. Objects appear red in color because they reflect red light. The back of your eye reflects red [...]
Ceres – A Dwarf Planet
Most asteroids are irregular, rocky chunks of matter which orbit the Sun. Until 2006, Ceres was considered to be the largest asteroid with a diameter of about 600 miles (960 km). It was not its size that changed its classification, instead other physical features were the deciding factors that boosted the hunk of rock into a [...]
